L298 driver

[Geoide]

Hello.

Is there some driver to manage the L298 motor controller?

Thanks.

It looks like the j5e/motor class of J5e may support L298. I'm not familiar enough to motors to be sure, but the implementation appears to support the PWM and direction pins that the L298 has. @dtex, can you help here?

FYI – if you aren't familiar with J5e, it is a very nice robotics library for JavaScript built on the ECMA-419 standard, the ECMAScript Embedded Systems API Specification. J5e runs on the Moddable SDK's ECMA-419 implementation.

Yes, it does support the L298, but the docs are lacking here because I want to do more testing. I can give you some sample code, but not all L298 based motor controllers are equal. Can you tell me what input pins your board has, or even better, send a link to a spec sheet?

Good afternoon!
Im trying to get the L298n motor driver to work with J5e/motor class on an ESP32 but haven't been able to yet. Theres very little documentation and a few short examples which dont really help much. Any suggestions on how to get this done? This is the last test i wrote:

import Motor from "j5e/motor";
import PWM from "pins/pwm";

export async function createMotor(){

	let motorAPinEnable = 1;
	let motorAPin1 = 23;
	let motorAPin2 = 22;

        const speedIO = new device.io.PWM({
	   pin: motorAPinEnable
	});

        const motor = await new Motor([speedIO,motorAPin1,motorAPin2]);

        motor.enable();
	motor.start();
	motor.forward(150);
}

Nothing happens haha! Thanks in advance

@dtex, any suggestions for diagnosing this?
