Parent article: Drivers as documentation

Haven't written device drivers for a few years now, I miss it, but careers change in unexpected ways, and I doubt anyone would hire me for that now. But one of the most satisfying aspects was debugging the datasheets. Some were just slipshod and done in a hurry and fairly easy to figure out even before writing code. Some were horrible; I have memories of some Motorola QUICC chip which listed about 17 steps before even blinking an LED, and they had steps 8 and 9 misplaced or reversed or some such, in a completely non-obvious way.

Hair pulling while it went on, but as progress was made, satisfaction grew, and the final victory was sweet indeed.

Thanks for the memories. A part of me hopes the engineers are never given so much time and incentive that the datasheets are always correct ...
