    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

    @happy-hippo Music is not properly implemented in UIFlow and the walkaround for it is a bit complicated. but in essence I had to create variable for beats and DPM and then tie them all together. Unfortunately I seam to have misplaced the timing demo.

    ENV hat support UI-FLOW for M5StickC

    My env hat just arrived. Did some testing and guess what? Same problem. "Env hat maybe not connect" Env hat is working on a new stick that came with a band, does not work with another one from a previous batch. In general my observation is as follows, with band far better quality, then without it... And I cannot accept that, that's not serious enough for my purposes, name using the sticks in teaching. I can see that the additional board on that stick is soldered askew. Hilariously askew... I wonder which pin is broken, some, all? Where is the code that determines that "maybe not connect"? So yeah, there are major quality problems. When it rains with these sticks, it pours. I mean defects. Don't look for the problem in the users. We are not that dumb. Still have to check each and every one of my sticks for a bunch of problems. That's time consuming, aggravated additionally by half baked tools... So disappointing, that I keep postponing that painful task, I am not a masochist. Wanted to get impressed, but based on what I got, did not happen...

    @julienrat program translation is done in house by M5Stack. Documentation is done by a mix of in and outside.

    @yellowelise not at present but you can using micropython. @lukasmaximus89 I think made a guide for it on hackster.io.

    Unable to run UIFlow or M5Burner on Raspberry Pi 4

    @jydog Glad that you got it running. @lukasmaximus Regarding your comments about the Raspberry Pi - regarding the rate that the new model 4 Raspberry Pi's are selling, any platform like M5Stack that ignores Raspbian is taking chances of being irrelevant to a large new user base! How come you are all so Mac/Win-centric? The local Apple specialist here in my district in Berlin last year morphed into a 1 Euro shop, and now does more business! My Raspberry Pi reseller here in Berlin tells me that within less than an hour of a new shipment of Pi 4's coming in, they're all gone. When M5Stack claims to be open source, where's your source code so that folks can build for ARM systems? The M5Stack software seems to me to be 64-bit, although there's no warning on the tin about this. As I understand, the Raspi is not quite into the 64-bit system Linux club, but it's heading in that direction. Yes, I can use the Arduino IDE, but then, what's the point of using M5Stack rather than my existing ESP32 development board from NodeMCU which costs only 8.50 Euros, while a M5Stack Fire just cost me over 64 Euros here in Berlin from M5Stack's German partner Conrad? I'm sorry, but I don't see any sense in your arguments - the esp toolchain is for me confusing and overcomplicated. I can use Arduino IDE on a NodeMCU board without needing M5Stack.

    @powersoft first grab latest m5burner and flash to latest uiflow or beta. Then power off stick Hold home And power on Now stick should wake up in boot menu. Inside there is a option and inside you can change it to pure usb mode. If you will have some problems i can digg out my stick to validate this steps.

    To be honest: I like programmaning with Blockly. But on the end I have to make some changes in the code with Phyton and that makes it complicated, because I cannot directly save the changes. Examples: The network connection to Wifi in a progran written with Blockly is so slow thet I prefer to use the network library in Python. The battery level is not available in Blockly. It is in the machine lib in Python The text "\r\n" in Blockly is wrong translated to Python. In all these cases I have to make changes in the previous created code and I'm not able to save them in a convenient way.

    Hi @Gaviota glad I could be of help. The program looks great Unfortunately I don't think there is a way to post files on the forum. Other than copying and pasting the micropython output The only way is to host the file somewhere and paste the link. I would suggest the best way would be if you have a github account then make a repository with the file there and share it with us here. This would also allow for us to add it to our links of resources. Thank you for your requests, I will make sure to hand them on to the dev team. It is true that the updates on the offline version are lagging behind the online version but we will try to improve this. Blockly allows for a rectractable comment from the blocks so this shouldn't be hard to implement We used to have blocks for handling the SD card in our old platform M5GO so I don't see this as being too difficult to add either. All the best, Keep us updated on the progress of your project.

    I do have demo micropython code for that found here PaHub Code Demo It was built using UIFlows blocks but alas I didn't save the file :( BTW you have to initialise the i2c port before accessing it. I don't think the Stick C can power it which I think is the reason that it is disabled in UIFLow.

    Its common bug, neither Core nor Stick would connect to AP with space in its name. e.g. will not connect to "My Wifi" network, but will work with "MyWifi". %20 trick also didnt work for me, had to rename mine aswell
