Announcing the Hall Magnetic Camera HMC9076

The Hall Magnetic Camera HMC9076 is a platform for building semi-custom magnetic-field mappingThe process of measuring magnetic field intensity at many different points, in order to understand the structure of the field... systems.

The key system features are:
- Multiple Hall sensors provide high-precision, simultaneous 3-axis field measurements at multiple points.
- USB provides both system power and data communication.
- An optional thermal sensor allows for temperature compensationHall magnetometers are sensitive to temperature, so they may include a temperature sensor that allows the instrument to compensate the... or regulationA NMR-regulated magnet is an electromagnet whose field is measured by an NMR teslameter, which then closes the loop by....
- An optional low-noise voltage regulator provides optimal measurement stability.

The platform consists of:

Hardware:
- Magnetic field sensors: MagVectorTM MV2
- Microprocessor: Silicon Labs C8051F380
- Voltage regulator: Texas Instruments REG102
- Temperature sensor: Texas Instruments LM71CIMF

Firmware:
- Write and read SPI data to/from selected device
- Synchronise acquisitions
- Loop-back test of USB communication
- Retrieve hardware/firmware versions
- Get device information
- Read or write arbitrary data, e.g. calibrationDuring calibration, the instrument reading is compared to one or more references to verify its accuracy. The references themselves need... tables, to ROM

Software:
- LabVIEW API to access all firmware features
- MagVector MV2 register access
- Programming examples
