[SOLVED] line follower robot using stm 32 in keil u version with explanation

[Noor Us Sabah]

plzzzzz help me to find this code .....submissin date on this tuesday ,.....plzzz kindly

 

[embpic]

just google and get the idea and ask the question rather than full project.

Its nt found anywhere......

bt this code is not working point out mistake in it

help to pont out the mistake or changing the code....

 

[embpic]

you are getting any compilation error or code is not working on hardware.
