Turnigy ESC Programming Card Reverse Engineered

[h2oreactor]

Thanks for your tip... I didn't know that there's a Saleae clone. I'll go get that soon!.

By the way, do you have tip on measuring vibrations... I'm trying to balance my motors, and I would like to know how to they compare to each other. this is for a multirotor/quad helicopter.

I'm not the best guy to ask. To measure the vibration, you can do it by feeling the vibration, or setup your flight controller to output accelerometer data to a graph and judge the results visually. If you are feeling really pro and mathy, then do analysis on the accelerometer data using statistical analysis techniques or even FFT it to find amplitudes at various frequencies

I heard you can use two small zip-ties per motor to balance motors

Quadcopters are fun, see my other video

hi, so how did you reverse engineer it, what tool did you use? hope to learn from your techniques.

@h2oreactor

All I did was connect a logic analyzer to the signal wire and analyze what happens when I power-on, and when I press the button

@frank26080115, I see, I'm thinking of buying a PC based logic analyzer too, which one do you have, and any recommendations?

Your code is very clean, neat job! Now, we can program our esc if we lost our HK programmer.

I recommend the "Seleae/ USBee / USB Blaster Combination: Mini Logic" from Itead Studio

I actually own a Saleae Logic, which is nice, but the clone I'm recommending from Itead Studio also works with USBee, which has a few more features.

The cable that comes with it suck compared to the genuine Saleae Logic, but the price difference is massive
