ledpijp

71 APA-102 LEDs mounted in a hornbach fixture, driven by an esp-8266

my implementation of ledspace but with a faster-booting controller board

wifi

• tries to connect to the ap credentials defined in code
• if it can't connect within 10 seconds* since boot, it will flash blue and green, then create a network with the name ledpijp and the password defined in code from the original access point

* 10-second time limit is configurable in code as WIFI-GIVEUP

interaction

• visit the IP of the ESP-8266 in a browser
• select the animation you want
• inspect the page source, reverse engineer the API routes

specs

• tries to approximate 60 Hz refresh rate

todo

patches welcome

• API route to get currently chosen animation
• increase and decrease brightness at runtime
• strobe light
• API route to get brightness
• API route to get speed
• show the correct speed slider depending on animation
• fix reset button
• start animation immediately, don't wait for internet
• rainbow density=0 should freeze rainbow, not fade to a solid color
• save last animation in nvram
• save brightness in nvram
• save speed in nvram
• API route to allow arbitrary solid-color switching (for now, this is possible by using cycle mode, slowing it down, then slowing it to zero when it's showing the color you want)
• more animations
• use the onboard (H)SPI functionality of the ESP-8266
• use NTP syncing to switch animations depending on time of day
• redshift-style animation that darkens in the evening and brightens in the morning
• API route to allow fully custom animations using a simple intrepreted language or expression
• use a more serious template for HTTP responses
• minimal css styling for GET /
