i bought a Dragonboard and i try to connect the Dragonboard and a MCP3008.
I have done it with a Raspberry (where it worked like a charme) and now i want to move the installation to my Dragonboard.
if i read out the MCP, there are only 2 possible values i get back: either 0 or 1023.
I can't tell, why i get back 0 or 1023 or even have any influence on which value comes back.
i am using the right pins on the low-speed connector.
I already got another board.... same thing.
Any hints where i could start looking for problems?
Is the SPI on the Dragonboard different then the one used on the Raspberry?
Thanks for your help!
