dear edaboard fren..
i want to build my own pic usb development board,
i just want to make it so simple..
just 4 led, 4 input button, 1 potentiometer,
and 1 16x2 lcd..
what pic would u like to recommend other than 16f84550?
or someone who have the pcb layout for similar pic usb board can share with me?

There are many USB enabled chips from microchip other than 18f4550. Better go their website and search. But some of them are not available in DIP, thats not a problem if you can etch good PCBs.
If your interested to study about USB Host then go for a PIC24F series controller with USB HOST, some of the USB OTG enabled PIC24F controllers are available in DIP.

Try to draw PCB by your self.

Good Luck.
 

yeah..i already go to microchip site..
im just asking for advice and mybe someone have done it before,
so i dont need to waste my time to design the layout..hehe..
so lazy guy..anyway tanx for you suggestion.. :)
about USB OTG, what does OTG? what the function of it?
 

We have recently built two PCBs using the PIC24FJ64GB002
PIC24FJ64GB002

one as a USB end device (slave to connect to a PC) the other as a USB host (for a USB flash drive)
the advantage of the PIC24FJ64GB002 is it is available in 28 SPDIP and has Peripheral Pin Select (you can select at run time what Peripherals attach to which pins) so making and building the PCB is easy (we use a router for making PCBs and can make them in a couple of hours)

software to drive the USB together with example programs is available from the Microchip USB page

OTG is USB on the go - means the USB interface can act as a slave or host depending on what is attached to it

you need to work out how many IO pins you need which will effect the choice of chip - to reduced pin count you could use an LCD in 4 bit mode which reduces its pin count to 6 (4 data + enable + RS)

once again..tanx for usefull info..
usb host and slave in single chip..interesting..
