i am trying to interface a USB mass storage device, i don't need much functionality just need to read a few sectors from the device and place it in RAM, and probably display it on monitor.
and where can i get more information on NIOS, thx again
sl811sh
i posted this earlier too but this is the correct place to do it so i am posting it again.

thank you for your reply.
i am not familiar/comfortable with any soft core processers, would you recommend a easy-to-learn-n-use 8/16 bit processor for me.
if it can be done, i would prefer to do it without a processor.
thx
i am using Xilinx Webpack 7.1, ModelSim 5.8b simulator and XSA-50 (@ 50 Mhz) board. the synthesizer is XST (i think).
what i intend to do is this, i want to take input from the pushbutton on the board, debounce it and when it is successfully debounced, wait for some delay and then toggle a bit...
i want to interface cypress's sl811sh to a xsa-50 fpga board so that the combination can act as a usb host.
sl811sh can be used as a low/full speed host controller with one usb port, with 8 bit i/o which can interface to a microcontroller.
i need just need basic enumaration and handle bulk...
using sl811sh IN packets
i am trying to use cypress's sl811sh as a host, i am unable to understand a few things about this chip
when using sl811sh as host,
does the host automatically generate the ACK handshake after correctly receiving the data packet from targeted device?
and do we need to...
plot unit step signal in matlab
i don't know of any built in function for unit step. but try this
%ustep.m
% ustep(0,5) = [0 0 0 0 0 1 1 1 1 1]
% ustep(2,5) = [0 0 0 0 0 0 0 1 1 1]
% ustep(-2,5)= [0 0 0 1 1 1 1 1 1 1]
function unit=ustep(delay, half_length)
zz=half_length+delay...
from my point of view negative frequency is a concept associated with exponential fourier transform/series
to begin with lets talk about the trignometric fourier transform, it says that almost every finite signal can be expressed as a sum of sinusoids with varying frequency from 0 to +∞, no...
Re: implement USB host, specifically for a mass storage devi
i am sorry but i am quite new to usb and i dont know what a OHS9001 usb host is . would you kindly clarify
please suggest a possible implementation of a USB host using a XSA-50 board. i would like to know
which host controller chips are easy to use?
or can i use a USB tranceiver and write all the SIE myself, how difficult would that be?
or are there other alternatives?
This implemenatation only...
