求助:MSP430F413驱动液晶有重影!!!

只看该作者 · 2010-12-14 02:15

初用413,竟然遇到这样的问题,硬件软件全检查了,还是没找到原因,头疼啊!
跪求协助啊!!!!!!!!!!^-^
413配置的是4MUX模式,外接32.768K晶振,LCD驱动直接用ACLK,外部R03接地,1/3偏置电阻680K,因为PCB布板问题, 段口随意连接(4COM,10个段口,5位数字LCD)!

以下程序在LCD上显示:12345

#include  <msp430x41x.h>
char digit[10] = {
0xE7,  /* "0" */
0X06,  /* "1" */
0X6D,  /* "2" */
0X4F,  /* "3" */
0X8E,  /* "4" */
0XCB,  /* "5" */
0XEB,  /* "6" */
0X46,  /* "7" */
0XEF,  /* "8" */
0XCF /* "9" */
};
char LCD[10];
void LCD_W()
{
  LCDM3 = LCD[4];

  LCDM5 |= LCD[3]>>4;
  LCDM4 |= LCD[3]<<4;

  LCDM8 |= LCD[2]>>4;
  LCDM6 |= LCD[2]<<4;

  LCDM11 |= LCD[1]>>4;
  LCDM9 |= LCD[1]<<4;

  LCDM12 |= LCD[0]>>4;
  LCDM11 |= LCD[0]<<4;
}
void main(void)
{
   int tmpv;
   WDTCTL = WDTHOLD + WDTPW;    //关闭看门狗

   BTCTL  = BTSSEL;                      // set LCD 时钟
   P2SEL  |= 0x38;
   P3SEL  |= 0x49;
   P4SEL  |= 0x16;
   P5SEL  |= 0xFC;                      // 置为外围模块
   LCDCTL = LCDON+LCD4MUX+LCDSG0_3;       // 4Mux 模式

   for (tmpv = 0;tmpv<13;tmpv++)
   {
      LCDMEM[tmpv] = 0x00;             //clear LCD
   }
while(1)
{
   for (tmpv = 0;tmpv<5;tmpv++)
      {
         LCD[tmpv] = digit[tmpv+1];             //clear LCD
         }
   LCD_W();
   }
}
请各位大虾帮帮忙啊!!!!!!!急啊^^^^^^^^^^^
