hardware spi pins?
-
what are the hardware spi pins on the headers (if they are on there at all)?
-
Hi @ramon-schepers, hardware SPI pins are not available on the Omega because it is being used for the flash storage. We've found that that using the hardware SPI pins sometimes corrupts the data on the flash storage, so we decided to not connect it out. We are working on a library to bitbang the SPI using GPIOs.

Is there a rough ETA for that library?

Looks like with a bit more hardware you can run SPI over I2c

@Lazar-Demin, thanks for that - if it's that close, I can be patient.
@Andrei-Railean - that was my original thought - the need for I2C, SPI and RS-232 coming from the Omega - going that way still may be the best option. Bit banging RS-232 at the speed I need maybe doable, but wasn't so sure for SPI.

@Malcolm-White the SPI library is finally here!
Sorry for the wait, I continuously had to interrupt my work on this library to assist with other tasks, thanks for your patience.All the info can be found on our wiki:
