Not sure, but it certainly lowers the bar for developing code for the ULP, and ULP support is a essential feature not a nice to have, esp. if you want a battery powered device. The code/debug/test cycle is much faster with the python assembler, as theres just one file to copy to the target, which given the lack of visibility of the ULP code, really helps development (esp. as the ULP binary is functionally very closely coupled to the python code that launches and talks to it) Until/unless someone integrates the esp-idf ULP compiler into the build scripts, Thomas Waldmann's assembler seems like a great approach. Even then, the one file binary+python ULP update makes it preferable IMO. |

Adds support for loading and running ULP code (taken from Andreas Valder's PR to Damien George's MicroPython) together with Thomas Waldmann's micropython ULP assembler.
ulp_count.py included as simple usage example
pulse_counter.py shows use of GPIO by ULP to debounce a noisy pulse stream
