Hello,
I read the relevant topics in the forum, but I couldn't get the result I wanted.
I have an e-bike BLDC controller(I guess it has XCM microcontroller), made in China, without documentation. I don't know if it would be OK to share a link, you know, it is with metallic gray boxes one. I can view speed data with the LCD screen. How can I find out which communication protocol is used during this data transmission? I can understand that mostly UART is used. I hope to understand the incoming data with a MCU. I plan to reverse engineering using CH340 and digital oscilloscope but I would be very happy if anyone with previous experience could help. So, yes, I know what I what to do, but I haven't seen any users achieving any successful results.
Thank you for your tolerance and answers.
