hai, everyone.
I am confuse 
how to differentiate Basic Atom and Basic Pro…
is it the same?
Got anyone expert in PIC basic Pro programming language?
Maybe this belongs in the Atom/Atom pro section? 
The Atom and Atom Pro languages are about the same.
Both the Basic Atom and Basic Atom Pro use MBasic. However, the Pro has several more commands you can use. Check basicmicro.com for the manual.
The MBasic used for the PIC is almost the same I believe.
Oh, and this thread should be in the Basic Atom forum. Not multi-leg.
haha…thankyou for answer my query …i also not notice that there is Basic Atom forum…
Then why multi-leg?
If you can’t find the appropriate forum to put stuff in, then it goes into General Discussion No worries though.
The language, i.e. the commands used to write programs, for the Basic Atom and Atom PRO are the same. However, the Atom PRO has additional commands the Basic Atom does not have. This is because the Atom PRO has hardware features the Basic Atom does not have.
Think of the Atom PRO as a superset of the Basic Atom. It does everything the Basic Atom does, plus some added things, such as having a hardware serial port, hardware based servo control (Basic Atom does it in software), etc.
