HC32L110C6PA minimum system

    This project uses the HC32L110C6PA-TSSOP20 chip purchased by Moubao. It is equipped with 1 SMD LED, 1 RESET button and 1 user button. It leads to the SWD debugging interface to connect to the DAP debugger and leaves space for input and stabilized power supply. Test point. Due to space constraints (SMD crystal oscillators are expensive), no external crystal oscillator is shown. Please pay attention when programming. Other explanations are as follows:
    1. An L is added before the name of the power supply in the schematic diagram to facilitate manual imposition and can be deleted. The welded one is put together with other boards and cut and polished manually.
    2. The device 0402 in the schematic diagram can be changed to 0603, and the XC6206 on the back temporarily uses 3.3V.
    3. The pin header positions on both sides are not compatible with breadboards. Please adjust them yourself if necessary.
    4. In the circuit diagram, the specific uses of TSTP1 and TSTP2 are not thought out, so the positions of the resistors are reserved first.
