LCD Connection for 20A MPPT

Hello, I’ve been seeing through the schematic of the 20A MPPT, with a reference of mail you replied you stated using OLED Olimex, How do I use another type of display for this as OLED isn’t available within reach. And what’s the connection protocol.

You can basically use any OLED or LCD with SPI, I2C or UART interface, as these are all available in the UEXT connector.

There are lots of mbed libraries for different displays available. Take the interface to the oled as an example to implement your own display interface:

You can find the pin names in the firmware in pcb subdirectory.
