Yes, the logic analyzer tests the ESP pin to have signal pulses. x but only all high or all low levels when passing 595

It may be that there is a problem with the quality of the 595 components, and the speed is not enough, so I will re-order a few 595s to try...

Test the clock directly from the esp32 pin with only 4.8MHz

yes,unpluged from hc245. I use esp32-wroom-32e/esp32-wrover-e If you're using a wrover do not use pin 18 for output because it's linked to the psram. Maybe change this in your code

Thank you for your answer. I'll try again
