mrb, aşağıdaki PID kodlarını atmel studio 6.0 da derlettiğimde şöyle bi hata veriyo;
------ Build started: Project: pid, Configuration: Debug AVR ------
Build started.
Project "pid.cproj" (default targets):
Target "PreBuildEvent" skipped, due to false condition; ('$(PreBuildEvent)'!='') was evaluated as (''!='').
Target "CoreBuild" in file "C:\Program Files (x86)\Atmel\Atmel Studio 6.0\Vs\Compiler.targets" from project "C:\Users\BERKAY\Documents\Atmel Studio\pid\pid\pid.cproj" (target "Build" depends on it):
Using "RunCompilerTask" task from assembly "C:\Program Files (x86)\Atmel\Atmel Studio 6.0\Vs\Compiler.Task.dll".
Task "RunCompilerTask"
C:\Program Files (x86)\Atmel\Atmel Studio 6.0\make\make.exe all
Done executing task "RunCompilerTask" -- FAILED.
Done building target "CoreBuild" in project "pid.cproj" -- FAILED.
Done building project "pid.cproj" -- FAILED.
Build FAILED.
========== Build: 0 succeeded or up-to-date, 1 failed, 0 skipped ==========
hatanın hangi satırda olduğunu söylemediği için bi türlü anlayamadım.
