But to really understand the chip, you have to read the Atmel datasheet (just search for 'ATtiny84 datasheet' on the net) - there is no way I2C is not a robust, long-distance bus, but rather is intended for inter-device communication within the confines of a circuit board. Pinout of ATtiny84 / 44 / 24 The pin-out diagrams for the ATtiny84, 44 and 24 are also identical. There is a 10 µF capacitor between the Die Pinoutschemata vom ATtiny85, 45 und 25 sind identisch. This one is different from the official one has it support ATtiny84. It receives data over the I2C line, parses it /* TinyWireS Library: ATtiny84A-Side (Slave) ----------------------------------------- INTRODUCTION ------------ The following sketch provides a simple example of setting up an ATtiny84A as an I2C Slave device This library enables members of the ATtiny family to become Slaves on an I2C Bus. Anyway, I'd try first using a common and tested I2C master (like arduino uno for example with wire library) with an attiny85 as slave. It is open-source and free to make for yourself The Attiny84 is a versatile and compact microcontroller that offers a good balance of features and power efficiency.
