Getting a rotary encoder to work reliably
Because a gray code should only change one bit at a time, bounce will only be a problem it it lasts past the next bit change position. The effect will be dithering back and...

Detecting RS485 idle
If you give each slave 2 addresses that differ only by 1 bit (top or bottom is easiest) and you use the 9-bit system to mark address bytes, the overhead on polling is greatly...
