In modern radar systems, DSP-containing circuit boards are widely used. DSP-containing circuit boards are usually based on a certain DSP chip as the core, and are equipped with dual-port RAM (DRAM) an
Applicable to EM35XX and EFR32 platforms.Low-power devices are divided into several modes. In normal development, the EM2 mode of sleep is generally selected, so here we will mainly talk about the pro
Many MCU developers do not understand why a ground capacitor is required on each side of the MCU crystal, because this capacitor can sometimes be removed. The author has referred to many books, but fo
SPI is a high-speed, full-duplex, synchronous communication bus, and only occupies four wires on the chip pins, saving the chip pins and saving space on the PCB layout, providing convenience. It is ma
