Programming 8051 need help

[tsubasachrono]

Hi binu,
Right now I try to write a coding for 8051 microcontroller with ac2dc and seven segment display. Can U please give me some guidance on how to start programming ac2dc and 10pin seven segment display. Any website or example for me to refer? Thank you.

goto the 8051 asm programs in my page, you can get many examples

binu_ji,
Right now I'm trying to do coding for interfacing adc0804 with 7-segment display. The only example of coding i got is for adc0808. Any idea?

[Binu]

It is easy to get the program for ADC0804 from ADC0808. Just leave the lines which is used to select the inputs for 0808, since it can get 8 inputs.

binu_ji,
I tried looking at your code for temperature controlled fan. I don't really understand for auto and manual. Can you explain more about this to the newbies like me? Why did you use DS 1? Are you using PWM for your code? Which part of the code for PWM since I can't find it after looking at it several time.

[Binu]

DS IC's has inbuilt ADC and the output can be easily readable in standard bus.
Yes the PWM is used. It is obtained by using a zero crossing interrupt which is generated by a zero crossing circuit.
