> Version 1: REFCTL0 = REFVSEL_3 + REFON; // 2.5V ref active This appears to turn off REFMSTR, i.e. neither reference is active for the ADC12. I don't see anything obvious in Version 2.

Hi friends, Is there any ULP Case Study for MSP430F5529 likewise MSP430FR5969 .If anyone had please share with me. Thanks in advance Beeresh
View ArticleForum Post: RE: MSP430F5341 A/D 2.5V reference
I replaced the first line with this REFCTL0 = REFVSEL_3 + REFON + REFMSTR; // 2.5V ref active and it now works the same as version 2 - the A/D counts bounce around a lot. Still a mystery. Appreciate...

The MSP's voltage is 3.3V, so the UART's voltage levels are 3.3V as well. The 5V on the board is the USB voltage before the voltage regulator that can be used for other things if needed. Dennis
