What are the types of CAN bus faults? How to detect

Since the CAN network uses multiple protocols, the port of each control module has a standard voltage under normal circumstances. Therefore, the voltage measurement method can be used to determine whether the line has a short circuit to ground or power supply, a short circuit between phase lines, etc. In order to d

STM32 download and debug mode interface

The most commonly used debugging methods are JTAG and SWD. JTAG: JTAG (Joint Test Action Group) is an international standard test protocol (IEEE 1149.1 compatible), mainly used for internal chip testing. Most advanced devices now support the JTAG protocol, such as ARM, DSP, FPGA devices, etc. The standard JTAG inte

STM32 external door dog (iwdg)

The independent watchdog (IWDG) is driven by a dedicated 40kHz low-speed clock. It is still effective even if the main clock fails. The window watchdog is driven by a clock divided from the APB1 clock and detects abnormal late or early operation of the application through a configurable time window. IWDG is most s

STM32 study notes-SysTick

1 Introduction The SysTick timer is bundled in the NVIC and is used to generate the SysTick exception (exception number: 15). In the past, the operating system and all systems that used a time base had to have a hardware timer to generate the required "tick" interrupt as the time base for the entire system. The tick
