Is it possible to compare compare the output using STM32's timer interrupts

I am currently learning to use timer interrupts using the HAL library on the STMF769I-DISCO. I am trying to get the interrupt to activate when it reaches a certain value. From my understanding, the interrupt activates when the counter period overflow...

Troubles with flash programming on STM32G474RE. Can`t write anything to bank 2.

Hi everyone, i`ve got trouble with InApp flash programming on STM32G474RE. While i`am trying to load some data to address higher than 0x08040000 (Bank 2) in dual bank mode by the internal bootloader (placed on address range from 0x08000000 to 0x08005...

stm32g071 HAL_I2C_Slave_Seq_Transmit_DMA DMA TC flag is set even if one element less than requested was transferred

I am using a stm32g071 as an I2C slave.Problem is, that I2C_SlaveTxCpltCallback() callback is called even when the master read one byte less than previously configured.I.e. With RXSIZE = 4 (as in code below),if master reads 1 byte -> okif master read...

Why is my buffer corrupted when for-loop is split up?

Hello,I have a project on a Nucleo board that samples the ADC and typecasts the result.The typecasted value and the original value are sent via UART and virtual com to my PC.When I put this code in a single for-loop, I can receive both the raw and co...

STM32H7 - external SDRAM on FMC - optimal configuration for code execution

We have a STM32H745 MCU, an IS45S16320F SDRAM on the FMC interface, which is used for a Codesys application code execution.This is the SDRAM init:/** Perform the SDRAM1 memory initialization sequence */ hsdram1.Instance = FMC_SDRAM_DEVICE; /* hsd...

How to set SDA line of I2C low using software

I'm using LC709203F to measure RSOC. It is going to sleep mode after 1.2 Ms.To wake up from sleep mode , I have write 0x0001 to register 0x15 in fuel gauge.Prior to that , I have to set SDA line to low for particular time.Please help me to set SDA li...

STM32L562VET6Q : Inside HAL_SD_Init, SDMMC_ConfigData() does not configure DTIMER and DLEN. So the function SD_SendSDStatus always returns a timeout error (errorcode = 8)

UART debugging

I setup my custom board with STM32F401RE. I am using the HSI a the moment with configuration shown in the image below. All I am doing is printing some lines using this function on the UART2:#ifdef __GNUC__ /* With GCC, small printf (option LD Linke...
