software reset

Is there a "software restar command" for the Moddable Two? (like reset button)

There is a restart function available as part of some examples. There is not, however, a standalone restart function. We should do that, and the Host Provider Instance in our work with Ecma TC53 is probably a good place for it.

Meanwhile, it is easy to add yourself. The details are explained step-by-step in our book, IoT Development for ESP32 and ESP8266 with JavaScript, in the "Adding Native Code" chapter. Restart is very much like the random integer example on pages 521-523..

I'll just give a quick summary here. You need to add one file to your project folder. Name it restart.c. It just contains a native function to invoke the restart function in the ESP-IDF:

#include "xs.h"

void xs_restart(xsMachine *the)
{
	esp_restart();
}

Then in your project, declare a JavaScript function to connect to the native function (the @ syntax defines the connection). From there, you call it like any other JavaScript function.

function restart() @ "xs_restart"

restart();

To build restart.c, you need to add the file to your manifest. Here's how that looks if you add it to $MODDABLE/examples/helloworld/manifest.json:

{
	"include": "$(MODDABLE)/examples/manifest_base.json",
	"modules": {
		"*": [
			"./main",
			"./restart"
		]
	}
}

Good luck!
