How important is power supply? How does it work? What are the different types of power supplies? What conversion methods are used? How does power affect the signal chain? How to choose the best regulator for your circuit? This video will also explain the effects of noise, ripple, line and load regulation, power supply rejection ratio, temperature changes, and other specifications that affect power supply performance.
I used to be able to communicate normally by simulating SPI through GPIO, but now I always fail to use native SPI to realize communication. I have been adjusting it for several days but it still doesn
The hardware developed is a mips architecture CPU~ I am so frustrated~ I edited bootrom.bin in dos, burned it into flash and observed the running status by lighting up the lamp. There is no problem co
