This clock involves all the types of comunication between MCUs i know to use. It includes: i2c, infrared, paralel, 1 wire serial, and 2 wire serial (data bit-clock). Where does the hour come from??? To begin I used the DS1307 RTC to provide the h...

I started this project because I wanted some plug and play input and output modules for easy and fast prototyping of my electronics projects (mostly with PIC microcontrollers). Of course you can use leds and dip switches...

Connecting to the I2C network bus There are two I2C busses on the OOBoards, a local bus, and a network bus. The OOPIC code is essentially an interpreted language, ie the "code" is stored in EEPROM, and read/interpreted by the microp...
