i have two questions which hopefully somebody can answer:
- If i have a PC and a TG9x with the ER9x- Ardupilot Firmware, is it possible to connect both the PC (Mission Planner) as well as the Remote Control (TG9x) to the Ardupilot at the same time ?
-> E.g. by running a Cable from the TG9x to the PC and using the same modem ? - In other words, can mavlink be used multipoint ? - Or is it only point to point ? - If so, how would i wire TX and RX ?
- Is there a software version for the ER9x which supports also rolling switches ? - I have tried the normal ER9x, but it seems not to support e.g. to use the TRN switch as rolling switch like the SW version from GerardV. - Anyone got an idea ?
I would really highly appreciate an answer on this.
The source code is here on git : http://code.google.com/p/gv9x/source/checkout
But I think ATmega640 is not limited to an interresting project, but we can only keep the functionality rollout switch. TH9X crashes easily if the program is a bit big.
But to work with mavlink we can have an alternative:
1) the purchase of the card gruvin9x for ATmega2560
2) use the PC with Misson Planer
3) use the Android device.
I like the third, because it is small and powerful enough to bring on the field, but right now I'm a bit busy to work 100% on the project.
But I can help you if this is in my rope.
using Android sound quite nice - i also have an Android phone to use, but for me having it in the remote would be best. - I have actually added a Jeti Display (Jeti Box Mini) and a Jeti Box to my Transmitter already + i eventually have a computer when flying - so adding android would be a 5th display.
When you say it is crashing, do you mean the software for the TH9x gets too big for the Atmega 64 ?
Maybe, i could quickly just resolder a Atmega 128 into the existing PCB or get the Gruvin 9x board. Can your software just be built to the Gruvin / 2560 by changing the makefile ? - Or would i need to change a lot in the actual code ?
Attached you can find a picture of my transmitter. If i add an android phone, i guess, i would need a extra weight to balance..
I have also a Frsky with FLD02, it is good for having RSSI, too much technology for a little UAV :)
When coding a functionnality, we must always trying to optimize memory space or it is too diffcult to have great array. The symptoms when it crash, TH9X reboot and returns to the first menu. Test many times new functionnality before flight.
Just for information: 57 kbps with XBee works with ER9x - i had set the sysid wrong. Other than this, everything is really fine. - I have seen some lockup conditions, but may look at fixing these in the next days.
Has anyone tried this (point-to-multi-point) using the new 3DR Radio Telemetry Kit (air module in both the aircraft and the ER9x with the USB ground unit on the PC)? It would be a HUGE advantage to have the MAVLink telemetry available in both places.
can u help me please ....i dont know how to connect 3DR Radio with my er9x transmitter ...if you have any photo it ll be very helpfoul..thank you
Here is the first confirmation I've heard that is is indeed possible to hookup a 3DR radio to a 9x for telemetry: http://diydrones.com/xn/detail/705844:Comment:1036115
tell me please
i put arducopter firmware to er9x with classical connection ...and then i ll make the connections to 3dr radio ??
or never mind what i can do first ??
is this the same connetcion ?
sorry for my English
