Hardware
Protocol
Protocol is called LMCP (LedMatrixControlProtocol) Works via UDP port 1337
Command format: uint8_t command: the command [uint8_t data ...]: the data (can be non-existant) Multiple commands can be sent in 1 datagram (optional). Commands: 0x01: write buffer, writes the current framebuffer to the screen no arguments 0x02: clear, clears the matrix and writes the current framebuffer to the screen no arguments 0x10: draw rows * uint y: y position of the row to draw (0-5) * uint8_t data[96*8]: send the data for 8 rows at a time, position is y * 8 0x11: draw image rectangle * uint8_t x: top left x position of pixel data * uint8_t y: top left y position of pixel data * uint8_t width: width of pixel data * uint8_t height: height of pixel data * uint8_t data[width * height]: pixel data 0x20: write text line based chars are 5x7 -> 6x8 including space and line separation * uint8_t x: top left x position in chars (0-15) * uint8_t y: top left y position in chars (0-5) * uint8_t brightness: brightness of text (0x00-0xFF) * [uint8_t text[...]]: text (ascii) * 0x00: terminator 0x21: write text absolute * uint8_t x: top left x position in pixels (0-95) * uint8_t y: top left y position in pixels (0-47) * uint8_t brightness: brightness of text (0x00-0xFF) * [uint8_t text[...]]: text (ascii) * 0x00: terminator 0x30: draw rows RGB * uint y: y position of the row to draw (0-5) * uint8_t data[MATRIX_WIDTH*8*3]: send the data for 8 rows at a time, position is y * 8 0x31: draw image rectangle RGB * uint8_t x: top left x position of pixel data * uint8_t y: top left y position of pixel data * uint8_t width: width of pixel data * uint8_t height: height of pixel data * uint8_t data[MATRIX_WIDTH * MATRIX_HEIGHT * 3]: pixel data (RGB24) 0x32: set compatibility color * uint8_t r * uint8_t g * uint8_t b
