A/D conversion using PIC16F74

[jazzyflymc]

Hi,

I'm using an PIC16F74 for reading & transmmmiting (to a bluetooth module) 8 signals from 8 pressure sensors. Using only one of the 8 inputs would be simple, but I can't figure out how to write the assembler code for using all 8 PIC inputs (that is changing to the next input each time a A/D conversion has been made by reading 1 of the 8 inputs, and than starting all over again).

I would be gratefull if someone that has done this job before could provide me the code.

Thanks

Check my PIC tutorials which explain how to use the A2D converters, be aware though that speed of changing inputs is highly dependent on the source impedance feeding the inputs.
