UPDATED: DS1307 Library

The functions were moved to separate files in the DS1307tiny library. The sample code in the ds1307tiny_test1 module looks cleaner now. The output should be something like this … Note that one of the challenges working with a real-time clock the the DS1307 is to set it up with the correct time at the beginning. One way is to … Read more

Working with DS1307 Real-time Clock and ATtiny85 using USITWIX Library

DS1307 Serial Real-Time Clock USITWIX Tinusaur.

Working with the DS1307 Serial Real-Time Clock using the USITWIX library for I2C / TWI on Atmel ATtiny85 / Tinusaur. Let’s see how can we work with the DS1307 serial real-time clock using the USITWIX library for I2C / TWI on Atmel ATtiny85 / Tinusaur. Bellow is the testing setup. NOTE: We need the USB-to-Serial … Read more

OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 3)

It is time now to write a library that will use the Debugging Output. In the previous 2 articles about OWOWOD we managed to generate proper serial signal and start sending characters out observing  the result on an oscilloscope. (see previous articles Part 1 and Part 2 for reference) The functions we have so far are: … Read more

OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 1)

I always wanted to be able to write something like this in my code … have that running on the micro-controller and see the debugging output on my computer. The Problem Unfortunately that is not easy – in fact not possible with the standard tools used to work with the ATtiny85. The problem is this: (1) those … Read more

MAX7219 driver for LED Matrix 8×8

UPDATE 2022: The MAX7219LED8x8 library, now renamed to MAX7219tiny has now a new home at tinusaur.com/libraries/max7219tiny. Check also this MAX7219 & ATtiny85 tutorial to learn how the library works. MAX7219LED8x8 is a C library for working with the MAX7219 display driver to control 8×8 LED matrix. It is intended to be used with the Tinusaur board but should also work with any other … Read more

TinuDHT – ATtiny Library for DHT11

Ever wanted to do a project with that cheap DHT11 temperature/humidity sensor and did not want to go the Arduino way but with a simple ATtiny85? You probably know already about  the issues with the existing Arduino based libraries running on the ATtiny microcontrollers, but can’t deal with them. TinuDHT is our answer to this. TinuDHT is a … Read more
