Debian prerequisites

sudo apt-get install libncurses5-dev flex bison gperf python-serial libffi-dev libsdl2-dev libmbedtls-dev perl

Compiling and flashing

git submodule update --init --recursive
source set_env.sh
make defconfig
make -j5

Optional configuration

make menuconfig

Compiling MicroPython

make -j5 -C micropython/mpy-cross
make -j5 -C micropython/esp32/

Flashing MicroPython

cd auto-flasher
cp ../micropython/esp32/build/application.bin firmware/sha2017-badge.bin
./auto_flash.pl /dev/ttyUSB0

Interacting via serial

make monitor

Building on OSX

First you have to replace the linux toolchain:

  • download the mac toolchain from this page
  • rename the linux toolchain: mv xtensa-esp32-elf xtensa-esp32-elf-linux
  • untar the mac toolchain: tar zxf ~/Downloads/xtensa-esp32-elf-osx-1.22.0-61-gab8375a-5.2.0.tar.gz

Then install the CP2102 usbserial driver

In the sdkconfig file change this line:

CONFIG_ESPTOOLPY_PORT="/dev/tty.SLAB_USBtoUART"

MicroPython

import badge
badge.eink_init()
badge.display_picture(0,-1)
import ugfx
ugfx.init()
ugfx.demo("HACKING")
ugfx.clear(badge.BLACK)
ugfx.thickline(1,1,100,100,badge.WHITE,10,5)
ugfx.box(30,30,50,50,badge.WHITE)
ugfx.string(150,25,"STILL","Roboto_BlackItalic24",badge.WHITE)
ugfx.string(130,50,"Hacking","PermanentMarker22",badge.WHITE)
len = ugfx.get_string_width("Hacking","PermanentMarker22")
ugfx.line(130, 72, 144 + len, 72, badge.WHITE)
ugfx.line(140 + len, 52, 140 + len, 70, badge.WHITE)
ugfx.string(140,75,"Anyway","Roboto_BlackItalic24",badge.WHITE)
