"Warning, using attopilot with draw more than 180 can be dangerous because the power consumation grow wtih square of current :
P = I² * R
actual attopilot for 180A :
180*180*0.00025 = 8.1 watts
if you draw 272A
272*272*0.00025 = 18.4 watts"
Why not use thread as shunt ?The power module use a 0.0005 shunt resitor for a mximum of 90 amperes.If we use the thread as shunt we can measure a current more than 90 amperes.Example for 10 AWG wire with 10 cm long :The resistor for 10 AWG is ~…
"Excuse me, I try to understand what is happening.
You try to run version 2.9 on a Cirius's board.
But the difference is that Cirius use only I2C for its components, and APM2.5 use only I2C for adressing HMC5843. Release 2.9 use semaphore for SPI.If…"
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…"
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…"
My last test was on APM1 Hardware and Version 'ArduCopter V2.4.2'.Never try with ArduPlane and APM2 Hardware.The minimum configuration is only setting the data rate (air and uart) between APM and TG9X (SERIAL3_BAUD…"
"May be P5 is off.
There is no priority. In ppm mode on APM, only when ppm value change (there are 6 values) the mode change.
So if ppm value does not change and we send mavlink command code the APM mode will set with the mavlink code.
I push the 1.08 to gv9x, try it. I remove for the ppm mod the edition of the name of the control, you must chose from a list.
Try only in ppm mode there is no problem, maybe ppm value interact with mavlink command (They have worked with old…"
I never try to connect APM to PC and TG9X via the same channel (telemetry).
I just connect APM to PC (Mission Planer) via USB and TG9X via the telemetry port.
But you told of 'ER9x-ArduPilot Firmware', this firmware was not supported…"
