Resolved! STM32 boot mode

Hi,I'm currently working with the STM32G491RET and using the NUCLEO-G491RE evaluation board. I need to check whether the device enters boot mode using the BOOT0 pin and NRST. From my understanding, to enter boot mode, BOOT0 should be driven low, and ...

Occasional jumps during TSC reading

I am working on touch detection with STM32L412cbt6 MCU. I am reading from two channels via G1 of TSC and it is working fine. However, when I look at the other group (i.e. G2), there are fluctuations in both channels from time to time but these values...

Resolved! STM32H745i-disco uboot support or device tree

Hi,I'm curently working on a STM32H745i-disco and need to implement a uboot on it. It doesn't seem to be natively supported. I would like to know if there is a port on going or at least if you have somewhere the linux/uboot device tree for this board...

STM32H562 Digital vs Analog temperature sensor

HiWe are currently working on a new board with a STM32H562. As part of the design, we want to measure the temperature of the MCU. In the Datasheet of the STM32H562 I see the “Analog temperature sensor” (as I know it from other STM32) connected to the...

Resolved! First call of timer expires immediately

Hi,I am trying to check if a button is pressed for 3s continuously using a timer which is started through an interrupt. The code for the same is attached below. The issue I am facing is the interrupt is immediately called when I press the button afte...

Resolved! Unusual high and nonlinear ADC offset

Hello everyone,I've been struggling with the ADC of a STM32G474QE on a custom board for some while now. I initially saw a discrepancy between an onboard NTC thermocouple and its measured ADC value. The measured Value (calculated to mV) was off by an ...

Resolved! CAN Communication Issue

Hi, I am using STM32F446RE Nucleo and a Peak CAN Usb to test the CAN functionality of the microcontroller. I have connected the Microcontroller to a CAN Transceiver (TJA1050) and added a 120ohm resistor between the CANH and CANL line. I have attached...

Resolved! 5V FT pins vs. injection current on STM32G0

I am confused about the limits of the FT pins on this MCU. I think I understand the maximum voltage on an FT pin except FT_c is Vdd + 4V as long as no pulls are enabled. So with 3.3V Vdd the max voltage on most FT pins will be 8.3V is that correct? I...
