I am new with the STM32 MCU and this is my first projectI am using a STM32F407VGT6I started a project that read a 16bit parallel on PDx GPIO. The data is placed by an external device and a signal is set to low for 400ns. I connected that signal on PB...
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...
Hey, I just want to report an error in the Reference Manual for the STM32F411xC/E microcontroller.Reference Manual: https://www.st.com/resource/en/reference_manual/rm0383-stm32f411xce-advanced-armbased-32bit-mcus-stmicroelectronics.pdfPublished on: h...
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...

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？
I am working on FDCAN communication using an STM32G0B1CCT6 microcontroller. I am trying to perform a simple Tx/Rx loopback test (and later communication with external tools like Vehicle Spy), but I am facing the following problem: FDCAN is not trans...
Hello, I'm using two H533 Nucleo Boards and I'm trying to establish an I3C communication between them. There are no specific examples for this protocol using two of these boards, instead there are only examples for a sensor which I don't have. So, I ...
