read bit from byte

[the_weasel]

How do I read one bit in a byte in PCM 4.037? For this specific example I am reading a byte from a register over SPI and only care about bits 7, 3, 2, and 1. The rest are don't care. I can read the byte just fine, but, I'm stuck figuring out to to only look at the bits I care about.

To mask off bits you can use the bitwise AND (&).

See #bit in the CCS manual for how to assign variables to individual bits in a variable.

You can also use bit_test() to test the state of bits in a variable.


PCM, Thanks for catching my error in the mask info and letting me know! (now corrected)
