Test of hc-sr04 fails

[Frida854]

I try 'moddable/examples/drivers/sensors/hc-sr04' but encounter this problem:
'/Users/poulborg/projects-esp32/hc-sr04/main.js (21) # Break: main: get device: undefined variable!'

https://github.com/Moddable-OpenSource/moddable/blob/2a4641e93239b371265bda4b588a7c2e718c67cf/examples/drivers/sensors/hc-sr04/single-sensor/main.js#L21(url)

How do I proceed?

Could you please share what command you're using to build? My guess would be that you're building for a target that does not support ECMA-419 I/O.

mcconfig -d -m -p esp32

Gotcha. That will not work for the reason I speculated above--that build target does not support ECMA-419 I/O, which is needed by the example you're trying to run.

The ideal fix would be for someone to add this particular development board (ESP32-PICO-KIT) as a new build target with a proper I/O provider. That requires some thought on what default pins to assign, what built-in functionality the board has, etc.

I have not done that, but I just put together a generic target that might be sufficient for you to get started: esp32_pico_kit.zip. Please try unzipping that folder into $MODDABLE/build/devices/esp32/targets/ and then building with mcconfig -d -m -p esp32/esp32_pico_kit.

Let me know how it goes!

Even after misfitting the sensor, it works now.
Thank you.

Excellent; glad to hear it.
