Remind users that the board needs to be Reset (in 'Programming mode') to be flashed – ideally a .gif animation showing someone pressing the Reset button and the light turning Red.

Upon opening makecode.chibitronics.com/beta in both Chrome and Edge, the upload button is not present on the page and cannot be clicked.

Disable the Upload button while a program upload is occurring.
Also, why do we call this "Upload" instead of "Download"? Why is this different from all our other targets? Unless there's a good reason, I'd like to stay consistent with our nomenclature.

Any code snippet with a bang doesn't compile:

let x = !true

Now that we have a home screen and in chibitronics it doesn't show up by default.
How would users get to the getting started easily?

This code does not work because pin D0 has enum value 160:

for (let index = 0; index <= 5; index++) {
    if (0 < sensing.pressed(index)) {
        rgb.setColor(Colors.Red)
    }
    loops.pause(300)
    rgb.setColor(Colors.Black)
}

You need this instead:

for (let index = 0; index <= 5; index++) {
    if (0 < sensing.pressed(DigitalPin.D0 + index)) {
        rgb.setColor(Colors.Red)
    }
    loops.pause(300)
    rgb.setColor(Colors.Black)
}

Firefox for Android doesn't show any blocks, nor will it show the simulator. It's possible to load examples, but nothing actually happens. Selecting "Play" just causes a spinning box.

The audio modulator defaults to .wav, because it is low-power and cross-platform.

However, IE11 does not support .wav, and instead must use MP3.

If you specify audioFormat='mp3' on IE11, the audio modulator will gain IE11 compatibility.

I can't drag the Is-On block into a Boolean context.

From our chat with Jie over the Makerfaire weekend, we discussed converting some of the projects in the LTC book to MakeCode. Have a first class experience for projects in the editor including tutorials and side by side content with code.

Pause block value selector should have a picker for well-known values

Try upload from iPhone and it will open a new tab.

The pin just always reads 1 and does not change after the initial click. Tested in IE11

This allows us to be more consistent with Arduino semantics.

On start will be executed by itself until it's done. Then we will register event handlers afterwards.

Pin D0 doesn't function at all, while all other pins work.

Example code:

loops.forever(() => {
    lights.digitalWritePinOn(DigitalPin.D0)
    loops.pause(100)
    lights.digitalWritePinOff(DigitalPin.D0)
    loops.pause(100)
})

The audio modulator supports a parameter, currently called modulationVersion, that defines the version of baud striping used by the playback function.

Version 2 is much better at DC-balancing the output than Version 1, which results in the board successfully programming the first time more often.

Please change modulationVersion to 2 inside editor/extension.ts

Weird items into the Lights/Set Foo To Bar block.

The RGB LED is set by a call to ledShow(). It takes a struct {g, r, b} and writes the values out the RGB LED. It supports a chain of multiple lights, and in fact we will have a SKU that is a small strip of LEDs.

Here is a function that sets the one LED. You can increase the size of "struct pixels[]" to account for more LEDs wired up, but for now lets stick with just one.

#define ARRAY_SIZE(x) (sizeof(x) / sizeof(*x))

struct pixels {
uint8_t g;
uint8_t r;
uint8_t b;
} attribute((packed));

void set_led(int r, int g, int b) {
struct pixels pixels[1];
unsigned int i;

for (i = 0; i < array_size(pixels); i++) {
    pixels[i].r = r;
    pixels[i].g = g;
    pixels[i].b = b;
}

Just like the physical board.

Only do this on the wrapper block to make it easier for beginners, but give the full flexibility of an analog Write to more advanced users.

Expectation :

When selecting a previously saved .hex file into the Import modal, or drag-drop the file into the editor, the project must be loaded.

Actual result :

The project is not loaded and a "This .hex file doesn't contain source" message appear in the web browser console.

Perhaps using a dropdown, to switch from ON to OFF on the same block.

Show both options in the Toolbox.

set PIN ON/OFF

It is not possible to stop the sound modulation. Do we want a way to cancel?

The pin selector drop-down menu is not touch friendly. Suggest to change this to a grid layout.

Doesn't display simulator or the blockly toolbox

Real Chibi-Chip hardware has seven gold debug pins, but the simulator shows eight pins.

Run this program and click on a pin. See it transition from 0->1. However, clicking the same pin doesn't transition from 1->0:

for (let index = 0; index <= 5; index++) {
    if (0 < sensing.pressed(index)) {
    	
    }
    loops.pause(100)
}
