请教NAT9914的问题

怎么样才能知道读写寄存器成功呢？
我按照官方资料上的测试程序

/* Test 1 - check ADSR and ISR0 by programming to talk with 'ton' */
struct ck       t1[] = {
   {WT, tauxmr,0x15},     /* switch to 9914 mode */
   {WT, auxcr, 0x1c},     /* reset chip */
   {WT, auxcr, 0x80},     /* reset chip */
   {WT, auxcr, 0x00},     /* reset chip */
   {WT, auxcr, 0x1e},     /* page in to imr2 */
   {WT, imr2,  0x00},     /* clear GLINT bit and imr2*/  
   {WT, imr1,  0x00},     /* clear imr1 */
   {WT, imr0,  0x00},     /* clear imr0 */
   {WT, auxcr, 0x8a},     /* 'ton' */
   {RD, isr0,  0x10},     /* BO bit set - no interrupts */
   {RD, isr1,  0x00},
   {RD, adsr,  0x02},     /* 9914A is TADS */
   {WT, auxcr, 0x0a},     /* clear 'ton' */
   {RD, adsr,  0x00},     /* TADS cleared */
{0}};
我读出来的数据一直都是不对的。



硬件连接时这样的

读写子程序是

void outp(unsigned char  abc,unsigned char o_data)
{unsigned char xdata *io_address;
io_address=abc<<8;
  *io_address  = o_data;
}
unsigned char  inp(unsigned char abc)
{unsigned char temp;
unsigned char  xdata *io_address;
io_address=abc<<8;
temp= *io_address ;
return temp;
}

RS0-2接的是P2.0-2

void outp(unsigned char  abc,unsigned char o_data)
{unsigned char xdata *io_address;
io_address=abc<<8;
  *io_address  = o_data;
}
unsigned char  inp(unsigned char abc)
{unsigned char temp;
unsigned char  xdata *io_address;
io_address=abc<<8;
temp= *io_address ;
return temp;
}

高手帮帮忙
看下错误在哪里

大哥，这个我想帮你看的人应该很少的。靠自己吧

请问你后来问题解决了吗？

没玩过这东西。这种带程序的楼主还是自己慢慢摸索靠谱点。或者直接有已经搞好的模块，在那个基础上修改

楼主解决了吗？，最近在学习GPIB，但NAT9914一直没有读写成功，读回来的都是0XFF，为什么呢？能否一起学习，QQ：486053668
