I noticed that the GSM library (the GSM3SoftSerial) attaches interrupts on all ports/pins of the Arduino: why on ALL of them? I can understand PINs 2&3 that are used for RX/TX, but why on all of them?
In particular I would need to attach interrupts to other PINs to do other things (such as waking up the Microprocessor at pin change), but it conflicts with the GSM interrupts. Here the code snippet from the GSM3SoftSerial that is culprit I believe:
Hi butyouyes,
by the momment we can use a workaround, Arduino GSM Shield only uses PCINT interrupts for digital pins 2 and 3, which are managed with PCINT2 interrupt (PCINT23..16, atmega328p datasheet).
What I did was to comment the rest of the interrupt routine assignenment in GSM library and comment PCINT2 vector routine assignement in SoftwareSerial library.
Currently I have arduino club in high school at the Salesian College of Duitama in Colombia.
We are working on a project that aims to integrate these weather sensors:
With this code (which requires interrupts on pin 2 or 3) http://home.comcast.net/ ~ saustin98/misc/WeatherStationADC.txt
In a connected arduino gsmshield
We want the report of the measurements will be sent to a server via the GSM shield, however because the gsm shield uses pins 2 and 3 do not know how to accomplish anemometer capture information (the sensor that requires interruptions)
Is it possible to capture information with interruptions in the same assembly arduino or this not possible?
