HI all!! Finally i managed to get rid of the USB cable!! Thanks to Justblair (thanks a lot Justblair)! And all the others of course. No extra software is needed!!!! All you have to do is to disable the serial console and take yourself the control of the serial port dev/ttyAMA0 (You can use minicom i...

The tx/rx pins on raspi are a hardware serial port. You can talk to it directly on ttyAMA0 if I remember correctly. I don't think you need special software. Hello Justblair!! That's interesting indeed!! Is there any project that uses the Rasp TX/RX pins instead of the USB? Tkanks for your reply!!

Arduino Mega Pin 0 (RX0) and 1 (TX0) are exactly the same in terms of signals as to what is available on the USB port. The Arduino Mega pins are 5 volt. So you will need to convert at least the TX pin to 3.3 volt for the Pi.. otherwise you can harm the Pi. No idea what software you will need on the...

My thought is: We can eliminate the extra Arduino board next to the Rasp by simply intergrate the ATmega2560 Arduino stuff with the RFlink gateway board hardware together and simply stack it as a shield to the Rasp. For convinience the serial communication of the Rasp to the ATmega of the shield sh...

Thanks for your replies folks! As the system currently is, you need a Rasp of course, an ATmega2560 board (Arduino) and the RFLink gateway board (in case you do not wish to use your own tranceiving hardware) plugged on the Arduino. So you are ending having a Rasp and an Arduino board next to it conn...

you can try to connect any ATmega2560 hardware pin to any Raspberry gpio-pin. I can guarantee you will blow up your raspberry. (something with 5V and 3.3V logic) Using a level translator is obvious, it can be included on the shield PCB!! Its not a big deal to use a translator for a virtual serial com

Hi to all here!! I was wondering why someone must connect the RFLink (the Mega2560) via the USB to the Raspberry pi and not using the Raspberry's GPIO's!!! Is there any system restrictions? I am thinking that it will be more practical to have a virtual serial interface between Rasp GPIO and Mega2560...
