Sorry - your information is a little vague if you want help with this!

I tried with both 1v95 and 1v94 and none worked.

Did you get the crash with 1v95?

Posting your code might help.

I tried just choosing a different pin aswell, and then i got

Ok. What pin and did yout try? What are you testing?

For the analogRead see here:

http://www.espruino.com/ESP32#gpio-pins

http://www.espruino.com/ESP32#analog-read-write-example

You should refer to the pins at the D numbers. The pins on the board may be numbered differently. Espruino uses the chip pin numbering for the esp32.

To read ADC0:
```
>analogRead(D35);
=0
```

I got the same error with both versions of Espruino.
My code is

    var dht = require("DHT11").connect(D22);
    function onInit() {
        setInterval(function () {
            dht.read(function (a) {
                console.log(JSON.stringify(a));
            });
        }, 3000);
    }
    onInit();

When a try pin D22 i get the error that i posted in the top post. Guru meditation.. When i try randomly reading pin D17 with the DHT11 module i get the answer

    {"err":true,"checksumError":false,"raw":"","temp":-1,"rh":-1}

When i do a analogRead() On pin D22 i get

E (221702) RTC_MODULE: /mnt/c/Users/rhys/esp32/edge/EspruinoBuildTools/esp32/build/esp-idf/components/driver/./rtc_module.c:554 (adc1_config_channel_atten):ADC Channel Err
E (221707) RTC_MODULE: /mnt/c/Users/rhys/esp32/edge/EspruinoBuildTools/esp32/build/esp-idf/components/driver/./rtc_module.c:581 (adc1_get_voltage):ADC Channel Err
=0.06298828125

Sadly i cannot follow the actual pin to the sensor premounted on the board.. But from a look at other projects they use pin 22.
