Test firmware for the Area3001 anniversary badge.
Content:
- Download micropython for ESP32.
This firmware depends on the espnow feature of ESP. This is not yet available in 1.20.0
Download a Nightly build untill the espnow feature is in the release version - Flash the firmware to the badge using your favorite tool
See instructions on the download page - Copy the files inside the sources directory to the root of the ESP filesystem.
This can be done using Thonny, mpremote or other tools.
- On startup the ESP will listen for any packet containing a time value inside a JSON document. If such a packet is received within 3 seconds it will synchronize it's time value with the remote ESP.
- If no other devices are found it will assume a master role and start transmitting it's own time every second.
- if other devices are allready there it can do 2 things.
a) the other mac is larger: exit master mode, stop broadcasting
b) there is not higher mac: enter master mode - When the current master stops transmitting for more than 3 seconds all ESP's will enter master mode and broadcast their current time. The ESP with the highest mac address wins and becomes the new master.
The animation is devided in frames of each 33ms long (30FPS).
A every 33ms a function is called to draw a frame. the id of the frame is calculated by taking the modulus of the current network time devided by 33.
frame_id = (network_time // frame_length) % frame_count
Frame types that are currently implemented:
- solid color
- Color wheel. (left or right shifting)
Some ideas of frame types I like to add are: wheel that shifts in time, sparkle, gradient (moving or solid), chase and bounce.
In a future version I might be tempted to add regions that each have their own animaton, however I feel this is a bit overkill for now :)
