Ive got a new project in the works as I thought it was high time I made use of the NPU in one of my VIM3’s…
But to get this new project working i need to be able to control two SPI slaves from the VIM3 - is it possible to get two slave select / chip select lines on SPI_B? Looking at the A311D datasheet / VIM3 schematic SPIB_SS0 is on Pin15 of the GPIO header, is it possible to assign one of the other GPIO pins to use as a second chip select line? The hardware bit is easy I can just wire the pin up but how can i make linux work with it?
I cant use SPI_A as (again looking thru the A311D datasheet / VIM3 schematic) then some of these pins are used for the wifi chip.
Was hoping to be able to drive both SPI devices from the VIM3 without having to put in any additional chips for translation
