UG-2864HSWEG0或ssd1306與stm32源程序+Proteus仿真

ID:771565 · 發(fā)表于 2020-6-18 02:48

我在做這個仿真的時候也遇到了一定問題，現(xiàn)附上proteus仿真模擬圖和源代碼供大家參考。大家在用這塊屏幕取字模的時候一定要注意是行列式還是列行試。注意在打印數(shù)組的時候要注意他的頁與行的變換。加油

仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）

單片機源程序如下:

#include "usart.h"
#include "delay.h"
//unsigned char a[10]="mengxinyu";
unsigned char a[]={//孟
