Hii everyone,I'm using stm32f4 discovery board and its header board which consist sd card interface in it. I'm using cubeIDE to generate code for 1-bit mode SDIO interfacing using DMA. But the problem is at f_open instruction while debugging step by ...
I am getting suspiciously high current draw (10mA) after I callHAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI);and I'm trying to track down the culprit, I'm suspending the systick but it makes no change.In stm32f0xx_hal.c it list...
Hi All,I am using SD card store something log on H743 with mbed. But I encounter a problem which will poll the strange status "HAL_SD_CARD_RECEIVING".I can initial without any issue. Also can write a shot address and read. But when I write a contin...
Hello,I'm trying to connect my MPU6500 to my Nucleo f411re board with the SPI Protocol.The MPU6500 is working correctly because I tested it with an Arduino and it worked as expected.I'm using SPI2 with the Pins PB15, PB14 and PB13.But for some reason...
I have added a bootloader to my code with 0x4000 size. I added SCB->VTOR = 0x8004000 before memory jump from bootloader to app code and I also added SCB->VTOR = 0x8004000 at the first line in the app code main.c . The memory jump works well. My free...
Hey,i want to implement a Modbus TCP IP client on my STM32L432KC board.is there a good libary you would recommend me? iam using a W5100 Ehternet shield connnected via SPI.i want to read/write holding registers on the Modbus master..thanks!
Hello ,I am migrating code from STM32H7 to STM32F4I face the following problems with SPI,1-Hardware output NSS pulses is activated only with HAL_SPI_Init/HAL_SPI_DeInit.2-There should be a pull up on the NSS in order to reach 3.3V and it can't work w...
Datasheet: "Interrupt flag is raised when the content of the Counter register (LPTIM_CNT) matches the content of the compare register (LPTIM_CMP)."Some forums: "Compare match Interrupt flag is raised if CNT >= CMP and not CNT = CMP"(Cf. https://commu...
just comment the code whitch set the pin to enable the predriver device, the interrupt will be normal, hope your reply, thank you.
on those rising edge with interrupt and i need to count each time.secondly i need to use another timer and set its frequency to 100KHZ with interrupt mode. i need to use counter to count at each interrupt. thirdly based on that counter i need to cal...
