    Short Clearance Teensy 4.1 mounting

    Smartled shield uses a low profile reverse entry socket mounted on the bottom of the board. The teensy is on the top of the board with the lowest profile available. The thin sockets I use are custom made in China, but I know thicker ones are available off the shelf...

    This “thread” is a place to suggest improvements to the new forum. I’ll start: There’s no email digest feature equivalent to the old forum that I found, so instead of getting a single daily email I can skim to see if someone posted something I’m interested in, I get an email for each new...

    Reliable Stream Data Delivered over Lossy Stream with TinyProtocolStream

    I'm working on a protocol that I want to run over a reliable, ordered, error-checked, and flow-controlled Stream like TCP or Websockets, as well as between two micros using a two wire UART connection. I couldn't find anything close to TCP running over UART in the Arduino space, but did find...

    SmartMatrix LIbrary, 64X32 RGB Panel, Teensey 4.1, and Raspberry Pi 3 advice

    SmartMatrix Library author here. To drive 18k pixels, you might be able to get away with one Teensy 4.1 while lowering the quality and streaming frame rate, but I'd recommend using two and dividing up your display into two parts. I'd use the Fadecandy Server port I did, which can handle 10k...

    Teensy 4.0 with OctoWS2811

    Does this mean you can drive more than 8 WS2811 strings on the Teensy 4? Looks like you can do as many strings as there are data pins when I skimmed through the code. If so, that's a pretty impressive feature I haven't seen specifically called out anywhere.
