nice little project, i made one but it doesn't work, don't know why. the only difference i made in it, is to begin in address 0 of the I2C bus. I put the bme280 in sda0and the sreens in 1, 2, and 3. Mod in the code is just call TCA9548A(0) for the bme, and 1 to 3 for the screen. As it wasn't working, i add some pull up resistors on the sda and sck ligns but it produce the same result. could someone help me?
