HOW TO INTERFACE PMOD NIC 100 WITH NEXYS 3 board

Question

Hii..

 

I am a beginner and presently I am working on NEXYS 3 FPGA board, I am trying to communicate NEXYS 3 with my computer using PMOD NIC 100.

 

My doubt is how and by using which Protocol can I interface my PMOD NIC 100..??

 

can it be interfaced by RS232 since I have to transmit temperature data only (I am using PMOD TMP2 for that)

 

Is it a proper way to communicate it..??..Or should I use any other protocol..??

 

Kindly Help...

You can talk with the PMOD over SPI - Wikipedia has an overview at http://en.wikipedia.org/wiki/Serial_Peripheral_Interface_Bus

 

You can find the hardware detail in the reference manual at https://www.digilentinc.com/Data/Products/PMOD-NIC100/PmodNIC100_rm_RevA.pdf

 

The PMOD use's Microchip's stand alone Ethernet controller - ENC424J600 - you can find the full datasheet for the chip at http://ww1.microchip.com/downloads/en/DeviceDoc/39935b.pdf.

 

To use the chip there are thirty or so registers, and quite a few may need to be set appropriately before Ethernet frames can be sent. It might pay to experiment with it for a while in a more software-friendly environment - perhaps hook it up to a micro-controller and experiment with it for a while....

I have to agree with Hamster here, I think it is going to be tricky to learn how to use the PmodNIC100 on an FPGA board if you are not using a microblaze core. Hook it up to a chipkit or arduino and figure out how to send/receive simple packets, then you will better understand what your HDL will need to look like.
