I am running an STM32L476RG at 1.8V and have noticed that I2C-3 does not generate a clock or data signal. I have tried isolating the MCU from the rest of the circuit and found that there is still no signal at the MCU pins, so i know the circuit is no...
Hi,I'm trying to use QSPI to interface with a flash memory chip (GD25Q16). I can read and write to memory and status registers using blocking code, but I'd like to use DMA to decrease the CPU load. However, the QSPI handle's State gets stuck in HAL_Q...
I'm using STM32CubeIDE/MX to program and debug a simple demonstration of UART on the B-L475E-IOT01A development board (with integrated STM32L475VG). The code is straightforward (and autogenerated, apart from the hello world message).Probing the pins ...
Hello, my STM32L011's core is running at 32 MHz. I use systick for 1 ms interrupt. However, if i try to use the WFI inside my while loop in my delay function, the timebase changes from 1 ms to 6.28 ms. Any help is appreciated!#include "user_systick.h...
Hey Guys, iam trying to convert Arduino Code to my C Project in CubeIDE..I have some troubles(=warnings and iam unsure) with the SPI Trasmit functions.Could you tell me if my code does the same as the Arduino Code?ARDUINO : ******************* void ...
We are Planning to Use STM32F7508-DK board for our Application. As I go through Datasheet of it. It is mention that 64 KB for internal flash. But I am very sure that my application required more than 64 KB. Question : Can we use QSPI Flash in case ...
peripheral settings done properly.STM32F401RE -- has settings DMA2 & GPIOA (PIN_10 & PIN_11).STM32L431CC -- But i have configured -- DMA1 & GPIOB(PIN_10, PIN_11).Data Transmission & Reception not happening. any suggestions .
I'm trying to use a SDcard on a STM32H7A3ZI and hitting a roadblock. Everything in the initialisation wotks until the SD_SendSDStatus function in stm32h7xx_hal_sd.c. This fails as it never sees __HAL_SD_GET_FLAG(hsd, SDMMC_FLAG_RXFIFOHF) and always ...
i used SDIO project to read micosd card in STM32 Standard Peripheral Librarieswhen i upload code and debug__IO SD_Error errorstatus = SD_OK; uint32_t response = 0, count = 0, validvoltage = 0; uint32_t SDType = SD_STD_CAPACITY; /*!< Power ON Sequence...
Hello,I have a STM32F301K6 based board and it seems that the I2C HAL driver is not working properly. I have a little test software running which should receive one byte (0x00) and send back 5 bytes (0x01 to 0x05) periodically.Receive works fine but t...
