Launching Crowdfunding Campaign in January

Tinusaur OLED SSD1306xLED Crowdfunding Campaign

It looks like that our most popular software library is the SSD1306xLED. This is a library for working with OLED displays based on the SSD1306 controller. So, we decided to create a Tinusaur shield to carry an OLED display and we’re thinking about putting it up for crowdfunding this January. What could you do it … Read more

Working with BMP180 Pressure Sensor and ATtiny85 using USITWIX Library

USITWIX – Using USI as TWI / I2C

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

New Library: USITWIX – Using USI as TWI / I2C

Attiny85 Tinusaur USI TWI I2C BMP180 Variometer

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

ATtiny85 and ESP8266 – do you really need that?

Tinusaur ATtiny85 ESP6288 Shield

Yes, why not. And here is what I did … (this will be series of posts about what I did with ATtiny85/Tinusaur and ESP8266 WiFi module) First, what could be accomplished with such limited device as ATtiny85? It has 8 pins, 2 of which are for the power (Vcc and GND), one for the RESET … Read more
