Connecting to the unit.

Connection Description

For erasing and writing operations of the entire memory area, it is necessary to remove the BOOT block lock 28F400B5, for which it is necessary to solder a resistor of ~100 Ohm to the seat with the missing element.

Also, for the programmer to work, you need to connect GND on the Arduino NANO and the CEM block.

To upload a sketch, select the correct COM port and Arduino Nano board.

Run the SerialBDM.exe application, supply 12V power to the CEM unit, connect to the required COM port, and if the ROM ID is successfully read, the device is ready for operation.
