Hello Michael,
Thank you for your answer. That is true, SPI driver's initial flag setup is
0.
The flags are evaluated dynamically and very meaningful
within spi_exchange() and set via
sam_dmaconfig(spics->rxdma, rxflags);
sam_dmaconfig(spics->txdma, txflags);
I will try with setup initial f
Hello Simon,
I did take a look into SPI driver for SAME70 a few months ago. The one thing
that was a little bit weird to me was the lack of DMA flags passed to sam_
dmachannel() function (somewhere here https://github.com/apache/incubator-
nuttx/blob/master/arch/arm/src/samv7/sam_spi.c#L2043) co
Dear all,
I'm using ST7789.c in combination with lvgl-lib.
The bottleneck to the display is the SPI communication. But even if I
increase the SPI frequency to 24MHz, it does not get faster. This is
because of constant delay between the bytes.
I guessed that this can be improved using DMA. But th
