STM32F40 Pin Alternative function PG
Hello, I have a question regarding PG pins PG0 to PG10.Can any of these pins (PG0 to PG10) be used to provide a PWM signal at around 20kHz. Thank you in advance

LSI Clock is very unsteady and cannot be reset in software
Hi,I stumbled across a problem with the LSI when i realized, that my IWDG was about 20% faster than it should be.The clock is behaving very irregularly, this is more than the deviation in the datasheet. I read out the LSI from PA2 with an oscilloscop...
Resolved! STM32H5 HASH peripheral chunk sizes
I'm trying to use the STM32H563 HASH peripheral to speed up sha256 calculations.The examples all use HAL_HASH_Start() to write the entire message at once.However, I'd like to feed chunks of data to the peripheral. The OEMiROT mbedtls sha256_alt drive...
Error in initializing ST-LINK device. Reason: No device found on target
Hello i encountered this error on F072 nucleo board, it was working fine yesterday and todayit couldnt connect up to STM IDE, whats coursing this and how to overcome this issue?Error in initializing ST-LINK device. Reason: No device found on target
Resolved! How to tell if interrupts are enabled
I need to determine if the interrupts are enabled at one point of my code but I have not been able to find any reference for the STM32G474. It doesn't look like there is a PRIMASK register which is mentions in another post.I know how do enable and d...
So clock output on MDF CKI1
I am trying to provide a clock to PDM microphones using the CKI1 MDF pin, and no clock is being generated. The MDF correctly generates a clock signal on MDF CKI0. The IO configuration for CKI0 and CKI1 is the same (except for the alternate function r...
Bootloader OTA stm32l072
The micro STM32L072kz supports the OTA (Over-The-Air) method, I would like to perform the bootloader through the main firmware, without the need to use a USB cable or bus, write a firmware that with the help of a 4G modem downloads a new firmware fro...
Resolved! Vcore voltage levels - published values in source?
Hi,What are the Vcore volage levels for the STM32H562 as applied by the VOS configuration bits? Datasheet -VOS0-3 = [1.35, 1.20, 1.10, 1.00] VSource - VOS0-3 = [1.2, 1.1, 1.0, 0.9] V The discrepancy lies in some outdated comments I think; maybe the v...
N DMA Transfers based on a timer trigger
I'm trying to use timer 8, stm32f429I, as advanced timer, to do N DMA transfers, that copies data from portD to memory and it does trigger on PC6 after triggering, an N DMA transfers should be shot I have tried, but now it triggers only DMA transfer,...
Resolved! Interrupt for Output Compare no Output does not trigger - Need diagnostics
I have TIM20 configured in reset mode with CH1 as the trigger. I want an interrupt to run if the counter reaches a certain value. I’m using CubeIDE with CH2 configured with Output Compare no Output and the pulse duration set to the desired compare va...
