ABOUT
Bot Terminal: a crossplatform utility that performs binary data exchange via serial port.It allows one to set up flexible rules about how to reply to different requests. DOCKER: PRINTABLE QUICK REFERENCE (CHEAT SHEET) The appearance of the card is largely inspired by the GDB Quick Reference: I was using it for a long time already, and it was a very pleasant experience. It is clear and concise. Personally, I just print it on both sides of a single A4 sheet. The card is written in LaTeX. Not everything was smooth. UNIT-TESTING (EMBEDDED) C APPLICATIONS WITH CEEDLING Unity is curiously powerful Unit Testing in C for C. It aims to support most embedded compilers, from 8-bit tiny processors to 64-bit behemoths. Unity is designed to be small, yet still provide you rich expressive assertion set. CMock. CMock is a utility for automagical generation of stubs and mocks for Unity Tests. OBJECT-ORIENTED TECHNIQUES IN C For that to be done, OO-approach comes to the rescue. We want to have object Crc which has two methods: byte_feed (uint8_t byte) : feed next byte; value_get () : get current crc32 value. Since C doesn't support object-oriented programming, we have to manually pass pointer to the object for which method is called. TNEO RTOS
TNeo RTOS. TNeo is a well-formed and carefully tested preemptive real-time kernel for 16- and 32-bits MCUs. It is compact and fast. TNeo was born as a thorough review and re-implementation of TNKernel v2.7.

To run the application, clone the repository, cd to it, and run the following: npm install bower install. Now, you can start the application.
VIMPRJ
Usage. Usage of this plugin is quite easy. In the root directory of your project, you need to create new directory .vimprj and put any number of files *.vim inside. Every time you open new file in Vim, plugin looks for .vimprj directory up by tree, and if it is found, then all *.vim files from it will be sourced.

Bot Terminal is a crossplatform utility that performs binary data exchange via serial port. It allows one to set up flexible rules about how to reply to different requests. So, it listens for data, parses it, and replies as necessary. I developed this tool in order to reverse-engineer various binary protocols of car ECUs (Engine Control Unit).

VIMPRJ
Usage. Usage of this plugin is quite easy. In the root directory of your project, you need to create new directory .vimprj and put any number of files *.vim inside. Every time you open new file in Vim, plugin looks for .vimprj directory up by tree, and if it is found, then all *.vim files from it will be sourced.

It allows us to create a text file like this: STANDARD INTERFACE BETWEEN A TEXT EDITOR AND AN IDE The thing is that IDE should not include text editor. Well, it might include one, just to be more self-contained, but the text editor shouldn't be a major part of an IDE: instead, there should be an interface that both parties (IDEs and text editors) should agree on.

Hi, my name's Dmitry Frank. I'm a passionate software engineer with strong background in low-level parts of the stack (MCU real-time kernels, C, Assembler), and experienced in higher-level technologies as well: Go, C++, JavaScript, and many others. Author of well-formed and carefully tested real-time kernel for 16- and 32-bit MCUs: TNeo , which is now used by several companies, including the car alarm company StarLine LLC . I'm constantly learning new stuff, and I love to write well-formed and maintainable software. There are two things that I probably love more than anything else (apart from my family, of course) : nature and good software. It may sound strange, but I love them so much so that I often identify each of them with one another. And, of course, I strive to write my own software so that it is as beautiful and elegant as nature is. Easier said than done, though. If you want to contact me, email is probably the best. My PGP key: dmitryfrank.asc . I'm also on GitHub , Stack Overflow , LinkedIn
