WebMay 4, 2014 · 1. This is a C thing. You want to do the shift on a 16 bit value. If you shift a 8 bit value by 8 you will get zero (bit fall off the left side). Hence ( (uint16)adch) + adcl. 2. On avr, the h/l values of a 16 bit register must be read in a certain order. Otherwise it's not an atomic sampling of the value. http://www.nerdkits.com/forum/thread/2599/
