Help arround USART communication Test both parts of the code (send and receive from PC) separately to see if both are working.
Add a single LED (with a 150-1000 ohm resistor to limit the brightness current...
Defeated by undefined reference to ... A DS18B20 is an inexpensive three-terminal TO-90 temperature sensor. The terminals are Vcc (+3.3--+5), gnd, and data. Data has a 4.7K ohm pull-up resistor...

Sorting algorithm The simplest way would be to rename the first ten elements from "test0..test9" to "test00 .. test09". Manually, if only 10 entries.
There is always a...
