hi
we talk just in time the I²C glitch problem in arduino esp32 core.
not tested just in time, but makes sense:
at we have:
to change it to OPEN_DRAIN only?
i can test earliest this on weekend with OSC ( RIGOL )
best wishes

Code: Select all
gpio_set_direction(scl_io, GPIO_MODE_OUTPUT_OD);
gpio_set_direction(sda_io, GPIO_MODE_OUTPUT_OD);
Code: Select all
gpio_set_direction(scl_io, GPIO_MODE_DEF_OD);
gpio_set_direction(sda_io, GPIO_MODE_DEF_OD);
