| - | ===== RS232 Controller ==== | ||
| - | An Arduino based RS232 controller for two [[http://www.waveplayer-systems.de/|Waveplayer8]].\\ | ||

| - | ==== Code ==== | ||
| - | For the code I needed a little bit of reverse engineering.\\ | ||
| - | {{:arduino_boards:reverse_rs232.jpg?400|}}\\ | ||
| - | To control the Waveplayer8 one has to send a CRC control byte. The polynom that is used is: 0xD5. The code to calculate the CRC byte was in the [[http://www.waveplayer-systems.de/WavePlayer8%20Beschreibung%20V3.pdf|manual]]\\ | ||
| - | The controller plays random files and pauses depending on the value of a potentiometer.\\ | ||

| - | === Customize the Arduino Code === | ||
| - | One can change the length of the pause (in seconds):\\ | ||
| - | unsigned long longest_pause = 100; | ||
| - | The track number:\\ | ||
| - | int number_of_tracks = 8; // number of all tracks | ||
| - | And in an array one can write the individual length of each track (in seconds):\\ | ||
| - | unsigned long length_of_tracks[] = {11, 12, 13, 14, 15, 16, 17, 18}; | ||
