0.96OLED 4针IIC STM32标准库版本
在前面已经介绍过,这里就不多说了,详情请见: 0.96OLED 4针IIC STM32HAL库版本
另外,本人在代码中封装了一个OLED显示的接口,方便开发者对字符显示位置的快速定位,以及像C语言printf()函数一样在屏幕上进行int,float,char等变量的格式化输出。非常方便实用。
封装接口
原先用这个oled库提供的接口使用x,y定位坐标计算比较麻烦,因此做了一个宏进行封装。
可变参数宏:
char txt[16];
#define display(row, col, size, ...) {sprintf((char*)txt, __VA_ARGS__); OLED_ShowString(col*8, row*(size==16?2:1), txt, size);}
接口原理
学过C语言应该能看得懂display()
宏的实现过程。
首先需要在调用前声明一个txt
的字符数组。然后使用sprintf()
将字符串和需要格式化输出的变量打印到txt
数组中,再用oled原始显示函数OLED_ShowString()
来显示txt
中的字符串。
然后关于位置则是判断size
的大小然后对oled原始显存坐标进行换算,即x乘以宽度,y乘以高度。
再根据人的使用习惯先确定行,再确定列,将xy的参数对调。
这样一个简单的封装就完成啦。
唯一的难点是关于printf()
中参数可变的封装,具体可以搜索C99中的可变参数宏的使用了解学习。
关于接口怎么用,参数的范围,还是看我上一篇文章: 0.96OLED 4针IIC STM32HAL库版本
oled源码
关于移植的问题,只需要修改oled.h
中的IIC引脚定义宏就行。具体如下:
为了方便管理,把所有的引脚都用宏重新封装了一遍,放在自己创建的main.h文件中。
废话不多说,上源码!
