PCB diagram
In addition to using a marker to write your message on the soldered PCB greeting card, you can also use LCEDA to open the PCB.JSON file and draw other images and text on it.
(Special note: When placing an order for PCB, if you want to use other ink or marker colors, please note that the ink color cannot be the same as the marker used.)
When using STC_ISP to download the program, use the serial port download method, and fill in the internal IRC frequency as: 10MHZ. The compiled HEX file has been attached (see the picture below), and you can burn it directly. It is recommended to use 3.6V LIR2032 rechargeable lithium battery to ensure sufficient brightness
Program files, including sys.h and main.c, must be placed in the same KEIL project.
