Thanks for your comments. I'm so happy to hear both of you.
I know KSZ8775 is a factory out a driver-free device, no need to modify any register, everything can be done by pull-up pull-down resistor configuration.
bref working:- Microchip TCP/IP stack ICMP server (ICMP server - PIC32INTMAC - Ethernet MAC driver - MIIM driver) are put inside both PIC32s. PIC32s are interfaced with HUB in PHY MODE.
If I'm making few numbers of bord, okay agree with mbrowning.
Above schematic is a potion 4 port logger device. somebody ask me for an 8,16 or 32 port solution, can be done by PCB stack up.
My question is not about KSZ8775 HUB, he is fine.
I'm bothering about Microchip TCP/IP stack ethernet MAC driver and MIIM driver.
To go ahead these guys need replay from a PHY(Like I'm okay or I'm here).Smile:
All HUBs are available in the market, maybe only one management line(MIIM, SPI, I2C).
So as rainad said 2 approaches. Let check.
Can anyone share some code hint?
