Hi David.
These empty slots is a digital signal value (D0 - D7).
You can use any small microprocessor that retrieves the input D0-D7 and parse the output of LCD.
It can also convert through the arrangement of the DAC analog output for analog meter.

Hi David.
The processor must be available a minimum of 14 GPIOs.
You can apply this type, which has an internal clock without the need to Xtal.
For example ATTiny2313 or ATMega8 from ATMEL.
Best regards Chris.Comment
