  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!

  Hello I faced problem about digi-clock write charcter block. Problem is 3rd and 4th digit can not display with this block. I created below flow. Then Digi-Clock displays "0.1.:" for 1st and 2nd digit and colon. [image: 1778319992199-1aae8860-52c1-4c60-9097-5668ed98e2ee-image.jpeg] Howerver, index of write character block can be set only 0 to 4. Therefore it could not display 3rd and 4th digit. I think this index shoud be set 0 to 8. It doesn't work if index forced set to 5 to 8. (It was same behavior as 0 if index is set to 5.) I think the index for DigiClockUnit.set_char should be 0–8, not 0–4. https://uiflow-micropython.readthedocs.io/en/latest/unit/digi_clock.html Could you please kindly consider to fix this issue? (Or let me know please if any other solution available.) #Write raw data and write string blocks are works correctly. Using device -AtomS3 lite -Digi-clock UIFlow version:2.4.4 FW version:2.2.5 OS:Windows11 Thank you in advance Best Regards Yamada

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