can i connect 7 segment directly to PIC controller ??

 

can i connect 7 segment directly to PIC controller ??

In general, yes.

 

But it would be wise to put a resistor in series with the PIC output in order to limit the output current.

 

Most PICs sink/source 25ma which is enough for segments.
For common-cathode, drive the segments (1=on) through resistors. Digit select will usually require a transistor to sink all of the segment current.
You will have to write firmware to multiplex the displays for more than a few digits.
This thread and others on AAC have lots of information and code.

Good luck.

EDIT: MrChips and tshuck type faster than I do..
