第七届工程训练大赛-物流机器人.zip

Thanks https://github.com/bitbank2/MAX7219 I made some modification based on that lib. For my personal function, write your main.c like this ```c //include header files #include "MAX7219/max7219.h" #include "MAX7219/max7219_matrix.h" //init MAX7219 MAX7219_MatrixInit(&hspi1, MAX7219_CS_GPIO_Port, MAX7219_CS_Pin); MAX7219_MatrixUpdate(); //prepare the numbers you want to show uint8_t colororder[]={1,3,2,3,2,1}; //use MAX7219_mywrite(uint8_t *numstr) to flush the buffer MAX7219_mywrite(colororder); //use MAX7219_MatrixUpdate() to display the numbers MAX7219_MatrixUpdate(); ```
