我在appcenter里面下载了TI ARM Compiler,可是还是报同样的错误,我该怎么做,假如这个问题不解决,新建的工程能够正常使用吗

我用的是ccs6.0,固件库和你一样,另外我添加了一个uartstdio.c这个文件就没有错误了
int main(void)
{
uint32_t ui32ADC0Value[1];
volatile uint32_t ui32TempAvg;
volatile uint32_t ui32TempValueC;
volatile uint32_t ui32TempValueF;
SysCtlClockSet(SYSCTL_SYSDIV_5|SYSCTL_USE_PLL|SYSCTL_OSC_MAIN|SYSCTL_XTAL_16MHZ);
InitConsole();
//

UARTprintf("ADC ->\n");
UARTprintf(" Type: Internal Temperature Sensor\n");
UARTprintf(" Samples: One\n");
UARTprintf(" Update Rate: 250ms\n");
UARTprintf(" Input Pin: Internal temperature sensor\n\n");
//5??,??PLL,????16M,system????? main osc?????40MHZ
SysCtlPeripheralEnable(SYSCTL_PERIPH_ADC0);
//??ADC0
ADCSequenceConfigure(ADC0_BASE, 3, ADC_TRIGGER_PROCESSOR, 0);
//We want to use ADC0, sample sequencer 1,
//we want the processor to trigger the sequence and we want to use the highest priority
//ADCSequenceStepConfigure(ADC0_BASE, 1, 0, ADC_CTL_TS);
//ADCSequenceStepConfigure(ADC0_BASE, 1, 1, ADC_CTL_TS);
// ADCSequenceStepConfigure(ADC0_BASE, 1, 2, ADC_CTL_TS);
//Configure steps 0 - 2 on sequencer 1 to sample the temperature sensor (ADC_CTL_TS).
ADCSequenceStepConfigure(ADC0_BASE,3,0,ADC_CTL_TS|ADC_CTL_IE|ADC_CTL_END);
//Sample the temperature sensor (ADC_CTL_TS) and configure the interrupt flag (ADC_CTL_IE)
//Tell the ADC logic that this is the last conversion on sequencer1 (ADC_CTL_END).
ADCSequenceEnable(ADC0_BASE, 3);
//enable ADC sequencer 1
while(1)
{
ADCIntClear(ADC0_BASE, 3);
ADCProcessorTrigger(ADC0_BASE, 3);
//trigger the ADC conversion with software
while(!ADCIntStatus(ADC0_BASE, 3, false))
{
}
//wait for the conversion to complete
ADCSequenceDataGet(ADC0_BASE, 3, ui32ADC0Value);
ui32TempAvg = ui32ADC0Value[0];
//Since 2/4 = 1/2 = 0.5, 1.5 will be rounded to 2.0 with
//the addition of 0.5. In the case of 1.0, when 0.5 is added to yield 1.5, this will be rounded
//back down to 1.0 due to the rules of integer math.?????
ui32TempValueC = (1475 - ((2475 * ui32TempAvg)) / 4096)/10;
//TEMP = 147.5 – ((75 * (VREFP – VREFN) * ADCVALUE) / 4096)
//VREFP – VREFN=3.3V
ui32TempValueF = ((ui32TempValueC * 9) + 160) / 5;
UARTprintf("Temperature = %d*C or %d*F\r\n", ui32TempValueC,
ui32TempValueF);
//F = ( C * 9)/5 +32
}
}
黄色部分是我修改的,输出的数据就和修改前不一样了输出一会后还报错了
CORTEX_M4_0: GEL Output:
Memory Map Initialization Complete
CORTEX_M4_0: Error: Timed out while waiting for target powerup/polling a hardware resource.
这个情况困惑我,为什么sequence改变后,内部温度输出就变化了,差距还挺大,还有如果一直让板子开启温度过一会儿会变大,这个应该是正常的,编译器我下载了(ti_cgt_tms470_5.2.9_windows_installer),现在是ARM5.2
非常感谢,我感觉我离成功进了一步了
//ADCSequenceStepConfigure(ADC0_BASE, 1, 0, ADC_CTL_TS);
//ADCSequenceStepConfigure(ADC0_BASE, 1, 1, ADC_CTL_TS);
// ADCSequenceStepConfigure(ADC0_BASE, 1, 2, ADC_CTL_TS);
要变为序列通道3,你第二个参数就没变。。肯定就出问题了。
第二个参数,怎么没有看明白,是哪个参数,你列的这三行,我不是把他变为注释了吗
请问一下,我研究生要专门搞嵌入式,但是本科没有学过,请教一下有什么建议,还有资料的
1.上面你的那段代码,初看没发现错误在那里,需要实际测试下才能给你回复。
2.至于办法,只能是多看,多练习,多研究了。
