The code is very simple I wouldn't have posted, the i2c 100 k,
Hardware in order to prevent other factors, I only took the VCC GND SCL sda, 4 lines
Oscilloscope and sequential logic analyzer:
Yellow for SCL, blue for the sda,
Tested many times back and forth, changed many parameters, card for several days, was the feeling,
Thank you very much!!!!!!
