Interfacing (DSI, CSI, I2C, etc.) • Re: TomTom Display datasheet link
Easy to connect to RPI DPI interface, but as it consumes all GPIO the question remains if it's worth the effort for such a low resolutuon display.A 4in SPI gives you 480x320pixels at far less effort...

The behavior of the pull-ups was also interesting. With pins set to inputs and pullups on, and then switching from inputs to outputs, the output pins are always initially set to zero, then switched to...

Turns out the RX pin on GPIO21 isn't an issue. The QT Py exposes TX and RX so of course both can be used on the same UART; UART1, GPIO20=TX, GPIO5=RX - Which is how 'stdin/stdout' does it as shown...

No I would say, it looks to me that you are experienced enough handling a Pi4 and various software. You can try OMV, it offers lot with nice interface, but I found that it lacked various key features...
