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 09A C001J0005GY and on the control panel HIGHWAY-C210F01 C034K00EPG2 Is it possible to do it using interface UART?... or is there any other possibility? Please find below the pictures and description.
Not SPI because only two signal lines available. Why do you exclude I2C?
We would use an oscilloscope to decode the communication. Attention: Control circuit is apparently grid connected and carries dangerous contact voltage. Use a safety isolation transformer or equivalent methods for isolated measurement.
