Change History

• v0.1 Initial Version with Baisic Functionality
• v0.2 SPI Support & error corrections
• v0.3 I2C Support & error corrections
• v0.4 Software Serial & error corrections
• v0.5 Error corrections, cleanup and more examples
  • HardwareSerial: Corrected slow print and println
  • analogWrite correction provided by Duke Dylan
  • Moved examples documentation into examples folder
  • Examples for HC-05 and ESP01
  • This release contains the following Breaking Changes
    • Changed signature of SoftwareSerial.begin() by switching the tx and rx sequence to be consistent with HardwareSerial
    • Removed unnecessary subfolders in ArduinoCore-Pico
• v0.6 PWM, error corrections and additional examples.
  • Provide easy to use PicoPWM class which is used by Arduino analogWrite
  • Implement Servo class with examples
  • Example how to change default pins in cmake
  • provide termperature() and temperatureF() method to read the built in temperature sensor
  • This release contains the following Breaking Changes
    • Removed libarduino: all sources are complied as part of the sketch now, so that we can overwrite default defines
• v0.7 PWM reading / DMA / pico_arduino Namespace
  • Implemented Reading of PWM
  • Support for PWM in analogRead()
  • Added documentation on how to override the predefined framework #defines
  • Redesign of internal PicoPinFunction: getting rid of ugly switch case.
  • Examples for reading PWM
  • Example for watchdog
  • DMA support with examples
  • Implementation of namespace using pico_arudino
