[Lilygo TTGO] From T-Display to T8
I'd like to move from a T-Display controller to a T8.
The original application used pin 21 and 22 for TX and RX respectively, but the pins are numbered differently on the T8.
Before I pull the soldering iron… can I just update and recompile the source code to use any IO pin I want instead?
T-DISPLAY uses ESP32
T-DISPLAY-S2 uses ESP32-S2
As shown in the figure below, in addition to the already used IO ports, you can freely allocate available IO ports
