VK1056驅動程序，在STM32F103下可以運行，51單片機可以自己小改，后面附上封裝和數據手冊

單片機源程序如下:

#include "vk1056b.h"
#include "delay.h"
const u8 vk1056B_segtab[9]={14,15,16,17,18,19,20,21,22};
u8 vk1056B_addrbit=6;//驅動ic的ram地址線數A5-A0,
u8 vk1056B_segi,vk1056B_comi;
u8 vk1056B_dispram[14];//顯示RAM buffer只使用低4位，bit0->com0,bit1->com1,bit2->com2,bit3->com3
u8 vk1056B_myram[4]={0x00,0x00,0x00,0x00};
