proteus 16 segment led display

if precision is not necessary you can use delay loops...or you can use clock ic like ds1307..but you can do this easily 16f628(timer1 working in32.768khz)...

sled4c display

yeah u can use internal timer module to implement delay loops
plus, if u wanna save some ports, u can use a latch such as 74hc374 to connect between all ur 7-segments and I/O pins
