Mohamed,
If you are using code b decoding you must set bit 7 in the register data for
any digit you want the dp on .
Hope this helps.

Hello,
I know how to display number such as 25500 using MAX7219 and keypad with
BS2,but how can I display it with decimal point such as 25.500 since the
AppKit code for MAX7219 start to display digits to the right with leading
zero blanking ?.Any idea would be appreciated.
Thank You
Mohamed Refky

I know that,as for 25.500 DP is for digit no.4 but when pressing 2 it will
start from the right hand side of the display and the DP may stay there on
the left all the time.
