[Paparazzi-devel] Re: adc_generic.c not found for target ap (Martin Muel

Hi Martin,
thanks for your help. I followed your advice, but I'm afraid, that's not
When I compile for target ap a warning comes up:

CC /home/wolfgang/paparazzi/var/easyglider/ap/modules/adcs/adc_generic.o
modules/adcs/adc_generic.c: In function `adc_generic_periodic':
modules/adcs/adc_generic.c:46: warning: implicit declaration of function
modules/adcs/adc_generic.c:46: warning: nested extern declaration of
modules/adcs/adc_generic.c:46: warning: implicit

Although only a warning, compilation is immediately aborted.
My airframe.xml specifies for communication:

<!-- Communication -->
<subsystem name="telemetry"     type="transparent">
  <param name="MODEM_BAUD"      value="B9600"/> 

Without adding adc_generic, all TM messages are transmitted normally.
The problem exists with any combination of airframe, flight_plan, telemetry
etc. settings.
Do you have an idea where to find the bug?

it is just a module now, not a subsystem any more. Can you try this:

     <load name="adc_generic.xml">
       <flag name="ADC_CHANNEL_GENERIC1" value="ADC_3"/>
       <flag name="ADC_CHANNEL_GENERIC2" value="ADC_4"/>
       <flag name="USE_ADC_3"/>
       <flag name="USE_ADC_4"/>

For some reason the USE_ADC_x has to be specified and it is not set by 
variable name/replaced in the module xml. Maybe someone can take a look.
