GPS/GPRS/GSM v3 Digital Pins conflicts
diannawills 2014-03-09 15:52:43 9353 Views19 Replies Hi,
Here's the brief problem:
I have Romeo v2 R3 and the PWM is using:
Digital Pin 4,5,6,7
and the shield (GPS/GPRS/GSM) is using:
3,4,5
I read this:
Applying the Module Pin Jumpers(J10-J12) will allocate Pin 3,4,5 for driving the module. Removing the jumpers will release the above Pins, and you could connect the driver pins to the other digital pins on your board to avoid the pin conflict.
Here are the questions:
1) What are driver pins?
2) If I release Jumper J11, J12; how to I connect "driver pins" to other digital pins?
Thanks in advance.

2014-03-27 21:38:25 exactly! well.. it can drive you crazy. but its quite a nice resource. With the second serial port, you are able to do debugging seamlessly. So Serial is not conflicting and you can have the IDE serial port open as well as the Serial port the GPRS shield. The library i linked takes care of that advantage. but its not very clear to use. Let me know if you try and if its helpful. Jose

Thank you! I finally got that working. I was not aware that there's a stark difference between Uno and Romeo. Thank you for the clarification! diannawills

sorry, i forgot to add a little important note. Romeo V2 uses leonardo chipset, which has 2 hardware serials, as Grey mentioned.
Meaning you need to use Serial1 to 'talk' with the shield. We have a test code on github for leonardo based boards that might give you some ideas or help.
GPS-GPRS-GSM-Shield-V3.0
Testing manually, from the serial port, works fine. right? as instructed on the usb mode method here:

Jose 2014-03-26 22:40:59 Hey,
Romeo V2 is using Atmega32U4. It is Leonardo.
The serial port is different with Arduino UNO.
It is Serial1.
You need change the code to let Serial port to know what has been received in Serial1

Could you try this and check on Romeo v2 R3? And please try using TEL0051 v3 as well.
It does not work. I checked for the switches properly, still no output. And I tried using controlling via USB - also does not work.
I tried bypassing (bending the pins physically, with or without jumper) also doesn't work.
Basically, I am at loss how to make this work on Romeo v2. I am going to send this back to the supplier and get a refund. diannawills

Well, you can connect it to any pin you like basically.
I was not using the Analog pin, so I just connected it there, initialize the analog pin as a digital and that's it.
What are you building? Do you have any pictures of your project?
Cheers^^ Jose
