Hello Dudes.a few month ago i bought one HY-LPC1788-CoreBoard (Gold Color!) And I started to using it in my project.Fortunately,I Could run the LCD,Touch & USART and THE RED LED on the LPC1788.But If i change the PORT and PIN it don't work. for example when i choose the on board led (P2.21) its working good and after that when i change the port (for example change P2.21 to P3.21 OR P2.21 to P0.21) it is not working. What is wrong with this LPC1788-CoreBoard !?? and this is my code.... 0up.ir/do.php Tanx.
