Re: Stock/er9x Rotary Encoder

Using a test meter measure the voltage on the connection on the Arduino. To expand on that: Get a multimeter, preferably a digital one. Harbor Freight (a bargain tool store in the US) sells them for less than $10, so hunt around a little and you should be able to find something affordable. Plug the...

Also the top right pad of the top switch. Yes, the encoder board design needs two jumpers (or a tweak to the etch resist) to be used with the Sky9X.

Re: Miniature joystick for camera

Yeah, the PSP thumb slide stick doesn't center very well. I suppose the centering spring isn't enough to overcome friction at stick center. I had to program a pretty wide dead-band on my gimbal control mixes. I wonder if the PS Vita stick is any better.

Re: er9x development

Ah, ok. How about skip the on/off setting, and use the single eeprom bit you save as part of the decimal value? Values of 0-31 would come out to 0-6.2 seconds in 0.2 second increments. You would get the greater resolution as well as extend the functional range. Perhaps even make it an exponential fu...

Or perhaps rather than mysterious integer values, you could use decimal values that correspond to standard measurable quantities, i.e. seconds per full swing.

Sounds good. As another example of possible telemetry mix uses, I had a fixed-pitch blade 120 SR heli (not that telemetry would be an option in this case - i'm using it as a functional example) that needed yaw (rudder) trim as the battery ran down. While that's probably an engineering issue with the...

Re: er9x development

That's because it isn't a two-way link. er9x spits out a PPM stream and assumes something is there to listen to it. In the case of R/C, it's a transmitter module. The module is never told which receiver/model it's trying to control - it broadcasts the PPM data along with a transmitter identifier. Th...

So does it matter if I use it with my Taranis? No, that should be fine. The mods to the FrSky module and traces on the back panel of your radio make use of two of the (otherwise unused) module socket pins to carry telemetry data. The unused pin gets isolated on your FlySky module so it doesn't shor...

Would the 2561 bin work on a 1281? If so, I've got a 1281, spare 9X and rework equipment on hand to install it. I guess I could just order a 2561, but I'd rather not throw the money at it until the additional flash (4x the m64 chip) is needed.
