• Hello everyone
    sorry if I do not extend (the English is not my forte)
    not know the cause but the "HC-SR04" does not work with 1.70 or 1.71 espruino 27th Sep in stm32f3discovery. espruino 1.71 significantly improves the fault persists, tested the code and it works in ministm32_32

    Test code

    var sensor = require("HC-SR04").connect(A0,A1,functio­n(dist) {
    console.log(dist+" cm away");
    setInterval(function() {
    sensor.trigger(); // send pulse
    }, 500);
