Hi, everyone I've been interested in building the following for some time now:
Unfortunately it seems that I have two 3208 displays using the ht1632c chip and the project used the older 0832 display. As you might have guessed I'm new to the Arduino but was wondering how easy would it be to change to the newer 3208 display. Any help or advice would be greatly appreciated.
Can you add links to the 3208 and 0832 ?
Are these links helpful?

Thanks Krodal for your prompt replay. I came across this article:
Because I have the newer 3208 display and the Book Clock is coded for the older 0832, what alterations would be required to get this project up and running.
The code will work with the changes detailed in that post. I know because I am the author (for both BookClock and the post) 
Hi florinc,
As I said I'm new to the Arduino but I think this is where the code needs to be changed:
void ht1632_setup()
{
pinMode(HT1632_CS, OUTPUT);
digitalWrite(HT1632_CS, HIGH); // unselect (active low)
pinMode(HT1632_WRCLK, OUTPUT);
pinMode(HT1632_DATA, OUTPUT);
ht1632_sendcmd(HT1632_CMD_SYSDIS); // Disable system
#ifdef 16x24
ht1632_sendcmd(HT1632_CMD_COMS11); // 16*32, PMOS drivers
#else
// (fc)
ht1632_sendcmd(HT1632_CMD_COMS10); // 32x8, PMOS drivers
#endif
ht1632_sendcmd(HT1632_CMD_MSTMD); // Master Mode
ht1632_sendcmd(HT1632_CMD_SYSON); // System on
ht1632_sendcmd(HT1632_CMD_LEDON); // LEDs on
What would be required to change this to the newer 3208 ht1632c display.
Just add one line:
ht1632_sendcmd(HT1632_CMD_RCCLK); // HT1632C
