Oh,my god ! please help me !1.At present, the chip can read and write internal Flash, but after FATFS is mounted, the file cannot be opened.2.After f_open, the return value is FR_NO_FILESYSTEM.
I'm using a Timer (TIM8) in a capture compare application for measuring timing between signals. In some cases I don't need the value so I have been skipping the read of the CCRx register. I'm using a HAL command as the code below shows:The HAL_TIM_R...
I Am using STM32F303CB.I want to read the VBATT voltage from ADC1_IN17 as VBATT is connected to ADC1 channel 17.Here my Code:void ADC1_Init(){ RCC->CFGR2 |= RCC_CFGR2_ADCPRE12_DIV1; RCC->AHBENR |= RCC_AHBENR_ADC12EN; RCC->AHBENR |= RCC_AHBENR_G...
I am using nucleo-f446re board. It was running perfect before but suddenly i am getting USB device not recognized when I plug in my board to my system. And in device manager it is showing device descriptor request failed. Please suggest me the soluti...
Hi,I am porting an application from the STMF429ZI to the STMH753ZI and have noticed that the STMH753 is slower when reading the GPIO inputs compared to the STMF429. In one function, multiple GPIOs are read to gather 16 input states. Measuring this fu...
Hello Community,I am using STM32H745 controller in one of my project.I am trying to send data from M4 core to M7 core using SRAM. To test the same I am increment a variable and writing to 0x10040004 location from M4 and reading the same location (als...
Hi,I am planning to implement DALI on STM32G MCU, I have looked at the documentation but all the example projects are with STM32L1 or STM32F1 and the library provided by STM is based on IAR workbench. My questions are Can I implement DALI Slave on ST...
I am troubling to write and read data from external SDRAM & NOR Flash in our custom made hardware which has STM32F429 controller.Thread is disconnecting while debugging & writing & reading operation not succeed.Can you please explain the all steps in...
Hi everyone,I expected to get a faster multiplication processing using the arm_mult_f32 function than a normal multiplication like val1*val2. However, when I tested it using the SysTick->VAL I get a bigger processing time for the arm_mult_f32 functio...
