Arduino : 4-digit shield now scrolling

This is what the updated library “printstr” will look like.  I have to do some more work on this library later this weekend.

Please see the downloads page for the latest version of the 4-digit shield driver library.  Currently V2

Arduino : MAX6953 driver for 4-digit shield.

I’ve uploaded a first version of the ShieldStudio Arduino library.  This library allows the usr to use the 4-digit shield without in depth knowledge about the MAX6953 display driver.

There are lots more to do in the code,  but for now it should be good for inexperienced users.

This version of the library supports:

  • setBrightness(char bright);    // set display brightness, 00 – FF
  • int version(void);                       //get the library version
  • void Test(bool onoff);              //turn on/off all LEDs in MAX6953 test mode
  • void ShutDown();                     //put the shield in low power standby mode
  • void WakeUp();                        //Wake up from standby
  • void WriteDigit(char character,char segment,char plane);  //Write one character to segments 1 to 4 plane can be 0 or 1
  • void Write4(char* str,char plane);                                               //Write a 4 characte string to plane 0 or 1
  • void BlinkOff();                                                                                 // Blink will switch display to plane 0 and turn blinking off
  • void Blink();                                                                                       //Switch between plane 0 and 1 automatically
  • void BlinkFast();
