c语言如何读出字符串中的数据,如何把数据存在字符串中
怎么把数据存在字符串中？
最近写单片机一个控制程序 遇到了瓶颈，请大神指点，问题如下：
8路AD采集采集 采集到的数据存在measurement[i] 中
利用采集的数据来发送串口指令实施控制，指令格式：UartSendStr("#1P500T100\r\n")//#1P代表第一个舵机#8P代表第8个舵机、500代表转动-90度2500代表转动+90度、T100\r\n为固定字符。
AD采集中断程序如下：
void ADC0_ISR (void) interrupt 15
{
static unsigned char channel = 0; // ADC mux 通道 (0-8)
unsigned short data temp;
ADC0CN&=0xdf;
AD0INT = 0; // 清除ADC转换完成标志
//result[channel] = ADC0; // 读ADC值
temp = ADC0H;
temp = temp*256 + ADC0L;
Result[channel] = temp; // 读ADC值
channel++; // 改变通道
if (channel == 9)
{
channel = 0;
}
AMX0SL = channel; // 设置mux到下个通道
//add++;
// if(add==80)
//{
m=1;
//add=0;
// }
}
发送串口指令程序如下：
void UartSendStr(unsigned char *pStr)
{
while(*pStr != 0)
{
SBUF0 = *pStr++;
//Delay(100);
while(TI0==0);
TI0=0;
}
}
void UartSendChar(unsigned char ch)
{
SBUF0 = ch;
while(TI0==0);
TI0=0;
}
void UartCharPro(unsigned char ch)
{
//P0 = ~ch;
switch(ch)
{
case '\b': // 退格键
if(g_ucCur > CMD_TAG)
{
UartSendChar('\b');
UartSendChar(' ');
UartSendChar('\b');
if(g_ucLen)
{
g_ucLen--;
}
g_ucCur--;
}
break;
case '\r': // 回车键
UartSendChar('\r');
UartSendChar('\n');
g_ucCmd[g_ucLen] = 0;
UartSendStr(g_ucCmd);
UartSendChar('\r');
UartSendChar('\n');
UartSendChar('>');
g_ucLen = 0;
g_ucCur = 1;
break;
default: // 其它字符
UartSendChar(ch);
g_ucCur++;
if(g_ucLen
{
g_ucCmd[g_ucLen++] = ch;
}
else
{
g_ucCmd[g_ucLen] = 0;
}
}
}
void PWM_Init()
{
//UartSendStr("#1P2500T100\r\n");
delay(10000); // 延时1s
UartSendStr("#1P500T100\r\n");
//delay(10000);
}
void UART0_ISR (void) interrupt 4
{
unsigned char ch;
ch = SBUF0;
if(RI0)
{
RI0 = 0;
//UartSendChar(ch);
//P0 = ~ch;
UartCharPro(ch);
}
}
/
怎么把采集到的数据measurement[i] (数值为500-2500的整数) 存到 需要发送的 UartSendStr("#1P500T100\r\n") 指令中，求大神指点，能帮忙写出来相应代码最好！
