https://community.nxp.com/t5/LPC-Microcontrollers/LPC1549-blink-darn-you-blink/m-p/2067548#M57968 <P>I have the LPC1549 on its own board and I am trying to get familiar with MCUExpresso by using the periph_blinky example. It builds and flashes successfully. Since it is not on the development board, I need to reassign the LED pins. It is clear in the systick.c file where the LED pins are set:</P><DIV><DIV><P><SPAN>Board_LED_Set(0, false);</SPAN></P><P><SPAN>Board_LED_Set(1, </SPAN><SPAN>true</SPAN><SPAN>);</SPAN></P></DIV></DIV><P>&nbsp;</P><P>However, I can't find where the pins are defined. Where do I find where pins "0" and "1" are defined? I need to change them to PIO0_22 and PIO0_23.</P><P>Thanks!</P> Mon, 24 Mar 2025 21:28:10 GMT DanielLongo 2025-03-24T21:28:10Z https://community.nxp.com/t5/LPC-Microcontrollers/LPC1549-blink-darn-you-blink/m-p/2067548#M57968 <P>I have the LPC1549 on its own board and I am trying to get familiar with MCUExpresso by using the periph_blinky example.
