 The dsPIC can be programed using the picpgm software which is [http://picpgm.picprojects.net/index.html hosted here].

 The pin number (pin="xx") corresponds to the GPIO pin number on the Raspberry Pi (see figure in [[#dsPIC 33F|dsPIC 33F]] section).
 The configuration example shown above is the one used to program the dsPIC of the World Pendulum Alliance.
