http://arduiniana.org/libraries/NewSoftSerial/ Here is an example for GPS to use it: http://www.ladyada.net/make/gpsshield/download.html The at2so on-drone app can mark down the GPS position when received Takeoff AT comamnd "AT*REF=1,290718208\r", and make Auto-Return in case of out of control from RC (e.g.: out of range). |

That would be a nice feature, you could just turn off your transmitter and it would come back home! |

I just made a cable, that brings VCC, GND, TX and RX from the serial interface to the board, this way I did not need to solder in more sticks. If you look at the pictures of my previous post, you'll see I put a 4 position header on (RAW,GND,RST,VCC), this is where VCC and GND from the programmer go, TX and RX go to the other header. This setup does not have an auto-reset when you download, so you start the download and press reset on the board until the Arduino IDE shows the message that it has compiled the sketch, it will download right after that.

Arduino IDE
Okay. Its my first time using this IDE.
1. I launched the IDE. Make sure to choose Tool>Board>Arduino Pro Mini 5V..328 2. From the menu, I click on Sketch>Add File> 3. The choose file "rx2at.c" 4. Then from menu. I click on Sketch>Verify/Complie 5. Once complied, I click File>Upload to Board I am hoping this is right and I choose the right file "rx2at.c" from the dr003 folder. Thanks |

Error
I am getting this error when I try to upload.
Binary sketch size: 11236 bytes (of a 30720 byte maximum) avrdude: stk500_recv(): programmer is not responding avrdude: stk500_recv(): programmer is not responding P/s-I am using a MacBook Pro Could it be that my programmer is not showing in the Serial Port menu. Only see bluetooth items on there. |

Hello,
i'm on MAC as well... As a serial interface, i use a FTDI Breakout 5V Sparkfun : http://www.sparkfun.com/products/9716 On arduino IDE, it appears as : Tools -> Serial Port => /dev/tty.usbserial-A700eDIY The driver for this serial interface, as long as it is based on a FTDI is given with the Arduino IDE... The one i use is : FTDIUSBSerialDriver_v2_2_16.dmg Pick it up here : http://dl.dropbox.com/u/2463308/FTDI...er_v2_2_16.dmg It should work better... Cheers. Laurent D |

Yes. I always check on a new setup each side which wire has a voltage, it is the transmitter and needs to go to the one without voltage on the other side...

Loaded
Nice, it recognized the usb unit and loaded the firmware.
Without anything connected to the arduino, I have the red led on and green led blinking. |

setup file
miru,
I was reading the that file earlier. It was asking to upload rxat.c file. Should I do upload that to the arduino first to make sure all the commands are doing the right thing? Once I know the radio is set right, I upload rxatp.c back into arduino. Another thing is that, I am using a Futaba 10C radio with a Spektrum module for this purpose. The rx is a clone Spektrum. Lets see how it behaves with a clone. If you have not tested other rx's, I can help test it with Futaba Fasst 6008, 6014, and other Futaba FM rx and Hitec FM rx. I pretty much have all of them. Just thought I will help out the group if you have not tested it yet. Thanks |

I would greatly appreciate it if you test your other receivers and tell the results. I don't have a Futaba nor Hitec setup, only DX7 and some older 72Mhz stuff. |
