Expand description
The 16-bit command words, sent most-significant byte first.
Each word already carries the part’s 3-bit command checksum, so it is written as two bytes with nothing appended.
Constants§
- BREAK
- Stops periodic acquisition, aborting any measurement in progress, and returns the part to single-shot mode within 1 ms.
- CLEAR_
STATUS - Clears the alert-pending, tracking-alert, and reset-detected flags.
- FETCH_
DATA - Reads the latest periodic-mode data pair; the read is NACKed if none is ready, and the data memory is cleared once it is fetched.
- GENERAL_
CALL_ RESET - The I2C general-call reset: address byte 0x00 followed by 0x06. It resets every device on the bus that honours the general call, not just this part.
- HEATER_
DISABLE - Switches the heater off, which is its state after any reset.
- HEATER_
ENABLE - Switches the plausibility-check heater on.
- PERIODIC_
0_ 5_ MPS_ HIGH - Periodic, 0.5 measurements per second, high repeatability.
- PERIODIC_
0_ 5_ MPS_ LOW - Periodic, 0.5 measurements per second, low repeatability.
- PERIODIC_
0_ 5_ MPS_ MEDIUM - Periodic, 0.5 measurements per second, medium repeatability.
- PERIODIC_
1_ MPS_ HIGH - Periodic, 1 measurement per second, high repeatability.
- PERIODIC_
1_ MPS_ LOW - Periodic, 1 measurement per second, low repeatability.
- PERIODIC_
1_ MPS_ MEDIUM - Periodic, 1 measurement per second, medium repeatability.
- PERIODIC_
2_ MPS_ HIGH - Periodic, 2 measurements per second, high repeatability.
- PERIODIC_
2_ MPS_ LOW - Periodic, 2 measurements per second, low repeatability.
- PERIODIC_
2_ MPS_ MEDIUM - Periodic, 2 measurements per second, medium repeatability.
- PERIODIC_
4_ MPS_ HIGH - Periodic, 4 measurements per second, high repeatability.
- PERIODIC_
4_ MPS_ LOW - Periodic, 4 measurements per second, low repeatability.
- PERIODIC_
4_ MPS_ MEDIUM - Periodic, 4 measurements per second, medium repeatability.
- PERIODIC_
10_ MPS_ HIGH - Periodic, 10 measurements per second, high repeatability. Self-heating can occur at this rate.
- PERIODIC_
10_ MPS_ LOW - Periodic, 10 measurements per second, low repeatability.
- PERIODIC_
10_ MPS_ MEDIUM - Periodic, 10 measurements per second, medium repeatability.
- PERIODIC_
ART - Periodic acquisition with the accelerated response time (ART) feature, which samples at 4 Hz.
- READ_
STATUS - Reads the status register as one CRC-protected word.
- SINGLE_
SHOT_ HIGH - Single shot, high repeatability, clock stretching disabled.
- SINGLE_
SHOT_ HIGH_ STRETCH - Single shot, high repeatability, clock stretching enabled.
- SINGLE_
SHOT_ LOW - Single shot, low repeatability, clock stretching disabled.
- SINGLE_
SHOT_ LOW_ STRETCH - Single shot, low repeatability, clock stretching enabled.
- SINGLE_
SHOT_ MEDIUM - Single shot, medium repeatability, clock stretching disabled.
- SINGLE_
SHOT_ MEDIUM_ STRETCH - Single shot, medium repeatability, clock stretching enabled.
- SOFT_
RESET - Resets the system controller and reloads the calibration data without removing power; the part is idle again within 1.5 ms.
