Hey guys,
I'm TOTALLY new to anything arduino... So i'm sorry for the probably stupid questions.
Anyway... I'm trying to compile the emonpi .ino sketch. I loaded all library's in the IDE but am getting a lot of errors shown below.
Anyway who wanna help ?
Arduino: 1.6.6 (Mac OS X), Board: "Arduino/Genuino Uno"

Re: Emonpi sketch compilation
I think your problem is "Arduino: 1.6.6"
As far as I'm aware, version 1.5 onwards of the compiler has different default settings and puts variables into different places, and that's what causes the errors that you see. The easiest solution for you is to remove that and load an older version of the Arduino IDE - possibly https://www.arduino.cc/en/Main/OldSoftwareReleases#1.0.x instead. I'm running Ubuntu Linux and use V1.0.5, which is still the recommended version for that OS.
But if you know enough C++, you can change the declarations to remove the errors. I have not checked, but there is bound to be more information about this on the Arduino forums.
Re: Emonpi sketch compilation
Allright,
That was a simple fix, thx!
However when uploading with avrdude i'm getting following error:
avrdude-original: Using autoreset DTR on GPIO Pin 7
avrdude-original: stk500_getsync(): not in sync: resp=0x43
I'm using this command:
avrdude -v -c arduino -p ATMEGA328P -P /dev/ttyAMA0 -b 38400 -U flash:w:emonPi_RFM69CW_RF12Demo_DiscreteSampling.cpp_CAL.hex
Re: Emonpi sketch compilation
OK. Sorry.
Found my problem, searching the forums.
The command was right except for the baud rate.
Thx Robert. It was one of the (many) topics you helped out with...
