I'm using STM32 with HAL and LL drivers (H7 and G4 families, in particular, but I think this can be a general question) and I trying to avoid being forced in recursive faults when reading a flash location with broken ECC. In my application it may hap...
Hi,I used to run my STM32F303RE at 72Mhz clock from a 8Mhz CMOS oscillator. . Timers8/1 operated at 72Mhz as well. That worked fine. I had to change the CMOS oscillator from 8 to 24Mhz.I tried two modifications, see attachment:a) I changed PLLMul fro...

Hi all.I have this piece of code: __HAL_RCC_CORDIC_CLK_ENABLE(); CORDIC->CSR |= CORDIC_CSR_NARGS; CORDIC->CSR |= (CORDIC_CSR_PRECISION_3 | CORDIC_CSR_PRECISION_2 | CORDIC_CSR_PRECISION_1 | CORDIC_CSR_PRECISION_0); CORDIC->CSR |= CORDIC_CSR_FUNC_1...
Hello,I am currently trying to use the EMW3080 Wi-Fi chip on the B-U585I-IOT02A over SPI. I am using the Keil µVision IDE and I am trying to use a bare-metal approach without a HAL. I am trying to send data over to ThingSpeak from the temperature and...

Hi, I am working with STM32H757I-EVAL. The task is to record audio, store it in SD Card. Since, STM32H757I-EVAL has PDM Data format as well as DFSDM data format which would be better to interface with or is there anyother data format that can be used...
Hi,I have 2GB emmc on SDMMC1 bus.I wish to have first 1GB (0~1GB) as application code area and the rest 1GB(1GB~1GB) as FAT file system that access by user as USB MSC. Even more, the first 1GB i wish to have 2 partitions(like A-B bank) for fail safe ...
I'm using a Nucleo-F446RE board and have successfully flashed my application code to Sector 5 of the internal flash memory. The code runs correctly right after flashing, but it does not run after a reset or power cycle. It seems the MCU still boots f...
最近项目需求更改，原来的STM32F405RG换成STM32F413RG，其他外设均调正常，只有CAN不能工作（只使用到CAN1）。请问除了以下差异之外还需要调整哪里？
