  1. Hello, I have MSP430FR6989 Launchpad. As per below schematic,I generate internal Vref+ voltage 1.2V on Pin P1.1. I'm successfully measure 1.19V on pin P1.1. So,This Vref I apply in NTC as per below schematic( please ignore MSP430FR4133). But I got an issue in below code: void Vref_ON() { while(REFCTL0 & REFGENBUSY); // If ref generator busy, WAIT REFCTL0 |= REFVSEL_0 + REFON + REFOUT; // Enable internal 1.2V reference while(!(REFCTL0 & REFGENRDY)); // Wait for reference generator // to settle } void Vref_Off() { REFCTL0=1; } void setup() { Vref_ON(); Serial.begin(9600); } void loop() { // int val = analogRead(A11); //**** When comment this portion then on P1.1 Vref+ get voltage (1.19V), uncomment then get voltage 0V **** Serial.println(val); delay(500); } In above code, pin P1.1 I got a 1.19V Vref+ successfully but I got an one issue on above code : Please mention comment in code. I can't understand above issue. Please give me a suggestion for issue. Thank you. Regards, Pratik
  2. Hi, I want to map the internal reference (2.5V) of the ADC to an output pin. It is possible as describe here (if I understand it correctly): http://forum.43oh.com/topic/5985-use-msp430g2553-internal-reference-voltage-at-an-output-pin/ But I was unable to find a way to do it in Energia. I found something interesting in the driverlib, but I have no idea how to use it. https://github.com/energia/Energia/blob/master/hardware/msp430/libraries/DriverLib/utility/ref_a.c Hopefully someone can point me in the right direction.
