8051 Codes and Schematics for Beginner

8051 codes

Hi,

I'm a beginner on 8051. I'm trying to use my Atmel AT89C51 microcontroller (I also have a Atmel DS89C420, if it's easier to work with) to start a simple project and teach myself about microcontroller. I also have Keil uVision2 installed as my software.

Does anyone have some simple codes or circuit schematics so that I can start learning 8051? Thx for helping.

P.S. I heard that there is something called reset circuit and oscillating circuit. I have no idea what they do, but it will be also helpful if I have those schmatics / codes.

Since Atmel DS89C420 has on-chip programmer and thus does not require external programmer, I think I might want to start with that. Most of the schematics/code I saw were for Atmel AT89C51. Any schematic/code for 89C420?

DS89C420 is created by Maxim not Atmel, search the Microcontrollers section for DS89C420 keyword and will give you a lot of threads about DS89C420 programmer schematic and layouts.
