A magnetometer can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. I've initiated the i2c, sent the configuration bits to REGA, REGB and REGMR (Mode Register) and sent it back via USB connection with HAL_I2C_MEM_READ. I2C, or Inter-integrated Circuit, is a communications protocol common in microcontroller-based systems, particularly for interfacing with sensors, memory devices and liquid crystal displays.Similar to SPI, it's a synchronous protocol because it uses a clock line.The I2C protocol, however, uses less pins and is a much more robust standard. I2C is a 7 bit address and the last bit determines if the operation is a read or write operation. (it is more likely you have this chip).
