Can anyone upload (or link to free download) for the brother MFC-215C service manual please? I am having "unable to print" error and I cannot fix it with simple things.
Thankyou all

floorplanning xilinx ise
1. Does anyone know of tutorials that show how to use ISE to floorplan the modules in an FPGA design?
2. Once I have floorplanned a design is it possible to find out the input-to-output timing of a single module? The way I have been doing this is to make a new project...
Hi,
Don't forget to look at the board list at fpga-faq.com!
Also ask your local distributors what they would recommend for your application.
We recently bought a large FPGA system for system prototyping. Some of the systems we considered that circuit_seller didn't mention were Annapolis...
Hi,
I would like to buy a development board for home hobby use. I am interested in SoC, DSP and SDR. Some of the old-computer-system-on-chip projects on the internet (e.g. Atari ST, Amiga 500) also look interesting. I might have to try something similar :-)
I am considering between the...
I can't see the schematic on that web page (it seems to be broken), but here is another auto-power on circuit. It has a pretty thorough description of how it works as well as schematics.

I hope it is what you are after.
xilinx ise vs edk
Xilinx ISE (Integrated Software Environment) is a package that contains the suite of programs needed for the entire FPGA development flow. Includes design entry, synthesis, P&R, device programming. Also simulation via modelsim, as an option.
Xilinx EDK (Embedded Development...
Re: OFDM, my misconception?
Ah. I don't have any experience with that sort of channel. I guess spikes caused by changing loads may cause problems? Error correction for that type of channel may be interesting to research.
Yes. OFDM can be layered on top of QAM, BPSK, etc. The "whole...
Re: OFDM, my misconception?
It is completely up to your implementation. If you choose to transmit n symbols on n channels (i.e. no redundancy) then you will still lose data if one of the channels fades... or you will correct the data with some error correction scheme. However, you will lose...
Whether you can use fixed- or floating- point depends on your application. You have to consider the dynamic range (i.e. the difference between the largest and smallest numbers that can occur in your computation) and noise floor that your application requires. Both of these will probably be...
Re: the alogrithm to solve eigenvalues of matrix
tarkyss,
There are some methods mentioned on Wikipedia. I would select whichever of these is least complex, but still efficient for the size of the matrix you are working with. Once the algorithm is selected, you need to map into hardware. I...
hi-tech ou ccs
I've never used the hi-tech compiler, but I would strongly advise against CCS.
Last year my uni purchased CCS to use to teach some robotics practicals. That it doesn't conform to ANSI C was a minor issue (in comparison). The main problem was that the software is buggy and...
ctype vcs
I have seen the same error messages before with Scirocco (2003.3) and have managed to fix it. I'll warn you now that it is not exactly a clean fix and would probably be frowned upon in a production environment even if it works for you. I assume the same fix might work for VCS too...
