is showAnimation a supported API?

see this example...

Why is serial only present in an isolated example of on radio received?

Serial is present on data received in this example

basic.forever(() => {
    radio.sendNumber(input.acceleration(Dimension.X))

radio.onDataReceived(() => {
    led.plotBarGraph(radio.receiveNumber(), 1023)
})

Serial is not present on data received in this example. Why is this the case?

let jumps = 0
basic.forever(() => {
    let acc = input.acceleration(Dimension.Y)
    if (acc > 2000) {
        jumps = jumps + 1;

Run / Compile does not work

1 open Edge

2 codemicrobit.com/lessons

3 (example) https://codemicrobit.com/lessons/charting/activity

4 i would expect the program this program to run in the simulator

1. go to many part of the documentation

2 usage of showAnimation

http://localhost:3232/lessons/smiley/activity

1. this should be changed to supported API, ie. showLeds

when errors in code, students don't know an error exists.

• run should work
• compile should work

Go to script...

1 global find <br / > tags

2 global replace with amper sign

3 allow spacing for quiz and quiz answers (fix break tags)

1 open KSF, click JS

2 type this code

let hero = game.createSprite(2, 2)
let food = game.createSprite(4, 4)
let ghost = game.createSprite(0, 0)

3 would expect for these sprites to appears on the simulator.

4 the error is shown in blocks too.. see example below

4 nothing appears when pressing run

expectation: You could receive data from a single micro:bit

1. open KSF, go to JS...

2 enter this code

basic.forever(() => {
    led.plotBarGraph(input.acceleration(Dimension.X), 1023);
});

3 it would be ideal to receive Excel data from a single micro:bit using acceleration, it doesn not appear possible.

open js, enter code

 let ghost = 0;
 let food = 0;
 let hero = 0;
hero = game.createSprite(2, 2);
food = game.createSprite(4, 4);
ghost = game.createSprite(0, 0);

an issue occurs on latest

is this intentional ?

1 open JS

1. type code - error free

let hero = game.createSprite(2, 2);
let food = game.createSprite(4, 4);
let ghost = game.createSprite(0, 0);
ghost.change(LedSpriteProperty.Blink, 100);

1. type code - error free

let hero = game.createSprite(2, 2)
let food = game.createSprite(4, 4)
let ghost = game.createSprite(0, 0)
ghost.change(LedSpriteProperty.Blink, 100)

convert input light level to JS - automatic set var to 0

1 why do you need to store light level as 0?

2 enter this code in blocks

let light = input.lightLevel();

3 then press show in code

4
this is the code that appears

 let light = 0;
light = input.lightLevel();

2 i would expect when converting from blocks to JS, the code would appear like this

let light = input.lightLevel();

music blocks - blocks to JS

1 in reference to the light beatbox lesson

http://localhost:3232/lessons/light-beatbox/activity

2 enter this code with blocks

let light = 0;
input.onButtonPressed(Button.A, () => {
    music.rest(music.beat(BeatFraction.Sixteenth));
    light = input.lightLevel();
    if (light < 25) {
        music.ringTone(music.noteFrequency(Note.C));
    }
    else {
        music.ringTone(music.noteFrequency(Note.A));
    }
});

3 press convert.

4 i would expect the code to be equal to the following when using ringTone using JS without Blocks

input.onButtonPressed(Button.A, () => {
    music.rest(BeatFraction.Sixteenth)
    let light = input.lightLevel()
    if (light < 25) {
        music.ringTone(Note.C)
    }
    else {
        music.ringTone(Note.C);
    }
})

4 however, the conversion is not 1:1. Am i missing something when using music with JS vs using music with blocks ?

importing not working

basic.forever(() => {
    basic.showString("Hello!")
})

We should reconsider -- or -- deprecate the difference of semantics between blocks and js.

the code is working in microbit.co.uk, not in codemicrobit.com

repro:

import code to microbit.co.uk

https://www.microbit.co.uk/jvkblk

import code to codemicrobit.com

https://codemicrobit.com/tgukzgtdzg

 let higherLimit = null;
 let voltage = null;
 let high_voltage = null;
input.onButtonPressed(Button.A, () => {
    basic.showNumber(high_voltage);
    basic.pause(2000);
});
high_voltage = 0;
higherLimit = 1024;
basic.forever(() => {
    voltage = pins.analogReadPin(AnalogPin.P0);
    if (voltage > high_voltage) {
        high_voltage = voltage;
    }
    else {
        led.plotBarGraph(voltage, higherLimit);
    }
});

here is a screenshot of the program working

when this program is loaded in codemicrobit.com, the same program is NOT working

 let voltage = null;
 let higherLimit = null;
 let high_voltage = null;
input.onButtonPressed(Button.A, () => {
    basic.showNumber(high_voltage);
    basic.pause(2000);
});
high_voltage = 0;
higherLimit = 1024;
basic.forever(() => {
    voltage = pins.analogReadPin(AnalogPin.P0);
    if (voltage > high_voltage) {
        high_voltage = voltage;
    }
    else {
        led.plotBarGraph(voltage, higherLimit);
    }
});

screenshot

the error message is ...

Voltage implicitly has an error type...

So I changed this to...

 let voltage = null;
 let higherLimit = null;
 let high_voltage = null;
input.onButtonPressed(Button.A, () => {
    basic.showNumber(high_voltage);
    basic.pause(2000);
});
high_voltage = 0;
higherLimit = 1024;
voltage = 0;
basic.forever(() => {
    voltage = pins.analogReadPin(AnalogPin.P0);
    if (voltage > high_voltage) {
        high_voltage = voltage;
    }
    else {
        led.plotBarGraph(voltage, higherLimit);
    }
});

possible issue:

the variables are not updating -> variables consistently showing Null
