@robski Make sure the USB-C port has enough power to meet the Tab 5's power requirements. Try different USB ports, as some may be underpowered. Also, consider if too many devices are hogging power or if the port is under-spec for the Tab5.

As far as I know, UIFlow2 does not automatically upload Python files in “Project Files” when importing a custom block from .m5b2. Manual uploading is still required to get blocks working on the device. To reduce this step for students, consider writing a block or script that automatically uploads the necessary Python files.

I think this is the solution.
pinMode(DATA_PIN, OUTPUT) is the KEY which set the GPIO pin of LED mode to output.

auto cfg = M5.config(); M5.begin(cfg); pinMode(DATA_PIN, OUTPUT); // <- Add this FastLED.addLeds<NEOPIXEL,DATA_PIN>(leds, NUM_LEDS); FastLED.setBrightness(50);

Hello.

Has this been fixed? It still overwrites the whole UiFlow2 app and I have to use the M5Burner to bring it back. Making the .py file manually and uploading it to the app folder is a pain.
I am using a M5Go / Core1.

Nice! That looks great :)

Thank you so much for posting this. This works perfectly for my M5 Paper as well (changing out the hardware numbers as needed). I was able to write some custom blocks based on this. <3

@davievans That setup sounds reasonable. Just make sure the LED driver you choose can handle the current spike your IR diode needs, otherwise the range won’t improve much. Have you already checked which GPIO pin on the Stick you want to use for triggering the module?

Dear Simone,

I also stumbled upon this issue. I finally figured out that the m5stack Unit Flashlight module has two operation modes.

It defaults to FLASH which is controlled by some custom logic which can be found here:
https://github.com/m5stack/M5Unit-FlashLight/blob/main/SetFlashTimeAndBrightness/SetFlashTimeAndBrightness.ino

But you can open the device and switch it to TORCH mode using a physical switch inside. Then you can use PWM to control it.

The details regarding the operation modes and PWM can be found in the specs starting at page 12:
https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/unit/FlashLight/FLASHLEDDRIVER_2019-07-01.PDF

This will hopefully help others stumbling upon this.

Best regards
