Basic concepts of RF power amplifier
The RF power amplifier (RF PA) is the main part of the transmission system, and its importance is self-evident. In the front-stage circuit of the transmitter, the ...
GD32F350 uses Timer1. According to the routine, channels 1, 2, and 3 generate PWM signals normally. When channels 2 and 3 are not used, the PB10 pin has an irregular waveform output, which is suspecte...
I downloaded the routine for playing sound, and listened to it, but it was just one sound and then it was over.
So I modified it and added a loop in the main function:
#include app_config.h
#include a...
