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
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
So far we’ve used a LED as output to produce light of different colors and intensity (Tutorial 001 and Tutorial 002) but we haven’t generated any sound yet. In fact, that isn’t very difficult to do. We will use a buzzer for output. According to Wikipedia … the buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, … Read more
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
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. Finally! All the parts were received … Read more
The first official Tinusaur workshop took place last Sunday (on the 14th of December) in the Veliko Turnovo University “St. St. Cyril and Methodius”. It was really great! The workshop was attended by 22 people of age 16 to 44. As you may have guessed already it was for the absolute beginners so we first learned how to … Read more
In my previous post “OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 1)” I wrote how to get a proper reference signal from a serial communication using USB-to-Serial TTL converter. The next steps are to generate the same signal but programmatically using the ATtiny85. And this is what I did … … Read more
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
