PCF8574 library. i2c digital expander for Arduino, Raspberry Pi Pico and rp2040 boards, esp32, SMT32 and ESP8266. Can read write digital values with only 2 wire. Very simple to use and encoder support.
Add the possibility to insert address at begin()
Add support for Arduino UNO R4
Fix STM32 support and add support for Raspberry Pi Pico and other rp2040 boards
Add support for custom SERCOM interface of Arduino SAMD devices. Force SDA SCL to use GPIO numeration for STM32 bug (https://www.mischianti.org/forums/topic/compatible-with-stm32duino/).
Force SDA SCL to use GPIO numeration (https://www.mischianti.org/forums/topic/cannot-set-sda-clk-on-esp8266/).
Fix the SDA SCL type #58 and add basic support for SAMD device.
Fix example for esp32 by force u32 type, and double begin issue #56 to maintain a reference for end transmission.
I add this versione to try fix the platformio crawler
Fix package size to reduce download dimension, encoder management some additional algorithm check the documentation, and structure
Minor fix and remove deprecated declaration
