I am using a BME280 sensor with STM32L476RG microcontroler.
I am having trouble with the bme280_init() function.
In this function, I pass the first null_ptr_check() so dev , dev->read , dev->write and dev->delay_us are different from NULL.
But just after that when I enter the bme280_get_regs() function, I don't pass the null_ptr_check() whereas my device structure has not changed.
I investigated the matter with a debugger and I found out dev->intf_ptr has changed from BME280_SPI_INTF to BME280_I2C_INT, which I don't understand as there was no redefinition of the device structure.
Could someone help me?
