[PIC] how to setup a usb host device??

[anjalimidhuna]

hi
i need directions to setup a usb host device using pic16f1454. i read the datasheet but can't get idea to code it. :roll:
i am using hi-tech c compiler

There is no USB host in pic 16f or 18f it has only device facility. pic 24f is having the host or utg facility.
you can get the sample codes from microchip application libraries.
But i don think it has support for htc.

as far as I am aware PIC16 and PIC18 devices don't support USB host (some support USB device)
you need a PIC24 or PIC32 device which supports USB host or OTG

thank you Venkadesh_M and horace1 for your help

if you are looking for a small low cost device with plenty of functionality and that supports USB host the PIC24FJ64GB002 is useful
https://www.microchip.com/wwwproducts/Devices.aspx?product=PIC24FJ64GB002

it comes in 28-Pin SPDIP package which makes it easy to built prototypes

Yes me too developing one.

Actually i'm looking for a device with 14 or less pin count

 

[Venkadesh_M]

The size of the chip is too small in QFN pack. It needs about 5 to 10 pins to configure the USB. you can leave other pins.
I think that is the small device coming with the otg facility in microchip.

from the data sheet of PIC18F4550 i got

• 1-Kbyte Dual Access RAM for USB
• On-Chip USB Transceiver with On-Chip Voltage
Regulator
• Interface for Off-Chip USB Transceiver

Can i use this chip as USB host??https://www.edaboard.com/threads/120839/
but i fount this which says no ,then what this usb transceiver means??

 

[Venkadesh_M]

USB is a bidirectional data transfer, for example if host request data then the device will send data. so it is called as transceiver.

but being a host is totally different. It will have lot of mechanism to interact different class of usb devices.
