SoftwareWire hd44780 examples
|
|
==================================
|
|
|
|
These examples require that the SoftwareWire library be installed.
|
|
|
|
The SoftwareWire library can be installed using the IDE library manager.
|
|
SoftwareWire provides a Wire compatable library that allows the user to
|
|
configure pins for the SDA and SCL signals.
|
|
While it offers additional flexibility, it will not be as fast as using the
|
|
dedicated i2c h/w inside the microcontroller.
|
|
|
|
These examples use the hd44780 library hd44780_I2Cexp i/o class using
|
|
SoftwareWire instead of the Wire library.
|
|
|
|
Note: using a software Wire library is not necessary on the esp8266 platform as the wire library on that platform already provides a mechanims to change the pins used for i2c.
|
|
|
|
WARNING:
|
|
The SoftWareWire developers made a major change to the library June 2018
|
|
which is in the subsequent 1.5.1 release that causes it be unusable by
|
|
the hd44780 library.
|
|
Until this change is backed out, you will not be able to use
|
|
SoftWareWire beyond version 1.5.0 with the hd44780 library.
