JAL is a free language (compiler) for the Microchip 16f84 and Scenix SX microcomputers

Having had some troubles with jal and the PIC 16F877, the following helped me a lot

  • have a test program ready for all connected devices
  • do rs232 first - stop debugging with LEDs
  • don't pass variables to procedure and functions
  • don't give up - try simple stuff first
  • speed wloader up to 28'000 - you'll save a lot of time
  • don't pass variables to procedures, don't use functions
  • be careful with the 2 PWM outputs - they use the same PR2
  • check your batteries - the PIC goes crazy when voltage gets low.
