    Hi, I'm a new user of M5stack products, having got an M5StickC Plus2 recently. It's a nice device, but the documentation isn't always accurate which makes learning how to use it a slow process. I tried to use the example for drawing a raw buffer to the screen here But it resulted in different garbled output each time and not a green rectangle. It seems that the len parameter is expecting 16-bit entries in the buffer so needs to be halved. Here's the code that works on my device (note the //2 for len parameter): width, height = 40, 30 green565 = 0x07E0 raw_buf = bytearray(width * height * 2) for i in range(width * height): raw_buf[2*i] = (green565 >> 8) & 0xFF raw_buf[2*i+1] = green565 & 0xFF Display.drawRawBuf(raw_buf, 100, 100, width, height, len(raw_buf)//2, swap=False) Hopefully this will help others and eventually get changed in the docs - assuming it's the same for all UIFlow2 supported devices? If anybody knows a fix to make it work properly for lower than 16bit depth screens so I can draw a raw buffer to a 1-bit canvas properly, please let me know!

    @GiovanniCaenazzo disconnect M5Dial press and hold boot button at the back ofM5Dial - in the middle of Stamp Controller - it is very gentle switch connect M5Dial to USB M5Burner should detect com port in boot mode

    @jeanfabre On web, just choice block type. [image: 1729260517944-86b7a25c93207d9a32e5b33471bb1f0.png] For code, add return description like this: def func(self) -> int: return 0

    Looks like you got it working, but what I was referring to with the Execute block was adding the full command like this to see if it would override the first. [image: 1604065459161-screen-shot-2020-10-30-at-9.43.07-am-resized.png] In the Python tab it looks like the command duplicated. I don't have the AtomQR to test with, so I'm not sure if this works or not... [image: 1604066142567-screen-shot-2020-10-30-at-9.43.54-am-resized.png] However, I found another workaround without the Execute block. After loading the AtomicQR example flow, then switch from Atom-Lite to Atom-Matrix in the settings, it will indeed add rgb.set_screen([]) on the Python tab. This is the bug. If you just select one of the 25 LED squares in the UI editor to change it to white, then select the same square again to change it back to black. Check the Python tab again and it will now show rgb.set_screen([0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]) automatically. If you save that as a new program (ex: Atomic_QR-Matrix), the next time you load the file, it should have the Matrix as the hardware type and the correct rgb.set_screen command in the python tab.

    it is an old version program compatible problem. now we updated a new example. https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Core/Atom/Atom Matrix

    @gaviota I know this unit. But I have a unit on the MCP4728 chip. There are python libraries available but I can't make a custom block. Can you?

    @m5stack FW1.6.4 and editor 1.0.12 totally broke my program, still can't upload but then again, why would I need to, it doesn't even run anymore, the python code gets screwed up. I don't get to make an app anymore, all I do is running into stuff that doesn't work. It seems to me M5stack is suffering from what I call the "Yamaha disease" : keep spitting out new hardware without fixing the mediocre stuff they released before. Well I for one am not jumping on that train anymore , I refrain from buying any more new stuff a la core2 and whatnot before the existing stuff gets fixed. (which I expect now, will never happen)

    @ciniml could you please explain the new Cellular UIfow blocks and give an example on how to use them in sequential order? I also saw the Soracom m5f example and I wonder if the flow can start as it did, checking the SIMstate without setting any UART communication in advance? If I start running just the first two instructions, shall I expect returned True as you? I'm chasing who can help me in using the COMx.LTE module with those UIflow methods Thanks

    More specifically I need to know if the Arduino code downloadable here can be alternatively implemented by means of the UIFlow blocks belonging to the Cellular palette and, if so, I'd be interested to know how. Thanks

    @hetzer said in issue with lego+ aka DC Motor module: I cant make lego+ aka dc motor module. It gives error" moduel' object has no attribute Legoboard. Can anyone assist? I guess you are using the wrong commands in UIFlow 1.6.3. The (DC motor (Lego+) module) and its control commands UIFlow 1.6.3[image: 1600225081648-dc-modul-resized.jpg] [image: 1600225132010-dc-motor-modul-resized.jpg] The (BaseX module) and its control commands UIFlow 1.6.3 [image: 1600225213172-xbase-modul-resized.jpg] [image: 1600225273120-xbase-resized.jpg] In the description of the (DC motor (Lego+) module) the picture may be confusing because there are the commands M1 etc., but these commands are for the BaseX module and not the (DC motor (Lego+) module) !
