First of all I have to say that I'm completely new to the RC world.
Today I just finish assembling an quadcopter kit from jDrones. I loaded the latest firmware onto the APM 1 and everything seems to be working fine, but when I try to setup for the first time in the Radio Calibration page, when I move the sticks on my turnigy 9x, nothing happen. I saw that the bars on the wiki page ( what it is suppose to be) is green, but on mine, it's blue. I'm not quite sure what I'm missing here because I've never done this before, but I think I've followed the instruction correctly.
Is there anything extra that I'm suppose to do to make the Turnigy 9X (stock) work with APM1?
Some extra observations:
Does anybody have an idea about what I could possibly miss or what newbies often miss?
Let me know if you need more information.
Harin, can you please check if you have small jumper soldered on bottom of the CPU board. There is an small 3 pad solder jumper that needs to be soldered on correct position (name I/O PPM). If that is not soldered. Make a small solder blob between center and PPM side.
If you are missing it, looks like our engineer forget to solder that for you. After that you should have proper signaling coming to Mission Planner
I found the 3 pad solder jumper and it was not solder! I will probably solder it this evening and come back to update if it works yet. Thanks.
ps. your engineer probably forgot to solder the SJ1 jumper also. At first the battery won't power up the APM but USB will. Luckily I found that out in the troubleshoot section in the wiki!
ok good to know, i will remind them to check that more carefully as both of them should be soldered as default.
Yes if you are missing that I/O solder. You will not get any input to MP so that was your problem.
Maybe someone should add this to the troubleshooting guide to prevent unlucky newbies like me from being throw off balance!
yes we will add it to wiki too
Harin, maybe you could answer... Where do I find this jumper and how do i solder it? Thanks. I have the same problem.
Please explain me where to find this jumper, because i'm having the same problem. Maybe a photo? Thank you.
In my limited experience I've noticed that as I increase throttle the blue led flashes faster. It's possible you will need to "reverse" the throttle control in the 9X. APM will not arm at any throttle setting other than low/off. Also rudder/yaw channel must be set to full 100% range (i.e. you can not be in a lower dual rate rudder setting) when attempting to arm the apm.
Tom, flashing behavior really depends on the software version that is inside PPM encoder. On Harin's case there were missing jumper between PPM encoder and main processor. On custom jDrones electronics there is extra jumper to handle PPM sumcodes. This is for people who want to connect their receiver directly to main processor.
Hello, di you solve this problem? I am having the same.
