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!

Kind regards,

Rob
