micropython-esp32-ulp 1.2.0

Features

The following features are supported:

• the entire ESP32 ULP instruction set

• constants defined with .set

• constants defined with #define

• expressions in assembly code and constant definitions

• RTC convenience macros (e.g. WRITE_RTC_REG)

• many ESP32 ULP code examples found on the web will work unmodified

Quick start

To get going run the following directly on the ESP32:

# Step 1: Install micropython-esp32-ulp
# IMPORTANT: Ensure the ESP32 is connected to a network with internet connectivity.
import upip
upip.install('micropython-esp32-ulp')

# Step 2: Run an example
# First, upload examples/counter.py to the ESP32.
import counter

The examples/counter.py example shows how to assemble code, load and run the resulting binary and exchange data between the ULP and the main CPU.

Documentation

See docs/index.rst.

Requirements

The minimum supported version of MicroPython is v1.12.

An ESP32 is required to run the ULP machine code binary produced by micropython-esp32-ulp (the ESP32-S2 will not work as it is not binary compatible with the ESP32).
