 ===== 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
-===== Aufgaben =====
+===== Weiterführung =====
-  * Auflösung 16bit bei PWM???
+  * mit Dispatcher und ControllerRingBus: **Stm32CrbServoMotor**
-  * Wie viele Timer?
+  * ohne Dispatcher, ohne ControllerRingBus: **Stm32F103PwmTest** : 2204071805_Stm32F103PwmTest_01V08_last2xS4xM
-  * Wie viele Channel für einen Timer?
+===== 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]
