    i'm french student so i think that my english would clear :) :p

    so i'm riting right now because i've problem
    i'm working on a project i have to do a CLOCK on a Matrix LED

    so to do hour second minutes ..... no problem i use the DCF77 signal
    the hard part is to control the Matrix led i use a "3216 Bicolor LED 5mm Dot Matrix Display Info Board" from sure electronic


    in this they a microcontroller HT1632 led driver

    so i think that i understand how to initialize the HT1632 in VHDL but i don't understand how to initialize the 4 components in the DE-DP14211, and after that how to chose one of the componet

    i must use a piso code but i don't how to do this code help me please

    and i don't understand how to write something on the led matrix in VHDL because it's adress and how to say that we must to turn on 1 led ??

    so if someone have solution for me it's cool

    thank you very much

    I am french also and I must also drive this same matrix by FPGA. Maybe did you find the solution ?
    Best regards.

    I succeeded in managing the matrix with a FPGA. Every thing is in the documentation. You can also read the documentation of HT1632C and 74HC164 for the chip selection.
