  • Possible to read from/write to the SD card using the serial RX/TX on board?

    Like title says, I wanted to know if it is possible to read from or write to the uSD card using the serial communication port that I use to program the PICASO microcontroller with.
    I have the 3.2" screen with GFX firmware. Also have a usb-to-serial kit (FTDI) that I use to program the chip with. If this is possible it would be awesome as I can just log events into the SD card and read them with the USB cable I have.

    Thanks!!

    Of course you can, you just need to write the program.

    BTW you should get a 4D usb to serial adapter (CE5, MB5 or programming cable). Non-4D adapters/cables are not designed to reset the display properly and may cause the display to be bricked during a PmmC update.
