I've tried solutions from similar problems, but none of them gave me any usable results. I'm trying to control those http://www.ebay.com/itm/311177661450 electronic speed controls (ESCs) with Raspberry Pi.
I have tried solutions from the question How to control a Traxxas XL-5 ESC directly from the GPIO?.
I've also tried couple of other solutions, but no result. Basically, when I "flip the switch", the ESC makes triple sound and then rotates motor a little bit once a second. I've tried sending a pulse with width 200 and 100 to make this so-called ESC initialization happen, but no change.
I haven't received any documentation, nor couldn't find any online, so I'm kind of not sure where is the problem coming from.
