BMP180 start problem


#1

I tried the example of BMP180 (get_temp_pres_alt) on WeMos D1 Mini board and the connection as below:

I2C0:

BMP180 (Vin) -> Wemod D1 Mini (3.3V)
BMP180 (GND) -> Wemod D1 Mini (GND)
BMP180 (SCL) -> Wemod D1 Mini (D1 (SCL) board label) or D2 Zerynth pinmap
BMP180 (SDA) -> Wemod D1 Mini (D2 (SDA)board label) or D3 Zerynth pinmap

I tried both cases, with pull-up resistors (10K) and without pull-up resistor.

In both cases I also got the same error messages as below:


[HardwareInitializationError @[001C:001B:0025:002C:0000:0020:0000:0000]](javascript:window.except(’@[001C:001B:0025:002C:0000:0020:0000:0000]’,'HardwareInitializationError '))

start…

[Thread 1 exited with exception HardwareInitializationError @[001C:001B:0000:0034:0000:0000:0000:0000]](javascript:window.except(’@[001C:001B:0000:0034:0000:0000:0000:0000]’,'Thread 1 exited with exception HardwareInitializationError '))
