Average Bid $178
Status Closed

I need a DS 1820 firmware simulator.

firmware had used the 18F252 microcontroller, and will have four keys and an LCD display 16x2 working mode 4-bit bus ( +, -, enter, tab) to program a temperature value to be simulate.

The output will simulate the one wire protocol (as slave), simulate the DS1820 response.

The LCD text will show: Temp: [url removed, login to view], where:

A: Temperature signal: (+ or -)

B: Hundred temperature digit: (0 to 1)

C: Decimal digit: (0 to 9)

D: unit digit: (0 to 9)

E: First position after the point: (0 to 9)

F: Second position after the point (0 or 5)

The Tab button will navigate between the digits, and the keys + and - will increment / decrement the value, as stipulated above.

The Enter key will update the record to the new value.
