I am using pi3, grove to pi connector hat, and the weatherboard on your SSD. I have the rtc, the barometer and light sensor connected. When I run sudo python testSDL_Pi _TCA9545.py
I get the following

Test SDL_Pi_TCA9545 Version 1.0 - SwitchDoc Labs

Sample uses 0x73

Program Started at:2019-02-27 14:30:03

Traceback (most recent call last):

File "testSDL_Pi_TCA9545.py", line 51, in <module>

tca9545 = SDL_Pi_TCA9545.SDL_Pi_TCA9545(addr=TCA9545_ADDRESS, bus_enable = T CA9545_CONFIG_BUS0)

File "/home/pi/SDL_Pi_GroveWeatherPi/SDL_Pi_TCA9545/SDL_Pi_TCA9545.py", line 4 7, in __init__

self._write(TCA9545_REG_CONFIG, config)

self._bus.write_byte_data(self._addr, register, data)

IOError: [Errno 121] Remote I/O error

Can you help me out here?

Do an "i2cdetect -y 1" and post the results. BP

I am getting a little mixed up with the wiring.

Help me out here. Remember, the i2C bus is a BUS and the I2C Mux converts the I2C bus to four separate busses. BP
