Indeed there are, the asm should have caught that. Also, the reset int vector should be on top of the list, with "rjmp start" So it would look like this: reset: rjmp Start (rest of int vector table etc) Start: Init code goes here Main App code goes here rjmp main On Thu, Feb 14,

Here is some starting help: I did a pwm thermal controller. I used a TEC (thermo electric cooler) that I controlled with PWM thru an IRF530 fet. I also used a Dallas 1 wire temp probe for feedback. I used a PID loop for temp regulation. See: http://tech.groups.yahoo.com/group/Mea

Too quick with the send button... If your main program is nothing but a series of calls to subroutines, you can divide and conquer by commenting out a particular subroutine during test in order to see if that's where your problem is. This also allows for easier simulation and tes
2008-02-05 by Roy E. Burrage
To add to this, building your program as a set of modules makes this process a lot easier. Your main program would be a series of calls to subroutines that would return to the main program when they're done doing what ever it is they do. Doing a flow chart helps in this process.

This is a part of the art that isn't taught much.. How to diagnose or debug a problem. Basically, you need to divide up your system, to know that "THIS PART WORKS", and keep sectioning off the problem into a smaller and smaller space until you have it cornered. I learned this art
