I’m also exploring how these concepts relate to retro hardware and emulation setups—for example, learning how old consoles handled input/output signals. For anyone interested in that side of electronics, I keep some BIOS documentation here: www.ps2biosonline.com
It is useful if you’re studying how classic systems manage boot processes while working on Crowbits-based learning projects. Would love to hear what other Crowbits projects people are building

]]> Color sorter and letscode bugs https://forum.elecrow.com/index.php?p=/discussion/163/color-sorter-and-letscode-bugs Sat, 31 Jul 2021 16:12:29 +0000 Crowbits martasoft 163@/index.php?p=/discussions Got my inventor kit and I built the color sorter. Some instructions are too small, had a hard time figuring out how to build it but I managed to do it. I tried loaded the corresponding program but flashing it alway gave me the following error:

Welcome to Letscode

Traceback (most recent call last):
File "main.py", line 82, in e>
File "main.py", line 38, in init
OSError: [Errno 19] ENODEV
MicroPython v1.15-64-g1e2f0d280 on 2021-06-30; micro:bit v2.0.0 with nRF52833

So I rewrote the whole thing and once flashed when connected to my color sorter, everything turned on, it started working.

Did a bit of tweaking, tried to flash it again and I'm getting the above error again. Tried a new hello world program and it keeps giving the same error. How can I solve it?

  • Also in mac version: save project does not work, not from file menu and not from file/new
  • File browser (mac) has main folders in chinese

When it was working I did some tests with the colors sensor placing different colored pebbles in front of the sensor and getting R, G and B printed out. It was always some form of brown, it did change rgb brown from one pebble to the next, tried also with colored paper. Always some brown. I there a best distance from the object?
