#181736 - Details of components
Responding to: ???'s previous message
Hello Mr. Michael,

Yes, my mistake. I was using Atmel AT89S51.
Yes, that is all the code that I was writing into the chip.
What is the initialization code that I must insert first ?
It's been almost 8 years since my last MCU programming. I may have forgoten some details.
I was writing that code just to check if my schematics can run well. I have posted my schematics in previous thread. Here is the schematics



My latest test was just the basic circuit of the MCU, without the pull up resistor to interface with the 7 Segment Driver, without the DIP Switch and it's resistor.

Best regards,
Didik Chandra
