#!/usr/bin/env python
# ui_remote.py - naive script to poke and prod the altimeter firmware over
# GDB/MI. Useful for rapid UI development/testing, all while probably not being
# strictly threadsafe. We're not triggering an ISR on the remote, so PC could
# already be in the middle of an ISR when we fire a UI event, which should
# never be allowed to happen in normal use.
# Useful nonetheless.
#
# FIXME allow smarter queueing of UI events in this script so they can be
# batched into the same (slow) interrupt-and-continue window.
