Hi, I use 'X2' pin for measure the frequency, I have a square signal input on the pin. The signal frequency is 1hz. I use a µs timer. I use ExtInt for detect a rising edge and count time between two rising edge. Frequency = 1 / Period Frequency in Hz Period in second Well, my period is in µs So, Fre...

Thank you for your answer, I have tested my alimentation with an oscilloscope. I viewed a variation. The variation wasn’t detected with my cheap voltmeter. So, I decided to change my alimentation and the issue was almost resolved because my second alimentation have only few variations. The world isn...

HI, I use an analog input. I use with a bridge voltage divider Theorical : Vin max = 15v R1 = 68KΩ Vout max = 2,711 R2 = 15KΩ (i use an electrodoid to get the value) For testing: Vin = 8,61 R1 = 67900Ω (measured with a multimeter) R2 = 15050KΩ (measured with a multimeter) Code used  boot.py and test...
