I've written a program that just sends out 32 lines with 80 characters at 115200 Baud.
The aim of this program was to show I can control the screen appropriately. The timing turned out to be below the Doherty limit with timing loops to do the delay between characters to be sent out.
This means that I have all the information needed for the creation of the block to send a memory area to a serial port. This will assume a dedicated Serial TX port for the display.
The next step will get to see data coming down the line to Trinity and then displaying it.
