Hi everybody,
I am trying to adquire data from the mma7260 accelerometer from the shimmer
platform. My code is this:
#include "printf.h"
module Accel2P{
provides interface AdcConfigure<const msp430adc12_channel_config_t *> as
AdcConfigure;
uses{
interface Boot;
interface Leds;
interface Init as Mma7260Init;
interface Mma7260;
interface Timer<TMilli> as Timer;
interface Read<uint16_t> as AdcRead;
}
}
implementation{
const msp430adc12_channel_config_t conf = {
inch : INPUT_CHANNEL_A5,
sref : REFERENCE_VREFplus_AVss,
ref2_5v : REFVOLT_LEVEL_NONE,
adc12ssel : SHT_SOURCE_SMCLK,
adc12div : SHT_CLOCK_DIV_1,
sht : SAMPLE_HOLD_4_CYCLES,
sampcon_ssel : SAMPCON_SOURCE_ACLK,
sampcon_id : SAMPCON_CLOCK_DIV_1,
};
event void Boot.booted(){
call Timer.startPeriodic(512);
}
event void Timer.fired(){
call Mma7260.setSensitivity(RANGE_1_5G);
call Mma7260.wake(TRUE);
call AdcRead.read();
}
event void AdcRead.readDone(error_t result, uint16_t val){
printf("%u\n", val);
printfflush();
call Leds.led2Toggle();
}
async command const msp430adc12_channel_config_t*
AdcConfigure.getConfiguration(){
return(&conf);
}
}
I am trying to adquire data from the X-axis of the accelerometer (Channel
A5), but what is displayed is not any correct value. I don't know if I am
doing something bad...
Could somebody help me??
Thank you very much!
