MICROCONTROLLER PROGRAMMING.pdf
The timer peripheral is used to generate time bases by counting up or down from 0 to a programmed value. It has a 16-bit counter register that counts up/down at a rate determined by the timer clock frequency and a programmable prescaler value. The prescaler divides the timer clock to produce the counter clock. The auto-reload register determines the period of the time base by reloading the counter when it reaches this value, restarting the counting cycle. This allows the timer to generate periodic interrupts or trigger events at the programmed time intervals.

I2C Drivers
The document discusses Inter-Integrated Circuit (I2C) drivers in Linux. It covers I2C protocol basics like start/stop conditions and transactions. It then describes the I2C subsystem in Linux including I2C adapter, client and core drivers. It also discusses registering I2C devices without and with device tree, and provides examples of I2C client drivers.
Linux System
The document provides an introduction to the Linux operating system. It discusses the basics of Linux usage, including directories, shells, files, users and permissions. It also covers installing Linux, using the Vim text editor, and the X86 booting sequence. The goal is to give readers an overview of the Linux system and how its core components work.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
