STML011 temperature sensor accuracy
Hi,I am having problems measuring accurate temperatures with the internal temperature sensor of the STM32L011D4P7 over the full device temperature range of -40 °C to 130 °C.What I did: Measuring the temperature as described in the Reference Manual (R...
How to implement RFU/OTA to STM32L496?
Hello,So I want to add RFU or OTA to my code as a feature. I saw an rfu source code to one of the expansion of STM32, however it is disabled. I tried to enable it by defining RFU but somehow there are missing files such as se_def.h and se_interface.h...
How to read push button long press and short press using timer and counter ?
Hi, I am new to this STM32 development. I am using STM32F051R8Tx board and STM32CubeIDE. I want to read the push button for long press and short press how to do this?
unable to debugg Hardfault error on STM32F412ZG
Hello community,I am trying to write time critical code which involves an STM32f412ZG Nucleo 144 board and a RPi communicating over SPI protocol. I have an IMU sensor communicating to STM32 board via I2C interface. I have 3 tasks, which function as ...
IWDG and CPU Registers
I am working on STM32H7 (Cortex-M7) and using IWDG for monitoring. I am wondering if there is a way to record Cortex-M7 CPU registers (General Purpose (Rx), SP, LR and PC) when IWDG runs out. Either before or after the reset.I understand the RCC regi...

Best method for returning to STOP Mode after Interrupt (STM32L0)
Hello,So I have a project which uses STOP mode with RTC+EINT pins for wakeup. However I have a situation where I want one of the interrupts to not wake up the device- just set a flag and return to STOP mode. I know there is HAL_PWR_EnableSleepOnExit(...
