Part Number: MSP432P401R
Other Parts Discussed in Thread: ENERGIA
Hi,
I was working through some of the the MultiTasking examples in Energia for the MSP432 and I ran into a compile error when trying to run the MultiAnalogInput example.
The version I am running is Energia 18 aka Energia 1.6.10E18 on MacOSX 10.9.5, however the version listed in the Library folder is Energia15. (??)
This is part of the error output I get:
Energia15/packages/energia/hardware/msp432/3.8.0/system" "-I/Users/jonnymo/Library/Energia15/packages/energia/hardware/msp432/3.8.0/cores/msp432" "-I/Users/jonnymo/Library/Energia15/packages/energia/hardware/msp432/3.8.0/variants/MSP_EXP432P401R" "/var/folders/kd/nz4bt2g1255fncpc9bj8pgnh0000gn/T/build2ea6ebefa65a20ff18809c7e85905d34.tmp/sketch/MultiAnalogInput.ino.cpp" -o "/var/folders/kd/nz4bt2g1255fncpc9bj8pgnh0000gn/T/build2ea6ebefa65a20ff18809c7e85905d34.tmp/sketch/MultiAnalogInput.ino.cpp.o"

Analog2:7: error: 'sensorValue' was not declared in this scope
sensorValue = analogRead(sensorPin);
^
Analog2:7: error: 'sensorPin' was not declared in this scope
sensorValue = analogRead(sensorPin);
^
exit status 1
'sensorValue' was not declared in this scope
To work around this, since there are shared variables, I added a MultiAnalogInput.h file (tab) with the following:
extern int sensorPin;
extern int sensorValue;
Then in MultiAnalogInput.ino I added:
#include "MultiAnalogInput.h"
In Analog2 I added:
#include "MultiAnalogInput.h"
After this, the code compiled, loaded and ran without issue.
Cheers,
Jon
