I am a new Altera FPGA learn. My English is very poor.I have learned FPGA for 3 weeks.I think it is a littlte difficult.Quartus ii ,Nios ii,Modelsim a lot of sfotware i have to learn.This my time to post a thread in this forum.I am very happy.:)
--- Quote Start --- hello nice to meet you. welcome to the world of FPGA. --- Quote End --- nice to meet you too.i am a graduate student for a Master's degree。i think FPGA is very useful,so i begin to study it by myself.It is real difficult.:) how long have you study the FPGA?
--- Quote Start --- hii all,,,,, nice to see the fpga guys. I hope this forum will be helpful. --- Quote End --- nice to meet you.i think this forum is very helpful.i think you are very good at FPGA.i think you are a good friend for me to learn FPGA.nice to meet you.
hello wi7.I have been working as an FPGA engineer since 2004. working really hard. my first design was released in 2005. but,I am still studying it. how long you will study is depends on your environment. but I am sure you will study forever as long as you work on FPGAs. good luck!
hii akira...could you please help me with SD card interface to write data on it. I saw the demo program to capture the image on run time. (VEEK- MT). I want to store the images in SD card. Could you please suggest.??
well. that is tough Question.because, it is depends on your environment. first of all. SD card is basically connected with SPI wires. SPI wires to where is you Qsys. if your Qsys has HPS(ARM CPU) and OS runs on the CPU. device driver on the OS manages SPI, you can just mount SD card. if your Qsys just has NiosII. you have to have some IP core ( translating Fat file system) or run OS on NiosII. you can even access to SD card directory. I can not explain how to do that here. you need to read specification. that is tough and you can not read SD card by PC unless you write Fat file system by yourself.
I have formatted the SD card in FAT file format. I have a demo project of VEEK MT in which the camera captures the image on run time. So there is SD ram interface and the protocol used is I2c for cc capture. Now I want to the captured image to be stored in the SD card. In the RTL netlist the connection is like the O/P coming out from sram. So IF I want to introduce SD card then Do I need to interface the SD card with sram with spi protocol. So what ever the the data store in sram on run time it will store in SD card.Please suggest am I on the right track??
