Only issue, I did use the cc2500 modue that I know it is tuned for FrSky original gears, every CC2500 has slightly different base freq ... so, with the original RX code from midelic you mah need to find the right value to intilize the freq offset ... Latest version from midelic should have auto freq tuning at binding ... but I did not test this version Anyhow ... original midelic code was working to me, and I expect the new one to work too I would need to adapt midelic code for better fit the cc2500 moduke with adapters ... I hate cabling around between cc2500 and pro mini |

ok, this will get the thread into my favorites so no more hunting through the diy page. i dusted off my old frsky prototype and only need to move a couple wires. so the theory is hold the bind button on dht and power up the rx and that led should go on? no farting around with special frequency settings? thats just one of the things that discouraged me before.
im definitely in favor of rssi too. this and ppm would be a huge advantage over low end frsky units which lack that. im not sure about the auto-bind though. in the real world instant re-link is paramount after lost signal due to interference or range issues. hopefully that is not compromised. |

No that is autotuning routine(not autobinding) it runs at binding at startup...it finds the offset value of base channel..is adjusting to Frsky original..Tx bas channel...only once at binding and is memorized to eeprom.The re-link is fast according with "e".He tested with a frsky original tx.
More difficult for tunning is the Tx module....as the rx doesn't sent any signal at binding ,,the tunning should be done manually. |

You can flash chip like any avr chip.Use a avr programmer 3USD.... like USBASP programmer...There are a lot of tutorial on the net how to flash and avr chip.Id you can buy one with 3.3V,Don't use more than 3.3V for cc2500 chip.
http://www.ebay.com/sch/i.html?_saca...grammer&_frs=1 For flashing you can use free softwares like ....avr8 burn o-mat or extreme burner.These working with USBASP programmer http://avr8-burn-o-mat.aaabbb.de/avr...de_gui_en.html http://extremeelectronics.co.in/soft...1-3-beta-test/ for more info you can search the net tutorials on how to flash avr chip with hex files. If you have aan arduino board uno or promini with arduino bootlader in...and and FTDI adaptor you can use a small program like Xloader(only for arduino boards or Atmega chips with bootloader in) http://russemotto.com/xloader/ |

Do you think you could post the source for the Frsky RX?
Id love to integrate it into a Multiwii controller like you did with the "Multiwii FlySky RX"... Great work! |

I want to do te same in the future,.....in fact frsky rx will be easier to integrate in multiiwii than flysky because of its 9ms frames update.But I'm busy right now too many projects ,,maybe one day.
Ok PM to me your email.......I'll not post it here. |

your tx and rx frsky is compatible all Modul Tx or rx from Hobbking ? ( no telemetry ) i made Modul CC2500 both TX and RX ,but still cann't connect Frsky , Tx or RX below |

The DIY TX need to be "tuned" for speak to FrSky RX ... since some CC2500 module have a different basic frequency PS: I did test only a DIY RX using Midelic code, and it did work with my FrSky TX ... |

It is compatible with Frsky 2 way...so make sure working...your Tx or RX module in is frsky 2 way mode.If your module said no telemetry that means is not compatible..is Frsky 1 way mode.
I had confirmation from independent sources that at least DIY RX is working.... |
