I am learning some basic ISP...

I have a display connected to an MB1 test board (http://www.displaytec.com.br/prod1.htm ). Anyone got code to read a memory address from AT89S8252 and display its value (to line 1 of display) and then modify the value (write) and display its new value (to line 2 of display). Eg

ADDR=Address VALUE=02 (original value of variable)
ADDR=Address VALUE=04 (new value of variable)

I already compiled and ran the clock example from uVision and it works. How do I change the time on the clock in real-time?

Thanks
