use sdram controller from xess
there're lots of files abt SDRAM controller on the internet,
i'v seen some of them, none of them can be used in my project.
in my project,
CPLD functions:
1. receive data(8-bit parallel) from 89c52,
2. write and read sdram(1Mx4Banksx16bits),
the address and...
A question about P*otel DXP 2004...
i installed 2004,but i don't like it.
it's complicated.and i can't bear with the startup procedure.
and ,i think,yes, u need the nanoboard
unrecognized device or socket is empty pof datei
have u installed the driver?
if u use WIN2k or WINXP,u must install the driver .
i use EPM7128SLC84-15,too.
buffer
u mean,u just want to make sure which package of FPGA u should choose, don't u?
or to design a protect ciucuit?
if package of FPGA, i suggest PLCC, well, u could use a chip carrie socket for PLCC.
in my design ,i use CPLD,EPM7128SLC84, for removing it expediently,i bought a PLCC...
or can not have such operands in this context
u want to generate the timing of VGA,right?
i've written one that is similar to urs,according to ITU- RBT 601,and i use quartusii .
i couldn't understand ur code.
u could write me ,and we can discuss it
if u need 10mhz crystal,
i don't think the resistor is necessary.
and if th dependability of ur system is required very strict,
i suggest Voltage Controlled Crystal Oscillator (VCO, 4 pins).
Re: using time delay
after is useless for synthesizing.
i've seen an article abt how to delay.
the high frequency clk will be used to drive a shift register,
the input is the signal u want to delay,
configurating the register according to the delay time of the signal.
the output is the delay...
