4ch adc records on sd card

[STobo.1]

Hello,

I try make a program for record on sd card a data/values from 4 channels adc1.

First I make program for read a 4 channels from adc1 and it works!

When I pause a debug in while loop, in uint32_t adc[4] I have all 4 correct values.

Then I make a program for write some data to sd card it works!

When I check sd card on pc; after debug; I have new file.txt with data 😉

So when I just make active a adc1 in cubemx for sdcardonly project and try run in on truestudio, nothing with previous issues works! -.-...............

Please help me or just give me some clue.

Use a merge tool, and make sure you've pulled over all MSP initialization code, as well as all interrupt code

Too many files attached.

look at now 😉
