A library to drive Feetech's STS smart servos - in particular the STS 3215. This low-cost servo offers very interesting properties at a quite cheap price (approx. $15 at the time of writing):
This library was made mostly with simple, "Hello World" applications in mind. Thus, its high-level API only provides access to the main, basic functions. However, all commands and registers are exposed, thus more complexe applications can be easily written from it.
