Thanks for the guide! I tried this, only for the touch screen since I am using an HDMI monitor, but it's not working.
It is a 5" waveshare clone (v2)
I scoped the spi bus and the interrupt pin. I see some strange characteristics.
SCLK is fine:
MOSI is only driven to ~1v
MISO is less than a volt:
And the interrupt on PA1 is ~0.5v
I am using an orange pi pc plus on 4.14.84
Anyone have some idea of what might be going on?
