receiving binary code from the device

switzer · Sep 15, 2021

Hi, My question concerns induction cooker: Could anyone help me please to find out how could I read the binary code which sends the signal from one microcontroller to another after klicking ON/OFF ( +/-) keypad? On the motherboard there is the microcontroller HIGHWAY..... and on the control panel HIGHWAY..... Is it possible to do it using interface UART?... or is there any other possibility? Please find below the pictures and description.

You need to reverse engineer the interface for a start, is it actually a low voltage RS232 style serial data stream (in which case you could do it with a UART), or is it something entirely different?. How many pins are used in the connection?, is it one way only, or two way?.

I would suggest a digital scope or logic analyser would be helpful - and allow you to determine the speed and type of connection. Once that's done you can connect a micro to it, to do what you wish with the data.
