LT8900 support

The RF chip on Shenqi was not written but from what I've seen from air it did follow the datasheet.
There are a lot of restrictions in the emulation like max number of bytes, method of air transfer, fec, whitening...
What I did was an attempt to get at least some parts compatible. May be Shenqi will be the only protocol using that layer...

Seems all recent toys are shifting to LT8910/LT5910 chips ....

Start to be urgent to work on this emulation ....

LT5910? What models specifically?

The LT6910 is the MCU+LT8910 combo ... even cheaper for chinese toyquadcopters. All the last toys I reviewed have it now ... last JJRC, Global drones and many more.
I feel after the XN297shift, nos it's the LT8910 ... probably even cheaper .... for mass production

Then if they start putting it in TX's as well we screwed. The price of entry rises from SPI logic analyzer to SDR.

No luckely the TX part is still LT8910 based .... so no real problem.... I can capture some data.... With a bit of luck,the datatate is one of the two in common with the nRF24L01+ (1mbits,250kbits)

Modelco mini 8 support

Hi everyone I have this nice little drone that I would like to work with my Devo 7e. The protocol you are already there?
I enclose a photo of the drone and the radio chipset.

Drone => hpics.li/52bf478

Chipset => hpics.li/c780744

I am looking forward to have this chip supported by devo. I have a RX and TX from new FY326 that are LT8910 based and Saleae analyser. Should I capture some data? Is there anyone that could use those dumps to incorporate it into devo? I mean, I'd be glad to help, but writing RF protocols is far beyond my skill set.
