控制OLED屏滚动

左耳 · 发表于 2016-4-10 19:49:58

点亮OLED  软件控制滚屏  原来用51板（12M）做的  滚的很快  为什么换了430（8m）后就明显慢了好多我换了430的晶振（16M)  赶紧几乎没快起来  为什么呢？
我的板子的测试程序如下（可以点亮OLED）：
#include  "main.h"
#include  "zimo.h"
#define EN_H  P4OUT|=BIT1
#define EN_L  P4OUT&=~BIT1

#define WR_H    P5OUT |= BIT0
#define WR_L    P5OUT &= ~BIT0
#define RD_H    P5OUT |= BIT1
#define RD_L    P5OUT &= ~BIT1
#define RES_H    P5OUT |= BIT2
#define RES_L    P5OUT &= ~BIT2
#define DC_H    P5OUT |= BIT3
#define DC_L    P5OUT &= ~BIT3
#define CS_H    P5OUT |= BIT4
#define CS_L    P5OUT &= ~BIT4

原理图功能实现都没问题，但因为这是个低功耗产品，这板子目前实现起来有问题，呵呵
