Platform: STM32F429 Discovery KitI have created a simple project using Keil, to toggle GPIOs. The self generated code sets the clock at 168MHz. When I look at the timing for the SysTick_Handler call, it is 3ms instead of the 1ms that I expected. Why...
I work with stm32f405vgt, voltage 3.3 V, Cube MX ( version 4.27, HAL library - STM32Cube FW_F4 V1.21.0), sdio sd 4 bit widebus, fatfs, without dma, All CLK 18 MHz. I can’t mount the disk, open the file and write to the file. Attached is a schematic ...
Hi team,i need your help, i use STM32L011F4 controller ,This controller consuming 2mA current in sleep mode, as per datasheet it consumes only a less than 0.5mA current in sleep mode, i can use only a I2C and RTC peripheral with 16MHz frequency.......
Hi allI am new learner for use the STLink V2 programmer.I'm detect the error "cannot connect to the target" unable program to my MCU.I use my JTAG 20 pins connector and use few pin NRST,VCC,GND,SWDIO,SWCLK connect to my UUT connector .And also power ...
Hello,I would like to send a uint32_t size array via HAL_SPI_Transmit / HAL_SPI_Transmit_DMA but both are limited to 16 bit size. I have tried casting as HAL_SPI_Transmit(&hspi1,Array,(uint16_t)65537),10000)but this doesn't work.I have also tried edi...
How do I import a Cube project? I once managed to set up a project where I am able to write firmware for the stm32f746g-disco board using the tutorial https://www.carminenoviello.com/2015/07/13/started-stm32f746g-disco/ Even after the instructions I ...
Hello,I have just got a new board that I purchased using the STM32F030F4P6 MCU.This is a Mini Developing board that you can get from Ali Express and it is good as well IMHO.The Board that I have is:And I am bit struggling to make it to work under Ard...
Hi All; I would like to measure active power. DataTx[0] = 0xFF; DataTx[1] = 0x00; DataTx[2] = 0xA0; DataTx[3] = 0x00; DataTx[4] = Metro_HAL_CalcCRC8(DataTx); HAL_SPI_TransmitReceive(&hspi1, (uint8_t *)DataTx, (uint8_t *)DataRx, sizeof(DataTx),10...
