Thanks. It indeed was the BMP280 sensor and the new code did the trick. I'm still having problems with the DS3231 though, but I think the SCL pin is causing the error : once it's plugged in, it causes the TCA9545 write control register function to fail. Is there another way to test it?Also, I recently received the ADS1015 ADC for the wind vane, and I've plugged it in, as well as shorting ADDR and GND to use 0x48 as the address. However, the I2C Mux board test code doesn't seem to detect it (it's -- instead of 48). Is it dependent on the DS3231 being plugged in, or do I need to connect something from JP8?Thanks for the advice!
I've started on this project, and followed the wiring instructions. I'm running the testSDL_Pi_TCA9545.py to see if the i2c mux board is wired correctly, but everytime i plug the DS3231 RTC into the weatherPiArduino weather board, the python test program fails at line 58 (tca9545.write_control_register(TCA9545_CONFIG_BUS0)). Do I need to insert a pull up register for the 32k line, or something else? or is the DS3231 or WeatherPiArduino board faulty?Any advise would be appreciated. Thanks in advance.
