Switching frequency optimizationGenerally speaking, the higher the switching frequency, the smaller the size of the output filter components L and CO. Therefore, the size of the power supply can be re
High-speed digital signals are determined by the edge speed of the signal. It is generally believed that a rise time less than 4 times the signal transmission delay can be considered a high-speed sign
The GPIO interface can be configured in general input and output mode (software mode is GPIO mode) or (hardware mode is peripheral mode). The GPIO interface mode is configured in software mode and can
Before porting, here is a picture of the effect. I was really happy when the development board displayed this picture for the first time, because it was my first time to use emwin. The porting process
