Removing HDMI transmitter and altering firmware #46

Closed mackieks closed 4 years ago

mackieks commented 4 years ago

I'm modifying the OSSC design to drive a TFT LCD directly through the 24-bit parallel RGB interface, so I am removing the IT6613E and the PCM1862 from the PCB. I've been looking through the firmware, and it seems the softcore configures the IT6613E and PCM1862 quite a bit over I2C. Do the I2C libs used strictly require an ACK from the IT6613E and PCM1862? My project would be much more straightforward if I didn't have to go down the rabbithole of modifying the firmware and removing all I2C comms with those two ICs.

After doing some more digging, I found marqs' old DE2-VD repo, which is a much better starting point for a barebones scan conversion project.
