I think so. That sheet answers my question, "Where does the character set come from?" For the F4 & F7, the characters all live on that OSD chip and we have to use something from there... or stay with the plain block character. So, it's like the Presidential election... no good choices. :-)

Did you make some progress, djtrance? If you need someone to test your changes, I just want to let you know that I'm in ;)

I have not time to test the changes and continue development. I hope to have time to continue tomorrow.

In other news ...
I'm going through the thread again to try to see if I can work out the connections for switches. I initiated a new thread for adding switches to the F4, mainly for my own benefit, but maybe it'll help others who want to do that too, but don't want to spend the time searching through this thread.
Also, I installed a 3-in-1 module - at least 2 out of 3 since I don't know where to connect to make the 3rd module active. I did it with wire-wrapping because it was easy and I need the nRF for the MJX hexacopter I'll use to carry the video gear. I'd appreciate any suggestions for the activating the 3rd module.


I hooked up the third module to the "GAME RX" on the trainer port. Just set the GPIO in hardware.ini to A9.

3 modules plus the original, obviously have to add all those protocols... isn't the devo.fs file getting a little too close to its limit size with all that?

I've got devo, dsm2, dsmx, v202, usbhid, ppm, hubsan4 and s-fhss protocols and about 12 models configured on my F4. And I'm using about 49kB out of 64kB. Mostly used for my micro-quads..... and Tiny Whoop!!!

Usbhid - (Joystick device) For FPVFreerider, RCDeskPilot and FMS simulators on PC. Saves me millions! Hehe..
PPM - Same, but not used after discovering usbhid! (I should remove it)

That's what I was wondering, why have both... the thing I don't like is where the USB cable comes out of, so I made myself a wireless dongle with a PPM DSMX receiver and just set up a model bound to it.

I have a couple of spare redcon CM621 dsm2 receivers lying around. I should look into this. Looks very convenient! Do I need a ppm out? It looks like I can hook up AUX4 to the mic in?

It's very easy... yes, you do need a PPM capable receiver. I just used an old OrangeRX R615x 6ch DSMX receiver, but any PPM receiver will work.

Just connect the red to positive on the USB, the black to negative, and the white to the tip of the jack plug to input the PPM signal. Then just setup a normal model on your transmitter, with the protocol of the receiver chosen, bind the receiver to the transmitter on that model, and that's it... no special setup needed or anything. I use this in PhoenixRC 5.5 and works perfect.



I have a couple of those DSM2 receivers you mention, and I think they don't have PPM out, so they can't be used. One that would work and is nice and small is the micro Flysky receiver which has 8 channels via PPM here . The only thing to remember is it's not a fixed ID, so you have to bind on every startup, but the binding is the same as any of the V9xx protocol models, as in just plug it in, then turn on the transmitter, and it will automatically bind. And it's cheap. Also, being as small as it is, you might be able to fit it inside the actual dongle!!

Awesome. I think I'll try this. With smartpropo+.

I just find it so much more comfortable than having wires hanging out of the transmitter from awkward places... I hate excessive and unnecessary wires all over the place.

Doesn't need an external power source even as it feeds straight off the 5V the USB gives.

Where is that located in the tx? I'd like to make the connection, but don't know how to find it from your description.

If that's from banggood, I think their doc is wrong; pretty sure it's copied from one of the higher-spec redcon RXs, and that there's no PPM-out on the CM621 (well, it doesn't have an AUX4 for starters...)

GAME_RX is the bottom pin on the trainer port... the problem is i don't know if it can be used if you are using an arduino for PPM in as it's the same port...

I've just been looking at the schematics of the F4, and A11 seems to be USB D- and A12 is USB D+... now, you wouldn't be using the module and the USB port at the same time, so, would it work if you wired it into there, assigned the A port in the hardware.ini, and just fitted a small switch on that particular line, so when you are using the USB port, you can disconnect the module connection via the switch? I mean, you would only be using the USB port when using USBHID or in USB Drive mode.

If not, then A2 isn't doing anything... would it work for this? It would mean soldering directly onto the MCU, but...



If you want to try it, A2 is the first pin on the MCU on the top right corner on the right hand side, marked here in red. I mean, I don't know if assigning a port to a module is as easy and simple as this, but it might be a way...

OK, Quick update...

I tried it out with my nRF24L01 module I had installed in A13. I just removed the solder point from there and soldered it to the first pin of the MCU I painted in red, then changed the Hardware.ini file to A2... AND IT WORKS PERFECT!!

And, seeing as it's the end pin of the MCU, it's very easy to solder to without "slipping" to the adjacent pin or anything!!

And I have no way of actually verifying this as I don't have one, but based on internal photos, and the schematics for it, this will probably work on the F7 too

Where is the trainer port? I see the socket for connecting the DSC plug from the back half of the case, and I see a "GAME_TX" label on the board next to it, but not finding "GAME_RX". I do have a question (see next post) about your other approach.

Ok.
If I used this method and
if I had this particular module selected and
If I turned on the tx in USB mode without a switch turning off the module ...
What would happen?
I think nothing bad would happen because by starting in USB mode, the startup routine would not read the hardware.ini file and that means the modules would not be recognized or initialized - thus, no conflict.
What do you think? :)
