Hi All, Iv Been Looking At Nigels Tutorials And Iv Managed To Mod His Led Matrix Code To Display A Scrolling Clock Across 2 8x8 Led Matrix Using Two 74hc595n By Spi But The Only Problem Is I Carnt Get The I2c Part To Work To The Ds1337 Rtc.
At The Moment Nothing Works But If I Comment Out The Call To Rtc_burst_rd It Scrolls Zeros Across The Matrix.
The Code Is Abit Messy As Its Alot Of Stuff Iv Found On The Net And Pasted But I Just Carnt Get The I2c Side To Work.
I Thinks Its Got Something To Do With The I2cwait After The I2c Start Call
Thanks For Any Help
Regards Jason
