Hi everyone.we had performed a project with discovery f746 board that within it there just was a GUI task to run emwin functions.Another functions(such as reading and writing in sd card by fatfs , usb, spi and stuff) were placed in the routines of Bu...
When I write the value in loopeg. VALUE_to_WRITE = 1000;for(int i =0; i < VALUE_to_WRITE; i++){ HAL_DAC_SetValue(&hdac, DAC_CHANNEL_1, DAC_ALIGN_12B_L, value); HAL_DELAY(4);}//no less than thisThe value is written. But it const me 5-10 seconds wh...
Hello,I am trying to test my SD card with fatfs by the code generated from CubeMX. I used the library of STM32Cube FW_F4 V1.21.0The code waits SD_TIMEOUT (30sec) and then goes to error_handler.The below example works without a problem.STM32Cube\Repos...
Posted on February 28, 2018 at 12:19Hi,I've been playing around with FatFs for about 1 mounth now. I succefully used SDMMC and SPI protocol to save and read data from an SD card.I order to improve the system (it's a improvement for the project) We d...

void TIM5_IRQHandler(void) { /* USER CODE BEGIN TIM5_IRQn 0 */ printTIM5 = 1; //checks in main loop if set, then resets to zero and prints if(__HAL_TIM_GET_ITSTATUS(&htim5, TIM_IT_UPDATE)) { __HAL_TIM_CLEAR_IT(&htim5, TIM_IT_UPDATE); if(c...
I'm transmitting 1 byte of data via HAL_UART_Transmit_IT(). After this byte is being fed to the UART HAL via the abovementioned method, the HAL_UART_TxCpltCallback() callback is being fired (which is completely normal). The problem comes during the c...
I am not able to receive data using receive DMA NORMAL mode in a particular task.while Transmit DMA works perfectly. I am using STM32F103ZET6 , USART1. Working with FREE RTOS CUBEMx.Please help me with this.
Posted on October 18, 2017 at 08:30Hi All,Why there are no standard libraries for the STM32L0XX family?Building a new project for STM32L0XX depend only on HAL / LL ??link to ST standard libraries download page :http://www.st.com/en/embedded-softwar...
NUCLEO board can use ST-LINK by dividing it.Therefore, I use the ST-LINK part of the NUCLEO-767ZI and NUCLEO-207ZG boards in a divide.After the divide, the power part and the SWD part are connected normally.On the 207 board, Ethernet works normally b...
