Hello everybody,
TechRef SPRUHM8 refers to the funtion "DAC_tuneOffsetTrim", which is part of the C2000ware driverlib.
This function can be used to adjust the DACTRIM value if DAC is operating with a different ref than 2.5V .
My question:
After executing this function, is the new TRIM-value stored in the the TRIM-Register and the 2.5V-REF-TRIM-value is lost?
Or is the original 2.5V-REF-TRIM-value reloaded into the TRIM-Register after RESET?
Thanks in advance,
Jan
Hi Jan,
Yes, that is right, The original 2.5V trim is reloaded automatically by Devcal in Bootrom every time the device goes through a reset.
