ESP32 Forum

I am trying to use the esp32 ULP for I2C communication with mpu6050 using the commands I2C_RD and I2C_WR given in coprocessor instruction set on https://docs.espressif.com/projects/esp ... n_set.html.
I tried searching for ULP example programs using I2C_RD and I2C_WR commannds for I2C communication. But couldnt find any. Has anyone developed programs using the commands. Could you help me with the same.

The native i2c instructions can only do single bytes

@Wifive - I have recently come across codes which utilise bitbanging, but didnt find any for interfacing mpu6050.
Also I would be grateful if i could find codes which utilise the native commands as I just have to read the interrupt register in mpu6050 to see if the mot_thr interrupt is raised, when the ulp wakes up.
