Introduction
1 INTRODUCTION
The ST623x Starter Kit provides you with all you need to start designing, developing and evaluating programs for ST6230 and ST6232 microcontrollers immediately. The ST623x Starter Kit includes: * The ST6 assembler and linker, AST6 and LST6. * A demonstration of the ST6 application development tool, ST6-Realizer. * The ST6 Windows debugger, WGDB6. * The Windows ST6 microcontroller programmer, Epromer. * The ST6 Starter Kit board, which serves as a demonstration board and low-cost debugging tool. * Some demonstration programs that show how ST6 microcontrollers use the Starter Kit board resources. * Some example programs. * One ST6230 and one ST6232 microcontroller. * A complete set of paper documentation and online help. The demonstration programs, that come pre-loaded on the ST6232 microcontroller, show how the powerful features of ST6 microcontrollers operate in a real environment. The demonstration programs use the hardware resources provided on the Starter Kit board, which include reset and data control buttons, LED indicators, a voltage control oscillator, three 7-segment displays, a resistance trimmer, temperature control circuit and an RS-232 interface. Using the ST6 assembler and linker, AST6 and LST6, you can assemble and link ST6 programs. The AST6/LST6 User Manual will guide you through the steps of developing, assembling and linking programs for the ST6. The Starter Kit software includes a set of example programs of typical ST6 applications. These are installed in the directory C: \ST623x \examples. For a fast-track solution for developing bug-free programs for the ST6, without the hassle of writing assembler code, try out the ST6-Realizer demonstration. Once you have developed your ST6 program, you can use the Windows-based ST6 program debugger, WGDB6/SIMULATOR, together with the Starter Kit board, as a low-cost but powerful debugging tool. WGDB6 includes an ST6 simulator, that simulates the execution of your program, and uses the ST6 that is plugged into the Starter Kit board to emulate all transactions that are performed with the data space. Thus, using the Starter Kit board with WGDB6, you can view how the microcontroller pe-

ripherals behave when your program is executed. WGDB6 includes powerful debugging features, such as source-level debugging, instruction and conditional memory access breakpoints and selective trace recording. The WGDB6 Getting Started manual and online help will lead you through the debugging process using WGDB6. When your program is ready, Epromer provides you with an easy-to-use Windows interface, which lets you prepare executable code, then write it to the ST6 microcontroller that is plugged into either one of the DIL sockets on the Starter Kit board, or your own in-circuit application board that is connected to the Starter Kit board. To observe and evaluate the consequences of your program on the resources it controls, you can run it on an ST6 microcontroller that is plugged into the Starter Kit board. If it controls a resource that is not included on the Starter Kit board, you can connect your own resource to the board. Instructions for use - Warning This product conforms with the 89/336/EEC directive; it also complies with the EN55022 emissions standard for ITE, as well as with generic 50082-1 immunity standards. The product is a Class A apparatus. In a residential environment this device may cause radioelectrical disturbances which may require that the user adopt appropriate precautions. The product is not contained in an outer casing, and cannot therefore be immune against electrostatic discharge (ESD): it should therefore only be handled at static safe work stations.

2.8 Temperature Control Circuit This circuit demonstrates temperature control, using the on-chip A/D converter. A Heater resistor circuit (150, 1 Watt) is driven by the TIMER output of the ST6232 microcontroller. The heat level can be controlled by varying the duty cycle of a PWM signal present on the TIMER output. The Heater circuit can be disconnected from the TIMER output pin by removing the W7-TIMER jumper. A thermistor bridge (Negative Temperature Coefficient) is connected to the PC6 I/O pin, which is programmed as an A/D converter input. The voltage value at the A/D converter input decreases as the thermistor temperature increases. The Thermistor circuit can be disconnected from PC6 by removing the W6 jumper. The thermistor is located in close proximity to the Heater resistor on the Starter Kit board, so that it can be used as a sensor to detect the temperature of the resistor body. Demonstration 6 shows how this circuit is used as a feedback loop that controls the temperature level (see "Demo 3 - Temperature Control" on page 18).

The Starter Kit Hardware
2.10 Demonstration Selector Jumpers The demonstration selector is made up of a 6-position jumper W1 (marked 2 on the Starter Kit board diagram on page 9), with each jumper connected to a resistor. Each resistor generates a different voltage. After reset, the voltage value generated by the resistor whose jumper is installed is sent to PC7 on the ST6232. PC7 is programmed as an A/D converter. The program installed on the ST6232 uses the input from PC7 to select the appropriate demo. The following table lists the voltage values generated by each resistor:
Resistor value: R2: 10 K R3: 680 R4: 750 R5: 820 R6: 1 K R7: 1.2 K Theoretical voltage value: No JUMPER: 5 V JUMPER-D1: 0 V JUMPER-D2: 333 mV JUMPER-D3: 666 mV JUMPER-D4: 999 mV JUMPER-D5: 1.332 V JUMPER-D6: 1.539 V
The same principle can be used for keyboard decoding. For a complete example of this, refer to the SGS-Thomson application note: "AN431: Using ST6 Analog Inputs for Multiple Key Decoding". You can disconnect the demonstration selector from PC7 by removing the PC7 jumper from W1 (marked 2 on the Starter Kit board diagram on page 9).

2.11 Frequency Measurement This application simulates the servo-control of a motor's speed using a regulation loop. The 16-bit Autoreload Timer output PWM generates a frequency of about 15Khz. You can increase or decrease the duty cycle of this frequency using the "+" and "-" buttons. This frequency is then filtered to produce a proportional DC voltage of between 0 and 5 Volts, which attacks the voltage control oscillator (marked 6 on the Starter Kit board diagram on page 9). The voltage control oscillator produces a frequency at its output in the interval of 50Hz-1Khz. The 16-bit Autoreload Timer measures this frequency through its input port CP2 with a frequency precision of 1/100. The result is displayed on the three 7-segment displays. Demo 5 demonstrated this process (see "Demo 5 - Frequency Measurement" on page 19). The Frequency Measurement circuit can be disconnected from the CP2 input and the PWM output by removing the corresponding W8 and W9 jumpers.

Running the ST6-Realizer Demo
5 RUNNING THE ST6-REALIZER DEMO
ST6-Realizer is a Windows CASE tool that enables you to develop high-quality applications for the ST6 family of microcontrollers. Using ST6-Realizer, you design your application by drawing symbols and wiring them together. Each symbol represents a process, such as adding two values, and is linked to an ST62 assembly code macro. The wires represent the flow of data, and are linked to variables and constants. You can attach attributes to symbols and wires, in order to attach extra characteristics to them. For example, attaching an attribute of type UINT to a wire defines its value capacity to that of an unsigned integer (0 to 65536). When using ST6-Realizer, you design your application in schemes. A scheme is like a sheet of paper on which you place symbols and draw wires. Each application is designed on one scheme. To install the ST6-Realizer demo: 1 Place the diskette labelled "ST6-Realizer Demo disk" into your floppy disk drive. 2 In Windows Explorer or File Manager, browse the contents of the diskette, and double-click the Install icon. To run the ST6-Realizer demo: If you are using Windows 3.x, double-click the ST6-Realizer demo icon in the ST6 Tools group. If you are using Windows 95, click Start, Programs, ST6 Tools, then the ST6-Realizer demo.

Using The Starter Kit Board as a Hardware Simulator
7 USING THE STARTER KIT BOARD AS A HARDWARE SIMULATOR
WGDB6, the ST6 debugger that runs under Windows, lets you test your programs without having to program the EPROM of your target ST6. Depending how much information you want, and how close to real life you want your test environment to be, you can use WGDB6 in one of three ways: * As a software simulator. If you use WGDB6 as a simulator, you need not attach any additional hardware to your PC. The ST6 simulator program, that comes with WGDB6 and is run when you run WGDB6/Simulator, simulates the execution of your program, letting you step through the code and see what happens as the program runs. WGDB6 simulator includes Wave Form Editor, which simulates the output of the pins on your target ST6 in relation to inputs that you define, enabling you to see how its peripherals react to the inputs they receive. * With an ST6 hardware emulator. Emulators are hardware systems that act as your target microcontroller, at the same time capturing detailed information, such as which areas of memory are accessed by the program and what happens when they are accessed. In this case, WGDB6/Emulator provides an interface between the emulator and your PC, displaying data captured by the emulator and letting you implement the WGDB6 features in the emulator, such as software or hardware breakpoints. * With the Starter Kit board as a hardware simulator. This is a cross between the above two. The WGDB6 software simulator simulates the execution of your program, but each time the data space is accessed, it accesses that of the ST6 that is plugged into your Starter Kit board. Thus, using the Starter Kit board with WGDB6, you can view how the real microcontroller peripherals behave when your program is executed. This section describes the third option, how to use the Starter Kit board as a hardware simulator. You can use the Starter Kit board to emulate any ST6230 or ST6232 microcontroller. Note, however that you must use the pre-programmed ST6232 microcontroller, labelled DEMOK32 supplied with the kit for hardware simulation. Thus, when simulating programs designed for other microcontrollers, make sure that you do not use resources that are not available on the microcontroller your application is designed for.

Using The Starter Kit Board as a Hardware Simulator
7.1 The Data Transmission Driver Data is transferred between the simulated peripheral registers and the ST6230 or ST6232 registers via the host PC's parallel port. The DEMOK32.HEX program, with which the ST6232 microcontroller that is plugged into the Starter Kit board must be loaded includes the transmission driver. The data transfer driver uses the following bits:
PC ST6232 parallel port D2 PE2 D3 PE1 D4 RESET D6 NMI SDOP PE0 SIMULATOR USAGE Synchronisation Write data to MCU Hardware reset of peripherals Initiates data transfer Read data from MCU
7.2 Technical Limitations The Starter Kit board has the following limitations when used with WGDB6 as a hardware simulator: * Real-time program execution is not supported. * Resetting the ST6232 by power on, pressing the Reset button or external reset does not reset the simulated ST6 core. To perform a complete simulated reset, use the WGDB6 reset command instead. * Interrupts sent by the ST6232 microcontroller are not supported by the WGDB6 simulator. * The pins: NMI, PE0, PE1 and PE2 on the ST6232 microcontroller are used for communications with the host PC, and are thus not available for simulation.
NOTE: Do not connect any external resources to the corresponding J2 connector pins when using the Starter Kit board as a peripheral emulator.

Programming ST6 Microcontrollers
8 PROGRAMMING ST6 MICROCONTROLLERS
You can use the Starter Kit board, in conjunction with the program Epromer, to program ST6230 or ST6232 microcontrollers. You can also perform in-circuit programming of ST6230 or ST6232 OTP/EPROM microcontrollers using your own board, connected to the Starter Kit board via the connector J1 (marked 1 on the Starter Kit board diagram on page 9).
NOTE: The PB4, PB5, PB6, PD2, OSCIN, OSCOUT and RESET pins are used to perform programming operations. If these pins are connected to an external resource via J2, you must either disconnect them (see "Connecting External Resources to the Starter Kit Board" on page 23) or set them to high impedance state during programming operations.
This section describes how to set up the Starter Kit board for programming microcontrollers, and lists the connection requirements for in-circuit application boards. 8.1 Setting Up the Starter Kit Board 1 Power down the Starter Kit board. 2 Plug the ST6 microcontroller you want to program into the appropriate MCU socket on the Starter Kit board. 3 Select the PROG mode using the jumpers marked W2 (marked 20 on the Starter Kit board diagram on page 9), as shown in the diagram below: W2
MODE
4 Connect the Parallel port P1 on the Starter Kit board to a spare parallel port on your PC using the cable provided with the starter kit. 5 Power up the Starter Kit board. You can now use Epromer to program the microcontroller that is plugged into the Starter Kit board.
NOTE: Epromer does not work under Windows NT.

For instructions on how to operate Epromer, click Help in the Epromer main window. 8.2 In-Circuit Programming You can perform in-circuit programming of ST620x, ST621x or ST622x OTP/EPROM microcontrollers using your own board, connected to the Starter Kit board via the connector J1 (marked 1 on the Starter Kit board diagram on page 9). 8.2.1 Application Board Connections The following paragraphs specify the connection requirements between your application board and the Starter Kit board. The application board must have a suitable 16-way connector (8x2 header HE10) to be connected via a 16-way cable to connector J1 (marked 1 on the Starter Kit board diagram on page 9) on the Starter Kit board. The following table shows the required pin connections:
ST6230 and ST6232 PB5 PB4 OSCin PB6 RESET PD6 VPP/TM VDD VSS Connector Pins Pin 1 Pin 3 Pin 5 Pin 7 Pin 9 Pin 11 Pin 13 Pin 14, 16 Pin 2, 4, 8
VDD Use of the VDD connection is optional, depending on whether the application board supply can or cannot be disconnected. If the application board supply is disconnected, you can supply it through pins 14 an 16 of the connector, as long as the total load current does not exceed 100 mA, and the capacitive load is less than 50 F. If the application board has its own power supply, its voltage must be set to 5V, so that logic levels are compatible with those of the Starter Kit board.

Programming ST6 Microcontrollers
OSCin Synchronises the programming operations using a clock generated by the programming tool. OSCin is located on the application board, and must be directly connected to Pin 5 on the 16-way connector. No isolation is needed as long as a quartz crystal or ceramic resonator is used in the application. If an external clock generator is used in the application, it must be disconnected during in-circuit programming. RESET Controls the programming mode entry. To prevent signal level contention, RESET must be directly connected to Pin 9 on the 16-way connector, and must be isolated from other nodes on the application board. Any direct connection to V DD, VSS or an output must be avoided. This pin can be connected to a CMOS input, a 2 K pull-up, a 10 KOhm pull-down or left open (Internal pull-up). The capacitive load of the RESET pin should not exceed 1 F. Pins 1 and 7 on the 16-way connector are used to establish communications between the programming tool and the microcontroller. To prevent signal-level contention, Pins 1 and 7 must be directly connected to PB5 and PB6 on the 16-way connector, and must be isolated from other nodes on the application board. Any direct connection to V DD, VSS or an output must be avoided. These pins may be connected to a CMOS input, a 2 K pull-up, a 10 KOhm pulldown or left open (Internal pull-up). If pin 3 on the 16-pin connector is connected to the target device, the same applies. Connection to pin 3 is not necessary if a high voltage level is guaranteed by the board design. Some I/O pins are not connected to the 16-way connector and must be set to a high level during programming. This is normally achieved by the RESET signal sent by the programming tool through the 16-way cable, setting the I/O pins as inputs with an internal 300 K pull-up. To keep these I/O lines high, direct connection of these pins to GND or to any other signal at low level (even temporarily) must be avoided. Only connections to another CMOS input, to an external pull-up or a 10 M pull-down is allowed. The Vpp/TM pin must not be directly connected to GND/V SS on the application board, to avoid any conflict with the programming voltage provided by the programming tool via pin 13 on the connector. This pin should be pulled down by a resistor with minimum value of 10 K. You must add a 100 nF ceramic capacitor between Vpp/Test and VSS.
