Hi,
how do I toggle the value of a pin by using a signal from the XMEGAs EventSystem?
I already tried the following code without success:
Code:
EVSYS.CH0MUX = EVSYS_CHMUX_PORTC_PIN0_gc;
PORTCFG.CLKEVOUT = PORTCFG_EVOUT_PC7_gc;
This only gave me 0,5us impulses on PortC Pin7 each time the value of PortC Pin0 had been modified. |

Hrmm... This post is over a year old.
It would be handy if the Event System could be used to toggle *any* pin on the XMEGA - I don't think it is possible though.
Can anyone confirm?
EDIT: This post should also be moved to the XMEGA forum. |

| Readers of this post: The Event system used as OP does it, will ONLY give a pulse lasting for ONE peripheral clk cycle, so it was working right .

Anybody DOUBT what OP's peripheral clk was running at ? 
dmginc : You can only use the pins indicated in the 'sheet, pin4 OR pin7 of the configured port . |
