I/O Card mit CC-Talk in C++

[login to view URL] This is the i/o card dikumentatio We need 3 implementations: Increase counter: Changepoints → C++ Native The app writes a file (any filename) to a defined directory with the contents: "NUM=VALUE". NUM would be the number of the register (0 to 3) and VALUE the number of counting steps to be increased. The native application monitors the directory (inotify) and reacts as soon as a new file has been created and finished writing. It increases the corresponding counter by the counting steps. After the counting steps have been incremented, the native application deletes the file. All files are processed, the oldest first: First In First Out. The directory must have permissions for the user "pi" rw. Money Deposit: C++ Native → Changepoints Once a verified and validated money deposit has taken place, the native application writes a file with any filename to a specific directory containing "VALUE:VERSION:HASH". VALUE is the cent amount thrown in. VERSION is a version number for this protocol (always 1 at the beginning). HASH is a control hash from an MD5 hash about the amount plus a password. For example: md5sum("[login to view URL]!!100") → 100 would be the cent amount. The directory must have rw permissions for the user "pi". Keystroke: C++ Native → OS If one of the hardware-keys is pressed, a keyboard event has to be triggered via the operating system. So key 1 should correspond to the output of the key XY of the normal keyboard. The hardware keys should be able to be intercepted via the keyboard event of a web browser (chrome).
