Yichip programming

[Gaucho78]

Let’s see Who Is on this forum.
I purchased a low cost diagnostic tool for cars (elm327 clone) and i’m tring to make a reverse engineering.
It uses a yichip where the top marking is partially deleted but i was able to read it. it Is a YICHIP YC1155. Can you help me to find the way to repeogram it? Which Is the method, the programmer to use and the required IDE?

The chip:

Well the best programmer i know is a Willem Programmer check it out worth a look

​

 

[Gaucho78]

That programmer It’s not related to Yichip, neither on arm cortex M0 with this size, if I Well understood

Can I ask why you want to reverse engineer the bluetooth chip ?

That isn't the part that does the diagnostics, only the connection between your "device" (phone, laptop etc) and the car.

Scope: Create a loop to periodically check motor rpm, and with a gpio control a led strip 2812A according to motor speed

On the board there is also a chip labelled fkcym438. i’m not sure but i suspect it Is a elm327 clone. During weekend i will reverse Engineer the wiring diagrams in order to confirm my theory

My brain hurts.

My brain hurts.

I can reverse engineer that for you

I’ve found the programmer:

Nice one quite cheap aswell

I found the sdk. Who Is interested may contact me in private

 

[spud1966]

Sdk ?

 

[Rumpelstiltskin.]

Sdk ?

Software Development Kit?

You posted asking a question to help you with your goal and you "expect" to get likes ?

I registered to try to write you a PM, but can't find the button xD
could you please send me the SDK? I have the same chip and want to decrypt a BLE remote control that speaks with it - hopefully the encryption is standard enough to be in the SDK.
