[Jacob Geigle] had a problem. A GPS unit and a Bluetooth-to-serial were tying up all the hardware UARTs on an AVR Arduino project. “Software serial”, I hear you say. But what if I told you [Jacob] ...

So let’s say your using an Arduino in your project. You already have the hardware-based serial interface working with one portion of the project and need a second serial port for unrelated hardware.

前回、Raspberry Pi Zero WHを使用し、CO2センサモジュールからの測定値読み取りを試行してみた。 Windows PCでの読み取りからの流れでUSB-UART変換基板を用いてセンサモジュールを接続したが、実はRaspberri Pi Zero WHは基板上にある特定のGPIO(汎用入出力)ピンを、UART ...

This is arduino firmware to create a UDP to UART bridge device on an ESP32. It has subsequently been updated to support TCP connections as well. The ESP32 is configured as in _STA mode, i.e. must be ...

A minimal serial communication implementation using bit-banging technique, optimized for ATtiny and ATmega microcontrollers with cross-platform compatibility. This library provides transmit-only ...
