Ich habe mal ihre code mit den IAR compiler in meines Discovery board versucht. Das scheint zu functionieren. Jeden mal das ich den user button drucke, erhoht die variable "INT_count", und die LEDS fangen an zu blinken Ich habe nur kleine aenderungen gemacht wegend andere compiler. Moglich sind andere systemfiles auch noch wichtig (Clock Init).
Ich kopîere das nochmal hierein.
Code:

Ha der Atollic compiler auchj eine debugger ?
Fiel erfolg !!
