给你说说我用的这两个函数OLED_ShowString(2, 1, Temp: ); OLED_ShowNum(2, 7, a_temp, 2);这两个函数放在循环里稍晚程序就可以工作了 OLED_ShowString(2, 1, Temp: );这个第一个形参注意括号里的ab这个ab叫形参别被别人笑话赶明我被别人笑话过填第几行第二个填第几列第三个填你要显示什么。我写的这句就是在第二行第一列写Temp:OLED_ShowNum(2, 7, a_temp, 2);这句第一个形参也是第几行第二个也是第几列第三个就是你要显示什么变量第四个就是这个变量给他多大长度。我写的这句就是在第二行第七列把温度这个变量实时显示出来这个变量我给他两位的空间。OK 不出意外你的OLED 屏幕烧完程序应该可以显示了。我是一个不废话又不太懂废话的博主不定期更新一些自己用过的小模块还可能会发一些关于无人机的操作哦~------------如有侵权请提出---------------必改正----------
