====== Stm32F103PWMTest ======

===== Übersicht =====
  * Klasse CPulseWidthModulator für jeden PWM-Ausgang (und für jeden Controller-Typ) - leider bisher nicht erreicht!

===== Idee =====
  * PCA9685 16 Channel 12-bit PWM I2C-Servo-Module

===== Weiterführung =====
  * mit Dispatcher und ControllerRingBus: **Stm32CrbServoMotor**
  * ohne Dispatcher, ohne ControllerRingBus: **Stm32F103PwmTest** : 2204071805_Stm32F103PwmTest_01V08_last2xS4xM

===== Aufgaben STM32F103C8T6 =====
  * Auflösung 16bit bei PWM - konnte bisher nicht allgemein beeinflusst werden :-(
  * Wie viele Timer? ???
  * Wie viele Channel für einen Timer? ???
  * Grosse Probleme, mit Library oder auch mit PTimer->function(...) :
  * gegenseitige Beeinflussung, Interfererenzen, maximal 2 Timer gleichzeitig verwendbar

===== =====
===== 220331: Stm32F103PwmTest  =====
  * letzte Entwicklung (anstelle Stm32F103PwmMotorMinimal)
  * 2x Servos mit 50Hz (2 Pwms) TIM1
  * 2x Motoren (mit INA und INB, daher 4 Pwms) TIM2
  * letztlich automatische Pwm-Zuordnung über Bibliothek (Standard in Arduino), grausam!
  * grausam: nur Funktion setPWM(frequency, pwm) mit int-Werten - auch für pwm :-(:-(:-( -, daher nur 10 Werte im Bereich von 1 ms (left) bis 2 ms (right) [middle: 1.5 ms]

  * anderer (erfolgloser) Versuch, da nur eine Basisfrequenz für alle PWMs:
<code>
// 2kHz !!! only ONE PWM-Frequency!
void setup()
{ 
  analogWriteResolution(16);
  analogWriteFrequency(2000); // 2kHz !!! only ONE PWM-Frequency!
  analogWrite(PB11, 20000);     
  analogWrite(PB10, 40000);    
  analogWrite(PB0, 20000);     
  analogWrite(PB1, 40000);    
}
