hey!
Im interfacing 16F877A with PCF8583 to display time on 7Seg.
I've used Nigel Tutorial #6 (I2C Board) but i didnt find any 32KHz but 32.768KHz with 20pf capacitor.
But my clock is running really fast, its counts 1min in just 25sec.
Do i need to use 32KHz? But i didnt find it anywhere in local market.
Then i used capacitor trimmer and tunned it but time elapsed at the same rate or not at all.
Please help i need to submit this project in 3 days.
thanks in advance
