6. COMMAND DESCRIPTIONS
(For commands specific to nano-resolution, please refer to Section 8.)
SAMPLING COMMANDS (may be used as global commands.)
P1
Sample and send one period measurement of the pressure signal in
microseconds.
ACTION: Start pressure count, read count when done, calculate period
using timebase and integration time, send reading, await
next command.
TYPICAL COMMAND: *0100P1
TYPICAL REPLY:
*000129.12345
P2
Continuously sample and send pressure signal periods.
ACTION: Start pressure count, read count when done, restart count,
calculate period using timebase and integration time, send
reading, read next count when available and loop until
stopped.
TYPICAL COMMAND: *0100P2
TYPICAL REPLY:
*000129.12345
*000129.12346
*000129.12344, etc.
P3
Sample and send one compensated pressure.
ACTION: Start temperature count, read count when done, start
pressure count, correct temperature count for timebase and
integration time, compute temperature compensated
pressure coefficients, read pressure count when done,
correct pressure count for timebase and integration time,
calculate pressure, send reading, await next command.
TYPICAL COMMAND: *0100P3
TYPICAL REPLY:
*0001555.444
