Use your LEDs

  • Indicate phases of program operation by illuminating LEDs. In particular a lot of electrical faults cause the PIC to resst. The first thing your code should do is illuminate a "startup LED" for 100mS. If you see that LED flashing repeatedly, you'll know your PIC is reseting.


Why is my PIC reseting?

  • Often from spikes. Add more 1uF capacitors near your digital chips, especially H-bridges.


Runs only with ICD unit attached

  • Make sure you are not in debugger mode. Try adding the NOBROWNOUT fuse at the top of your code.
