spi1.send(b'com1,com2')
Code: Select all
spi1.send(b"\xfe\x42")

However, I can't find a suitable library or class for it. Is there any way to use it? Thanks for your help in ad...

I forked from the repository mentioned in the first post of this discussion, and made all needed changes. Also added a working example. Tested nicely with ESP8266. The cod...
