Hello everyone,
I am working with the MSP430F2617 microcontroller and CC2420 radio. I'm
using Zolertia driver.
I have written an application that sends temperature readings every 2
seconds microcontroller to a base station (BaseStation Application). The
readings are consistent and depending if you use the power of two batteries
or USB power values are different but them are apparently valid.
The configuration selected in the case of temperature is:
msp430adc12_channel_config_t adcconfig = {
inch: TEMPERATURE_DIODE_CHANNEL,
SREF: REFERENCE_AVcc_AVss,
ref2_5v: REFVOLT_LEVEL_1_5,
adc12ssel: SHT_SOURCE_ACLK,
adc12div: SHT_CLOCK_DIV_1,
sht: SAMPLE_HOLD_4_CYCLES,
sampcon_ssel: SAMPCON_SOURCE_SMCLK,
sampcon_id: SAMPCON_CLOCK_DIV_1
};
Now, I want to read the internal voltage of the microcontroller, but always
gives OFFF reading if I use both batteries (2.6 V) or with USB power (3.3V)
and I do not know the error Could someone help me?
The code used in the case of voltage is:
TestAdcC.nc
#include "Timer.h"
#include "TestAdc.h"
module TestAdcC
{
uses interface Boot;
uses interface Leds;
uses interface Timer<TMilli> as Timer0;

uses interface Msp430Adc12SingleChannel as adc;
uses interface Resource;
uses interface SplitControl as Control;
uses interface Packet;
uses interface AMSend;
}
