Chris Efstathiou commented on Chris Anderson's blog post New product in the DIY Drones store: 8-ch PPM encoder
"About the ppm encoder and receiver compatibility:
It does not matter how the servo pulses are presented at the input as long as they are within the 800 to 2200 microseconds limit (can be changed).
They can come each one at a time, all of them at the…"

"The problem is probably that the wrong firmware is flashed or the fuses are not correctly set.
The ppm encoder can handle servo input at any order, sequential, coming in at any mixed order or all at the same time.
there are two versions the one with…"

"Since you move the stick and you have ppm output then you must have connected the aileron channel of the rx to the throttle channel (number 3) of the ppm encoder.
The PPM encoder will cut the ppm output if channel 3 has an input of more than 2025…"

"Well it was not that hard to make, the difficult part was to make it reliable enough for a UAV.
I am glad that it was found to worth something.
It would be nice if Atmel would make a simpe but faster than 20 Mhz AVR or at least make the internal…"

"One last thing i forgot to add:
Even though some receivers output a servo pulse every 14.5ms or lower, the actual servo pulse
width is updated every two servo pulses.
For example some Futaba receivers (2,4 Ghz) output all 8 channel pulses within…"

"Hi.
I am the "hendrix" who wrote the firmware (Moa wrote the pdf manual as English is not my native language)
I want to add some details to the technical aspect of the ppm encoder.
There is some jitter present in the ppm output (not much to be a…"
