Hi
I have TWR-K20D72M and I read the quick start pdf of the TWR-K20D72M .I am Freescale MQX RTOS 4.0 BSP for TWR-K20D72M.
Now I want to read the ADC value which comes from the Potentiometer Already attach to the board. So I added ADC_LDD from processor expert and set the pin no. of the potentiometer mentioned in the Manual. My settings are shown in the picture attached. then I generate the code and build bsp.
My code for reading the value is below.
LDD_TDeviceData *Analog_DeviceData;
LDD_TError Analog;
LDD_TData *Buffer_DAta;
static uint16_t value;
void Analog_task
(
uint_32 initial_data
)
{
puts("\nInitializing Analog device.....");
Analog_DeviceData = AD1_Init(NULL);
if (Analog_DeviceData == NULL) {
puts("failed");
_task_block();
}
else {
puts("done");
}
for(;;) {
//AD1_StartLoopMeasurement();
AD1_StartLoopMeasurement(&Analog_DeviceData); /* do conversion and wait for the result */
AD1_GetMeasuredValues(&Analog_DeviceData,&Buffer_DAta); /* get the result into value variable */
printf("\n - Buffer_DAta = %d Hz", &Buffer_DAta);
puts(Buffer_DAta);
}
}
But no output Shown I change the value.
Can any one suggest me the efficient way of reading the ADC values using MQX and Processor Expert.
