• Connecting ARM controller to TTL logic levels
    I have an LPC2119 controller. The GPIO pins operate on 0-3.3V levels. I wish to interface this to an LCD controller which operates on 0 to 5V (the minimum input value recognised as high is 3.5V), therefore...

  • Chat Long Distance With STM32S, Use the UART port to connect to a walky talky
    Please tell me if that is a great idea or a really great idea. Anyway, the theory is that you can connect 2 STM32S to walky-talkies, and then transmit data readable only by a touchscreen, over a...
