HTU21D sesnor with Nucleo-L152RE

Here is the IOC file. HAL_I2C_Init() is called in MX_I2C1_Init(), it is already present in code but unfortunate I forgot in snippet code.

Also attched HTU21D interfcae which is already present pull-ups on I2C lines.

Thanks for your exceptional support.

• Here I attached full interface snapshot of NUCLEO-L152RE with HTU21D sensor and main.c file. In the snap -shot you can find that there is pull-ups present on SDA and SCK line. So, can you please guide me how to solve this issue to read proper temperature data.
