@AnthonyMyatt This would be fantastic. A pull request for this would be excellent. Perhaps a second PR rather than together with the waveforms PR?

Given that the Raspberry Pi 4 supports up to 6 hardware UARTs, the need for adding bitbanged support for UARTs is not necessarily what it was in the past.

I'll go ahead and close this as the Raspberry Pi 4 supports up to 6 hardware UARTs and the need for adding bitbanged support for UARTs is not necessarily what...

@pow4all as mentioned in issue https://github.com/fivdi/spi-device/issues/26, I would imagine that the problems that you are having are related to your system setup.
