The function that executes when the user enters a menu often adjusts the encoder counts so that they will have certain default or saved values when the menu loads.Īn example of the back button is when the user goes from HSV color selection back a menu to select RGB color selection. The list contains a function to execute continually while that menu is being displayed, a function that runs when that menu is entered, and function to run when that menu's back button is hit.įunctions that run continually would be things such as updating the LED string when making the general shape of a new wand or band pattern. Each struct contains an array of other indices in the menu table corresponding to it's parent menu and submenus as well as a list of 3 function pointers. See Menus.h, each menu has a corresponding menu struct organized in a large menu_table. That cost can be drastically lowered if a sparser LED strip is used since that is the main expense (I used two strips of 144 LEDs 1m long). Read this documentation and if you still have questions contact me ( UI is not very intuitive which tends to happen when you are controlling complex LED patterns via three encoders and an LCD.ĭespite my attempts to keep the financial cost low I still ended up spending upwards of $100 on this project. Multiple fonts supported as well as bold and italizied versions of those fonts.Ĭoming soon! (hopefully) Upload any image and have the pixelstick display that image as it is moved at a constant rate.
Examples:ĭisplay any custom color on any portion of the stick (a wand).ĭisplay any pattern of colors or their repetition over the length of the whole stick (a band pattern).Īdd any custom string and display the text as the pixelstick is moved at a constant rate. The first company to make one is here: and they have an up and coming competitor here: but I built one myself for fun. It's a programmable LED strip for light painting (long exposure photography).
