TinyRF85 example does not compile

[themelispan]

I tried compiling the TinyRF85 Receiver example with board "Digispark (Default - 16.5MHz)" which is my digispark ATtiny85 board. I chaged the line #include <SoftwareSerial.h> to #include <SoftSerial.h> because the compiler thought it should use the ESP8266/ESP32 SoftwareSerial library. Still, I am getting the error 'SoftwareSerial' does not name a type.

C:\Users\theme_9p6cezr\OneDrive\Arduino\Tiny85_RC_car_receiver\Tiny85_RC_car_receiver.ino:13:1: error: 'SoftwareSerial' does not name a type SoftwareSerial mySerial(3, 4); //rx, tx ^ C:\Users\theme_9p6cezr\OneDrive\Arduino\Tiny85_RC_car_receiver\Tiny85_RC_car_receiver.ino: In function 'void setup()': C:\Users\theme_9p6cezr\OneDrive\Arduino\Tiny85_RC_car_receiver\Tiny85_RC_car_receiver.ino:31:3: error: 'mySerial' was not declared in this scope mySerial.begin(115200); ^ C:\Users\theme_9p6cezr\OneDrive\Arduino\Tiny85_RC_car_receiver\Tiny85_RC_car_receiver.ino: In function 'void loop()': C:\Users\theme_9p6cezr\OneDrive\Arduino\Tiny85_RC_car_receiver\Tiny85_RC_car_receiver.ino:54:5: error: 'mySerial' was not declared in this scope mySerial.println("Buffer too small for received data!"); ^ C:\Users\theme_9p6cezr\OneDrive\Arduino\Tiny85_RC_car_receiver\Tiny85_RC_car_receiver.ino:59:5: error: 'mySerial' was not declared in this scope mySerial.println("Received corrupted data."); ^ C:\Users\theme_9p6cezr\OneDrive\Arduino\Tiny85_RC_car_receiver\Tiny85_RC_car_receiver.ino:66:5: error: 'mySerial' was not declared in this scope mySerial.print("Received: "); ^
