Hi, I have just tried creating new LPC1346 project with CMSISv2p10_LPC13Uxx and DSPLIB_CM3 libraries included. I don't understand why I get error from the first line I included in the main program "LPC_GPIO1->DIR |= (1 << 25);" 'LPC_GPIO1' undeclared (first use in this function). This line perfectly worked in my LPC1114f project....

Could some one tell me what I am doing wrong and how the line should look like? Thank You

Hello my friend.

Try this:

LPC_GPIO->DIR[1]  |= (1 << 25);

Found my answer by surfing cmsis library it had to be LPC_GPIO->DIR[1].....
