During this end of week, I worked on the electrical schematic. Unlike Xavier, my task was to make the analog part of the schematic. I began to understand the schematic of the test board with which we have made some tests to watch ECGs signals. As we had good results for the ECG signals, we want to use some components of the board for the analog section.
I made tests to know if the ADC which use needs an external oscillator and if we need an unipolar or a bipolar supply power but with those tests, I could not make a conclusion. I think I did not put the electrodes at the right position or I used the software with a wrong configuration. So, the next week, I am going to make again this tests and revise the schematic.
Have a nice end of weekend,
