It works somewhat, it is displaying things. I just need to fine tune a few things like making sure all of the correct inputs are paired with outputs etc. On the OE and SRCLR. Hypothetically I could hook OE to a pin and make it low, and the SRCLR set it high right? Also what are the two different chips? The SPI is a synchronous serial data protocol that the atmega has that allows for serial comms. then what controls the rx and tx on the board? Are they two different parts of the MCU or are they totally different components? Thanks
