[Tinyos-help] ADC&MDA300

[Antonio Prados Vilchez]

Hi TinyOS users!!

I'm using a MDA300 connected to a MICAz to measure a voltage from a sensor. I want to read from an ADC channel, so I'm using this command:

call Atm128AdcSingle.getData(ATM128_ADC_SNGL_ADC0, ATM128_ADC_VREF_AVCC, ATM128_ADC_RIGHT_ADJUST, ATM128_ADC_PRESCALE);

I want to read from channel 0 with Vcc as the reference voltage. However, I always get the same data from the ADC. I've checked the sensor and it works properly, it gives variable voltages to the MDA300. 

Am I using the right command to read from the ADC?

Thanks in advance
