An NRF24L01 FHSS homebrew "10 Channel Reeds" emulation
Posted: 05 Dec 2024, 15:50
I've completed a 10 channel Reeds emulation using the 'lockdown' homebrew FHSS code, as you'd expect its a true and accurate reeds emulation with variable servo transit speed, reeds progressive elevator trim plus trim on all channels, ATV adjustable travel volume per channel, range-check sweep, Single-Channel compound and sequential escapement emulation, inactivity alarm, audible mode identifiers etc. It borrows code from my Reeduino project but instead of driving an expensive conventional PPM RF module, it uses a very cheap NRF24 (typically £2-£3 each) using FHSS on 2.4g as with the other NRF projects. It works with either the original lockdown FHSS receivers or the 2024 rx update. Shaun's seen it demo'd at the club, and fancies making one himself
We've all bases covered now I think, with versions for proportional, single-channel button, 2+1, 1+1 and now reeds. The 'lockdown' FHSS project is over 4 years old now, over that period some decisions have been queried but I like it the way it is, its been 100% reliable, has astonishing range, uses a single-cell flightpack, links immediately, allows me to use any transmitter with any model (even swapping mid flight) without changing anything, has full failsafe that can be set from the Tx or Rx, yet the code is easily understood. The document is a bit rushed so may have a typo or two, I'll revisit that as & when. It should be read alongside the existing documentation here: Frequency hopping experiments on the NRF24 - & full tx/rx
I'd be dead chuffed to hear of someone else making one
Just a taster, I'll do a proper video soon:
Cheers
