I am unable to compile and use Time.h library for Max32, but the same file compiles fine for my Arduino. I am using Windows 7 x86 The Time.h Library can be found at

h,t,t,p,:,/,/,w,w,w,.,a,r,d,u,i,,n,o,.,c,c,/,p,l,a,y,g,r,o,u,n,d,/,C,o,d,e,/,T,i,m,e,

(please remove all the commas)

I am using their "TimeSerial" Example.....

First I was getting an error regarding avr/pgmspace.h not found and avr/io.h not found. Then I copied all the files inside the Avr directory to ~\mpide-0022-chipkit-win-20110521-c\hardware\pic32\compiler\pic32-tools\pic32mx\include
Inside the directory avr. Now I am getting the following eroors. Please help...

First I was getting an error regarding avr/pgmspace.h not found and avr/io.h not found. Then I copied all the files inside the Avr directory to ~\mpide-0022-chipkit-win-20110521-c\hardware\pic32\compiler\pic32-tools\pic32mx\include
Inside the directory avr.

That's probably not a good idea, you should delete and reinstall the mpide distribution.

Attached is my attempt at a DateStrings.cpp port, which seems to work. The changes are probably a bit more extensive than they need to be, but I just wanted to get it working. Replace the DateStrings.cpp file in the Time library with this one and it should compile and run.

This did not work I am getting the error

C:\Users\Abhijeet\Desktop\mpide-0022-chipkit-win-20110521\hardware\pic32\libraries\Time\DateStrings.cpp:10:27: fatal error: avr/pgmspace.h: No such file or directory compilation terminated.

I downloaded fresh copy and unzipped it but still not working

Tell me the complete process. Starting from Adding the Library to MPIDE

Tell me the complete process. Starting from Adding the Library to MPIDE

The number one thing is to put ifdefs around the avr include instructions

#if defined(AVR) #include <avr/pgmspace.h> #endif

Then you can include

#include "wiring.h"

This has the necessary defines that are normally in pgmspace.h

I looked over the code briefly and this should do it. I will try to test it later

The proper place to put the library is in your local library folder

sketches->libraries

If you dont know where your sketches folder is, look in your MPIDE preferences, mine is /Arduino/sketches

This did not work I am getting the error C:\Users\Abhijeet\Desktop\mpide-0022-chipkit-win-20110521\hardware\pic32\libraries\Time\DateStrings.cpp:10:27: fatal error: avr/pgmspace.h: No such file or directory compilation terminated. I downloaded fresh copy and unzipped it but still not working

You need to replace this file with the DateStrings.cpp from the above zip file:

C:\Users\Abhijeet\Desktop\mpide-0022-chipkit-win-20110521\hardware\pic32\libraries\Time\DateStrings.cpp

The error message is saying that it's trying to include avr/pgmspace.h from line 10 of DateStrings.cpp, but my version has "#if defined(AVR)" at line 10.

I have found a major problem with the compile process. There is a file called Time.h in the pix32 includes. I am working on modifying the files so they compile properly. We have created a new github repository just for 3rd party libraries

https://github.com/chipKIT32/thirdpartylibraries

I will try to get the time library all fixed and put it up on this github site

I have found a major problem with the compile process. There is a file called Time.h in the pix32 includes.

I have several copies of "time.h" under pic32mx, but not a "Time.h"? I guess this could still cause problems under Windows. It works for me but possibly because I have the Time library installed in my personal libraries folder.

Hi davec, thanks for the DateStrings modifications. I installed it as per your instructions and the RTC example compiled and ran first time. I looked at the code but the C pointers put me off trying to change anything. We all how have a great time library for the Pic32.
