These are questions that we’re often asked: How is it better than ****** ? How is it different from ****** ? First of all you should not compare the Tinusaur powered by Atmel ATtiny85 microcontroller to things like Raspberry Pi (or any other platform running 32/64-bit RISK processor) or Arduino (running on ATmega or similar). In fact, the Tinusaur should … Read more
The Tinusaur Indiegogo crowdfunding campaign have just launched. Official link: https://www.indiegogo.com/projects/the-tinusaur-project-attiny85-quick-start-boards/ Short link: http://igg.me/at/tinusaur/ Please, support us. Questions? Don’t hesitate to ask them below.
The Tinusaur Project – ATtiny85 Quick Start Boards This is the name of our campaign. And is tarts tomorrow, Friday, February 26th. Please, HELP us produce more of these boards. Check also our Facebook page at https://www.facebook.com/tinusaur/
Yes, you read it correct. We’re planning an Indiegogo crowdfunding campaign for the end of this week. Why? We need some help to produce few hundred or more Tinusaur Boards and Tinusaur Bundles that we will keep in stock at our online store. When? It is planned for this Friday, February 26th, 2016. Like the … Read more
UPDATE about the online store: (1) Please note that this is the website of the Tinusaur Foundation – a non-profit association for public benefit, and we don’t have an online store; (2) The Tinusaur Boards and related products are offered by another organization, which is a business entity and has a website at https://tinusaur.com. As you may already know, last … Read more
As we’ve mentioned earlier (What is happening with this project?) we were working on shield-like add-on board for the Tinusaur Board. So here it is … It has only 2 LEDs and 2 resistors for each LED so no much to solder. This shield aims at 2 things – making it easier to … Solder 2 LED … Read more
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 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
In our previous post “USITWIX – Using UART as TWI / I2C” we looked at the USITWIX library that implements TWI / I2C communication between а ATtiny85 micro-controller and peripherals. Let’s see now how we can use that library to work with the BOSCH BMP180 atmospheric pressure sensor and a ATtiny85/Tinusaur boards. The BMP180tiny Library So, we wrote a simple library (called it BMP180tiny) that uses USITWIX to read and … Read more
As we know, there’s no I²C on ATtiny85, not even the TWI (Two Wire Interface, which is basically I2C with a different name) that some other Atmel chips have, so I had to write my own that takes advantage on the built-in USI unit. This library is called USITWIX and will be presented in this blog post. Of course, I used other people’s … Read more
