pitrix
What is pitrix?
pitrix is a software to run on an ESP8266 microncontroller connected to a LED matrix. It will display the time and a few other nice effects and stuff.
pitrix fetches the current time via NTP, is controllable via MQTT and can be flashed over-the-air, so you don't need to disassemble your nice-looking LED matrix everytime you want to update the software.
How to use
Checkout the code, rename include/config.sample.h
to include/config.h
and edit it to match your preferences / environment.
Then compile and flash it, preferably using PlatformIO.
Control it
Currently, control is possible via MQTT and / or HTTP REST API.
To use MQTT, you have to define MQTT_ENABLE
and configure your MQTT sever's credentials. MQTT_TOPICis set in
include/config.hand defaults to
pitrix`.
To use the HTTP REST API, you have to define HTTP_SERVER_ENABLE and set a port number to listen on (80 is set by default).
Possible commands / topics are:
MQTT_TOPIC/mode
/POST /mode
lets you select an effect to show. Seesrc/effects.cpp
for a list. Default effect iscycle
, which will cycle through some of the available effects. Another effect isoff
, which will just display black, effectively turning the display off. (pitrix stays running, so you can turn it on again by simply selecting another mode.)MQTT_TOPIC/brightness
/POST /brightness
sets the brightness of the display. Valid values are between 1 (darkest possible setting) and 255 (maximum brightness).MQTT_TOPIC/reboot
/POST /reboot
reboots pitrix. Send any value.
You can set retained values to have pitrix read them at startup, effectively
setting a default effect or brightness. (Do NOT set a retained value for
MQTT_TOPIC/reboot
unless you want pitrix to reboot all the time.)
Monitor it
The current status ("ONLINE" or "OFFLINE") of pitrix will be set at
MQTT_TOPIC/status
.
If you enabled MQTT_REPORT_METRICS
, metrics are sent via MQTT every 15
seconds:
MQTT_TOPIC/free_heap
contains the free heap memory in Bytes.MQTT_TOPIC/uptime
contains the uptime of pitrix in seconds.MQTT_TOPIC/fps
contains the currently reached frames per second.
If you enabled HTTP server, you can always make GET requests to /free_heap
, /uptime
or /fps
to get those values.
If you enabled DEBUG
, log messages will be sent to MQTT_TOPIC/log
.
