Hi, These after read this thread about how to use temperature calibration data, I tried to use TLV register to obtain the "real" voltage reference value and increase the ADC conversion by compensating the gain and offset. The test was performed in a Launchpad EXP430FR6989, but can be applied to other launchpads compatible with MSP430Ware driverlib. The increase in the accuracy is very interesting. in the table (sorry by the comma instead of point, brazilian notation). HP 3478A - value measured with DMM ADC_correct1 - value measured with MSP430 without any correction ADC_correct4 - with all corrections using float variables ADC_correct5 - using mainly integer Here there is an article about this test and the Github with the example.
