SLEEP_MODE_EXT_STANDBY not declared on ATMega168

[Erik84750]

When compiling with LowPower.h using Arduino Pro Mini 168 there is still an error present. Same error was reported in July 30 2015 (issue #14).

I solved it by adding to LowPower.h the following:

#if defined (AVR_ATmega168) #define SLEEP_MODE_EXT_STANDBY SLEEP_MODE_STANDBY #endif

since you have a solution already, why not just create a pullrequest?

[Erik84750]

I am sorry!! I am new to this, I have to learn how to use Github. One additional thing I have to mention is that this relates to Atmega 168P, not the plain version.

Actually, the non-P version of the ATmega168 does not have extended power standby mode unlike the ATmega168P. If you do that, it will result in error as those bits are not present in the register. I think I would have to allow it to compile for P version only when it comes to that sleep mode and provide warning for non-P.

Thank you.

Hi rocketscream, is it possible you had added this to your low power library? When I open LowPower.h I cannot find my original addition, but it seems replaced by equivalent code?
