I’ve been setting up the optoisolators (H11L1) for SPI. Because they invert the signal, you have to switch the clock polarity, polarity for CS, and take the complement of the data (A->0xFF-A). I used magnet wire for some practice, because it’s supposed to be good for fine SMD stuff.
I still haven’t programmed the ads1299 over this, there’s some issues I need to work out. All I can say is….
