This attribute makes your code more portable and versatile, so it should be used. The first is the signal that you want to convert, the second is the length of the resulting vector. First you need to think about the range of values stored in your integer. Can your integer be positive and negative? Both of these conversion functions require two input parameters. Is it signed data or is it unsigned data? Learn more. Asked 11 years, 3 months ago. Active 1 year, 1 month ago. Viewed k times.

I've written more on this subject on my blog Fundamentally, I'd change your 7seg converter to take in an integer or actually a natural , given that it's only going to deal with positive numbers - the conversion is then a simple array lookup.

I'm going to pass on your info to him - the textbook we used didn't delve into VHDL 'morality' questions. There is no guarantee of cross-vendor compatibility with the non-standard libs, though it typically works fine. It is good form to move on to the standard now though.

Sorry about that. I don't know if it's clear. This is really getting nowhere. Actually, it uses serial port's concept to do communication. ZigaM Junior Member level 2. I have similar problem. For example.. Thanks a lot. TrickyDicky Advanced Member level 5. There is no conversion at all. A std logic vector is just a collection of bits.
Its just a collection of bits. Is this data not already ascii? I will refraze my question. You're going to need a divider to work out all of the different base 10 values you need.
I find the decimal on this then I work it out in my book. I am a 11 year old I am in grade 7 standard 5. Thanks for what all you had developed it is helping to prepare fro my computer exam very ell tomorrow. Facebook Twitter. Binary Value Convert. Step 1 : Write down 2 and determine the positions, namely the powers of 2 that the digit belongs to.
Step 2 : Represent the number in terms of its positions.
