VEML6070 after v1.1.0 not recognized anymore
The I2C-communication with the VEML6070 does not work with the HTCC-AB01-board later than the version v1.0.0. When running the I2C-scanner, the VEML6070 does not show up.
However, all other connected sensors like the SI7021 and BMP280 are recognized successfully and can be read out using the sample-scripts.
It appears to be an issue in Wire.cpp or something similar, which has an impact in the communication to the VEML6070 in a change between V1.0.0 and V1.1.0.
Following tests were made:
Board | SW-Version | Sensor | Result |
---|---|---|---|
HTCC-AB01 | V1.0.0 | VEML6070 | Sensor shows up in I2C-scan and can be read out |
HTCC-AB01 | >=V1.1.0 | VEML6070 | No I2C-device found. Sample-script of VEML6070 reads 65535 (invalid) |
HTCC-AB01 | >=V1.1.0 | SI7021 | Sensor shows up in I2C-scan and can be read out |
Arduino Uno | - | VEML6070 | Sensor shows up in I2C-scan and can be read out |
