- To write a program in assembly language, select Microchip MPASM Tool-suite and to write a program in C, select HI-TECH Universal TOOLSuite.
- If a cross marking is shown on the left side of the tool contents, then select that particular tool and browse its corresponding .exe file at the location path provided and click ‘NEXT’ to continue.
- Step 7: Go for Browse, Save the project in a suitable location with appropriate name
- Step 8: Click Next to the following window open.
- Step 9: Click Finish to the following window open.Thus create a project with project name ‘Sample‘.
- Step 10: Create a new file either by clicking the New File icon,or by selecting File > New or using keyboard shortcut CTRL + N
- Step 11: Save the file in the appropriate folder by File >Save as or by save icon
- Step 12: Thus save the file with .c extension
- Step 13: Now type the code in the c file
- Step 14: Add the c file to the project by right click over the Source files and select
- Step 15: From the following window select the proper c file and click ‘open‘
- Step 16: Thus add the c file
- Step 17: Now compile the code by selecting Project<Build or Build with compiler icon as shown below. Errors(if any)get listed in the Build output window.Correct them and build again.
- Step 18: To Specify ROM ranges, select Project >Build Options…>Project>Global>ROM ranges from menu. Type the ROM ranges as shown below . Then click Apply and OK.
- Step 19: The controller can burn using either Pickit2 or serially. If you are using Pickit2, then you should select the proper configuration bits ( you can skip step19 for serial programming). Select configure> configuration bits…untick the option configuration bits set in the code. You can set the bits as shown below. After selecting proper configuration tick the option configuration bits set in the code and build the code.
- Step 20:On successful building, the hex file will be generated in the project folder. And output window will be as shown below.
- Step 21: Now the code can be flashed to the controller.
On the board, make sure to do the following jumper connections
- Select the power source as USB cable or DC source.
- Select USB or serial port for flashing the code.Now power up the board. The power LED on the board glows. Open Tiny Bootloader(Download),
Step 22: Open the Tiny Bootloader
Step 23: Load/Browse the required hex file. A window opens as shown below.
- Step 24: Select the required hex file and click ‘Open’. Select the correct COM port recognized by PC and if its more than COM5 change it to any any lower COM port in Device Manager and select suitable baud rate.
- Step 25: Click Write Flash(in Tiny bootloader) and simultaneously press Reset button in the on-board mini development board. After successfully flashing the code, use controller for the desired purpose.
