Hi !
I'm working in a personal project with arduino, so I had to develop or modify some existing libraries. That may be of interest to anyone so I don't know how to share them in playground or somewhere other place.
The libray list is:
MC14499:
A controller to a 4 digit 7 Segment LED display, using the MC14499 controller with a serial protocol.
Keyboard:
An object abstraction layer to define multi button keyboard using one analog input. It supports short and long keypresses and debouncing. Pin used, number of keys and timings are configurable.
Timer:
Define 3 types of timers, astable, monoestable and retriggerable. I use them along with timer2 to implement task schedulers in real time environments.
Rtc_Pcf8583:
An adaptation from Rtc_Pcf8563 library, to work with Pcf8583 timers.
if someone is interested may contact me.
