All technical data are important. Like :
-How to program it (protocol used for example). In general, protocols are "relatively" commons.
-Real and measured data (is it possible that someone has tested this particular controller or family controller). The china's companies are sometime in exaggeration to sell more products.
-What software to program it ? What possibilities ?
The XC chips is particular. Why ? The reason is simple : there is no datasheet and the website of the china company is not functionnal (no english translate). This is not like arduino atmel pic or stm32 !

I'm new in ebike but not in electronic... The question is more : "how to find data on this microcontrolers family". I've oscilloscopes but... don't want to do "electric" errors.

Effectively but i've mentionned the exact model to find someone who have more info than me on this serial.
amberwolf wrote:Even with identical ones from the same factory, same model number, revision, etc., may not have the same wire colors to the same places on the board (or the same connectors), depending on who they were made for and what batch they are from. (same is true of motors).
Possible but not at any time. There are similitudes on each family.
I think after many hours of research, that infos are very difficult to find for chinese controller (Buying this controller, i thought that i would have received technical data with it but NO, i'm a newbie in "ebike controllers").
amberwolf wrote:As for pictures, there is a thread at the top of every forum list called Adding Pictures with various info on that.
my usage of forums of type bb is not frequent... . This problem is now ok.
amberwolf wrote:There are also scattered other threads and posts around the forum of people asking how or it being explained, but those will take some searching.
Hours of google searching and many links but difficult to find real technical info (electronic info or connectors infos).
The goal of my post is helping me and all the people having the SAME model (or family) and why not to begin an open source controller project...but i'm new with ebike controllers.
And the last : English is not my "natural" language (i'm french)...
