This presentation will help you to test the examples included with the software package and in that way get acquainted with the most frequently used features of PIC10 Simulator IDE.
Example 1: demo.bas
Example 2: demo2.bas
Example 1: demo.bas
Examine demo.bas file from the application folder. This program first writes 32 bytes of data to an external 24C256 I2C EEPROM and then verifies the operation by reading the data back. During these operations formatted text is transmitted by a software implemented serial port. File demo.asm was generated using integrated Basic compiler. File demo.hex was generated using integrated assembler.

Return
- Start PIC10 Simulator IDE.
- Click on Options\Select Microcontroller.
- Select 'PIC16F506' and click on Select button.
- Click on Options\Change Clock Frequency.
- Enter '4' and click on OK button.
- Click on Tools\BASIC Compiler.
- Click on File\Open.
- Select demo.bas file and click on Open. The basic source program will be displayed in the editor.
- Click on Tools\Compile & Assemble & Load. The compiler will generate demo.asm file with assembler source. The integrated assembler will assemble that file and make demo.lst and demo.hex files. Demo.hex file will be loaded into the simulator program memory.
- Click on Tools\Software UART Simulation Interface. That will open the Software UART simulator window.
- Click on TX Line label on the Software UART window and select PORTC.5 pin.
- Click on Tools\I2C EEPROM. Another simulation interface will be displayed.
- Click on SDA Line label and select PORTC.4 pin.
- With similar procedure select PORTC.3 pin for the SCL Line.
- Reposition the windows on the screen to get better view. If needed use Always On Top option on the windows.
- Select the Rate\Extremely Fast simulation rate.
- Check that Options\Basic Program Tracking option is turned on.
- Click on Options\Infinite Loop Stops Simulation to turn on that option.
- Click on Simulation\Start. The simulation will start immediately.
- Watch the simulation on the main simulation interface, Software UART and I2C EEPROM simulation modules. Around 10ms of real simulation time will be necessary to pass to see the first activity on the Software UART module. Watch Real Time Duration field.
- The simulation can be stopped any time by clicking on Simulation\Stop. Otherwise, it will be automatically stopped after the whole program has been simulated and infinite loop has been detected.
- Try to run the simulation in Step By Step mode. Then use Run To Next Basic Statement command.

Example 2: demo2.bas
Examine demo2.bas file from the application folder. This program reads analog value on AN2 analog input and transmits formatted output by a software implemented serial port. That value is also displayed on PORTC pins. File demo2.asm was generated using integrated Basic compiler. File demo2.hex was generated using integrated assembler.
