7 segment question

--- Quote Start ---

im doing a project on vhdl and using cyclone III and part of it is to use the 7 segment display.

i know how to do it the simple way but

is there any component that can be used as a decoder connected to the ssd?

Here's one for you.

thanks dude

but what you have is the way i know, where u do the decoding urself.

what i mean is a component that when the input is "0000" gives u the output "1000000" and so on.

Hi there,

do you think of a hardware component like the 4511 CMOS IC or the 74141?

(so called BCD to 7-segment decoder)

The benefit could be, that the I/F between the FPGA and the 7-segment reduces to 4Bits rather 7Bits and the current for the 7-Segment is by the driver IC rather being an I/O current of the FPGA. (But these are all benefits that came to my mind..)

If you have a 4-bit register, or say a Qsys system with a PIO component, and you connect those 4-bits to the hex_display input, and the hex_display output to the 7-segment display, then when you write 0, 1, 2, 3, .. E, F, the display shows the corresponding hex values.

thanks man, i know the 4511 but im looking for a component within the FPGA like lpm or ff that does the same as 4511.
