Mover Simulated Wind Arduino Sketch

thanks

must come from my fan, need 170 to go up. But wasn't the case 2 days ago, I don't understand

Specs :

@GWiz I tested : https://github.com/T-622/25KHz-Arduino-Fan-PWM-Control

and it works perfectly, from 10% to 100%

would you be able and kind to make a code use for flypt ? thanks a lot

Hi dureiken, I'm very much an amateur at this kinda stuff and just bodge things together whilst trying to work it out from reading on the internet. My attempts at coding have the elegance of a hippopotamus doing ballet. I've no idea if this will work, but I've inserted the basic premise from the Wind sketch into the PWM timer control sketch you linked. Try connecting the PWM of the fan to pin 9 and use the slider on the Left Wind channel from the Mover file I attached. You may need to add a REMAP filter if it only responds over certain values.

But like I say, it may not work at all, in which case greater minds will hopefully shed some light.

Code:

const byte OC1A_PIN = 9;
const byte OC1B_PIN = 10;

const word PWM_FREQ_HZ = 20000; //Adjust this value to adjust the frequency
const word TCNT1_TOP = 16000000/(2*PWM_FREQ_HZ);

byte bytesBuffer[4] = {0};

void setup() {
 
  // Start serial communication
  Serial.begin(115200, SERIAL_8N1);
 
  pinMode(OC1A_PIN, OUTPUT);

  // Clear Timer1 control and count registers
  TCCR1A = 0;
  TCCR1B = 0;
  TCNT1  = 0;

  // Set Timer1 configuration
  // COM1A(1:0) = 0b10   (Output A clear rising/set falling)
  // COM1B(1:0) = 0b00   (Output B normal operation)
  // WGM(13:10) = 0b1010 (Phase correct PWM)
  // ICNC1      = 0b0    (Input capture noise canceler disabled)
  // ICES1      = 0b0    (Input capture edge select disabled)
  // CS(12:10)  = 0b001  (Input clock select = clock/1)
 
  TCCR1A |= (1 << COM1A1) | (1 << WGM11);
  TCCR1B |= (1 << WGM13) | (1 << CS10);
  ICR1 = TCNT1_TOP;
}

void loop() {
  if (Serial.available())

  {

    // Read new byte and put it at the end of the buffer

    bytesBuffer[0]=bytesBuffer[1];
    bytesBuffer[1]=bytesBuffer[2];
    bytesBuffer[2]=bytesBuffer[3];
    bytesBuffer[3] = Serial.read();

    // Verify if we have a valid sequence

    if(bytesBuffer[0] == 0 && bytesBuffer[1] == 0)

    {

      // Set the pins values

      setPwmDuty(bytesBuffer[2]);


    }
    }


}

void setPwmDuty(byte duty) {
  OCR1A = (word) (duty*TCNT1_TOP)/100;
}

thanks a lot, works like a charm with REMAP(VALUE;0;255;0;100) !!

Hello, I used your code:

#define BRAKEVCC 0
#define CW 1
#define CCW 2
#define BRAKEGND 3
#define CS_THRESHOLD 100

int inApin[2] = {9, 8}; // INA: Clockwise input
int inBpin[2] = {7, 6}; // INB: Counter-clockwise input
int pwmpin[2] = {10, 5}; // PWM input
int cspin[2] = {11, 2}; // CS: Current sense ANALOG input
int enpin[2] = {0, 1}; // EN: Status of switches output (Analog pin)
int statpin = 13;

void setup()
{
Serial.begin(115200);
pinMode(statpin, OUTPUT);

// Initialize digital pins as outputs
for (int i=0; i<2; i++)
{
pinMode(inApin, OUTPUT);
pinMode(inBpin, OUTPUT);
pinMode(pwmpin, OUTPUT);
pinMode(pwmpin, 0);
analogWrite(pwmpin, 0);
}

// Initialize braked
for (int i=0; i<2; i++)
{
digitalWrite(inApin, LOW);
digitalWrite(inBpin, LOW);
}
}

void loop()
{
//TCCR0B = TCCR0B & B11111000 | B00000001; // set timer 0 divisor to 1 for PWM frequency of 62500.00 Hz
TCCR0B = TCCR0B & B11111000 | B00000101; // set timer 0 divisor to 8 for PWM frequency of 7812.50 Hz

if (Serial.available())
{
uint8_t Speed=Serial.read();
if(Speed>0)
{
motorGo(0, CW, Speed);
motorGo(1, CW, Speed);
}
else if(Speed==0)
{
motorOff(0);
motorOff(1);
}
}
}

void motorOff(int motor)
{
digitalWrite(inApin[motor], LOW);
digitalWrite(inBpin[motor], LOW);
analogWrite(pwmpin[motor], 0);
}

void motorGo(uint8_t motor, uint8_t direct, uint8_t Speed)
{
if (motor <= 1)
{
if (direct <=4)
{
// Set inA[motor]
if (direct <=1) digitalWrite(inApin[motor], HIGH);
else digitalWrite(inApin[motor], LOW);

// Set inB[motor]
if ((direct==0)||(direct==2)) digitalWrite(inBpin[motor], HIGH);
else digitalWrite(inBpin[motor], LOW);

analogWrite(pwmpin[motor], Speed);
}
}
}

Issue :
I have 2 fans that I would like to control individually, with this code only 1 fan works and I am clearly not good at finding the cause!!!

I use flypt mover, and I can run a single fan with...

If someone could explain it to me, here is my code and what I have under flyPT mover (the rempa works very well for the fan which turns...)...

I also attach the arduino sketch of my assembly to understand....

Another code that works when I send the data to the arduino monitor: 000 255, motor 2 is running, 255 000, the right motor is running and if I put 255 255 both are working.

Problem I put <L> and <R> with an output which gives me 000 000 under flyPT mover nothing seems to come out, as if arduino did not understand the sending of FlyPT ???? ?
Help ! I don't see what is wrong, the code works very well under arduino with the monitor, why does it not work with FlyPT???

// Define pins for L298
#define ENA 10
#define IN1 8
#define IN2 9
#define ENB 5
#define IN3 7
#define IN4 6

void setup() {
// Initialize serial communication at 9600 bits per second:
Serial.begin(115200);


TCCR2B = TCCR2B & B11111000 | B00000101;

// Set all the motor control pins to outputs
pinMode(ENA, OUTPUT);
pinMode(IN1, OUTPUT);
pinMode(IN2, OUTPUT);
pinMode(ENB, OUTPUT);
pinMode(IN3, OUTPUT);
pinMode(IN4, OUTPUT);

// Initially stop both fans
// stopFans();
}

void loop() {
// Check if data is available to read
if (Serial.available() > 0) {
// Read the incoming string:
String command = Serial.readStringUntil('\n');

// Parse the command
parseCommand(command);
}
}

// Function to parse and execute the command
void parseCommand(String command) {
// Example command format: "000 000"
if (command.length() == 7) { // Ensure the command is the correct length
int f1Value = command.substring(0, 3).toInt();
int f2Value = command.substring(4, 7).toInt();

// Constrain values to 0-255 range
// f1Value = constrain(f1Value, 0, 255);
// f2Value = constrain(f2Value, 0, 255);

// Control fans
controlFan1(f1Value);
controlFan2(f2Value);
}
}

// Function to control fan 1
void controlFan1(int speed) {
if (speed > 0) {
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);
analogWrite(ENA, speed);
} else {
analogWrite(ENA, 0);
}
}

// Function to control fan 2
void controlFan2(int speed) {
if (speed > 0) {
digitalWrite(IN3, HIGH);
digitalWrite(IN4, LOW);
analogWrite(ENB, speed);
} else {
analogWrite(ENB, 0);
}
}

// Function to stop both fans
// void stopFans() {
// analogWrite(ENA, 0);
// analogWrite(ENB, 0);
// }

The solution is here, I opened a post with a question and I indicated the solution:
