I'm trying to use UC1611s display in 4bit 8080 mode with Flexio and DMA. I'v modified SDK flexio_mculcd to support 4 bit bus witdth in blocking mode by using two transactions. But with dma flexio sends less significant 4 bits first. How can I swap nibbles to send 4 most significant bits?
Sorry, I'v missed register with swapped nibbles. It works now
