Use a 32ch RTRobot servocontroller with USB/UART

 
Here's the board I used :



A cheaper and more accessible version of Lynxmotion controller board. For this one you have to initialise it before using it (There is no documentation about that, i had to find it myself, so to save your time here is it).

You have to send these first :
ASCII : ~RT~OL
HEX : 7E 52 54 7E 4F 4C

You will receive this response from the controller :

ASCII : RT
HEX : 52 54 17

At the end of every command sen you have to include "\r\n".
