It includes example projects - you should work through these.

this will give you a proper introduction to the tools and how to use them - rather than just blindly jumping in at the deep end! "

Dear Andy,
Thank you for the impetus.
Just now I successfully compiled the following lcd8helo.c with µVision2.Only problem I faced was that I had to open the .lst file generated,go to the end of it to see.
"C51 COMPILATION COMPLETE. 0 WARNING(S), 0 ERROR(S)".
I wonder why can't I see it in the IDE.

Dear Andy will you now help me in alarm.c?This was a chance to learn C51 while working.I just did a double alarm software clock without RTC.I can always go back to my established assembly codes for 4bit lcd and appl note 95 for writing in DS1307 ram?.In fact a system loaded with ds1307,at24c16,max232 and AT89X52 is lying ready on my table.You can appreciate that only for multiple time checking I thought of using C,(just to avoid typing multiple cjnes),be that SDCC or µVision2.
Regards
Rudra
