Requirements

AtomVM has been tested with esp-idf v3.2.

Building AtomVM for ESP32

  • build:
cd src/platforms/esp32/
make

Note: GNU Make required

  • flash:
make flash

Running BEAM code on ESP32

  • BEAM module must be stripped before using PackBEAM:
./PackBEAM packed.avm module.beam
  • Packed BEAM module should be written to dedicated BEAM partition:
$IDF_PATH/components/esptool_py/esptool/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset write_flash -u --flash_mode dio --flash_freq 40m --flash_size detect  0x210000 packed.avm

Running Hello World

This example will print a Hello World message.

# Flash the hello_world.avm to the device
$ $IDF_PATH/components/esptool_py/esptool/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset write_flash -u --flash_mode dio --flash_freq 40m --flash_size detect  0x210000 build/examples/erlang/hello_world.avm

$ cd src/platforms/esp32

# Open the serial monitor
$ make monitor

Running Blink Example

This example will switch on and off a led connected to GPIO 2 every second.

Flash blink example using following commands:

# Flash the blink.avm to the device
$ $IDF_PATH/components/esptool_py/esptool/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset write_flash -u --flash_mode dio --flash_freq 40m --flash_size detect  0x210000 build/examples/erlang/esp32/blink.avm
