Conversations at the field really show how little I know ... First off, I get that a Tx / Rx pair feeds the servo signals telling the servo where to position the arm between 0 and 180 degrees based on the length of a pulse (from 1 ms for 0 to 2 ms for 180). And that the pulses are transferred to the servo in a frame every 20 ms or a frame rate of 50 frames per second. So the Tx / Rx pair can tell the servo to position the arm at a specific location 50 times a second. Cool. (I understand that 20 ms is sometimes 22 ms, or 14 ms or 11 ms or 7 ms depending on the Tx in question - just using 20 ms as an example) How small of an increment can be sent? I can see a servo that is either open or closed having to deal with just 2 signals - pulse of 1 ms and pulse of 2 ms. So either the arm is positiioned at 0 degrees and stays there or it is positioned at 180 degrees when it gets the 2 ms pulse. If the increment allows the arm to be positioned at each degree from 0 to 180 then there would be 181 different length of pulses to tell it the different positions. If you wanted 1/2 a degree positioning between 0 and 180 - then what - 361 different length of pulses? So what does transmitter resolution mean? I have a DX7 (not SE) which has a resolution of 1024. The DX7SE has a resolution of 2048. The SE has a finer resolution. OK fine. What does "resolution" have to do with the ability of a Tx / Rx pair sending "arm positioning pulses" to the servo? I hope this makes sense to somebody and that that somebody can shed some light on this thing called resolution. Thanks for sharing ...
