Bit banging I2C

Open abbrev opened this issue 4 years ago • 4 comments

Hi @threeme3, is there a reason that I2C is bit banged on pins that support hardware I2C? Specifically in class I2C:

https://github.com/threeme3/QCX-SSB/blob/57e438da4425f3d22deb9ba9b5e64167a20d67b2/QCX-SSB.ino#L768-L775

We can probably at least reduce the code size a little by using the hardware I2C (though it probably wouldn't reduce the CPU load since we'd still have to synchronously wait for each byte to transfer).
