This time, we use the four LEDs and the "Wakeup" button on the GD32L233C-START board to conduct experiments, and learn about the GPIO and EXTI (external interrupt resources) of GD32L233CCT6 through si
1. Globally modify the character size. Generally speaking, the component number and key parameters are marked near the components of the formal PCB,but some pure SMD circuit boards are relatively smal
EMI pre-compliance test and debugging have become an unavoidable problem for engineers in electronic product design.It is difficult to pass the expensive EMI compliance test in one go.It is difficult
