Is it possible to use the capture compare function to interrupt on an encoder value?

Based on the documentation it seems unlikely. However this also seems like an obvious use-case.Are there any examples doing this?Thanks

How do you design board support drivers?

I have got to implement a board support package for a custom board, and I would like to know your opinion about the different approaches of designing board support drivers. My custom board pupulates an STM32 microcontroller besides other components l...

RTC_HOURFORMAT_24 does not work in L053.

My environment is as follows:CubeMX v4.26.1 with STM32L0 HAL v1.10.0STM32L053C8Txgcc-arm-none-eabi-7-2017--q4-majorI set the RTC with RTC_HOURFORMAT_24. Actual code for the setup was generated by the CubeMX. If I set the clock to 12:59:59 then the R...

extern "C"

Hello everyone, maybe it's a stupid question but in the interrupt handling function I can't rewrite a variable. I'm sure that the interrupt is triggered and assigns a value to rx_counter, read_msg is executed in a loop, but when the value of a variab...

hello you guies.i am tring to erase my flash memory of STM32F767 Nucleo-144 board but i couldn't do that.That's because my STM32F767 Nucleo-144 board could not be operation right. As soon as i set STRT bit of Flash control register (FLASH_CR) but STM...

In the reference manual for STM32H7 interrupt with NVIC position 123 is missing. What is the interrupt?

Reference manual for STM32H7 series (RM0433), on page 697, does not show an entry for NVIC interrupt 123. What is the interrupt? Can the documentation be fixed by the team.Interrupts that are not triggered by the MCU are normally marked with a line a...

CAN_Networking code sample

I found CAN_Networking code sample in STM32Cube repository: STM32Cube\Repository\STM32Cube_FW_F4_V1.21.0\Projects\STM324x9I_EVAL\Examples\CAN\CAN_Networking. It doesn't run directly on my STM32469I-EVAL board. I have two questions:What is STM324x9I_E...

STM32F427 internal RAM for code, external SRAM for dynamically alocation memory (heap) - how it get ?

Hi, I have a project based on STM32F427IGH with external SRAM AS6C6416 (64M). for some functions I need a lot of memory, for another -fast access, as the SRAM not fast (50 nSec) I would like to use it only for dynamically allocation memory. After all...

DFU mode -- Can it be entered with power on?

When I put 3.3V to boot0 and 0V to boot1 and then 0V to NRST,I don't get DFU mode. I have to cycle power withboot0 HI to the MCU to get DFU mode.The docs suggest different. have I misinterpreted the docs?Thanks, John
