Seemed that there was a cable with loose contact
Thanks"

APM 2.5 Optical flow enabled weirdness
Started this discussion. Last reply by Elvis Dec 16, 2012. 1 Reply 0 Likes
I have my QAV500 platform tuned very well with 2.8.1, i can let go of sticks and have it maintain position for quite a while without any input. However, today I finally got around to enabling the…Continue

Daniel Chote replied to Daniel Chote's discussion APM 2.5 serial connectivity question"The resistor goes on rx, as rx sends a 5v signal, it reduces that. So your second diagram is correct.
Nothing changes on the APM (no bridges cut/soldered etc), on your receiver, ensure you are going in to the correct telemetry enabled…"
Oliver Roth replied to Daniel Chote's discussion APM 2.5 serial connectivity question"Thanks Daniel
But no success till now.
What do I have to do?
- Soldering some contacts? De-solder some contacts?
- how to connect the cable with tx/rx and resistor and the receiver
tx ---|
|---- resistor ---…"
Daniel Chote replied to Daniel Chote's discussion APM 2.5 serial connectivity question"No. No ground shown in my picture. This is just the tx+rx together with resistor. This is because the receiver is already grounded to the apm for power input."
Oliver Roth replied to Daniel Chote's discussion APM 2.5 serial connectivity question"Hi Captain Silver
I am really confused and I do not get APM 2.5 with HOTT Gr-24 running.
Question 1:
On Daniels picture above I do see 2 connections - one for Gnd and one for TX.But as shown in documentation (wiki) there are 3 connections on APM…"

Daniel Chote commented on Daniel Chote's blog post Alternative IDE project for compiling+uploading code"I realized last night that avrdude did not compile statically. I will fix that this morning and post a new binary"

Captain Silver replied to Daniel Chote's discussion APM 2.5 serial connectivity question"thx daniel,
just the resistor pluged - and it works!
seems important to know ......"
Daniel Chote replied to Daniel Chote's discussion APM 2.5 serial connectivity question"It is just tx+rx together (as you want to only have 1 ground to avoid ground loops), and yes... the 1.5k resistor is bridging the 2 as per documentation here: http://code.google.com/p/hott-for-ardupilot/wiki/QuickStartGuideArduCopter
Works as…"
Captain Silver replied to Daniel Chote's discussion APM 2.5 serial connectivity question"yes i still connect my reciever by SUMO. my last question belongs to the telemetry connection .... i see only two cables going out from your APM (GND and TX2) to the telemetry input of the reciever ..."
Daniel Chote replied to Daniel Chote's discussion APM 2.5 serial connectivity question"You can use PPMSum. You can follow the instructions here: http://www.mkmanual.com/graupner-mx-20
On the APM, bridge pins 2 and 3, and feed the SUMO channel on your RX to pin 1. Its pretty simple. You will need to remap channel…"
Captain Silver replied to Daniel Chote's discussion APM 2.5 serial connectivity question"for what is the RX connection, on your picture is see only two cables !?!"
Daniel Chote replied to Daniel Chote's discussion APM 2.5 serial connectivity question"No bridges requred. And yeah. You use GND, TX2 and RX2, as you have in the picture. "
Captain Silver replied to Daniel Chote's discussion APM 2.5 serial connectivity question"yes, but the wiki assumes that there is a APM2.0 and I have a APM2.5 where the layout is different, ie the connections of the PINs. But you have also the APM 2.5!?
Can you please tell me what connections and bridge you've set? . Are the Pins TX…"

I finally rebuilt my ATG-700-AL Hexacopter, and got around to moving my QAV500 over to the Graupner receiver. Now that both platforms were functional, I decided to get stuck in to 2.9 and hott-for-ardupilot. …

With the 3DR black friday deals, and the release of their power module, I took the opportunity to get another couple of APM2.5s, the cases that we have been anticipating, and some power modules. I got it all assembled yesterday and I must admit I love the simplicity it adds to the build.
I now just have signal leads coming from the ESCs in…
