CCS/F28M36P63C2: Using the M3 SCI Interface with the LCD

Part Number: F28M36P63C2

Tool/software: Code Composer Studio

Hello,

I am trying to interface with a Crystalfontz_CFAL1602C LCD. It's driver/controller IC Facilitates 4 bit parallel, 8 bit parallel and Serial communication via SPI. I am currently designing software for battery charger and i have used a lot of the C28 peripherals and GPIO's on my design to generate ePWM's and ADC conversions. I was thinking about using the C28 SPI peripheral to inerface with the LCD but now i feel it would be wise to use the Master SCI peripherals instead of congesting my C28 with more functions. Is it even possible to achieve this by using the SCI master peripheral?? How does it differ fro mthe SPI interface in the C28??

Thank you,

Srini,

As you know, your LCD driver/controller was designed to work with SPI and not SCI. There is not a way replicate SPI functions with SCI. To learn more about the differences between the communication modules (note that they are not at all compatible), please see the appropriate chapters in the F28M36x TRM, which can be found at:
