As an SX Beta Tester, one of the cool things is to try out new features of SX/B. One of which is a new feature to allow SX-28 arrays to be larger than 16 bytes. This brought up a great idea to take the RobOylmpic design and modify it somewhat to work with a larger array like 40! Jonny Mac (Jon Williams) wrote wonderful code to demonstrate the new RobOlympic badges (Badge.sxb) found on the Parallax website. However, my design allows for his program to run (modified) for a large 8x40 LED display made up of (5) 8x8 LED Matrix modules for a 40 column display. This code will go even further {in future releases} to also display the scrolling text and graphics in 3 colors (Green, Red and Yellow). This is unfinished code - but along with the 3 pages of 11x17 schematics, it offers great possibilities in the near future. Currently this code is set up to run 1 colored 16 columns which is 1 more than the Robolympic Badge did at 15 columns. The dispBuf array is set up to be 1 more than the column length of the display (in this case 17). I will add more 4017 cascaded circuits soon to demonstrate a full 40 column display. PS: I got permission from Ken for this feature SX information release. See the attached code for single colored LED Matrix at 16 columns as well as the 3 pages of schematics in my design. As you can see the code has very little change to JonnyMac's original code - so far (modified currently to run under cascaded 4017 decade counters ICs instead of 4028 ICs). The 8x8 BiColored LED Matrix's I used I bought on Ebay (They are always listed - Sure Electronics I beleive - China?) - Cheap for < $20 for 10 including shipping!! When ready I will post some pics, video (YouTube), etc. More updates to come soon!! ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=211040 Need assistance?
