sprintf is a function in the C language library that converts data types. There is a situation where In 51 MCU, define unsigned char temp; Then I want to use the serial port to print out temp in deci...[Details]
Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]
STM32 has two watchdogs: independent watchdog and window watchdog. This article mainly introduces the use of independent watchdog. Independent watchdog (IDWG): driven by an independent 40KHZ low-sp...[Details]
A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]
As shown in the figure, the author soldered a STM32F207VET6 board using a TQFP (32-100PIN) 0.55MM to direct plug adapter board. The board leads out the SWD debug interface (only PA13 and PA14 are occ...[Details]
