CAPCOM6 PWM erzeugen???

Hallo, jemand da der sich mit dem Infineon XC167 und dessen CAPCOM6 auskennt? Ich möchte ein PWM Signal erzeugen. In den Regs siehts gut aus aber an den Pins kommt noch nichts an.

Hi Martin,

you must configure the output pins of the port (alternate functions).

E.g.

///  -----------------------------------------------------------------------
  ///  Configuration of the used CCU6 Channel Port Pins:
  ///  -----------------------------------------------------------------------
  ///  - P1L.0 is used for CAPCOM6 output (CC60)
  ///  - P1L.1 is used for CAPCOM6 output (COUT60)

  ALTSEL0P1L    |=  0x0003;      // select alternate output function
  P1L   = (P1L   & ~(uword)0x0003) | 0x0003;    //set data register
  DP1L  = (DP1L  & ~(uword)0x0003) | 0x0003;    //set direction register

That should be all.
