hello experts,
I'm been working mini240 for 2 months.
i have a problem while connecting i2c pcf8591 IC to mini2440.
i connected the pins as above figure but when i command it i2cdetect it
tells the address 0x48.
it is OK.
now when i do i2cset 0 0x48 0x30 0x10 and enter it doesn't show me 0x10 at
that address.
now again i read it using i2cget 0 0x48 0x30    it shows me garbage value.
what happens with this..
reply.
thank you
