在cc2530f256中利用串口助手实现cc2530单片机与pc收发“姓名+学号”

首先，需要在cc2530f256单片机上配置好串口通信的参数，例如波特率、数据位、停止位等等。可以参考cc2530f256的数据手册或者开发板的示例程序。

然后，需要在单片机上编写代码实现串口收发。以下是一个简单的示例代码：

#include <ioCC2530.h>

#define UART_TX P0_5
#define UART_RX P0_6

void UART_Init(void)
{
  PERCFG &= ~0x01;   // USART0 alternate 1 location (P0.2-P0.3)
  P0SEL |= 0x0C;     // Enable peripheral function on P0.2 and P0.3
  U0CSR |= 0x80;     // Mode: UART Mode
  U0GCR |= 11;       // Baud rate = 115200
  U0BAUD = 216;
}

void UART_SendByte(unsigned char byte)
{
  U0DBUF = byte;     // Send byte
  while (!(U0CSR & 0x40));  // Wait for TX to complete
  U0CSR &= ~0x40;    // Clear TX flag
}

unsigned char UART_RecvByte(void)
{
  while (!(U0CSR & 0x01));  // Wait for RX to complete
  U0CSR &= ~0x01;    // Clear RX flag
  return U0DBUF;     // Return received byte
}

void UART_SendString(unsigned char *str)
{
  while (*str != '\0') {
    UART_SendByte(*str++);
  }
}

void main(void)
{
  unsigned char name[20];
  unsigned char id[10];
  
  UART_Init();
  
  // Receive name
  UART_SendString("Please enter your name: ");
  for (int i = 0; i < 20; i++) {
    name[i] = UART_RecvByte();
    if (name[i] == '\r') {  // End of input
      name[i] = '\0';
      break;
    }
  }
  
  // Receive ID
  UART_SendString("Please enter your ID: ");
  for (int i = 0; i < 10; i++) {
    id[i] = UART_RecvByte();
    if (id[i] == '\r') {  // End of input
      id[i] = '\0';
      break;
    }
  }
  
  // Send name and ID back to PC
  UART_SendString("Your name is ");
  UART_SendString(name);
  UART_SendString(", and your ID is ");
  UART_SendString(id);
}

这段代码会先向PC发送提示信息，让用户输入姓名和学号，然后通过串口接收用户的输入，并向PC发送包含姓名和学号的信息。可以使用串口助手等工具进行测试。
