he Tri-color LED on the FRDM board contains three LEDs with colors red, green and blue. Each LED connects to it's own pin on the KL25Z. The pin numbers are Red - Pin 53 Green - Pin 54 Blue - Pin 74 Find the pins on the KL25Z device on page 3 of the FRDM schematic diagram Download FRDM schematic diagram. They are on the right side of the big symbol which is the KL25Z. All the internal connections possible for each pin are summarized in the pin name on the KL25Z schematic symbol. What are the possible Port connections for each of the red, green and blue LEDs? These are the "PTxy" part of the name. The "x" in the name is the PORT (A, B, C, D or E). The "y" in the name is the PORT and GPIO pin number (0 to 31). For example, something connected to Pin 73 can connect to PTD0. Which is PORT/GPIO"D", pin "0". Here is a snippet of the schematic if you don't want to go to the full document. Write down the Port connections for each LED color. if you need to open image in a new tab then zoom in
