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?</P></BODY></HTML> Tue, 27 Feb 2018 10:18:51 GMT mykhayloshcherb 2018-02-27T10:18:51Z K28 flexio 8080 4 bit lcd display with dma https://community.nxp.com/t5/Kinetis-Microcontrollers/K28-flexio-8080-4-bit-lcd-display-with-dma/m-p/777485#M47316 <HTML><HEAD></HEAD><BODY><P>I'm trying to use UC1611s display in 4bit 8080 mode with Flexio and DMA.
