[sdiy] STM32 Nucleo + mbed

[Robert Spencer]

The end game is very simple, multiplatform SDIY biased tutorial which people can run from a browser. 

The beauty of the mbed is that a simple program to control the speed of a flashing LED with a pot looks like this…

	/* Program to set the speed of the LED, based on the position of Pot 1.
	Snug 1405 13/12/15
	*/
	#include "mbed.h"

	AnalogIn pot1 (PC_0);
	DigitalOut myled (LED1);

	int main () {
    
	  while (1) {
	    myled = 1;
	    wait(pot1/10);
	    myled = 0;
	    wait(pot1/10);
	  }
	}



There’s no need to set up the peripherals or make sure the clock is enabled. Plus it’s all browser based, so it can be run on any platform.

I know if you’ve invested a decade on your IDE, then you’ve probably got everything as you want it, but for people looking to make the transition from Arduino to ARM, this is a good way to go. Plus it’s make it easier for me to run workshops without spending ages ensuring everyone has the right toolchain setup.
