It is an assembler toolchain for the ESP32 ULP (Ultra Low-Power) Co-Processor, written in MicroPython.

The goal is to be able to translate small assembler language programs to a loadable/executable machine code binary, at runtime, on the ESP32 microcontroller, from projects implemented in MicroPython.

This is intended as an alternative approach to assembling such programs on a development machine using the binutils-esp32ulp toolchain from Espressif.

Work in progress and not really practically usable yet.

Please be patient or contribute missing parts or fixes.
