STM32F405RG换成STM32F413RG后CAN不能工作
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？

Resolved! FDCAN Not Transmitting or Receiving on STM32G0B1CCT6
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...
Resolved! Different stm32F103 behaving differently
I have purchased STM32F103c8t6 microcontrollers from three different vendors, but they are behaving differently.I am working on CAN, and on the microcontrollers from one vendor, it is working properly. But on the microcontrollers from other two vendo...
Resolved! PWM jitter
Hello, I am currently in the midst of developing a super simple system to create a varying load. It's basically to resistors in series with a transistor in parallel of the second resistor. The transistor is driven by a PWM signal to bypass the secon...

Differences in Flash Error Occurrence by Code Location(SRAM,DTCM) in STM32H7
Hi, I found a pretty interesting issue while developing an STM32H7 Series MCU.And I tried many things to figure out the cause but failed. T^T If you have experienced similar symptoms or know anything about them, I hope we can discuss it together here...
Resolved! STM32H7B3VIH6's LTDC does not generate pixel outputs
All control signals seem to be good: `DEN`, `VSYNC`, `HSYNC`, `CLK`. but pixel signals (R0 ~ R7, G0 ~ G7, B0 ~ B7) are always low. 1) DEN. 2) HSYNC. 3) VSYNC. 4) CLKalthough control signals correctly work, no pixel data lanes do not. Code that genera...
Resolved! STM32H7RSxx TRM: MDIO CSR
Hi,The STM32H7RSxx TRM specifies, for ETH_MACMDIOAR, the following CSR values: Bits 11:8 CR[3:0]: CSR Clock RangeThe CSR Clock Range selection determines the frequency of the MDC clock according tothe CSR clock frequency (eth_hclk):0000: MDC clock ...
