Hello!
I'm using Tiva c (TM4C123GH6PM), and on SSI0 a found something that I can't understand. I've already tried to search for it but it wasn't successful.
So, the thing is that I want to interface with an sd card through spi bus, and MOSI pin gives 5volts, while the other pins (cs, clk) gives 3.3volts. On MISO pin the sd card provides answers on 3.3volts.
What I don't get is, why is the difference between the MOSI and the other pins voltage level?
Thanks for your help!
Deni
P.S. Sorry for my bad english.
