This was caused by a missing double quotation mark in a file name in an "Execute code" block.....

You want UNbuckled "Grove" connectors to fit all M5Stack devices. For example, the M5StickC-Plus will accept both unbuckled and bucked connectors, but the Core2 will only accept an unbuckled connector. If you have the buckled type, you can always cut the clip off so it will fit.

Generically, these connectors are called "HY2.0-4P" although nearly all vendors sell them as "Grove".

There's no standard for the Vcc and logic levels! So make sure your devices match. M5Stack devices supply 5V on the red conductor, but the logic levels are 3.3V.

Using //https://101010.fun/iot/m5stickc-plus-firststep.html
for inspiration, we can upload this program:

#include <M5StickCPlus.h>

void setup() {
M5.begin();
M5.Lcd.setTextSize(3);
M5.Lcd.setRotation(3);
M5.Lcd.setTextColor(TFT_ORANGE);
}

void loop() {
M5.update();
soundTest();
}

void soundTest() {
for (int tone=100; tone < 4000; tone=tone+50) {
M5.Lcd.fillScreen(BLACK);
M5.Lcd.setCursor(80, 50);
M5.Lcd.printf("%d", tone);
M5.Beep.tone(tone);
M5.Beep.update();
delay(200);
}
}

According to my ears there is a definite peak about 2500 Hz, with frequencies under 250 Hz and over 3000 not audible. Your ears may vary .....

I am trying to get the program to ignore failure to connect to WiFi. I tried to place a Wifi Connect block inside a try/except (with a bogus SSID/password):

Instead, the program hangs, before the LED comes on, because the python that gets generated places the wifiCfg.doConnect up at the top of the program (line 20):

and the try/except block is empty, much later in the program at line 87:

Is there a way to create an exception for WiFi failure to connect?

I also notice that UIFlow does not have a "pass" block. I just put a wait() in mine - ???

Isn't the method called pushSprite?

On a M5StickC-Plus, I use:

setup():
TFT_eSprite sgraph = TFT_eSprite(&M5.Lcd);
...
sgraph.createSprite(GRAPHW, GRAPHH);
...

loop():
...
sgraph.pushSprite(TEXTW, 0);
....

I got the bar graph demo to work:

• Using the latest M5 board package, you should see a board "M5PaperS3", so the requirement to downgrade the esp32 board package to 3.0.6 is not necessary. Use the "M5PaperS3" board definition instead of the generic ESP32S3 one.

• The instructions to install epdiy are somewhat vague. Simply clone the epdiy library to your arduino library directory and it will work, doing a "make" is not necessary.

• Follow the rest of the instructions at https://docs.m5stack.com/en/arduino/m5papers3/program, pay careful attention to the special board settings for OPI PSRAM, etc.

@wsanders SOLUTION: Use "Original Network Function" blocks instead.

I'm trying to get decent-looking fonts on the PaperS3. As called by setFont, the fonts are huge and blocky (unaliased). However, If they are subsequently scaled by setTextSize, even wth a scale of 1.0, they are the right size and smooth.

You have to experiment. For example, with Font6 and Font8, punctuation charactersaren't rendered, I am guessing to save space. But Font4 scaled up to 2.0 looks very nice.

I've attached a couple of images that show this effect:

M5.Display.setFont(&fonts::Font4), without scaling:

M5.Display.setFont(&fonts::Font4);
M5.Display.setTextSize(2.0);

Not sure if this is a bug or a feature, but it works!
