Change The PWM Frequnez (~31300HZ) // Arduino Nano 33 BLE
Maybe your like
Hello, everyone. I want to drive an electric scooter and before that I used an Arduino Uno. Now an Arduino Nano 33 BLE is to be used. The problem with the whole thing is that I am showing an error when compiling de code on the Arduino Nano 33 BLE. The following is displayed: 'TCCR2B' was not declared in this scope
This is the Code:
// Pinbelegung, Nutzung der define Direktive #define routPin A0 #define yAccPin A1 #define xAccPin A2 #define PotentioPin A5 #define drehrichtungMotorLinks 6 #define drehrichtungMotorRechts 7 #define drehgeschwindigkeitMotorLinks 9 #define drehgeschwindigkeitMotorRechts 10 // Berechnungsvariablen für die Neigungswinkel (Zur Speicherung von Zwischenwerten und Endergebnissen) double gyroMesswert; double gyroNeigungswinkelNeu; double gefilterterNeigungswinkel = 0; double beschlNeigungswinkel; double beschlMesswertX; double beschlMesswertY; double radZuGradmass; double beschlUmrechnung; double gyroUmrechnung; int potentio; // Konstanten const double pi = 3.14159; // Kreiszahl Pi const double k = 0.95; // Filterkonstante const double deltaT = 0.011; // Wird für alle Zeitdifferenzen eingesetzt.

Timer 2 kontrolliert die Pins 9 und 10 pinMode(drehrichtungMotorLinks, OUTPUT); // Drehrichtung des linken Motors vorgegeben pinMode(drehrichtungMotorRechts, OUTPUT); // Drehrichtung des rechten Motors vorgegeben radZuGradmass = 180.0/pi; beschlUmrechnung = beschlSpannung/1023; gyroUmrechnung = gyroSpannung/1023; }The rest of the part consists only of angle calculations.
I just want to set a timer to increase the frequency. Since I ve noticed that it is not possible with the Arduino Nano 33 BLE , I build your help. Rewrite the part for the Arduino nano 33 ble. Only one timer is needed.
TCCR2B = TCCR2B & 0b11111000 | 0x01;
