There is an SDK example for the K28 that uses parallel FlexIO output with DMA to control an LCD display.
I am trying to configure this exact scenario on an IMXRT1052, but I am having trouble getting the FlexIO parallel data pins to output anything.
Has anyone converted or attempted to convert this example?
I have attached the code from that example (for MCUXpresso IDE).
I'll post my modified example if I get it working.
Also referenced in this old thread: When will "FlexIO driver for LCD(8080/6800)" be released in RT1050 SDK?
