Flashing LED


#1

Hi there.
I am a newbie and I want to start off by flashing and LED lets say from GPIO 22.
Where can I find a sample of such a simple program?
Much appreciated
Thanks

When you start-up M2MStudio, it gives you a welcome page with things like “First steps with M2MStudio” and “Discover the Open-AT Concept”.

Start by exploring them…

Hiya,

Carefully check your GPIO voltage levels and current supply ability before directly connecting a led (or anything) to a GPIO pin.

Some GPIO pins are 2.8V level, some are 1.8V - can’t remember what the current characteristics are off the top of my head.

It’s a good idea at check the Product Technical Specs before going anywhere near the I/O connector!
