I'm struggling to understand why I'm seeing a huge performance hit by slightly changing code in a loop. I narrowed down the problem to a manageable code size, and I'm hoping someone here can suggest how to investigate and resolve my issue.I'm using a...
Hi All,I am using STM32F427ZIT6 MCU for one project. I connected SPI4 for two different interfaces by mistake. Pins 1,4,5 for one interface and pins 64,65,66,67 for one interface.I want both the devices working simultaneously. Is there any solution f...
Apparent bug in the header file? Best I can tell, the Interrupt Priority Mask Table that follows appears correct?
I'm using STM32F779II With a microsd card. That is clocked at 48MHz.When writing to the sdcard as a block, I get HAL_TimeOut, using that function: err = HAL_SD_WriteBlocks(&sd_handle, (uint8_t *)src, block_num, num_blocks, 6000);After writing I wait ...
Hi, I am using an STM32f407VGT MCU and I am trying to receive a burst of data of 112 bytes from SPI1 and storing it in an array buffer, initially set with all its elements to 0.According to the RM0090 TRF this should be easily done with the DMA, but ...
Hey everyone, I am using IAR and a STM32F401RE.When I am setting the library low-level interface implementation to "None", I get the following linker error:Error[Li005]: no definition for "__write" [referenced from fflush.o(dl7M_tlf.a)]Error[Li005]: ...
HI Sir.I will try to work on a project using STM32.I have a question regarding flash memory usage.I want to save input data to flash memory but STM flash memory is divided sector.The capacity of each sector is determined.ex) STM32F205VE Sector 0 : 1...
hii want to have both SDMMC 1 and 2 i test my project for SDMMC1 in 4bit sdio at 44MHz and no clock Div its work good singlebut when i set SDMMC2 single with that not worki change setting reduce frequency , use clock div , software pull up pins but ...
I get the errorError in final launch sequence:Error in initializing ST-LINK device.Reason: (4) No device found on target.I have the STM32 F303 RE nucleo connected over USB and am trying to download and run code through STM32Cube IDE. Code compiles fi...
