I encountered a hard error problem, it appeared at a seemingly random time, the pointer points to address A5 or FF (I allow memory space is much lower than 80000000 and above). It seems A pointer t

STM32 multi-block CAN bus interconnection card dead problem
There is no problem when a single board is connected to the CAN bus, but when multiple boards are connected to the CAN at the same time, basically only one can be used, and the other boards will be
Pixy & STM32 Usage Records (Serial Pull & SPI Peripherals)
First, steadfastly figure out the stm32 peripheral serial port and SPI, don’t look down on trivial matters. Use SPI communication to read out the data of pixy, send the data to the serial port assi

The storage media corresponding to the three boot modes of STM32 are all built-in chips. They are:
1) User flash memory = Flash built into the chip.
2) SRAM = The RAM area built into the chip is

STM32 serial optoth experiment
In experimental phase 1, the timer is timed for 1s to trigger an interrupt, and data is sent out during the interrupt.
The timer is set to 36000 frequency division, the period is set to 2000,
