richardk got a reaction from guidol in Rock64 LED control
Furthermore... these i2cset commands work:
i2cset -f -y 1 0x18 0x52 3 # turn off both LEDs
i2cset -f -y 1 0x18 0x52 2 # turn off white, turn on red
i2cset -f -y 1 0x18 0x52 1 # turn off red, turn on white
i2cset -f -y 1 0x18 0x52 0 # turn on both red and white
richardk got a reaction from qblueRed42 in raspberry pi 4 portotype review
So obviously it's a "joke" video. April 1st.
So, what board is it, really? The image in the video is mirrored from the real board (look at the chip labels - he printed the "Raspberry Pi 4" label backwards to compensate). I think it's an Orange Pi 2+, hacked up a bit...
richardk got a reaction from guidol in Armbian support for BeagleBone Black
Beaglebone Black (et al) are already in pretty good hands, as beagleboard.org (seems like a project of Texas Instruments employees) does well supporting their own stuff. If you want up-to-the-minute modern kernels, best by far is Robert C Nelson's work: https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone . (I support a commercial project with a Beaglebone Black inside, and I'm very pleased with the resources available.)

Just FYI, this is what I would use for UDOO Quad: http://eewiki.net/display/linuxonarm/UDOO
...but, only if you're not afraid of command line and kernel building. Robert C Nelson does good work keeping his kit current.
richardk got a reaction from StuxNet in What are you using your Orange Pi Zero for?
For my daughter: Generating sounds in a "Ghostbusters" proton pack, two of them in fact. A Python script reads /dev/ttyS2 to receive instructions from an Arduino connected to buttons/switches, and mixes/plays powerup, powerdown, idle, and fire sound effects.
