Right, removed the external library (using the CLI) and the.piolibdeps folder and ran pio run -t clean. I now have No such gpio.h on SoftwareSerial.cpp:27:18, on either 5.0.4 or 3.4.1. At high bitrates (115200bps) send bit timing can be improved at the expense of blocking concurrent full duplex receives, with the SoftwareSerial::enableIntTx(false) function call. The same functionality is given as the corresponding AVR library but several instances can be active at the same time. Speed up to 115200 baud is supported. Implementation of the Arduino software serial for ESP8266/ESP32. SoftwareSerial Library Download: SoftwareSerial is included with Arduino Real UART Serial The hardware UART Serial port should always be used, if possible, before considering SoftwareSerial. On Teensy, the hardware UART serial port completely separate from the USB port. On Arduino boards, the main hardware serial port is used for programming and sending messages to the Arduino Serial Monitor.

ReferenceLanguage Libraries Comparison Changes

SoftwareSerial Library

The Arduino hardware has built-in support for serial communication on pins 0 and 1 (which also goes to the computer via the USB connection). The native serial support happens via a piece of hardware (built into the chip) called a UART. This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer.

The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name 'SoftwareSerial'). https://wbszab.over-blog.com/2020/10/good-screenshot-app-for-mac.html. /epson-l220-wic-reset-key-generator.html.

Limitations

Because it's not supported by hardware, the library has a few limitations:

New Softwareserial Library Download

• Only speeds up to 9600 baud work
• Serial.available() doesn't work
• Serial.read() will wait until data arrives
• Only data received while Serial.read() is being called will be received. Data received at other times will be lost, since the chip is not 'listening'.

SoftwareSerial appears to have some timing issues and/or software issues. Check this forum thread for discussion.Software Serial Discussion. In particular, if you are having problems using SoftwareSerial with an Atmega168 chip delete SoftwareSerial.o in your Arduino directory.
