Hoverboard firmware #44

Closed moezmahroug closed 4 years ago

moezmahroug commented 4 years ago

Hi, I'm a new member of this wonderful forum. I would like you to help me find a solution to my problem, please!

So, my problem is that I purchased Hoverboard for robot projects. Unfortunately, I discovered that it is not original. My project is to control their motors with Arduino. So, I tried to work on it, but I made a mistake and I lost the firmware. There are three CPUs and I only work with one of them. I will mention it in the pictures. If you can help me get him back to work as they were or given me a solution to control it with Arduino for a robot project ( forward, backward, turn left, and right, with variable speed). I would be very grateful.

type of board => YK95 V1.1

Once the firmware is erased, there is no way to recover it (as far as I know).

The board you have is not a standard board, so I don't know what will happen if you use my FOC firmware. However, I have seen people compiling the firmware on such boards, but don't take it as 100% true. I think you should check the microcontroller pinouts before flashing to avoid breaking stuff.

Hi, Thanks a lot for the quick answer. This is my mistake, I tried to open its protection, but the memory was erased. I think I will try to drive the MOSFET drivers at first if it's ok a will move on to get signals from hall sensors. I will try to find a program running on Arduino to control the MOSFET drivers. If you have any links for a program I can use it.

Something like this in the picture :
