Blinking the digit

[shoaibkazemi]

my digits are blinking how can i fix it to show fix digits

Blinking the digits is not on by default. Can you share your sketch, so I can have a look.

I assume you already solved you problem? Will close this issue for now and reopen if required.

I just had a look, you are using the second calling signature as can be seen in SevenSegmentExtended.h and you are setting the second argument blink to true.

/* Prints given time to the display
@param [in] hour        hours or minutes
@param [in] min         minutes or seconds
*/
void    printTime(uint8_t hour, uint8_t min, bool blink = false);
/* Prints given time to the display
@param [in] t           time given as an int, e.g. 1643 prints 16:43
*/
void printTime(uint16_t t, bool blink);

So this is all expected behavior. But the documentation in the README is not clear on these two calling signatures. I will update the documentation and set the second calling signature to not blink by default. Until then you should use:

printTime(someNumber, false);
// or
printTime(hour, min, false);

Hope this helps.

Just updated the documentation, will close this issue now.
