12864液晶用STM32驱动成功附程序

ID:104835 · 发表于 2016-2-1 01:19

试了两天终于成功了。

我写的这个程序，如果大家要参考移植的话，12864.c这个文件一个字也不用动，所有需要移植的部分我全部写到12864.h文件来了。方便大家查看。

这两天发现几个问题特别需要注意一下。

一。要开启功能复用IO口时钟，我用的是PB口。STM32F10x系列的MCU复位后，PA13/14/15 & PB3/4默认配置为JTAG功能。有时我们为了充分利用MCU I/O口的资源，会把这些端口设置为普通I/O口。所以要关闭 JTAG 。

二。写液晶指令或者数据的时候要注意，出错的话也是不能显示的。我用宏定义来写。
#define LCD_WriteData(x) {LCD12864_GPIO->BSRR = x<<8 & 0xff00;LCD12864_GPIO->BRR = ((~x)<<8) & 0xff00;}
//高8位的数据

三。PB2是BOOT1，这个脚不要用，不然USB线下载不进去。

四。因为液晶要检测忙状态，所以控制的5个引脚我设置成推挽输出模式，但是8个数据引脚PB8~PB15我设置成开漏输出模式。在开漏模式状态下，对输入寄存器的读访问可获得I/O端口状态。PB15为忙状态检测位。

耐心做。没做出来的话之前的付出都白费了。

请教下，我想把这个程序移植到stm32f103ZE芯片上，需要注意什么啊？我直接吧你程序中对应的IO口插上就可以了吗？
