Hello,
I am using LPC2478FBD208,551 in my project. Here I am going to use 2 USB type A and LCD Interface.
For Both the USB Type A i am using USB Over Current Sense IC which send OCE Signal to LPC2478FBD208,551 for both the USB.
Now the Pin#88 is shared between LCDVD14 and USB_OVRCR1.
So my question is How to sense the OVRCR1 pin?
Can I use any GPIO Pin for the same?
Please suggest the Guidance.
Regards,
Alpesh.
Hi Alpesh,
You might add external over-current protection circuitry on USB ports. You could also take a look to the following link:
lpc2000 | LPC2478 with two USB host and LCD?
Hope this will be useful for you.
Best regards!

Hello CarlosCasillas,
Thanks for the Input.
But here little bit confusion and not received my answer from the link suggested by you. So need further help from your side. I have Explained the Query as below. Please go through and provide your suggestion.
"I am using LPC2478FBD208,551 in my Product and now I am going to revise the Design. In previously I am using LCD Interface and 1 USB Host Interface and this design work very well. Now in new revision I want to add 1 more USB Host means 1 LCD+ 2 USB Host. The problem is that there are two pins which are shared between USB and LCD interface, Pin#88 (LCDVD[21]/USB_OVRCR1/) and Pin#74 (LCDVD[12]/USB_PWRD1/).
How can I use the 2 USB Host and 1 LCD at same time?"
So Please Guide to me.
Thanks in advance.

Alpesh.
