The OWOWOD Library

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

OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 3)

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

OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 2)

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

OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 1)

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
