Hi guys
I'm beginner in ARM and have very basic question to you Im studying data-sheets and all I found on the internet but still Im confused about a lot of things.I downloaded also a few sample codes such as blinky led where is example of using GPIO as GP4DAT = 0x04000000; but cant find anywhere what does it exactly mean. Coul you please someone give me idea? You know I was use to use on AVR just PORTx = my_value and this is just something too different.
Thank you for your time...
