Quickly switching between resistive and capacitive pin touch and checking state doesn't work

[microbit-carlos]

Easier to visualise in MakeCode:

Works	Doesn't work
input.onButtonPressed(Button.A, function () { basic.showString("r") pins.touchSetMode( TouchTarget.LOGO, TouchTargetMode.Resistive) }) input.onButtonPressed(Button.B, function () { basic.showString("c") pins.touchSetMode( TouchTarget.LOGO, TouchTargetMode.Capacitive) }) basic.forever(function () { if (input.logoIsPressed()) { basic.showIcon(IconNames.Heart) } else { basic.showIcon(IconNames.Sad) } })	basic.forever(function () { pins.touchSetMode( TouchTarget.P0, TouchTargetMode.Resistive) if (input.pinIsPressed(TouchPin.P0)) { basic.showString("r") } else { basic.showIcon(IconNames.Sad) } pins.touchSetMode( TouchTarget.P0, TouchTargetMode.Capacitive) if (input.pinIsPressed(TouchPin.P0)) { basic.showString("c") } else { basic.showIcon(IconNames.Sad) } })

Replicable in CODAL v0.2.66, also adding an extra isTouched() call in case it's needed:

#include "MicroBit.h"

MicroBit uBit;

int main() {
    uBit.init();

    while (true) {
        uBit.io.P0.isTouched(TouchMode::Capacitative);
        uBit.sleep(1);
        if (uBit.io.P0.isTouched(TouchMode::Capacitative)) {
            uBit.display.print('C');
        } else {
            uBit.display.clear();
        }
        uBit.sleep(300);

        uBit.io.P0.isTouched(TouchMode::Resistive);
        uBit.sleep(1);
        if (uBit.io.P0.isTouched(TouchMode::Resistive)) {
            uBit.display.print('R');
        } else {
            uBit.display.clear();
        }
        uBit.sleep(300);
    }
}

Related to this issue, but not quite the same. That issue is about only the uBit.logo (TouchButton) not working after setting the type to resistive, this is about none of the NRF52Pin touch pins working when switching modes quickly.

• Should uBit.logo work when switched to TouchMode::Resistive? #113
