WebApr 8, 2024 · While all lines are working in terms of SCK, MOSI and MISO, I've noticed that the chip select line goes low much longer than necessary and seems to be triggering off around 20kHz as opposed to the 2MHz SPI. This is a problem as the slave I am using triggers off the CS line and during multiple SPI calls the data becomes corrupted.

WebMay 6, 2024 · The Due only allows a fixed set of pins as SPI CS (chip select, not slave select as you say), 10, 4 and 52 (being NPCS0/1/2) The NPCS3 signal is not routed to one of the Due header pins I believe. SPI cannot work unless using one of these pins. You can toggle other pins too around the SPI calls, but you have to use one of these hardware pins. trusted sites group policyWebMay 6, 2024 · I have a sketch which is written for an SPI OLED display.
