I need to display the temperature acquired by my LM35 on a 2 digit 7 segment display. What I have is LTD383-R2 Common Anode Display. Datasheet here.
The display has 1 Anode pin + 14 Cathode pins for he 14 segments.
Any idea on the best way to drive this (with least components)? I am using Atmega328.
The options that came to mind were
- Use a decoder. Google search came up with DS8669 from TI, but it seems that IC is now obsolete.
- Go the usual route of using a ULN2803 darlington array IC + 74HC595 shift register. But this would mean using 4 IC's in total (2 for each digit of the display)
