Re: I2C reading data from MPU 9265

I've retried the code using the initialization brackets to zero the struct, but the error still remains (263 timeout error). Do you think that there could be something wrong with the timeout limit? I've tried making it larger or smaller, but the problem still remains that it is thinking it has not r...

I thought this was very strange, but I tried it on two ESP32s, one brand new, and they both had this strange issue. Perhaps it is the Espressif board that is causing it someh...

I2C reading data from MPU 9265

I've been trying to read a register from a MPU 9265 9DOF IMU, but I have been continuously met by an error code (-1) each read. I have run code on an Arduino to verify that the IMU works, and it works fine. That code is here (https://www.luisllamas.es/usar-arduino-con-los-imu-de-9dof-mpu-9150-y-mpu-...
