ADC Temperature Sensor (temperature_sensor)

//!//! This example shows how to setup ADC0 to read the internal temperature//! sensor.//!//! NOTE: The internal temperature sensor is not calibrated.  This example//! just takes the raw temperature sensor sample and converts it using the//! equation found in the LM3S9B96 datasheet.//!//! This example uses the following peripherals and I/O signals.  You must//! review these and change as needed for your own board://! - ADC0 peripheral//!//! The following UART signals are configured only for displaying console//! messages for this example.  These are not required for operation of the//! ADC.//! - UART0 peripheral//! - GPIO Port A peripheral (for UART0 pins)//! - UART0RX - PA0//! - UART0TX - PA1//!//! This example uses the following interrupt handlers.  To use this example//! in your own application you must add these interrupt handlers to your//! vector table.//! - None.////*****************************************************************************//*****************************************************************************//// This function sets up UART0 to be used for a console to display information// as the example is running.////*****************************************************************************voidInitConsole(void)[    //    // Enable GPIO port A which is used for UART0 pins.    // TODO: change this to whichever GPIO port you are using.    //    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOB);    //    // Configure the pin muxing for UART0 functions on port A0 and A1.    // This step is not necessary if your part does not support pin muxing.    // TODO: change this to select the port/pin you are using.    //    GPIOPinConfigure(GPIO_PB0_U1RX);    GPIOPinConfigure(GPIO_PB1_U1TX);    //    // Enable UART0 so that we can configure the clock.    //    SysCtlPeripheralEnable(SYSCTL_PERIPH_UART1);    //    // Use the internal 16MHz oscillator as the UART clock source.    //    UARTClockSourceSet(UART1_BASE, UART_CLOCK_PIOSC);    //    // Select the alternate (UART) function for these pins.    // TODO: change this to select the port/pin you are using.    //    GPIOPinTypeUART(GPIO_PORTB_BASE, GPIO_PIN_0 | GPIO_PIN_1);    //    // Initialize the UART for console I/O.    //    UARTStdioConfig(1, 115200, 16000000);]int main(void)[    uint32_t ui32ADC0Value[4];    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();    //    // Display the setup on the console.    //    UARTprintf("ADC ->n");    UARTprintf("  Type: Internal Temperature Sensorn");    UARTprintf("  Samples: Onen");    UARTprintf("  Update Rate: 250msn");    UARTprintf("  Input Pin: Internal temperature sensornn");    //5分频，使用PLL，外部晶振16M，system时钟源选择 main osc。系统时钟40MHZ    SysCtlPeripheralEnable(SYSCTL_PERIPH_ADC0);    //使能ADC0    ADCSequenceConfigure(ADC0_BASE, 1, 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,1,3,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, 1);    //enable ADC sequencer 1    while(1)    [       ADCIntClear(ADC0_BASE, 1);       ADCProcessorTrigger(ADC0_BASE, 1);       //trigger the ADC conversion with software       while(!ADCIntStatus(ADC0_BASE, 1, false))       [       ]       //wait for the conversion to complete       ADCSequenceDataGet(ADC0_BASE, 1, ui32ADC0Value);       ui32TempAvg = (ui32ADC0Value[0] + ui32ADC0Value[1] + ui32ADC0Value[2] + ui32ADC0Value[3] + 2)/4;       //Since 2/4 = 1/2 = 0.5, 1.5 will be rounded to 2.0 with       //the addition of 0.5.

你硬件配置的时候接了跳帽或者连线吗，我检查了好久感觉代码没什么问题

直接把PB0/PB1/GND三者连接到u***转ttl的三个脚上面，打开串口调试工具就接收到数据了。
