Re: New beta release "DMD2" Library

Can confirm from the built -in sample, if you use this font: const uint8_t *FONT = Arial14; The display simply keeps scrolling the text continuously. With this font: const uint8_t *FONT = SystemFont5x7; It fills the display and then stops... Will investigate the code a bit more in depth over the wee...

Re: New beta release "DMD2" Library

Fairly sure it was the SAMPLES -> DMD2 -> ScrollingAlphabet

Will try it in the morning to confirm this.

Re: New beta release "DMD2" Library

Curious to know why the size of font changes how text is displayed? If you choose a large font - once it reaches the edge of the display the first characters 'scoll' off and the new characters come on the end. With the small font that spreads across two lines - it basically fills both lines and then...

Re: Arduino MEGA 2560

Gotcha - thanks for that - have been testing VS2012 as shown here: http://www.megunolink.com/building-ardu ... al-studio/

Will change the hardware type and go from there.

Re: Arduino MEGA 2560

I get an error when compiling: Error 8 error : error: 'PORTH' was not declared in this scope Something to do with these #defines: #define LIGHT_DMD_ROW_01_05_09_13() { PORTH &= 0xE7; } // { digitalWrite( PIN_DMD_B, LOW ); digitalWrite( PIN_DMD_A, LOW ); } #define LIGHT_DMD_ROW_02_06_10_14() { PORTH ...

Re: Arduino MEGA 2560

Nice work - will put it to the test on my Mega2560 clones tonight and report back the results.

Re: DMD PWM

The trouble is that a number of things changed with v1.0 - for example wprogram.h became arduino.h If someone could point out where the other changes are then this library could be made useful again. e.g. these snippets of code are 'broken' as well: CDmdPWM::~CDmdPWM() { if(m_PWMValues!=0){ free( m_...

Re: curious about capabilities

I saw that and have had a play - just curious to know about the limitations of the hardware and how much is imposed by the display itself and how much comes from running it off an arduino as opposed to a RPi or other faster platform?

curious about capabilities

Having seen this: http://www.kickstarter.com/projects/erogear/fos-a-truly-wearable-bluetooth-led-display-system I wondered if this DMD could meet these specifications: "With 64K shades of light for each and every pixel, gradients, 3D objects and other artwork are at your command." Is it a limitation...
