I am working on STM32F405 and MCP3428 (ADC).
If i read all channel independently (i.e only one at a time)then everything works fine.
But when i try to read all channels simultaneously then i face a problem.
Problem:
-Addresses of channels get shifted like Shift registers.
-Means Channel 2 gave channel channel 1 reading
Means Channel 3 gave channel channel 2 reading
Means Channel 4 gave channel channel 3 reading
Means Channel 1 gave channel channel 4 reading
-Addresses of set channels are Okay.i tested it independently.
Searching the datasheet for "simultan.." gives only one occurance.
And this talks about simulataneous conversion of different devices, not different channels.
Please clarify.
Your code could give a lot of information .... to see what you are doing.
