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.
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
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
OWOWOD is One Wire / One Way Output for Debugging library. It allows you to output text from the Tinusaur (ATtiny85 microcontroller or other similar), though USB-to-Serial or TTL converter (based on PL2303, CH340G or similar) and to the computer screen using COM port monitoring tool. Why one would need something like that? It would’ve … Read more
The second Tinusaur workshop took place last Saturday (on the 14th of February) in the Veliko Turnovo – University “St. St. Cyril and Methodius”. We first taught soldering with some simple kits for the most inexperienced and the Tinusaur Starter for others. Then we wrote few simple programs – blinking LED and making sound with buzzer. The youngest were 2 … Read more
UPDATE: Please, check the most recent post about this library at /tag/ssd1306xled After playing for awhile with that SSD1306 OLED display I decided to add few more things to the SSD1306xLED library and the ability to print numbers seamed to be an important one. There is already a function in the library that outputs strings so I … Read more
