Board resetting - USB communication lost - NucleoL432

I recently had a problem with one STM NUCLEO32L432, it was resetting randomly after 4 to 5 min causing communication loss through USB port... From Gregory Hancock: "Disabling the 'MBED Microcontroller USB Device' under 'Disk drives' in Windows Device Manager seems to have solved the problem. Th...

How to enable OPAMP in NUCLEOL432KC?

Hi!

Does anyone know how to enable the OPAMP in the Nucleo32L432? I'm connecting a sensor to PA0 (OPAMP1_VINP), but, I'm not sure if the OPAMP is working or not.

Thanks

Re: ADC External Voltage Reference (AnalogReference)

I was having a hardware issue...
To enable the external Vref, just disable the SB10 and we should be fine... (Vref should always be < than VDD)

Re: ADC External Voltage Reference (AnalogReference)

Thanks GonzoG... I found the instructions in the manual, I deactivated the SB10 and provided a direct 3Voltage to pin Vref (pin13), and now I can have a full 10bit ADC count up to 1023... (I'm using a sensor with max output of 3V) Nevertheless, my sensor has an offset value of 400mV, I would expect ...

ADC External Voltage Reference (AnalogReference)

Hi, Is there a compatible command to set the external Vref through Pin 13 in the Nucleo 32 boards? I have tried to disable Jumper SB10 and then connect directly a Vref = 3V, but, this is not completely working... I'm looking for a compatible command like: AR_EXTERNAL as it is available for SAMD boar...

Re: STM32L432 serial monitor not working

Partial Solution:

I was using a wrong board configuration, I was using the board: "generic STM32L4 series", but I changed to "Nucleo32"...
Changing the configuration helps to get I/O from the serial monitor, but the board stops working randomly after some minutes...

STM32L432 serial monitor not working

Dear all, Problem: The serial monitor (Serial.read) is not responding to keyboard commands Code: char userInput; void setup() { pinMode(PB3, OUTPUT); Serial.begin(9600); // Baud Rate set to 115200 } void loop() { userInput = Serial.read(); if (userInput == 'y') { delay(5000); while (true) { digitalW...
