il post you an apm if you want to give it a go?

i tried compiling for a 32u but there are errors that i lack the skills to fix.

Mike I have been thinking about how to integrate your arduino making converter into apm and I got thinking about the 32u that's on the apm as a usb:serial and ppm encoder. On most apms the ppm encoder can bypassed by soldering a jumper pad on the bottom freeing it up. So my thought was if i could lo...

On the topic of baud settings, I thought I would add this special note for anyone considering using the 3.3V Arduino Pro Mini instead of the 5V version. I didn't see any reference to the 3.3V version elsewhere on this thread, so I gather most are using 5V. I needed to use the 3.3V version because I...

Mavlink cannot be used over frsky rc.

You would have to use an UHF system that supports it like Openlrs, dragonlink v3 or tbs crossfire.

I haven't tested your latest code but people are saying it's not working. http://www.rcgroups.com/forums/showthre ... st35842653

How did you test the raw output if the adapter?

I've done another commit, this one should return a RSSI value, when operating in the Tx. I can't test it though as I don't have anything that will send an RSSI value! Mike. if its just apm you are using for testing then just enable the rssi pin and connect it to either ground or 5v to test 0 and 10...

MikeB wrote:At the moment it doesn't. I could probably pick up a RSSI value from a Mavlink message (I recently did that for native Mavlink) and send it out.

Mike.

that would be ideal,

I've just committed the updated sources to Github. There is a new mode, enabled by connecting IO6 to ground, when in SPort mode. With this, then the SPort output will send the 'polling' bytes as well as the data bytes, and not require polling. Mike. excellent news! I will try it as soon as I can. h...

i have built a 3dr radio module into a jr module along with the telemetry adapters and bluetooth so it gets frsky telemetry via the 433 3dr radios.

the problem with mavlink support on opentx is the code has not changed since the 9x so you cant use any of the mavlink data for alarms or alerts like you can with frsky. the poller inject a fake rssi and swr so the taranis will accept the telemetry. i think your adapter is also putting out rssi so i...

i have managed to get your converter between the openlrs and taranis working by connecting another arduino up and getting it to do the polling. i used this running in parallel on the s.port wire http://www.rcgroups.com/forums/showthread.php?t=2245978 im sure you could do the polling on your converte...

ah ok, it would be far more flexable if you put the polling functionally into the mavlink>frsky converter. I currently use your adapters with frsky on opentx 2.1.8 and just name the values manually but i would really like to use it with openlrs or 3dr radios just having the adapter on the ground sid...

are you running
mavlink>converter>rx>tx>handset?

or mavlink>rx>tx>converter>handset?

I found this and I see they have added polling to the library and to get it to show on taranis they are just inserting a fake rssi. if you added this to your arduino board as an option then it would be able to run either air or ground side and inject rc rssi from the apm instead. http://www.rcgroups...

I think so. For information, the sensors showing just as numbers are as follows: HOME_DIR 0xA HOME_DIST 0xB CPU_LOAD 0xC GPS_HDOP 0xD WP_NUM 0xE WP_BEARING 0xF BASEMODE 0x1D WP_DIST 0x1E HEALTH 0x1F STATUS_MSG 0x20 Mike. im using your adapter with opentx on a taranis and i was wondering if you coul...

what version of opentx are you using to get telemetry with xjt? as far as i knew it only worked with er9x.

no you missunderstand, you only click it once and it will always put out telemetry without having mission planner connected, its the same procedure if your using a minimosd.

to get ardupilot to spew data all the time you have to click the enable osd button in mission planner.

i have been trying to do that your way for years now but i have just never found a way of getting it to accept raw frsky (untill now)

Mike what would be ideal is a Mavlink to frsky adapter that puts out framed frsky like a djt, so it can sit between the openlrs and any frsky capable handset either opentx or er9x. this is the only project i have seen that puts frsky telemetry directly into the handset, if that could be grafted onto...

MikeB wrote:The FrSky SPort to UART units have a limited transfer rate. When operating in bi-directional mode the maximum is 90 bytes/second.

Mike.

yea i seen that, i ordered a pair anyway for testing,

on a side note, I have been looking to replicate this setup on 2.4ghz for a long time now and recently came across these FrSky S.Port to UART converters. http://www.frsky-rc.com/download/view.php?sort=Manual&down=156&file=S.Port%20to%20UART%20Converter from what I can work out it should allo...

What firmware are you using (or what firmware did you port fro the SKY board)? Mavlink isn't supported directly on ersky9x at present so I'm very curious about this. Even using a ttl level modified DJT, the only hardware change needed on the 9XR-PRO is the wire from J8 pin TX1 to the 'C' pad to get...

you are correct in that it would stop operation with sport xjt, i use a modified djt with ttl mod so that i can swap between openlrs and frsky telemetry by just changing modules since both are on ttl levels. The 9XR-PRO was designed to support both inverted RS2323 levels and inverted or non-inverte...

you are correct in that it would stop operation with sport xjt, i use a modified djt with ttl mod so that i can swap between openlrs and frsky telemetry by just changing modules since both are on ttl levels. this could be improved by connecting the openlrs mod to com2 but i could never it it to work...

I have been through er9x and and mavlink and it just doesn't work I don't think the mavlink code had been changed in years so it showed very little info and none of the flight modes were accurate. I used to use opentx-mavlink on my 9x and 9xr bit it was limited to mavlink only. The version I'm using...
