I've been playing around with this display a bit and I agree that the code supplied has limited functionality.However I've created an interrupt driven version of the code that constantly scans an 8x32 byte array to address each pixel on the board with ease. Please use any part of this code you guys like.
Global variables use 1589 bytes (77%) of dynamic memory, leaving 459 bytes for local variables. Maximum is 2048 bytes.
Hi, may be anybody can help me. My trouble in shoing text at led matrix. It shows in inverse mode, WHITE TEXT IN RED BACKGROUND but normally must RED TEXT IN WHITE BACKGROUND, have you any ideas?p.s. i'm using LED matrix 16x64 and arduino nano and Dancopy's shortened_Final_Code_A.ino sketch image for example
HelloThank's to Kaziewip for your program, it work perfectly !!But i have a probleme with my LED Matrix.My counter work well, but i have a lot of blinking artefact on the screen:You know why ?
With the help of all here I have managed to drive the 64x16 display by WIFI from a serial string in a terminal in a Linux box (Raspberry Pi) or Mac OSX.The Arduino receives serial data and displays 8 characters on the top half as a static display and then a string that scrolls along the bottom half.This can be fed from a serial program but I now use and ESP8266 to receive the data by WIFI from a box on my LAN.This is very crude since I program by copy - paste - pray. (Thanks!)EDIT - now multimodeTwo lines of fixed 8x8 charactersTop line of fixed 8x8 characters - bottom line scrollingOne line of scrolling 16x8 charactersOne line of fixed 16x8 charactersDownload from here http://www.sunspot.co.uk/Projects/displays/LEDmatrix16x64/LEDmatrix16x64.htmlI hope to add a graph using the draw rectangle code.
