STM32World Rant #2 - MYSTERIOUS UNKNOWN MCUJust a short rant about the MYSTERIOUS STM32F402. This MCU does NOT exist in ST's catalog, and yet you can readily buy them in China. In this video I will go through the datasheet, find a comparable MCU whic...
Hi,I'm looking at implementing USB on my the NUCLEO-64 STM32F303RE EVAL BRD, with of course the STM32F303RE microcontroller. I'm having issues understanding what alternate function is needed for the USB-DM and DP pins. In the datasheet https://www.st...
Hello, I have the following problem - I configured TIM2 of STM32H723 in Encoder Mode following all recommendations in the Reference Manual RM0468, chapter Encoder Interface Mode, p. 1694: • CC1S= 01 (TIMx_CCMR1 register, TI1FP1 mapped on TI1)• CC2S= ...
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...

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？
