I have read sonme tutorials but didn't understood the whole concept ... The base document forming the reference for all questions on this is the 80C51 Family Hardware Description: http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf The ports are described in detail on pages 1-5. Please study these pages, then post back with any specific issues that you're still not clear on. You might find that it helps to re-read the tutorials in the light of those pages. It's hard to help when you just say, "didn't understood the whole concept" - people need to know where it is that you're unclear to be able to help you! Note that the 80C51 Family Hardware Description is Chapter 3 of the so-called "bible" for the 8051; the other chapters are: Chapter 1 - 80C51 Family Architecture: http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf Chapter 2 - 80C51 Family Programmer’s Guide and Instruction Set: http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf You should always have these to hand for reference! |
