## Serial Setup ## Serial Setup
To communicate with the Apple 1 you need to use the second channel serial interface for the iCE40HX8K-B-EVN board. This should appear as a COM port on you PC. This project is configured to use the 12MHz onboard clock to generate the baud rate, and as such I've selected 4800 baud (8/N/1) as this was the only baud rate that rounded nicely to 12MHz without an error rate.
