[设计过程分享] MAX32630FTHR进程(3)驱动SPI屏

ddllxxrr 2017-7-18 20:41 楼主

这个屏可累死我了，星期天搞一天也没搞定，一量管脚电压1.8V，后来看例程，原来得调一个库，再加一个语句就可以直接驱3.3V的屏了。说也奇怪用硬件SPI总是不行，后我用软件模拟一次成功。首先，要把管脚变为3.3V的。这个可以用那个库max32630fthr，可以参考https://developer.mbed.org/teams ... HR_IMU_Hello_World/ 可以先把库倒进mbed然后再把那个库考到自己的工程目录下边，然后在程序前面加上: MAX32630FTHR pegasus(MAX32630FTHR::VIO_3V3); 前面加上：#include "max32630fthr.h" 以下是程序：

#include "mbed.h"
#include "max32630fthr.h"
//SPI device(P5_1, NC, P5_0);
DigitalOut CLK(P5_0);
DigitalOut DATA(P5_1);
//DigitalIn(P4_4);
//DigitalIn(P4_5);
//DigitalIn(P4_6);
//这是我的板子上面的引脚分布图，SPI协议引脚都有在上面
typedef unsigned char uchar;
typedef unsigned int uint;
DigitalOut rs(P3_5);
DigitalOut LED(P3_3);
//RS,是这种液晶屏幕的一个重要引脚，也常常标记为PC
DigitalOut cs(P3_4);
//CS与片选使能还是有一定区别
DigitalOut reset(P3_2);
//RESET复位引脚
MAX32630FTHR pegasus(MAX32630FTHR::VIO_3V3);
