raulsr988 0:f8a72cc60181 17 *
raulsr988 1:3b3e8f8352a8 18 * First you need to program the firmware to the MBED <br>
raulsr988 4:f27d1844c17a 19 * You can use the online compiler (https://studio.keil.arm.com) to compile the firmware and stored it on the flash mbed memory<br>
raulsr988 0:f8a72cc60181 20 * Steps:
raulsr988 0:f8a72cc60181 21 * - Change the "id" of the device corresponding to the hand used (right-hand: ID 65, left-hand: ID 64) <br>
raulsr988 1:3b3e8f8352a8 22 * - Press "Compile" and save the .bin file on the flash mbed memory <br>
raulsr988 3:f31b6ddb9cd3 23
raulsr988 0:f8a72cc60181 24 * - If you want to check the correct functionality, you can connect the mbed to the serial USB and with a serial monitor program (configured with a baudrate of 115200), see the CAN messages information of the hand. <br>

raulsr988 0:f8a72cc60181 28 *
raulsr988 1:3b3e8f8352a8 29 * Running "launchManipulation" application, you can open or close the hand with this parameters (assuming you know how to run "launchManipulation"): <br>
raulsr988 2:8ebb11ba21be 30 * set pos 6 1200 -> open hand <br>
raulsr988 2:8ebb11ba21be 31 * set pos 6 -1200 -> close hand <br>
raulsr988 2:8ebb11ba21be 32 * set pos 6 0 -> loose hand <br>
