Subject: Re: [Paparazzi-devel] Current Sensor
Hi,
I am using a current and voltage sensor successful. First put the
following lines in firmware section:
<firmware name="fixedwing">
.
<define name="USE_ADC"/>
<define name="USE_ADC_3"/> <!-- accu voltage--> <!-- *******-->
<define name="USE_ADC_4"/> <!-- motor current-->
<define name="ADC_CHANNEL_VSUPPLY" value="ADC_3"/> <!-- *******-->
Then in Battery section:
<section name="BAT">
<define name="ADC_CHANNEL_CURRENT" value="ADC_4"/>
<define name="MilliAmpereOfAdc(adc)" value="(100*adc)"/>
<define name="VOLTAGE_ADC_A" value="0.05"/> <!-- *******-->
<define name="VOLTAGE_ADC_B" value="1"/> <!-- *******-->
<define name="VoltageOfAdc(adc)" value ="(VOLTAGE_ADC_A * adc +
VOLTAGE_ADC_B)"/> <!-- *******-->
Dont load the adc_generic module anymore.
If you don't use the voltage measurement, skip the lines marked with
<!--
*******-->
