Re: T9x FrSky telemetry mod fail. Gibberish filled/blank scr

A serious question is: If you purchase another Tx, what about the 9XR-PRO? You may not like the ergonomics of this, but it is $100 instead of $60. This requires NO mods to use with a FrSky DJT (or XJT). The DJT needs an external cable to connect the telemetry (or an internal to the DJT wiring mod),...

Re: T9x FrSky telemetry mod fail. Gibberish filled/blank scr

This time around I'd like to take the safest route to doing the mods even if it costs a bit more. What do you guys recommend? Using the smartie parts? Level converters? I see so many different tutorials around its a bit overwhelming.

Re: T9x FrSky telemetry mod fail. Gibberish filled/blank scr

Something that you might not have done and just came to my mind.. Please go to the general settings, scroll down to hardware and set the option "Frsky Mod Done" to on. João Too late now :/ The RC God's must hate me or something. After I removed some hot glue on my DJT module I guess I moved one of ...

Re: T9x FrSky telemetry mod fail. Gibberish filled/blank scr

Here are some pictures of the board. I removed the 6 cables that were used to flash the board for some better real estate and easier troubleshooting (I've already flashed er9x-frsky). In the picture it may appear that the solder from pin 3 and the resistor right under it are connected but they're no...

Re: T9x FrSky telemetry mod fail. Gibberish filled/blank scr

So I ended up buying a new T9X and decided to give the mod another shot. Everything seemed to go well this time, I even completed the backlight mod too. However now I have 1 NEW problem. The old problem of the screen freezing then going out seems to be non existent about 95% of the time. Sometimes i...

Re: T9x FrSky telemetry mod fail. Gibberish filled/blank scr

You could try cooling the M64. Run the Tx until the display just starts to go wrong, then try making the M64 centre a bit damp, using a damp finger. The evaporation of the damp cools the chip a bit. See if the display comes back OK for a while. Keep the M64 slightly damp to keep it cooling. Mike. W...

Ah, yeah you're right! I just verified and it is supplying 3.3v to the lcd. I'm so convinced it's the mega64

Re: T9x FrSky telemetry mod fail. Gibberish filled/blank scr

I would check the connections between the processor and the LCD. Because the processor runs at 5 volts, and the LCD at 3.3, every connection has a 5K1 and a 10K resistor in it. The 8 data lines are from pins 44 to 51, the control lines are from pins 36 to 40. In particular, I'd check the connection...

Yes I used it a bit but just navigating the menus and calibrating. Used it for a good hour to so.

T9x FrSky telemetry mod fail. Gibberish filled/blank screen

So I purchased a T9X and a FrSky DJT module w/ a D8R-II Plus RX to get optimal performance out of the T9X. I did tons of research before I attempted the mod. I read guides from RCHACKER, Oscar Liang and the openWiki for the T9x, I even watched a few YouTube videos. After about a week of researching ...

Re: FrSky telemetry mod without RS232 level converter

So I followed these steps CAREFULLY and even did them all 3 different times and keep getting the same results :( I've searched DIYDrones, OPENRC forums, RCGROUPS forums, HobbyKing forums, and Google. I fee like I'm the first one with this problem. I think I might have fried my AtMega64 but I'm not s...
