Our SSD1306xLED library works well with the SSD1306 displays, it is small as binary code and is very fast. But, there was a problem … Several months ago we ordered some displays from the Far East and we expected them to work just fine. Unfortunately, they did not. And the problem was not in our … Read more
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. The MAX7219 controller manufactured by Maxim Integrated is a compact, serial input/output common-cathode display driver that could interface microcontrollers to 64 individual LEDs, 7-segment numeric LED displays of up to 8 digits, bar-graph … 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
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
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
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. The MAX7219LED8x8 library uses now a simple scheduler to automate the task of outputting the buffer to the LED 8×8 matrix. This is not like a real task scheduler (in … Read more
