Hi everybody,

I'm using for the first time a PGA (Programmable Gain Amplifier) and I don't know how to use it.

I'm using a MCP6S91 , an one channel amplifier.

And I want to interface with a PIC18F4550. I'm using MPLAB and CCS C Compiler
Can somebody help me?

Thank you!
 

The PGA is programmed through a Serial Peripheral Interface (SPI). The PIC also has a SPI interface. Now you need to go read about SPI, and about how to implement it in your PIC.
