STM Timer PWM

[Lady Gaga (Gast)]

Ich habe den Timer im PWM Modus initialisiert und das Signal zappelt wie 
erwartet am PINA_0. Ich möchte aber noch gerne parallel das Signal an 
PINA_1 zappeln lassen. Geht das irgendwie? Wenn ich beide Pins 
initialisiere, sehe ich was nur an PINA0.

Ach Mist, habe die Erklärung gerade auf 
http://www.diller-technologies.de/stm32.html gefunden.

So geht das:

  TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
  TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
  TIM_OCInitStructure.TIM_OutputNState = TIM_OutputNState_Enable;
  TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_Low;
  TIM_OCInitStructure.TIM_OCNPolarity = TIM_OCNPolarity_Low;
  TIM_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Set;
  TIM_OCInitStructure.TIM_OCNIdleState = TIM_OCIdleState_Reset;
  TIM_OCInitStructure.TIM_Pulse = 160;
  TIM_OC1Init(TIM2, &TIM_OCInitStructure);

  TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM2;
  TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
  TIM_OCInitStructure.TIM_OutputNState = TIM_OutputNState_Enable;
  TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_Low;
  TIM_OCInitStructure.TIM_OCNPolarity = TIM_OCNPolarity_Low;
  TIM_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Set;
  TIM_OCInitStructure.TIM_OCNIdleState = TIM_OCIdleState_Reset;
  TIM_OCInitStructure.TIM_Pulse = 160;
  TIM_OC2Init(TIM2, &TIM_OCInitStructure);
