2000 USD DLC Memo for Windows CE
Desktop Apps
Programme for the monitoring and monitoring of fast-powered products.
Despite this prosaic name, I had to face difficulties. First, it is multi-user and stores information in the cloud. And to connect with the cloud, #https is used, which does not work normally on most old machines. It had to be done so that it worked. Secondly, it can also be used offline, without connection to the cloud. And this means - local database and synchronization with cloud storage when re-connection. Third, low screen resolution, limited memory volume and processor performance on target devices did not contribute to a comfortable development. The main time and effort went on to create an acceptable UI.
It is designed for one French startup, so it supports French and English.
It is written in C#.

SkyPark devices configuration protocol
Desktop Apps
A setup control system for devices on the #AVR microcontroller.The approach described in the document AVR105 (self-programming) is used.Simply speaking, this thing allows you to quickly change a number of constant parameters in the microcontroller sprinter without having to overflow the whole sprinter.The system includes a built-in browser library and two client programs, one for #Windows and the other for #Android.Thus, you can manage the settings of devices on microcontroller from a laptop or from a smartphone.Supported communication channels are #COM-port, #USB and #Bluetooth.The built-in library provides user authentication and access levels.Therefore, even possessing a laptop or smartphone with a client program, a stranger or person without authorization will not be able to connect to the device and influence its work.The billiothec is written on #C with assembly inserts, the client program for #Windows - on #Freepascal, the client program for #Android - on #Java.Developed for one of the Ukrainian firms using microcontroller #AVR in their attractions devices.

Softick Card Export for Windows CE/Windows Mobile
Desktop Apps
I worked on this development in the 2000s.The software has emulated the #USB Mass Storage protocol, allowing to convert the #WindowsMobile (the predecessor of modern smartphones) to a #USB cartrider.The emulation of the #USB Mass Storage protocol did not present any particular difficulties.The difficulty was to download the original #USB ActiveSync driver, which was written in the assumption that it will never be downloaded and replaced by something else.When he was charged, he just dropped into the system.And I still had to make this forced loading reversible... Here’s where the fun began!This product was popular and the hackers constantly broke it.I had to fight the hackers.The end was that I developed a preprocessor that processed the program’s source code in the #C language, after which the result of the compilation processed by such a preprocessor of the program was much worse subject to analysis and re-development by the hackers.This program is written on #C with assembly inserts and uses technology of the type of capture of functions and capture of other programs.
