Devo f7 for DelFly

I finally found the datasheet of the overlay ship!

* The one for the IA911 I can't upload.. So if anyone wants I can send it.

Now I'm able to specify more of what is really happening. It is in chinese(because it is some chinese cheap chip), but with google translate it is pretty easy to understand.
Maybe make an article about the devo F7 with all the datasheets and connections?

Hope to get some more working soon.
BTW. I didn't broke my capital "O" I see now... It is just missing

I'cant undertand if it is possible to do some drawing with this OSD, I has not translated all the datasheet, but I think that is possible if we write pixel to pixel.

IA911 Datasheet .
If you translate the datasheet there is nothing about how to draw pixel based. There isn't even a possibility to change the characters. So I'm not sure where you found the code?

This writes just characters on the screen.

I can explain it line by line:
1. Go through all 12 lines and set the font size to 1dt (it also supports 2dt, so yeah you can write either in a small font, 1 line, or in a big font , 2 lines)
2. This sets the size of line 5 to 2dt (bit 6 defines if it is 2 dt or 1dt)
3. This sets the character position to line 0 and row 0
4. This starts a character writing (without blinking)
5. This will write characters which are in ptr
6. This will stop writing again.

BTW. since I found the datasheet I edited the lcd driver: github.com/tudelft/deviation/blob/master.../target/devof7/lcd.c

But I currently have a lot of problems getting the tx_configure page to work.. There is something wrong with creating that menu. For example DrawTextSelect already crashes on:
"const char *str =select->ValueCB(obj, 0, select->cb_data);", so really strange

That is normally how a character display works, except this chip doesn't has the possibility to change the characters

do you think that is necessary to buy a new serial flash to test it your firmware?
I have my F7 with the stock memory... but you an PB are ussing more memory. I don't know how I can help you with my stock radio...

Happy new year everyone

I'm almost 100% sure you will need new flash memory to be able to use the firmware correctly. Maybe some features will work, but I'm not sure.

Today I fixed a simple emulator for the Devo F7, implemented the text based LCD in a nicer way and switched to mercurial for the easy conversion to the original deviation project. My new repository is: https://bitbucket.org/fvtienen/deviation

The emulator is almost 1on1 with the original Devo F7, but there need to be done a lot in the GUI to get it all working. So maybe someone can take a look and help a bit with some parts, because I'm not that experienced with deviation. For example the crashes when you go to certain screens etc. (This is also on the real transmitter)

Happy new year!!!
Can I use any flash memory?, or it's needed to be a specific model?. for example I can use a 32 mb of flash memory?
I will try to install the toolchain and the emulator, for testing

I have now the emulator for devo F7 on my computer, but sorry, I don't know how I can change the menu after de rebot, apear deviation -> Model 1. and I don't know how I can change it to anther part of the menu. I will search the documentation, but can help me if you can send me the link or more information.

Thanks for your answer, I will buy it the same memory.
can you give me the url for the tutorial to move into the simulator for devo 10 (I think is the same like the defo f7). I need it because I don't know how I can change the menu into the devo f7 emulator
Thanks PB.

Thanks, now I can test it with the emu_devof7

this is my review with the emu_devoF7

First step.
When the emu start, only show in the screen Model1.
I think that this is because there are not any icon or information in the first screen.
When I enter to the Main menu, I think that is better if you put something like "*" or "-" in the end of the field, because is more easy to understand what field are you market.
when I enter to the Model menu I have the first problem, I guess
1.- the emu, is only showing "Model menu" in the screen, nothing else.

2.- in the "transmitter menu" when I tried to enter to the "trasmitter config" the emu has failed
3.- in the "channel monitor" only is showing something like "channel output 1 - > "

into the telemetry monitor don't show a real information but the menu, I think is working well like first step.
Is showing "Temp -> 1 2 3 4 " but without information
4.- in the usb menu only show "USB" without settings


I will try to understand how this port is working and after this maybe I can help you to fix it the problems there are into the menu or some functions

Yes these are known problems

The remark about the * or - is different in the emulator then on the real device. There you will see the text blink that you selected, instead of not showing up in the simulator. But this was the easiest way to test some stuff in the emulator. I like the blinking for the selected items ont he device itself, but yeah will take a look if that is sufficient.
