HMC5983
I2C OPERATIONAL EXAMPLES
The HMC5983 has a fairly quick stabilization time from no voltage to stable and ready for data retrieval. The nominal 56
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.
To change the measurement mode to continuous measurement mode, after the power-up time send the three bytes:
0x3C 0x02 0x00
This writes the 00 into the second register or mode register to switch from single to continuous measurement mode
setting. With the data rate at the factory default of 15Hz updates, a 67 milli-second typical delay should be allowed by the
I2C master before querying the HMC5983 data registers for new measurements. To clock out the new data, send:
0x3D, and clock out DXRA, DXRB, DZRA, DZRB, DYRA, and DYRB located in registers 3 through 8. The HMC5983 will
automatically re-point back to register 3 for the next 0x3D query. All six data registers must be read properly before new
data can be placed in any of these data registers.
Below is an example of a (power-on) initialization process for “ continuous-measurement mode ” via I2C interface:
1.
2.
3.
4.
5.
Write CRA (00) – send 0x3C 0x00 0x70 (8-average, 15 Hz default, normal measurement)
Write CRB (01) – send 0x3C 0x01 0xA0 (Gain=5, or any other desired gain)
Write Mode (02) – send 0x3C 0x02 0x00 (Continuous-measurement mode)
Wait 6 ms or monitor status register or DRDY hardware interrupt pin
Loop
Send 0x3D 0x06 (Read all 6 bytes. If gain is changed then this data set is using previous gain)
Convert three 16- bit 2’s compliment hex values to decimal values and assign to X, Z, Y, respectively.
Send 0x3C 0x03 (point to first data register 03)
Wait about 67 ms (if 15 Hz rate) or monitor status register or DRDY hardware interrupt pin
End_loop
Below is an example of a (power-on) initialization process for “ single-measurement mode ” via I2C interface:
1. Write CRA (00) – send 0x3C 0x00 0x70 (8-average, 15 Hz default or any other rate, normal measurement)
2. Write CRB (01) – send 0x3C 0x01 0xA0 (Gain=5, or any other desired gain)
3. For each measurement query:
Write Mode (02) – send 0x3C 0x02 0x01 (Single-measurement mode)
Wait 6 ms or monitor status register or DRDY hardware interrupt pin
Send 0x3D 0x06 (Read all 6 bytes. If gain is changed then this data set is using previous gain)
Convert three 16- bit 2’s compliment hex values to decimal values and assign to X, Z, Y, respectively.
