Good morning all,
I am writing to you because I have an existential question ...
I use a teensy 3.6 which controls 25 digital potentiometers in SPI. Unfortunately, I do not have enough CS pins available.
After much research I have two solutions at my fingertips, and I don't know which is the best one to give me my 25 CS pins.
The first solution is to use two 74hc154 logic demultiplexers.
The second solution is to use two MCP23S17 expander.
Which do you think is the best? If you have other solutions I take them with pleasure
Thank you for your help Jérémy
