+# libopencm3
+
+[libopencm3](http://libopencm3.org/) is an Open-Source lowlevel hardware
+library for ARM Cortex-M3 microcontrollers (but also M0, M4 are supported and
+more to come).
+
+[Seb Holzapfel](https://github.com/schnommus) has been working on extending
+libopencm3 to support the EFM32HG and currently has currently tested on the
+Tomu using a Linux host:
+
+ * A USB-Serial CDCACM device example (`usb_cdcacm`)
+ * A USB HID mouse emulation example (`usb_hid`)
+ * A USB Mass Storage Device example (`usb_msc`)
+ * A USB MIDI example (`usb_midi`)
+ * A raw endpoint example with a sample python program that controls an LED
+
+The plan to push these changes upstream (to libopencm3) in the near future but
+for now you can find a copy in the
+[I'm Tomu GitHub organisation](https://github.com/im-tomu).
+
+ * [libopencm3 with SiLabs EFM32 Happy Gecko + Tomu support.](https://github.com/im-tomu/libopencm3)
+ * [libopencm3-examples with SiLabs EFM32 Happy Gecko + Tomu support.](https://github.com/im-tomu/libopencm3-examples)
+
+FIXME: Typing `make` should eventually download and compile these examples for
+you.
