  1. ELEC 4601 Microprocessor Systems Lab 5 Tutorial Introduction to PIC Board

  2. No more MASM • Lab 5 • Introduction to MPLAB IDE • Create a new project • Compile a project • Transfer the program to the board • This lab will have 3 parts. They will involve polling timers and setting up interrupts.

  3. PIC Board

  4. Wiring up the board LEDs

  5. PIC board with debugger

  6. Introduction to MPLAB IDE • Start MPLAB IDE v8.15a • Select Project • Select Project Wizard… • Click Next • Device -> PIC16F917 • Click Next • Active Toolsuite -> HI-TECH Universal Toolsuite • HI-TECH ANSI C Compiler • Click Next

  7. Continued… • Create New Project File • Choose an existing folder or create a folder and choose a file name and click save • Click Next • Skip Step Four by clicking next • Select Finish • Create a new file by selecting File -> New • Save file as ‘.c’

  8. Compiling your project • Type in the following: #include <htc.h> void main(void){ } • In the project window, add the .c file to list of source files. • Click Project->build.

  9. Programming the PIC board • Click Pogrammer • Select Programmer • Choose MPLAB ICD 2 • If you do not see “MPLAB ICD 2 ready for next operation” message in the output log window, then select Programmer->Settings. Ensure that the settings are as follows: • Under communication tab: Com Port is set to USB • Under power tab: Power target circuit from MPLAB ICD 2 box is checked

  10. Continued… • Select Program • Click Program

  11. Program Bring board out of reset

  12. Register Access • Table 2-1 to Table 2-4 outline the register map for PIC processor. • They can be accessed by simply assigning them a value. • The following statement will clear Timer 0 TMR0 = 0x00;
