Hi,

Im using the Wire and SoftwareSerial in one program
and I'm unable to get run them together.

I'm using the Wire lib to read the compass modul HMC6343
works perfect....

I'm using the SoftwareSerial to read the GPS Modul MiniMod
works pefect....

BUT if I try to use these two components in one program...
NO chance. :frowning:

Did arduino (ATMEL) have any interrupt problem....?

Did anyone use the Wire (I2C) lib in combination with
the SoftwareSerial? AFSoftSerial doesn't work too.

Greetings

Works for me - we flew just that configuration on HASP this summer. The DS1307 RTC was I2C and the telemetry downlink was software serial, although the software serial was output only - no reads.

Hi,

Did you use the SoftwareSerial or the "normal" Serial port of the
arduino?
