Why the maximum value of Tim4Encoder is 127 rather than 32767?
int16_t GetTim4Encoder(){ Tim4Encoder = __HAL_TIM_GET_COUNTER(&htim4); //__HAL_TIM_SET_COUNTER(&htim4,0); return Tim4Encoder; }

DMA stop working after a sucessful receiving data USART.
In a noisy media, I need to receive 10bytes with DMA (about 1Mb). I have set the DMA and its interrupt as shown below:void DMA_Configuration(void) { DMA_InitTypeDef DMA_InitStructure; RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE); ...
How to building a custom external loader for a custom board based on a STM32F4 MCU?
Hi, community:I'm working on a custom board based on a STM32F7 MCU,which I have use the MCU is STM32F750Z8T6 and spi flash is W25Q064AJVSSIQT(Winbond).But the assets (images, font ...) are too large to be loaded into the memory of the MCU and have to...

Hi everyone!i have an issue with communication! As shown below, when I press the green button I want to toggle led on the IoT board & when it’s the red I want to toggle WiFi ble led( I didn’t find an other user led)if i press the red button it works ...
The STM32F303RBT6 ADC2_IN3 data is abnormal when the pin PC4 set high.
The STM32F303RBT6 ADC2_IN3(PIN PA6) is connect to GND .When the pin PC4 set high,the ADC_IN3 read a abnormal data 0x70. When the pin PC4 set low,the ADC_IN3 read a normal data 0x00. Which the PC4 set high,is affect theADC2_IN3 sa...
new STM32H7B3 and SRAM quantities
Hello,I have a doubt about the amount of SRAM available on the STM32H7B3.In the datasheet it is indicated 1184kB (setion embedded SRAM), but the linker script indicates 1024kB.In the datasheet, there is not much detail on this.My goal is to use for a...
STM32 L031K6 Multi channel ADC
Hello. I am looking a way to read values from multiple channels of ADC module of a L031K6 MCU. Following an example in youtube I tried to use interrupt method. In the video he uses a F051R8Tx MCU. I develop code in STM32CubeIDE and tried the same ADC...
STM32F7xx interrupt trigger timer counter reset
Is there a way to reset the timer (TIM4,3) via interrupt pin without using the interrupt handler/vector table?
