Hi,
I'm building a very low cost PC Oscilloscope. I have lots of spare PC-100 SDRAM chips and would like to use them instead of buying FIFO. I cannot use the computers memory via PCI because the PCI card cannot guarantee memory access all the time. Therefore I would like to use SDRAM in my circuit board.
I understand it's complex to use SDRAMS. I have an idea that could simplify the job. Instead of having my circuit do all the initializations, etc. to the SDRAM, why not do it through software on the PC? Is this a good idea? I have no idea since I am not familiar with SDRAM. The software could have access to the pins of the SDRAM.
Does anyone have any suggestions, web sites, information? I have no idea what signals I would need to send to the SDRAM. Also, once the SDRAM is setup / initialized, how can my circuit save & read data to and from the SDRAM?
Many thanks!
