i have successfully make some basic module in stm32l552 nucleo in register level and in asm , successfully programGPIO, TIMER, UART RX,TX,. But stuck in interrupt section for few days. i am tring to toggle onboard led(PA9) using user button PC13. my ...
I want to check and ensure the option bytes are correct from with my executing program. But writing the option bytes is very flaky if the IWDG is active. For some reason, there is a stall at "FLASH_CR_OBL_LAUNCH". Or maybe it makes it past but not so...
Hello STM Community,I am currently working with the STM32C031C6 Nucleo board to implement various power reduction techniques, including Sleep, Stop, and Standby modes. At this stage, I am trying to wake the MCU from STOP mode using the RTC wakeup tim...
Hello there!I am on my first foray away from HAL and into bare-metal programming, and am trying to configure LPTIM1 and LPTIM2 on my stm32u031 to periodically trigger interrupts. I am experiencing bizarre behavior that I'm struggling to understand ho...
Hi,I encountered a behavior contrary to Reference Manual while erasing FLASH page on STM32G473xB (128 KiB of FLASH memory).The scenario is that I use several pages at the end of FLASH for classic eeprom emulation, so there are flips between two halve...
Dear community,In STM32G0 or maybe in STM32 family in general, is there a possibility to disable the debug module permanently, the idea is that when the code is loaded and tested, then the next step is to disable SWD/JTAG port so that debug or loadin...
Hello, I am designing a device that will have an STM32L4 or maybe an STM32U and will communicate with an ESP32 for internet connectivity. However, at some point, I would like to update the firmware remotely, and have the ESP32 stop executing its conv...
Hi everyone, I’m working on a project involving STM32L476 chip, and I’d appreciate your guidance on a few key points:Out-of-box USB flashingI'll soon have a brand-new STM32 chip that hasn’t been flashed yet, is it possible to use STM32CubeProgrammer ...
Hello, I am quite new to this. I am generating a PWM signal(100Hz with 40% duty cycle) using Tim1 on my stm32f103c8t6(Bluepill). I want to take ADC readings(both ADC1 and ADC2 in simultaneous mode) during the high part of the PWM signal at a frequenc...
I have developed code (on the NUCLEO-L433RC-P) that uses shutdown and wake.The code works when I debug or run, but it stops working after a cold restart (power removed then reconnected).After a cold restart, the software runs correctly until the firs...
