spc56怎么通过UART编号和文本字符串在终端上接收

你好，

我正在我的电路板上写一个测试程序（xpc56xx evb主板），我希望通过UART编号和文本字符串在终端上接收。当我在串行终端（RealTerm）上获取数据时，我收到了正确的字符串（'测试程序启动'）但不是变量的值（pcval1，pcval2，pcval3）。 （见截图）。

这是我的代码：#include'component.h'
uint32_t volatile * pcval;

uint32_t volatile cval;
uint32_t volatile * pointer1;
uint32_t volatile * pw;
uint32_t volatile w = 0x000FFF; uint32_t volatile giri1，giri2，giri3;

/ *
*申请入境点。
* /
int main（void）{/ *按照指定的顺序初始化所有导入的组件

应用程序向导。该功能自动生成。* /
componentsInit（）; giri1 = 00000001;

giri2 = 0x00000002;
giri3 = 0x00000003;
/ *
*使用驱动程序默认配置激活串行驱动程序1。
* /
sdStart（＆amp; SD1，NULL）;

/ *应用程序主循环。* /
而（1）{
未签名的我; osalThreadSleepMilliseconds（100）;

osalThreadSleepMilliseconds（100）;
osalThreadSleepMilliseconds（100）;
osalThreadSleepMilliseconds（100）; chnWriteTimeout（＆amp; SD1，（uint8_t *）'测试程序开始 r  n'，20，TIME_INFINITE）;

chnWriteTimeout（＆amp; SD1，（uint8_t *）'测试程序开始 r  n'，20，TIME_INFINITE）; giri1 = giri1 + 1;

pcval =安培; giri1;
chnWriteTimeout（＆amp; SD1，（uint8_t *）pcval，4，TIME_INFINITE）; giri2 = giri2 + 1;

pcval =安培; giri2;
chnWriteTimeout（＆amp; SD1，（uint8_t *）pcval，4，TIME_INFINITE）; giri3 = giri3 + 1;

pcval =安培; giri3;
chnWriteTimeout（＆amp; SD1，（uint8_t *）pcval，4，TIME_INFINITE）; chnWriteTimeout（＆amp; SD1，（uint8_t *）' r  n'，2，TIME_INFINITE）;

}
是否有一个策略，我可以读取正确的值？


先谢谢你！

Hello,

I am writing a test program on my board (xpc56xx evb motherboard) and I want to receive on my terminal throught the UART numbers and text strings.When I get the data on my serial terminal (RealTerm) I  receive properly the strings ('Test program start')  but  not the variables' value   (pcval1,pcval2,pcval3). (see screenshot).

This is my code:#include 'components.h'
uint32_t volatile *pcval;

uint32_t volatile cval;
uint32_t volatile *pointer1;
uint32_t volatile *pw;
uint32_t volatile w = 0x000FFF;uint32_t volatile giri1,giri2,giri3;

/*
* Application entry point.
*/
int main(void) {  /* Initialization of all the imported components in the order specified in

     the application wizard. The function is generated automatically.*/
  componentsInit();  giri1=0x00000001;

  giri2=0x00000002;
  giri3=0x00000003;
  /*
   * Activates the serial driver 1 using the driver default configuration.
   */
  sdStart(&SD1, NULL);

  /* Application main loop.*/
  while (1) {
    unsigned i;    osalThreadSleepMilliseconds(100);

    osalThreadSleepMilliseconds(100);
    osalThreadSleepMilliseconds(100);
    osalThreadSleepMilliseconds(100);      chnWriteTimeout(&SD1, (uint8_t *)'Test program startrn', 20, TIME_INFINITE);

      chnWriteTimeout(&SD1, (uint8_t *)'Test program startrn', 20, TIME_INFINITE);      giri1=giri1+1;

      pcval=&giri1;
      chnWriteTimeout(&SD1, (uint8_t *)pcval,4,TIME_INFINITE);      giri2=giri2+1;

      pcval=&giri2;
      chnWriteTimeout(&SD1, (uint8_t *)pcval,4,TIME_INFINITE);      giri3=giri3+1;

      pcval=&giri3;
      chnWriteTimeout(&SD1, (uint8_t *)pcval,4,TIME_INFINITE);      chnWriteTimeout(&SD1, (uint8_t *)'rn',2,TIME_INFINITE);


  }
}is there a strategy with I can read proper values?


Thank you in advance!
