Long SPI distance problem with 2 Slaves.
Posted: Thu Dec 06, 2018 3:18 pm
I Have 2 SPI modules on Raspberry SPI0.
When i connected 1 Short cable slave it is working
When i connected 2 Short cables slave it is working
When i connected 1 Long cable(7 meters) slave it is working
When i connected 1 Short, 1 Long Slave, both are not working!
if distance is problem, why 1 Long Cable is working? What is changing 1 Long 1 short cable situation?
