I have decided to add two new peripherals to the Trinity Complexes.
The first is one that will drive a 2x16 LCD. It will do the initial set up of the display and then on a timer update the display continuously. This will be possible as the 'fabric' is designed to do this as a non block matrix. It will do the carriage return for the second line. I just need to work out how to manipulate the cursor on the display. This will take up 32 bytes of memory.
The second will read out memory and display on a 128x64 matrix LCD. This will mean that a 1kB memory will need to be used. Again this will be a timed update. I will be interesting to see how it goes.
In the meantime I shall continue to investigate the Uart and see if I can get it to work as expected.
