Pico communication with Node.js over USB

Many thanks for the reply Gordon.

That does seem nice and neat. I didn't find the USB class before (https://www.espruino.com/Reference#l__gl­obal_USB).

When I try:

cat /dev/tty.usbmodem00000000001A1

I'm not getting any output - just blank. However when I connect to the board with:

espruino --board PICO_R1_3 --port /dev/tty.usbmodem00000000001A1

I see a log of correct values there. Any ideas why no output from cat?

Pico code:

var i2c = new I2C();
i2c.setup({ scl: B6, sda: B7 });
var bme = require("BME280").connect(i2c);

setInterval(() => {
  USB.println(JSON.stringify(bme.getData()­));
}, 5000)

Thanks again.
