problem with the usprintf
Hello, I'm currently working with some adc configuring and working with the on-chip temperature sensor of my ek LM3S6965 ev board.
My problem is with the routine I mentioned above, usprintf. The output says this:
undefined reference to `usprintf'
and the code is here:
#include "hw_types.h"
#include "debug.h"
#include "sysctl.h"
#include "diag.h"
#include "../displays/rit128x96x4.h"
#include "hw_memmap.h" //esta la agregue
#include "adc.h" //esta la agregue
#include "ustdlib.h"
int
main(void)
{
SysCtlClockSet(SYSCTL_SYSDIV_1 | SYSCTL_USE_OSC | SYSCTL_OSC_MAIN |
SYSCTL_XTAL_8MHZ);
//a partir de aqui empece a agregar el adc
unsigned long temp;
//
// Activar el clock del ADC
//
SysCtlPeripheralEnable(SYSCTL_PERIPH_ADC);
//
// Configurar el ADC para muestrear 500KSps
//
SysCtlADCSpeedSet(SYSCTL_ADCSPEED_500KSPS);
//
// Desabilitar el sample sequencer 3
//
ADCSequenceDisable(ADC_BASE, 3); //<--- solo quiero checar temperatura
// Configure sample sequence 3: processor trigger, priority = 0
//
ADCSequenceConfigure(ADC_BASE, 3, ADC_TRIGGER_PROCESSOR, 0);
//
****************************************************************************************************
****//
// Configure sample sequence 3 step 0
//
ADCSequenceStepConfigure(ADC_BASE, 3, 0, ADC_CTL_TS | ADC_CTL_END);
//Activa el sequencer 3
ADCSequenceEnable(ADC_BASE,3);
//Activa la interrupcion
ADCIntEnable(ADC_BASE, 3);
//
// Obtiene los datos del sample sequencer 3 de la FIFO
//
//ADCSequenceDataGet(ADC_BASE, 1, &ulValue);
ADCSequenceDataGet(ADC_BASE, 3, &temp);
//aqui termino de configurara ADC
//int temperatura = (int)temp;
unsigned int abc = 0x100;
char szBuffer[32];
//sprintf((char *)szBuffer, "%d", abc);
usprintf(szBuffer, "%02d", abc);
//
// Initialize the OLED display.
//
RIT128x96x4Init(1000000);
RIT128x96x4StringDraw(szBuffer, 30, 24, 15);
DiagExit(0);
}
The problem is in this line:
usprintf(szBuffer, "%02d", abc);
Can anybody help me ? I don't know what I'm doing wrong :S
