Dear Team,
Is there any specific procedure to programming the TMP75? At present we have encountered a problem in the test, that is, when the software is doing the foot pin test of the OS, to modify the internal register of the TMP75, first set the temperature point for the Alert to trigger.
However, sometimes it takes two or three times to write Alert to react. What I want to know is, is there a certain program in the order of writing or is it only necessary to set the temperature point to trigger Alert?
At present, TMP75 is known to have only 4 register registers, which are 0x0~0x3, and 0x0 is the current temperature value of Senser, 0x1 is Config, 0x2 is Alert low temperature set point, and 0x3 is Alert high temperature set point.
Alert Trigger Low Setting:
# write the register 0x2, value 0xD800
# write the register 0x3, value 0xE200
Alert Trigger High Setting:
# write the register 0x2, value 0x6900
# write the register 0x3, value 0x6E00
