I have an OPi zero 2 and a BMP180 i2c device. I can detect the BMP180 device by i2cdetect -y 3 which returns the correct 0x77 address. I also have wiringOP installed.

However, using the BMP180.c sample from https://www.waveshare.com/wiki/R ... es:_I2C_Programming gives a message:  Unable to open I2C device: No such file or directory
