# Deploy the chatter binary to the tablet and run it on the e-paper display.
|
||
|
|
#
|
||
|
|
# Usage: scripts/deploy-and-run.sh [path-to-binary]
|
||
|
|
# default binary: build/chatter
|
||
|
|
#
|
||
|
|
# Requires: `ssh chatter` working (see doc/tablet_access.md).
|
||
|
|
#
|
||
|
|
# IMPORTANT lessons baked in here:
|
||
|
|
# * The e-paper framebuffer is a singleton guarded by an flock
|
||
|
|
# (/tmp/epframebuffer.lock). Only ONE process may hold it. A stranded
|
||
|
|
# instance blanks the panel for everyone, so we always stop the previous
|
||
|
|
# chatter unit first.
|
||
|
|
# * Launch as a transient systemd service (systemd-run), NOT an ssh background
|
||
|
|
# job: that detaches cleanly (no held SSH channel) and is stoppable via
|
||
|
|
# `systemctl stop chatter`.
|
||
|
|
# * xochitl owns the display while running, so stop it first (pre-authorized
|
||
|
|
# during development). Run scripts/restore-xochitl.sh to bring it back.
