Pic microcontroller analog to digital converter module has five registers. nRF24L01 Assembly Code. Flow Chart: (Note: The structure of program code is a little different from flow chart, due to it being necessary to orga-. In the case of 0x0f, the 0 is in the high half, and the f is in the low half. The above snippet is to add two numbers and does what the algorithm below does. movlw 0x0F W = 0x0F • If X = 0x0F and N = 0x02, clear the lowest two bits—bits 0 and 1. Looking at what is happening on the bus will tell you whether (a) the data sent from the sensor really is all zeros - in which case your likely problem is with the commands. I have made a routine of interruptions, for the PIC16F84, very simple, to turn on an LED when I press a button and the steps. Updates *New!
