What are the similarities and differences between the IO port simulation serial port, PWM, IIC functions and the serial port, PWM, IIC built into the chip hardware?
Use the u8g2 library to drive the display screen using SPI
The development board ESP32-S3-DevKitC-1 is wired as follows: /* clock=*/13, /* data=*/11, /* cs=*/10, /* dc=*/9, /* reset=*/8Call the routin

The current limiting IC (TI TPS2559) is connected to the front end of the input.
[size=3] As an energy conversion device working in the switching state, the voltage and current change rate of the switching power supply is very high, and the interference intensity generated is rela
Hello everyone~ I made a board and found a problem when soldering: When making a double-layer board, some of the chip pins are connected to the front wiring, and some are connected to the back wiring.
