This is the guide book for GR-SAKURA made by Sakura User Forum.
Blinking LED Sketch is not sufficient to new user it require many more & which is not provided for Sakura board. I face simple Timer interrupt & still no any document found at renesas web as well as from forum
We're sorry, but there is no library in Arduino, so we didn't prepare that kind of document.
Of course, it's available by RX63N, please refer below.
