Helloi am using UART string command in switch to start stop adc DMA. Start, Stop command work fine only once but after stop command when i give start command ADC DMA does not start again.Belo both function ADC init(CUBEMX created) and ADC_StartStop(O...
Hi Everyone. I have a question relating to my project, and I think I have it tracked down to one problem area. As a hobbyist, I don’t get the time to work on my projects as someone working in the Industry does, and figuring it all out take so much lo...
I was not involved in ST MCUs (STM32F769 specifically) until now. I understood that CPU gets stack pointer at start, from address 0, but what there exists is RAM - which is undefined after power up. Then, how can I force some "reasonable" SP value in...
Hi, Im searching way to avarage two unsigned 32 integers.Is there any hardware help in doing this with stm?
Hello, I need advice. I am working on a device for revolution counting and need advice how to put the timer in the counter mode in operation with the stm32f103rb processor in order to count external pulse independently and I would like to have the re...
Hi,I am using HAL driver for STM32F4 microcontroller. Every thing is fine. But, I have the following compilation error for this macro (SDMMC_STATIC_FLAGS) from stm32f4xx_hal_mmc.c. This macro was not found in the header file also. How to resolve this...
Hello,I'm am using the STM32L4R9I-DISCOVERY board with external FLASH memory using OCTOSPI.I wan't to use it if possible in memory-mapped mode to read and write as a persistent storageAccording to the STM32L4+ documentation RM0432 (1) it is possible...
I have designed and produced circuits with the F4 and L4, using plain Eclipse for development and SEGGER J-Link for both development and the ICP fixtures at the line.I have not been successful at getting J-Link Commander to play well with a G431 over...
