A Single-Channel Emulation set using FHSS on the NRF24L01

Описание: Here's a functional, usable Single-Channel Emulation system which doesnt use a conventional R/C module and R/C receiver, but instead uses full FHSS on an NRF24L01 module. The RF code is identical to the most-recent code taken from my propo FHSS project so it works to the same receivers, which can be based on the RF-Nano, or Promini with NRF24L01, etc.

Like the propo set it uses sixteen RF channels well spread through the band and has programmable failsafe on all channels. Emulation wise, it has single-channel compound emulation giving rudder, kick-up elevator and quick-blip throttle at either of two selectable compound keying speeds corresponding to 'light' and 'heavy' rattlers (similar difference to the Elmic Commander vs Elmic Conquest), also does sequential escapement emulation, has an inactivity alarm, servo reversing, Vtail & Elevon mixers, minute-minder, travel adjust (rates) with 'minimum' set for torque-rods - rudder & elevator throws are governed either by a pot on A7, or a link which gives a fixed 50% for torque-rods. It has the 'button follower' channel for driving a genuine escapement via a channel switch. The quick-blip throttle is a cyclic 4-position 'off-half-full-half' just like the PIC S/C encoder, and of course the two 'half' throttle positions dont have to be 'half' and dont even have to be the same.

Link and relink time is almost instant, the slight 'power-up' delay seen in the video is because on the development sets I still have the bootloader enabled. Finished sets will have instant startup.
