This article is applicable for STM32H74x, STM32H75x, STM32H72x, or STM32H73x microcontrollers. We often see developers facing issues with these microcontrollers when they need to use BDMA, or DMA to transfer data to/from the RAM, but no transfer is...

Introduction Many customers requested to have FDCAN communicating at 8 Mb/s. We provide a GitHub hotspot that contains a simple project on several STM32 part numbers. The project allows for FDCAN to reach a bit rate of 8 Mb/s in the data phase. The ...

Introduction For cost reasons, many ST boards do not feature an external Crystal to feed the STM32’s system clock over the high-speed external clock (HSE). On the other hand, some peripherals need a precise clock source to work and behave correctly...

Introduction STM32 MCUs users may face an issue with CAN message reception mainly when the CAN2 instance is used. This issue may appear even if the hardware setup is correct, and CAN bit time and filters are configured correctly. If the value of Sta...

Introduction CAN bus is a robust protocol to transmit/receive data. It can be very sensitive to any issue that could lead to communication errors or even halt communication. STM32 users need to have a basic knowledge of the CAN bus (protocol + hardwa...
