On the note of testing I2C devices: hook them up to any VGA or HDMI port and you are good to go with a complete OS. I even have some sensors running that way on my server for domotica needs.
- tarasglek 2y agoI don't get it. How does one use vga or HDMI to hook up i2c?
- nom 2y agoYou literally just hook a device up to pin 15/16 on an HDMI port. https://mitxela.com/projects/ddc-oled https://mitxela.com/projects/ddc-oled DDC is how your OS reads the list of supported resolutions from your display and is present on VGA ports as well. It's just a low speed i2c bus and can be used for other things :)
- tarasglek 2y agoThat's so cool. I just recently saw a more recent impl of this: copying fb over spi on rpi. This approach is much more clever and equally useless
