OpenGD77

Hello everyone, I would like to use a global variable that would be visible in all the code, do you know in which file I should define my variable? JP7NJT The code is partially modular and you don't normally expect to have variables that every single function has access to. Most variables are decla...

from what a Chinese friend told me, the firmware (119.023) of the Plus doesn't work on the normal one (he tested with an RT3S but I guess it's the same as the UV380, right?) When flashing the normal with the firmware of the Plus, the screen remains white when the normal is turned on. The friend is ...

The current theory is the upgrades made to the Plus model are largely software based. So when the Plus firmware appears: users with older non-Plus radios will be able to upgrade and gain AES 256 bit encryption. from what a Chinese friend told me, the firmware (119.023) of the Plus doesn't work on t...

Hello everyone,

Thanks for your explanation.

Regarding the sound in FM mode, I assume that it is processed directly by the HRC6000 and that there is no way to record the sound emitted and received in FM mode?

All of the interaction with the chip is in HRC6000.c Thank you for this information. I've tried the DEBUG_printf command and it works in some places in the code but not in other places. When it's not working, it doesn't display some of the information it should. Do you know what can cause this? Exa...

Hello all,

I'd like to use opengd77 as a Wireshark scanner.
Do you know in which part of the source code I can get a TX buffer and an RX buffer that contains the entire Data Link Layer (Layer2) and another that contains the entire Call Control Layer (Layer 3) for each frame or superframe ?

You can use USB_DEBUG_printf() to send debug messages to the serial port. Then view them using putty or similar.

Thank you for your reply. and is there any way to know how much RAM is left at compile time?

Hello, I have a question: with MD380tools you can do debugging with a printf("%X",something_to_print); in the source code, connect the MD380 to the computer via the USB cable and use./md380-tool dmesgtail to see the result. How do I do the same with the OpenGD77 source code? And another question: ab...

Hello all, I'm signing up because I'm trying to understand how the OpenGD77 source code works. I've used the source code of MD380Tools before, but it uses a lot of patches and you can't have full access to the hardware. I'd like to modify Opengd77 to make it a kind of frame scanner like Wireshark (t...
