Control transfers can transfer less than was requested by the host in the wLength field. if this short transfer is a multiple of the endpoint's packet size, a zero length packet must be sent. Adds tests for a range of control transfer IN requests, and properly supports this in the core. Based heavily on work by Kuldeep Dhaka. See https://github.com/libopencm3/libopencm3/pull/505 and https://github.com/libopencm3/libopencm3/pull/194 for original discussion. Tested with stm32f4, stm32f103 and stm32l053. |

README.md
This project, inspired by usbtest and the linux usb gadget zero driver is used for regression testing changes to the libopencm3 usb stack.
The firmware itself is meant to be portable to any supported hardware, and then identical unit test code is run against all platforms. This project can and should be built for multiple devices.
Requirements: pyusb for running the tests. openocd >= 0.9 for automated flashing of specific boards python3 for running the tests at the command line.
You will need to modify the openocd config files, as they contain specific serial numbers of programming hardware. You should set these up for the set of available boards at your disposal.
Tests marked as @unittest.skip are either for functionality that is known to be broken, and are awaiting code fixes, or are long running performance tests
An example of a successful test run:
