OpenAVRc Solution (M2560) (OPENTX) (NEXTSTPRCV2.18 )


Hello word!

We are talking about a fork (with al lot of modifications) of OPENTX here.

Only used on AVR (MEGA 2560 at this time).

The goal was optimisation -> Done.
Was improvements -> Done (s)
Was translation -> Done (https://github.com/Ingwie/OpenAVRc_D...V1.15_FRAM.exe)

Was - PCB designed for "NEXT" : https://github.com/Ingwie/OpenAVRc_D..._4-10-2017.pdf

This offer A complete radio system, voice, sounds, haptic (if needed) heli, savevar, ....

All with a "POOR" processor !! (We love it because we can flight a lot of hour (days) : It just need little power & great calculation )

My first work in the DIY radio is : -> https://github.com/Ingwie/bracame-rc-radio

Little collaboration (with Franck .A) Where I've removed almost no AVR code, create screen drivers (and/or optimise), add F-ram , .....
-> https://github.com/Ingwie/NextStepRc-2.18

Now (since on year with all the NSRC TEAM (minus F.A)) : We continue the job with in a nice appelation : OpenAVRc ;-)
->https://github.com/Ingwie/OpenAVRc_Dev

If you've builded a DIY M2560 transmitter : try OpenAVRc (If you don't love it, tell us why please)

I've been testing it for a couple of days. Everything works great.

Unfortunately there is a very big shortcoming for me.
=> The buzzer does not work.

I have changed the battery range from 3v up to 16V. The reason for this is the use of 1S LiPo. Has also worked perfectly.

The project is great, I will pursue it further.

Do you use the JQ6500 option ?
If yes , what are your compiler options ?
Can you send a screen shot of the compiler tab please ?

I apologize.
I have used "OpenTX 2.1.10" so far. And I found the error. The pin for the buzzer is now 6 and not 10 as with "OpenTX 2.1.10"

Thank you, a really very good project.

A (windows) bug appear at Pierrotm777's home :

Compilation fail due to a "Cygwin bug ....." shown in the command line window.

This bug is fixed now, setup is patched : https://github.com/Ingwie/OpenAVRc_D...M.exe?raw=true

Note : Just Frsky work in the telemetry option (We will debug or remove buggy choice in next release)

Thank Pierrotm777 !

Supiiik add "multimodule" support in the firmware : (thanks a lot)

FlySky FS-i6 with OpenAVRc / OpenTX, voice, haptic and 4in1 multimodule inside (2 min 22 sec)


I just hope I"ll be able to keep his code working in the next release

We will also do a direct command to the 4 xmitters used (like deviation tx) in this next ........

Try these options when compiling. For me the choice of "NOANDSECONDS" was the problem.

Just like the screenshots are, running for me perfectly.

Thanks for this bug report :

I've tryed to find why : "NOANDSECONDS" affect only French and Spanish VOICE driver. Makefile appear to be OK .......

Well I don't understand

Could you give another try ? (This option work with VOICE but ...)

Let me propose a another try : Activate AUDIO. On the same pin (H3) connect a loudspeaker with a serial resistor & a capacitor (mini : 470 ohms & 100nF) : You will hear nice sounds when moving trims and/or configuring other sounds.

Hello,

super work with the HS1106. I've already tried it on a MEGA2560 mini Pro and it works great. I just put it together quickly.

To alarm problem. It also does not work with your proposal. I've soldered everything again, erased EEPROM and reloaded firmware. Unfortunately still No Acoustic Alarms for "Inaktiviti" and "Battery Low". Settings and inside in the pictures.

Best regards, Ivaylo.

Thank you for the SH1106 test ;-)

You use AUDIO now (with a loudspeaker + serial resistor on H3 pin ?).

I'll test here and try to find a solution (I use VOICE since more than one year and did not seen this bug).
