I use the Nucleo-H743ZI to connect to an SDIO card. The IDMA done interrupt work well, and the code runs into 'SDMMC1_IRQHandler()' as expected.But after enabling the 'SDMMC_IT_SDIOIT' using:__SDMMC_ENABLE_IT(SDMMC1, SDMMC_IT_SDIOIT);And I measured t...
I want to use scanf function for usart with dma please help me for that.I need to receive a string through scanf but the string size will differ each time .
I viewed this question earlier.The Github link provided in answer to the question is of a project which seems to be no longer maintained and seems to be obsolete. I have built and run the project on my Android device and faced some reliability issues...
Hi, im flashing code autogenerated with STM32CUBEMX and using STM32IDE trough an stlink(from a nucleo-F303RE).The problem: after flashing/debugging the SW pins are left unusable? because i cannot reflash or access the board again unless i manually pu...
The minimum requirments of rising edge include but not limited to voltage, lasting time of high level, input current or charge and so on.
Something along the lines of: ./configure CFLAGS="-O2 -mfpu=neon -mthumb -mcpu=cortex-m4" LDFLAGS="--specs=nosys.specs" --host=arm-none-eabi --disable-rtcd --enable-fixed-pointStill having issues with make errors, e.g., celt_pitch_xcorr_arm-gnu.S:54...
Hello,I know it sounds like a basic and dumb question but I actually didn't find the answer.I have communication issues between 2 STM32H743 based Nucleos.On the master I use SPI1.If I use SPI1 on the Slave it works fine (repeated send/receive communi...
Hello community,I have a strange behaviour with my timer. Well probably it is not strange but the problem sits between keyboard and mouse, but hopefully you can help me find the cause.following the setup of my program:I use STM32F4 on a self-created ...
Hi,I have a school projet about preventive maintenance on WC. Due to the COVID-19, we no longer have access to the material, but we have to try to continue the project.We use a turbine which is connected to the water access (in the WC) and it will be...
Hi,I'm working on a custom board based on STM32L486 MCU, the microcontroller will stay most of the time in standby and will wake up using a physical button connected to SYS_WKUP3. This to say that the overall board consumption have to be as low as po...
