Have this code, kicking around in my library, may be useful if your programming the 8x8 led matrix's 7 x 5 characters, take note of the kerning value if you want to develop proportional spacing ' 5x7 Character Set with kerning number ' License: use and abuse for whatever you want Data &B00000000,&B00000000,&B00000000,&B00000000,&B00000000,&B000 00000,&B00000000,6 ‘ Space Data &B10000000,&B10000000,&B10000000,&B10000000,&B00000000,&B000 00000,&B10000000,2 ‘ !

2014-08-18_001838_charset.zip take note the 6th data value seems to have a space in the code above when publishing - I have included a zip by the way a kerning value example is if it is 6 then use 6 columns, if its 4, then 4 columns etx |

Hi David, I am assuming that this is for use with the max7219 driven 8x8 led matrix? If so, can you post any code as to how the table is implemented using a uMite? Thanks!!!! |

Jim, Intention was to use this character set for scrolling display using max7219 8x8 leds about 10 of them joined together I haven't got any further as yet, may get back to it though in next couple of months once I finish couple of my projects Have a look at the following arduino site, it would be great if someone could create a library of routines for us all max7219 commands like matrix "The Quick Brown Brown Fox...", Scroll matrix "Hello World",Flash etc 7Sement "57.66" 7Segment "The Quick Brown Brown Fox...", Scroll" ' I've seen a character set for 7-segment somewhere on the web regards David |

Hi, just hooked up a max7219 8x8 led matrix to spi on WW44 board. So far so good. I used one of the data files in this thread for the letter "A" and turning on and off individual led in the matrix, kind of fun to learn, especially when it works. So my question is to those that have used these for a project... I am using MMedit and whenever I load a new program into the uMite, the matrix does some weird random things during the loading process. Not a big deal but Have you noticed this also? Just a note, I am amazed at how fast these work. Granted I am only playing with one 64 led unit, but at spi speed at 10mhz and cs pulse at .1, these things and the uMite really rock. |

Jim, Glad you could found some use for the data. If you have something working and don't mind sharing can you post your code. Im intrigued how SPI works as I have never attempted it or used it regards David |

Hi David, Here is a bit of playing around to get myself familiar with this. Hope this gives you a bit of insight on the MAX7219 with 8x8 led matrix. Haven't had much time to play but will continue to learn. 'MAX7219 routines...

@viscomjim - yes - I get this too. Typically all 64 LEDs turn on at full brightness . . . Note also: If you are driving the MAX7219's 5v from a USB-to-Serial converter then when using multiple Matrices then you run the risk of hitting the 5v supply current limit resulting in the MicroMite resetting when trying to send code from MMEdit (all LEDs on at full brightness). Point is, drive multiple LED matrix's from a capable power supply to eliminate random programming results. 
I am driving 5 of these Matrixe units in my GPS clock. Got the front panel done so its ready for a photo. Now working on a RF link for the clock. This is using a pair of Hope RFM12B's. At the Tx end, there is the GPS receiver (with active antenna), a temp sensor, a light sensor, and a humidity sensor. This is to be mounted in a position close to a window to ensure 100% GPS reliability. Then data is gathered from all these sensors and sent as a brief message on 868MHz. This allows me to have multiple clocks around the house, each with a RF receive picking up the GPS time + outside temp etc. This will then form the basis of an automated home automation system. Will also be useful for other people (and maybe Geoff) to understand how to use the Hope RF TRx's with a MicroMite (they are difficult to program due to lack of good data/examples - BUT once mastered they are fantastically reliable units).

Hi, David, I haven't had time to play with your code yet but I do have a couple of questions... 1 - The 6 column of data still has the space in it. Will this work or does the space have to be removed? 2 - Does the scrolling work across 2 or more displays spi daisy chained? 3- spi data in on uMite is not needed with these, so you have an extra pin for whatever. Also, somewhere in one of the threads, I believe the apple remote one, WW mentioned something to the effect of using individual CS for each matrix instead of the daisy chaining for speed's sake. Something to look at when time permits. Also, in the case of spi daisy chaining, I noticed in the data sheet that you can send a no op to skip over displays. More to play with. Your code looks like fun, can't wait to load it. Another uMite bit of coolness. WW - I am running the 5v from a separate supply for that exact reason. Can't wait to see your project! The data sheet also says min. 3.5 v for logic high, however it seems to work very well at 3.3v from uMite. Also your apple remote code is getting plenty of use here. I will post details soon. Thanks again. Edit, I take back the info on spi in, even though it isn't used, it will still be tied up when using the spi function. Wake up Jim!!! |

1. The space seems to be a bug when publishing the code to TBS 2. I tried the code when I got home, I only have 1 Matrix and this is the first time I've ever tried anything SPI, however spi.matrix.print "blahh", xSpeed,xDirection,xKerning e.g. spi.matrix.print "Hello World",1000,1,1 works well, I will order a couple more, the two three weeks will give me time to complete my MuP Security code for the MuP Security Plaugin The xSpeed=time displayed on 1 8x8 matrix in ms xDirection=0 ' forward 1=backard xKerning=0 or 1 ' currently not used i was thinking of changing the data format, Hex, and very extensible.allowing for more than 127 fonts (up to 4096) in the set, and support for 7-segment fonts.... watch this space my 10 year old son is busy in an Excel Spreadsheet creating characters / fonts on 8x8.... and 7-segment... other new commands he thought of spi.matrix.intensity 7 ' supports values 0 to 15 i'll probably code spi.7segment library as well in the next several weeks for everyone to use however my focus is on i2c.LED i2c.LCD and i2c.KeyPad libraries.... The biggest challenge is to get the syntax to Match Geoff's MMBasic syntax for LCD and KeyPad to avoid relearning regards David |
