Dear guys,
I need some advice for running old program on new OS.
In my current case I have a very old (developed in 1987) Solaris (1.1) based program and It got a lot licences, have been testing over 25 years. So, instead upgrading the software clients want exact program to run on Windows and...
Dear readers,
I am confusing about how FPGA works.
I am S/W developer and I know C/C++/C# like these programming languages believe sequential process. You can easily find out when you debug step by step your code. But I dont have any idea about FPGA once after I saw the code below...
could somebody pls tell me how to convert double precision into network byte ordering. i tried
uint32_t htonl(uint32_t hostlong);
uint16_t htons(uint16_t hostshort);
uint32_t ntohl(uint32_t netlong);
uint16_t ntohs(uint16_t netshort);
functions and they worked well but no of them does double...

hi godfreyl,
im curious to know your way. could you please tell me how to implement this step by step.
if i have 8192 values in 0.12us and sampling frequency is 1MHz, how do i get signal's RMS?
1. What is a...
thank you very much thylacine1975.
that is what im looking for and im gonna try this library. it looks perfect, awesomely understandable for me :)
thanks for helping me! take care~
Hello there,
I need an advise to convert time domain info into frequency domain (i need to know signal's strength in DB or mDB).
let me explain in a detail my issue.
i got 8192 (fifo size) digital numbers in 0.012 milliseconds and those values are VPP (voltage points).
so, in order to know...
hello everyone!
im experiencing a problem with port forwarding.
I have 2 routers hold static global IPs (given by ISP). For each routers, there are local hosts behind.
Let's say, routers' ips are R1_IPAddr and R2_IPAddr where local machines R1_IPAddr_localIP1, R2_IPAddr_localIP1 etc...
I...
hi,
you can access to ur device through UART by opening the device driver.
in c it wud be like this:
int fd; // file descriptor
fd = open("/dev/YOUR_DRIVER", OPTION); //OPTION can be read only or write only, take a look at open system call
if (fd < 0)
{
// couldnt open driver, exit(0);
}...
i have a cpu and a fpga(Spartan 6) in board. im gonna write and read fpga address data through EBI in Linux kernel (2.6).
is it possible and how?
let's say im gonna write "0xFFFF" to address of 0xE0300000.
in linux, i came with some results that we can implement it by using ioremap() which...

i have been using samsung's S5PC100 cpu and it has data sheet, user guides. there is written how to load kernel and file system in NAND memory.
so, i did as shown in constructions, then kernel run out.[COLOR="Silver"]
i had same problem, what i did is reboot the system, i mean from beginning upload the kernel and file system for defined addresses.
i also searched over net and came with no results. i figured out that nand couldnt read the address of the kernel when loading.
hello guys,
im lil bit confusing on memories and ganna ask some tricks.
when we wanna write some data to a RAM address, let's say we have an "ABC" value for "0xABCD" address, we could write smth like this code:
// in C, linux kerenel
#define ADDRESS 0xABCD
char *data = "ABC";
char...
