Hey Mike, I would like to see your report or related material for guidance. I'm currently making a similar project, and I'm struggling with the audio effects. Thanks
Hey Mike, that's some great work. I'm an EE major too, and I just recently bought my first FPGA dev kit, although mine is from Xilinx (Spartan-6). I have also been taking a look at the report your submitted for this, and it has been a very interesting read.
Why do these demos keep showing twiddlers, constantly turning the effects so that you cannot hear what they are like in a given setting?
You could use a comparator. You can set the analog voltage "trip point" where the bit will toggle..It will give you a one or a zero.. You can even make your own successive-approximation ADC using a DAC and a sample-and-hold circuit.. ADC's are cheap and easy to program. Just get one that uses the SPI port.
Hi Mike, I'm interested in your project but unfortunately your site is under maintenance. How can I know more about it? Thanks in advance
Thanks! i've heard of it but not used any of the Xilink stuff. Is it just the equivalent to NIOS II from Altera? I only used Altera because it was readily available to be honest. I'll be uploading my project report soon if your interested. What kind of stuff are you looking to do?
Have you seen the discuss/comments section on the webpage for this ? Click the link in this video description and ask away. I'm sure i can help
great phaser
Thats great, upload a video of you project when its done. What kind of stuff will you be doing? thanks for your interest
cool
Hi, how many logic elements did you use in VHDL?, do you think it is posible to do it with an CPLD?
How can I know more about it? Thanks in advance
Just a question since I don't know much about FPGAs, since they are re-programmable logic gates, is it possible for FPGAs to process analogue signals without having a ADC?
No, unless they have a built in ADC which most FPGAs do not have.
Looking to purchase this board for my graduate project and have a question regarding the codec. please email me. Thanks
Hi Mike I am forma Mexico and I want to see if You can help me with your schematic and software i am learning Andes i lo e tour video si ver y nice
thank
Hi, i am quite busy but may be able to help. Have you been on my website? jugglingpirate[dot]net
I added a discussion feature for questions like this so we can keep it all open (rather than email) so others can learn as well. You can of course still contact me directly using the contact form on my site
