Lcd Thermometer

I need the schematic of the circuit for “digital thermometer”, on Atmega16, with LCD 16X2… any link?

This is an on board project, that I couldn’t find the appropriate schematic which uses Atmega16, 16X2 LCD display, bias circuits and… the schematic in Protel DXP is preferred.

App note AVR063 shows the LCD and temp STK500 adapter (daughter) board and will link to the firmware.

STK500 (and other) schematics are available through the Atmel Studio4 Help files. From within Studio4 Click Help then Click AVT Tools User Guide. From the popup help screen on the left side do a search for the keyword SCHEMATIC and you will get a list to choose from.

The schematics are in PDF

I included a link to the free Studio4 development software which you will have to install if it is not already on your PC.
