Hello everyone,

I recently brought below nh5100 cheap single chip development board..it has an STC 90c52rc 40dip MCU.. my problem is the manual for the development board is nowhere to be found and basically i don't know how to program it.. all i know is i have to write a suitable C program using keil software.. and upload the hex through STC isp software.. ok let me make my question lot simpler. It's a two part of course..

1) where can i find the user manual for this development board?
2) lets say that i writing a simple blink program for the mentioned MCU... how can i declare the pins... what are the name of the pins?

Thank you...
