I am doing project in which i will be having two dc sources.
One is Consistent 12v and onther one is fluctuating...
I will be using analoge comparator of AT89C2051,
I am having two problems
1)during using keil 5.0 i use <reg89x51.h> and <at89c2051.h> but after debugging and run messege appears "cant open the file"
2)I want to turn on severel optocouplers PC817 using PORT 1 pins....
Can port 1 pins provide enough voltage and current to drive pc817?
