There is already an lcd library included in codevision, just use the lcd tab in code wizard to set the port and generate the initialization code

Have you considered a serial lcd, or making one with a small Pic or similar, there is plenty code around. Maybe you dont have a spare serial port, athough you could possibly configure any port to do this. Maybe not practical for you, but just a thought.

The main goal was to increase the frequency range but maintaining the cheapest cost. Large and inexpensive color display has been used.
Drzasiek wanted build a mobile device, so he was looking for small elements.

Why not use a PIC with built in ADC ?
Like 16F876, 16F877 they are cheap and you do not need external ADC's.
TLC549 has "only" 8 bits resolution while most PIC's have 10 :-)
You can also find many design notes how to use lcd, ADC and many other peripherals with a PIC.

Use to 2 paralel in/serial out latch register circuit (like 74LS597) for 16 keys. It consume 4 lines. The lcd can be access using 7 lines: 3 for control and 4 for data (or 6 2 control and 4 data but I do not recommend it). You can overlap the output lines for controling the serial latches with the data lines for the lcd. Until now you used 8 lines

It depends on what language you use.
- avr assembler is quite simple and well structured so you can write your program with ease. Anyway I didn't use I2C/TWI interface before, but the datasheet is comprehensive so you need to read it carefully.
- If you want to finish the project rapidly and with full features you can program it in C, using

If you ignore the lcd display part, which is for informational purposes only, you'll see, that the code is mainly reacting on the level changes of the DTMF outputs. The coding style isn't applying for a brilliancy prize, but understandable though. You need to get familiar with common methods of masking port bits and similar stuff.
