Hello,
I can’t integrate the WPSE342-board with an ESP32S via I2C. Testing the I2C connections, I see the board’s address, but using the demonstration software (downloaded .ino), it doesn’t work. I have an LCD hooked up to the line, and I see 3 devices:
I2C scanner. Scanning …
Found address: 39 (0x27) => my LCD**
Found address: 91 (0x5B)** => CCS811 gasdetector CO2, on the default address.**
Found address: 119 (0x77)** => BME280 temp/hum/p sensor I assume ?**
Done.
Found 3 device(s).**
Now, in the demonstration program the CCS811 is defined with the address on I2C, but the BME280 is not.
Using the found address 0x77 in the program gives an error.
Either way, the program doesn’t succeed in reading either of the devices. Even when only one device is left in the program and when the LCD is removed. The chips don’t react to the program.
Am i using the wrong GPIO’s on the ESP32? AFAIK, wiring is correct.
This is the sensor board in question:
Looking for Help
Tnx, Jan
