A SUMP compatible Logical Analyser for the NucleoF401RE (STM32F4xx) almost up to 10MSPS, 8Ch, 32K samples memory. This will turn any NucleoF401RE (will work with other boards but it was not tested) system into a Logical Analyser compatible with a subset of the SUMP protocol. It can be used with clients such as PulseView, sigrok-cli, and LogicSniffer. While it is not as feature complete as other products, such as the OLS, it can turn that STM32 board that is lying around into a no frills, bare to the bones, logic analyser. Sampling rate up to 500KSPS should work on most platforms. Higher than that, only the F401RE, or other similar >84Mhz platform should provide results with accurate timing measurements up to 5MSPS. 10MSPS will be accepted but do not trust timing information as the board cannot really keep up with this speed. However this sampling rate can still be usefull. If you wish to add support for other platforms, please focus in creating the appropriate unrolled loops callibrated with an osciloscope. PORTB is current used, and Pins PB_0 to PB_7 are reported. Unfortunately these pins are scattered over the board and are not contiguous. Check this diagram to find them. This implementation was based in the mbed environment in order to increase its compatibility, as new targets are expected to be supported. The focus of this implementation is compatibility and extensibility, and not only performance.
