Hi, I have 2 TCA9548A I2C Multiplexers connected to a ESP32. Also connected 2 I2C sensors with same addresses to each of the TC9548A on different channels. How do I call each of the TCA9548A I2C MUX with their address to read the sensor data continuously in a loop? So far I can only read the senso…

Try this and see if you get any better results: #include <Wire.h> #include "MPU9250.h" // an MPU9250 object with the MPU-9250 sensor on I2C bus 0 with address 0x68 MPU9250 IMU0(Wire, 0x68); MPU9250 IMU1(Wire, 0x68); int status; // #define I2C_ADDR 0x68 #define TCAADDR0 0x70 #define TCAADDR1 0x71…

This will show you how to use it. [image] Adafruit TCA9548A 1-to-8 I2C Multiplexer Breakout You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about …

First question would be why you have 2 TCA9548A chips? And the second one is why you have your sensors connected to two different TCA9548A chips? Are you planning to use up to 16 of those unknown sensors in your setup? Life would be a lot easier if you connected both sensors to the same TCA9548A.

Didn't you post the same question a couple of weeks ago? In setup, you are calling the begin() function for each IMU unit twice, once for each IMU before selecting any of the multiplexer channels, and again for each IMU after selecting its respective multiplexer channel. In both setup and loop, yo…
