Hi gilshultz!
Thank you for the SWAG! Been checking the LCD board pinout / driver terminals and function and this is what I’ve got:
I can see that the basic power supply pins are there. The driver seems to be forced to work with Channel 1 through SHL1 (connected to GND). Then the latch, data and shift signals are available.
If I’m not wrong, the common I2C display driver has a way to work with this. I will try to connect the LCD board to one of these modules and see what can I get...
Keep you posted!
Kind Regards,
Mariano.
