Hi Paul,
I encountered an issue with SoftwareSerial and PCINT. After researching I found modifying the SoftwareSerial.cpp file to avoid the port group that I was using for PCINT ought to work. I found your version on GitHub and used it for my purposes. I just commented out the def for PCINT1 and it has worked so far.
/*#if defined(PCINT1_vect)
ISR(PCINT1_vect)
{
SoftwareSerial::handle_interrupt();
}

endif

*/
Now, is it possible to move these port group defs to a "User_Setup.h" file so that SoftwareSerial will read that first to determine which ports to monitor for serial activity, giving guys like me an easier path to changing and avoiding the PCINT conflict? I would love it if these defs could be in the Arduino .ino file for ease of set up and access, is this possible?
Thanks,

John

The library doesn't support Arduino Due

error: #error This version of SoftwareSerial supports only 20, 16 and 8MHz processors

I am using the softwareserial library with RX=TX for Pin 0 on XIAO Seeed but I get no output signal. When I am spliting the RX / TX on PIN 0 and PIN 2 e.g. it works as expected.

//RX=TX
#include <SoftwareSerial.h>

SoftwareSerial mySerial(0, 0, true); // RX, TX, true =inverted

Is possible change the format 8N1 for all the others ?

Hi there, another (pedantic) automatic check revealed the following:

In case the preprocessor does not interfere, all those issues could be fixed by writing an override identifier right behind the method names.

I am using Feather M4 Express (ATSAMD51 controller on it) and I am unable to compile the code.
lib/SoftwareSerial/SoftwareSerial.cpp:362:2: error: #error This version of SoftwareSerial supports only 20, 16 and 8MHz processors

Hi,

I noticed an issue when building in debug mode with compiler optimization is switched off. This library wouldn't build anymore. Doing some research online, I found this solution which works perfectly on my branch.
In fact, to fix this just a single character change in SoftwareSerial.cpp is required in line 406 : "+r" (delay), "+a" (tmp) the +r needs to be exchanged with +w and that's it.

Here's my original thread on the platformio project: https://community.platformio.org/t/project-inspection-error-register-r24-r26-r28-or-r30-required/18648?u=schallbert

Hello there. Your library is available on platformio libraries and is signed as compatible with Nordic nRF51 platform. Apparently, it doesn't compile there

Need to add a section to the cpp file and check for: ARDUINO_TEENSY_MICROMOD

Probably like:

// Teensy MICROMOD
#elif defined(__IMXRT1062__) && defined(ARDUINO_TEENSY_MICROMOD)
  #define SS1_RX  0
  #define SS1_TX  1
  #define SS2_RX 16
  #define SS2_TX 17
  #define SS3_RX 15
  #define SS3_TX 14
  #define SS4_RX  7
  #define SS4_TX  8
  #define SS5_RX 21
  #define SS5_TX 20
  #define SS6_RX 25
  #define SS6_TX 24
  #define SS7_RX 28
  #define SS7_TX 29

I am trying to compile the example given in the library ("SoftwareSerialExample.ino") and Arduino IDE gives me an error saying:
In file included from C:\Users\myusername\Downloads\SoftwareSerial-master\examples\SoftwareSerialExample\SoftwareSerialExample.ino:28:0: SoftwareSerial.h:36:20: error: Stream.h: No such file or directory #include <Stream.h> ^ compilation terminated.

Where can I find the library Stream ?

Hello, the software serial library causes a conflict with the servo library, the servo jerks, performs micro-movements, etc. the problem is caused by the use of the same timers by both libraries and the blocking time countdown in the software serial library.

This library is not work with the arduino due i m facing some errore How to solve that errore

the errore is of util/delay.h and portmanuplation error
