*bah* that's not working close to silicon *g*
We design our own boards and I make reccomendations on the pre-production
boards. And every time I need to support something I wrote I usually go
down to the drawing level. My desk is full of schematics. Then I single
step through the asm just to make sure the compiler gets it right (it has
known to buck up before* TTL I/O would be awesome if that's all I had to
do, but throw in some SPI bus, CAN, serial (485,232), EEPROM (also SPI
bus) and things get real dicy at times.
One time I had to use the 12CE519 which has no (read: ZERO) interrupts on
it and the customer wanted it to do some timing, as in three separate
timers running concurrently at different lengths) That code was a work of
art. My masterpiece. *grin* And I dare anyone to try and understand it.
*grin*
