Hi all, I had made a sample program to transfer data via DMA to a USART. Reason is that I wanted to understand how DMA works on a PIC Microcontroller.
I now added a sample program to Jallib to transfer a JAL logo to an ili9341 LCD and compare the data transfer speed without DMA and with DMA. For this demo I used a PIC18F15Q40 and needed the SPI and Stopwatch librares but they did not support this newer PIC so I also updated the SPI, SPI2, Stopwatch en Stopwatch2 libraries to support this PIC. Although it worked OK for USART it did not work for SPI and I could not explain why. So I posted my issue on the Microchip Forum and after some hints I got it working. I made a video of this demo: https://youtu.be/nlHEFFp2E1E Last but not least, a Happy New Year!
