STOP2 Mode in stm32u5g7
Hi I am utilizing an STM32U5G7 microcontroller to operate a BLDC motor with a system clock frequency of 80 MHz. I require assistance in configuring the device to enter and exit Stop2 mode to achieve the lowest power using the RTC wakeup functionality...
Clock Gating (I2C HSI kernel clock) prevents Standby
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...
STM32H523CET6 Debugging stops when calling HAL_InitTick()
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...
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 ...
