Hi,I have a situation which I would like to understand better:I have an STM32U595ZJT6Q with I2C2 configured to use HSI16 (not PCLK1) as its kernel clock. I put the STM32 into Standby to save power.Recently I implemented Clock Gating to save power whe...
Hello!I have a problem when trying to debug in VSCode using Cortex Debug extension. The flashing process is working, but I cannot go further than HAL_Init. The exact problem is with the HAL_InitTick function, to be more precise, after the HAL_NVIC_En...
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 ...
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...
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...
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...
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...
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 ...
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...
HelloI am new to the STM32U5 and have problems with I2C communication via GPDMA.My transmit buffer consists out of ten messages that should be send.Strangely, only two write commands are written to the bus. However, this includes the first and the th...
