Hello everyone
I've started to notice this message appearing with our (Bare Conductive's) HID keyboard examples for the Atmega32u4 based Touch Board when compiled using hourly builds (currently 2015/10/09 12:13). Looking at things, this seems to be being triggered because the Keyboard and Mouse functions are out of scope at compile time. What has changed in the build recipe to cause this? Our hardware plugin is available online at https://github.com/BareConductive/bare-conductive-arduino - has the boards.txt requirement changed recently?
In a broader sense, is this a risk for everyone out there with 32u4 based boards? What can we do to maintain Keyboard / Mouse functionality across these?
Sorry if this is already covered elsewhere, I couldn't find anything.

Hi Stefan,
may you try to add #include <Mouse.h> or #include <Keyboard.h> on the
sketch?
The error is probably due to a revamp of the USBDevice on the mega32u4
core that is currently in progress, adding the include above should fix
the problem.

This sorts it out Cristian - is this something we will need in the long run or should I just leave it as it is and assume this will be fixed by the time that 1.6.6 is released?

Hi Stefan,
adding "Mouse.h" or "Keyboard.h" will remain compulsory also after 1.6.6 release, because it is part of USB core refactor and will help having more powerful sketches, occupying resources only if really necessary.
The error message instead will be greatly improved and will tell to add the right "include" rather than showing cryptic messages about Leonardo (which where wrong also before 1.6.6, btw :D )
An out of date but useful howto can be found here (https://github.com/arduino/Arduino/wiki/PluggableUSB-and-PluggableHID-howto).
Bye,
M

Thanks for this. Something like this should work fine then, right?
#if ARDUINO >= 166
#include <Keyboard.h>
#endif
The ARDUINO compile time version define still exists right? BTW, which file is this in - I can't find it at all searching the repo!

For anyone still playing along, seems that the Arduino define (done in the compiler recipe with a -D parameter) is now in the format 10606 for 1.6.6, as opposed to 166 as it would have been before. Is this a permanent change?

Yes. 1.6.6 -> 1.06.06 -> 10606
its a smarter formatStefan Dzisiewski-Smith

Good stuff - and backward compatible for > compares too :)

hi
is any one working with ACS 712 current measurement module with arduino.
i saw some emote on http://www.instructables.com/id/How-to-Measure-AC-Current-using-Hall-Effect-Sensor/?ALLSTEPS which uses the differential amplifier after the module .
i want to konw , we should use the differential ckt or no/?
currently i didnt used the ckt and use the module alone and i have the 2.68 v permanently even after the load connection .
i check the module with the magnet and its respond proper
any suggestion appreciated
regards

Hi there
Your question isn't in the best place to get answers - this is a mailing list for those working on developing the Arduino platform itself or other intersecting technologies.
For project assistance I would start with the Arduino Forum (http://forum.arduino.cc/) or Stackexchange (http://arduino.stackexchange.com/).
All the best
Stefan
