Pypilot Motor speed Control

Hello,

I am working on the below Proof of concept for Pypilot motor Control.

Raspberry pi 4 (Having Pypilot, Open Plotter) connected with Arduino UNO that connects with Motor controller.

I have procured the BLDC Motor controller and BLDC motor from Aliexpress and the details given below. I am unclear to how customize the motor.ino file for this configuration. Also, I could not understand the correct pwm style from the given Motor Controller specification.

However, when i connected Arduino UNO (Standlone - without Pypilot) with Motor Controller, i am able to control the Motor using Analog Pot (Arduino UNO pin 9 - Motor Controller signal Pin, Arduino UNO ADC pin A0 - Analog POT) with the following sketch.

Please give some input to customize the motor.ino to control the motor per this configuration.

Arduino sketch (Standlone Arduino- without Pypilot):
===============

int motorPin = 9; // Motor connected to digital pin 9
//int val = 0; // variable to store the read value

void setup() {
pinMode(motorPin, OUTPUT); // sets the pin as output
}

void loop() {
val = analogRead(A0); // read the input pin
analogWrite(motorPin, (val/4)); // (val/4)analogRead values go from 0 to 1023, analogWrite values from 0 to 255
Serial.println(val);
Serial.println("WELCOME");
}



Motor Controller:

Re: Pypilot Motor speed Control

I have worked with arduinos and esp 's for quite some time trying to perfect an autopilot for my 38ft ketch
1. Dont waste your time with a UNO it will run out of memory and does not have sufficient pins if you start doing anything fancy

2. Dont consider the new or older ESP's -they are more powerfull etc but software/hardware is poorly suppported in comparison to arduino
3 Do buy and spend your efforts on an Arduino Mega 2560. Buy the cheaper chinese clone because the Ch 340 chip on it is more stable if you want to use older windows machines. It has 4 ports and a huge number of pins



I am updating my system to integrate a RP4 with openplotter to get over inherent arduino limitations with data - PI as HMI/wifi/ etc in display/supervisory role while leaving Mega as I/O - motors, sensors, logic software. I have had enormous issues with getting the PI working on openplotter/system K
