but , clock counts very slow !! I couldnt adjust with variable condansator !!

please help !!

thanks for your kind response
!

i started to read PFC

these codes works properly !!

i2cread sda,scl,$A2,2,[S] 'sec
i2cread sda,scl,$A2,3,[M] 'minute
i2cread sda,scl,$A2,4,[H] 'hour

but i couldn't set time ?

i connected resistors..
i couldn't read and write clock data from PFC?

ps: i read previous topics but i couldn't find solution ...

I want to use PFC8583 . But i coludn't get/set any data .

I tried

i2cread sda,scl,$A2,2,[S]
i2CWrite sda,scl,$A2,4,[H]

andi changed $A2 =%10100010 ------> %10100001..

and what...

does it work properly with my ex program which is writen for 16f877 ..!!
