External controlled devices

[emv]

Hello,

Could you give me an advices about connecting external devices ?
As far as I understand assigned for this purpose are:
EINT0, EINT1, EINT2, EINT4, EINT5, EINT6, CLKOUT0 and CLKOUT1.
Is it correct that I can configure each of this GPIO as output or as input pin ?
Can I use another CON4 connector GPIO's dedicated for certain interfaces as GPIO ?

With best regards,
Mikhail.

yes. You are right.

Actually you can find S3C2440 User Manual from our ftp site.

Thank you !

Do you know how are S2C2440 GPIO's reliable for static and overvoltage ?
What do you think, are optical coupler necessary ?

With best regards,
Mikhail.

It really depend. I suggest you have a check with data sheet of S3C2440. The Samsung CPU can work under industry temp. range, but I believe few engineers will select this CPU for industrial field purpose.
