Arduino and 6.5" 7-Segment LEDs

I have the sparkfun 6.5" LCD and the Master and Slave controls made by Ocean Controls.

They are set to Serial mode, and I can send serial commands to make them display.

I have a timer program running using MSTimer2.h and it outputs to a LCD panel using lcd.print and to the 7-seg's using Serial.print.

The counting portion works correctly but there is a flicker on the LED panel.

Any ideas on how to lose the led flicker

I assume you mean the flicker as the digits change. This is caused by you not writing the software correctly and have a transitory state transferred to the outputs. However you need to post the software (using the # icon) and a schematic to tell exactly what you are doing wrong.
