Re: i2c_master_cmd_begin Timeout Error lasting 1000 ticks, despite much shorter timeout setting

At my side the problem has been solved by enable interrupts: ESP_INTR_FLAG_INTRDISABLED is not OK

This works:

Code: Select all

i2c_error=i2c_driver_install(I2C_NUM_0, I2C_MODE_MASTER,0,0,ESP_INTR_FLAG_LOWMED);

My slave send an ACK but the master timout after the eighth bit. You can see on the attached image that my slave maintain ACK. Then afte...
