Hi all, I recently started working with the FX2 chip from cypress. I connected a few LEDS to PORT B and I'd like to turn them on. I used to use the EZ-USB FX Dev. Kit and I tried adjusting the program I used to turn on the leds of the FX kit, but I get a warning Call the undefined symbol. Which header files do I need to include to get the program working? I'm using the CY7C68013 chip and the leds are connected to PB0/PB4 regards, Chris
