Volantex V761-1 Firestar Mini protocol

Thank you !!

I will use the code and upload to my multi-module in taranis(only real option for now).
still need to decide on new jumper or not....still pissed it is gone
should be able to get is done tomorrow , then report back

Many thx !!

I'm done with the port to multi-protocol( based on pascals project)
https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/compare/master...KillSwitch422:V761

My coding skills are seriously rusty, so would be good to review, that and this is my first attempt at git-hub and fork and and and
I will try update my module tonight and test, might need to wait for a day or so to get out to field to do flight tests.

first test no joy, having a second go with some changes.
there is no successfully bind and tx seems to continue the bind attempt indefinitely( displays "binding" and gives the bind "chirp")

Its alive!!!
I have all 3 channels and gyro function
latest commit
github.com/pascallanger/DIY-Multiprotoco.....KillSwitch422:V761

massive thanks to you!

was missing the BIND_DONE command
and the initial send packets was changed from if( bind) to if (phase != V761_DATA)
also reshuffled the gyro setup to before packet was send
and bind period set to return 50( in place of 15730)

Please let me know once you have a Deviation compatible transmitter so you can check if my code is working before merging it

Will let you know.

Hope some more can test this that we can get additional TXID and the frequency hops

But if it works like that ....

I must say I'm not sure what the exact implication is.( the next phase of my learning curve will be to start understanding the code better rather that copy from examples)
Although the bind is achieved must sooner on the Taranis that with the stock one.

ok thanks, I think there is a change at rx end, but will need to do test flight first,
I suspect there is a max roll and pitch that is set in beginner mode, with the stock tx, I cannot loop in beginner, but I can in midd

edit: constrain rf_channels to 0x00 - 0x50, higher frequencies don't always work well when emulating the xn297 with the nrf24.

I plan to test this as soon as possible , first I want to get my STM32 version module setup with the code before I start to play again on the PCB one.
that and my wings are clipped due to other priorities for about a week.

I know it's still WIP but I looked at the code. I see a couple of things:
- bind_counter could become negative but should not. So I advice to protect it by replacing bind_counter-- with if(bind_counter) bind_counter--;
- return 50; <- this is way too small and appears many times, I don't know what's the original value but this can't be correct
- NRF24L01_SetPower(); is not called in the transmit loop so it will stay on bind power
- convert_channel_16b_limit(THROTTLE,0,0xff); should be convert_channel_8b(THROTTLE);
- convert_channel_16b_limit(RUDDER, 0, 0x7f); should be convert_channel_8b(RUDDER)>>1; same for the other channels
- packet[5] = (packet_count++ / 3) * 0x40; might be quicker to do packet[5] = (packet_count++ / 3)<<6;
