7 segment question

--- Quote Start ---

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'll try to do it, it sounds good.

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..)

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.

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.

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.
