During the last 3 days, I could not work a lot. Indeed, I made some tests about the oscillator on the testing board. To make that tests, I need to use my Windows Virtual Machine but I don’t know why, the board connects its to the Windows machine and disconnects. So I can’t use the board’s software. However, the board does not sometime unplug and I can make some tests. I tests different configurations thanks to some jumpers. I tried to use the internal clock of the ADC but when I disabled the extern oscillator, the acquisitions did not work. If my computer will allow me to use the software, I am going to make some tests to know if the ADC need a bipolar or an unipolar supply power.
I reviewed the analog part of the schematics too. And, after the tests, I will see it again.
