LCD problem with 16F628

[HenrikOlsson]

Your code says RS is PortB.4 while you say it's PortB.5.
Your code says E us PortB.5 while you say it's PortB.6.

Thanks, fixed that, but still does not works...

[mehmetOzdemir]

can you share your config settings?

not suprised , it's certainly an odd use of the lcdout 254 directive

[HenrikOlsson]

Nice one Richard, don't know how I missed that!

[CuriousOne]

Haha thanks!
Fixed it. But there were other issues too, MCU itself was also defective, replaced it, and everything works now just fine.
