I would like to ask what GPIO pins are best suited for Chip select. The Raspberry Pi 3B+ and Raspberry Pi 4 has 2 chip select GPIO 7 and GPIO 8 but i have 6 slave devices (MCP3008 A/D converter). As far as im aware it possible to use ordinary GPIO as chip select.
My Pis have not arrived yet from order, and in the meantime i have started to design my pcb. Which led me to the delima of what are the best GPIOs for SPI chip select that will give me the least trouble coding later on
