Map values from one range to another range in a simple way. This is not a true algorithm but helped me a lot to save time. This mimics the Arduino Map function. See https://www.arduino.cc/reference/en/language/functions/math/map/

B4ASnippetLogging/Exceptions [ROOT]

Log to USB [Root]

The `Log2USB` function is designed to facilitate logging within Android applications by writing log entries to a text file (`SystemLog.txt`) located on the first accessible USB drive without Userinput. It requires root access due to its use of the `SuShell` component to execute Unix commands.

B4ASnippetNFC

MiFare Classic Buspass

There was a time when NXP''s Mifare Classic NFC tags were the go-to card for, among others, bus, metro and train passes, hotel keys, club memberships, etc. They offered security of a sort which required keys to access the tag''s memory. Due to discovered security flaws, however, its day has mostly passed. Nevertheless, reading from and writing to Mifare Classic is an interesting exercise, and we still see some interest here on the forum from time to time.
