- Sat Dec 12, 2020 8:54 am #89760 I've changd in a script the hardware serial to softwareserial because a change in my hardware. I got a lot of errors so to get ride of all the errors I try to start with a fresh arduino surrounding. So I update to the arduino 1.8.12 IDE and followed this instruction (for mac):
https://arduino-esp8266.readthedocs.io/en/latest/installing.html#using-git-version

I understand the library ' softserial' is included in the esp8266 build so no need to add a softseriallibrary manually (so I thought).
Now when I/m trying to compile my code I do get an error:

Code: Select allSoftwareSerial.h: No such file or directory

This is my script:

Code: Select all/*
* This sketch reads a command through a http connection
* depending on the text received it will send open, stop or close
* commands to the Esp8266. the ESP8266 is connected to the Axa Remote 2.0 electric window opener

Do I misunderstand the fact the softserial library is included in the esp8266 build? Do I have to do something else to implant this library?

- Sun Dec 13, 2020 5:01 am #89775 SoftSerial <> Softserial !!!
just a typo ...
as when it arrives there, it allready worked before and after, the rest should be ok

- Tue Dec 15, 2020 11:03 am #89811 Why isn't this in the arduino section?
