You can use 3.3 from the board. I would not use a 1s LiPo as they output over 4V fully charged. |

JNJO - many thanks, all back and running!
I did find a regulator on an old gyro and thought I'd try and remove and reuse. But given the size, my rig's not god enough to hold, tweezer and remove. So went for the 3.3v route. Now, just need to get the PID right. Thanks for the help. |

Hello friends ... I am writing from Argentina. I bought one of these boards from HK, and I'm doing the first tests on my tricopter (Turnigy Talon Tricopter). In one of the last tests were burned one of the engines, for which I am taking the opportunity to review everything and add some accessories while waiting for the new engine.
So much was going well, but today I trying to connect my accessory caddisfly BT to communicate with my laptop or cell phone and I have failed. The accessory I bought is this http://www.goodluckbuy.com/crius-mwc...-adapter-.html The BT I connected to the serial port 0, and when I try to connect with my laptop or cell phone, the BT light is solid red, but I can not read any data from my board. COM ports on my laptop, are selected, and the linkage also my phone is done, however failed to get any data (PIDS, Aux, real time reading). I wish I could advise on that I can be doing wrong, and need to know if it is necessary to set a parameter from Arduino to the BT work. And finally, I wonder if there is any possibility to connect the BT Serial port 1, or only possible connection on port 0. From already thank you very much and congratulations for all the contributions they make to this community ...!! regards Marcelo |

Very well worded post for a non-native English speaker. I'm no expert as I've never done telemetry with this board, (yet), but to my knowedge you would have to uncomment the TM line in the config.h file (within the Aurduino environment) and reflash. This would route the TM data stream to the serial port. Without this, the BT link has nothing to transmit. One of the other experts (Majik for instance), will chime in with an answer.

Visit this link to give you an idea of how BT should work with an Atmega 2560 board if the BT module is properly configured and paired to the receiver.

Did you got already some infor about what is new on 2.2 ? Does this include the improved baro and alt-hold that was worked since months by a guy on the multiwii forum --------- EDIT some changes: - baro Alt from mahowik - baro calibration and some baro mods from Sebbi - new task scheduler for a better computation time repartition - better Ublox code detection - HORIZON mode (mix between ACRO & ANGLE) - ANGLE mode is the old LEVEL mode - every UART for everything on MEGA - cool GUI enhancement from magnetron - spektrum bind button for spektrum receiver (Danal) - telemetry cosmetic - bug correction for servos on MEGA - failsafe is more robust - variometer from Hamburger - mag gain calibration improvement for HMC5883L from EOSBandi - GPS MKT binary parser from EOSBandi - GPS forward predictive filter from EOSBandi - follow me option works now in GPS HOME&HOLD mode via a ezio app - RSSI added - reconnect button in gui (uart speed can be changed in the file .txt) - IMU optimization |
