PIC to ethernet - is it possible?
Started by zalzon 9 years ago
Hi,
My research into my embedded webserver project is going in
circles. I need to find some way to connect the PIC to an ethernet
controller before I attempt to write a working TCP/IP stack.
I have a 32bit 5volt PCI ethernet card. Is it possible to connect the
PIC chip to just a few o...
Non-PCI gigabit Ethernet controller
Started by DigitalSignal 8 years ago
Hello there,
I wonder whether somebody provide non-PCI gigabit Ethernet controller.
I mean a Ethernet transceiver with PHY and MAC that can interface a
DSP, or a microcontroller to Ethernet communication.
It seems most gigabit Ethernet controller are communicating to PCI bus.
