First of all, I'm a newby so there is a possibility I didn't understand some things here and there.
Alright, so for a project (a sensor hub) I bought an Wemos D1 R2 and a few sensors. The problem is, I cannot get any of my sensors to work which use I2C. One of the I2C sensors I wanted to uses is the GY-BMP280-3.3.
I wired it up in the following way: VCC -> 3v3 GND -> GND SCL -> D1 SDA -> D2
So the SCL and SDA wires are both connected to the VCC line with a 10kOhm resistor.
Note that I use a non-arduino board, so the pinouts are a little different, but the D1 and D2 pins should be the correct pins according to the Wemos D1 R2 pinout: In my wiring I used the bottom right D1 and D2.
I then used a esp8266 I2C scanner to see if I could detect the sensor, but he can't find/detect it. It keeps saying: "No I2C devices found"
So does anyone see something which could be wrong with the code, wiring, or sensor + board combination. Or has anyone some tests to maybe figure out what could be wrong?
