... Mobile Phones, Netbooks, Consumer Electronics, Auto Navigation Systems, and Personal Navigation Devices. The HMC5883L utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over other magnetic sensor technologies. These anisotropic, directional sensors feature precision in-axis sensitivity and linearity. These sensors’ solid-state construction with very low cross-axis sensitivity is designed to measure both the direction and the magnitude of Earth’ ...

... HMC5883L configurations. This prevents drawing down the supply voltage (VDD). MODES OF OPERATION This device has several operating modes whose primary purpose is power management and is controlled by the Mode Register. This section describes these modes. Continuous-Measurement Mode During continuous-measurement mode, the device continuously makes measurements, at user selectable rate, and places measured data in data output registers. Data can be re-read from the data output registers if necessary ...

... HMC5883L REGISTERS This device is controlled and configured via a number of on-chip registers, which are described in this section. In the following descriptions, set implies a logic 1, and reset or clear implies a logic 0, unless stated otherwise. Register List The table below lists the registers and their access. All address locations are 8 bits. ...

... HMC5883L Configuration Register A The configuration register is used to configure the device for setting the data output rate and measurement configuration. CRA0 through CRA7 indicate bit locations, with CRA denoting the bits that are in the configuration register. CRA7 denotes the first bit of the data stream. The number in parenthesis indicates the default value of that bit. ...

... HMC5883L Configuration Register B The configuration register B for setting the device gain. CRB0 through CRB7 indicate bit locations, with CRB denoting the bits that are in the configuration register. CRB7 denotes the first bit of the data stream. The number in parenthesis indicates the default value of that bit. ...

... HMC5883L Data Output X Registers A and B The data output X registers are two 8-bit registers, data output register A and data output register B. These registers store the measurement result from channel X. Data output X register A contains the MSB from the measurement result, and data output X register B contains the LSB from the measurement result. The value stored in these two registers is a 16-bit value in 2’ ...

... HMC5883L DZRA7 DZRA6 (0) (0) DZRB7 DZRB6 (0) (0) Data Output Register Operation When one or more of the output registers are read, new data cannot be placed in any of the output data registers until all six data output registers are read. This requirement also impacts DRDY and RDY, which cannot be cleared until new data is placed in all the output registers ...

... The format of the data bytes (payload) shall be case sensitive ASCII characters or binary data to the HMC5883L slave, and binary data returned. Negative binary values will be in two’s complement form. The default (factory) HMC5883L 8-bit slave address is 0x3C for write operations, or 0x3D for read operations. ...

... OPERATIONAL EXAMPLES The HMC5883L has a fairly quick stabilization time from no voltage to stable and ready for data retrieval. The nominal 6 milli-seconds with the factory default single measurement mode means that the six bytes of magnetic data registers (DXRA, DXRB, DZRA, DZRB, DYRA, and DYRB) are filled with a valid first measurement ...
