Disable nterrupt inside the IRQ Handler allowed??

Hello,i disable the interuppt after its execution is it allowed?void EXTI4_IRQHandler(void) { // Clear interrupt __HAL_GPIO_EXTI_CLEAR_IT(SYNC_UC_PIN);   // call function function();// the function enables an other interrupt of the same pri...

STM32L010 FLASH_SR bit OPTVERR set when erasing a flash page

I am using an STM32L010k8 with HAL driver version 1.11.2, when I erase a single flash page at address 0x08004000, the very first call to function FLASH_WaitForLastOperation within HAL_FLASHEx_Erase fails because the OPTVERR bit in FLASH_SR register i...

OpenOCD failed : stm32f4x.cfg:77: Error: invalid subcommand "newtap stm32f412 cpu -irlen 4 -ircapture 0x1 -irmask 0xf -expected-id 0x4ba00477"

Hi experts,We have created a project on WICED 43xx_Wi-Fi sdk for STM32F412 MCU+43438 wlan chip.We have connected st-link V2 debugger to the EVB and we could see "STM32 STLink"​ in windows Device Manager.When we used openOCD to flash debugger to EVB, ...

STM32F769NI Evaluation board NEWBIE

Hi AllI am just starting off with the STM parts and bought the 469 EVM. I got the touch ID with TouchGFX working and made some cool things but now it is time to start using the periphials on the board in bare metal C config.I am really looking to do ...

How to program internal flash memory of STM32H745ZIQ Controller using HAL API?

I am having problem with program flash by 8 bits. How can i change the default bit settings to 8 bit.I am using the HAL_FLASH_Program api and i tries to set psize of bank 1 by __HAL_FLASH_SET_PSIZE(FLASH_PSIZE_BYTE,FLASH_BANK_1) api but no success. P...

How to extend trial period of Emnify SIM

Can I use the Quad SPI memory controller peripheral on STM32F4xx series to access a PSRAM or SRAM IC rather than a flash IC, and have the data memory map as if internal RAM?

I am hoping to use the CMSIS/DSP libraries to work on data that I periodically store on external RAM. If it is important, my current plan is to use the Lyontek LY68L6400 PSRAM or the VTI7064 SRAM (more expensive). Both are 64Mb volatile memory ICs th...

Implementing controlled phase shifted PWM on STM32F051R8T6 or STM32G030C8

I want to develop a full bridge converter, for which I need two PWM channels with complementary outputs. In order to turn off the load, I need to implement phase shift on one of the PWM channel and its pair(as shown in the image). I began by using ST...
