Recently, I found a board with a power input of 48V, and found a chip XL7005AProblem: 1. The switching frequency of this chip is only 150K. To reduce the ripple, you have to increase the inductance, w
Recently, I need to make a CAN adapter with USB interface for device online setting and online upgrade. STM32 has many integrated CAN, here only USB port and CAN port are needed. It is said that the l

MSP430 provides a very rich interrupt source, including IO interrupt, timer interrupt and some interface interrupt (SPI, UART, I2C) and so on.Let me share with you some features of MSP430 interrupt.Fi
This paper discusses the method of using phase-locked technology to generate low-frequency signals with high frequency stability, and introduces the design of a low-frequency phase-locked loop functio
