Looking for simple USB interface

[ZeRoN]

Dear all,
I'm looking for simple USB device design.
(slow speed) using an MPU, such as x51.
don't need USB interface chip.

Any idea? :?:

Thanks HMX, look good!, but I can't read Czech.
Hope english version will be available very soon.

It is easier to use an interface chip, usb is not easy, it is a high speed differential analogue interface with clock recovery and bit stuffing going on. You need that serial interface engine! Save a lot of headache.

I am using Philips PDIUSBD11 interface chip, application notes, schematic and sample app can be found on beyond logic website.
Works ok.

You have to consider of device driver.

It is very important.

Dear Zeron,
If U need a simple device acting as USB slave device U can use some RS232 to USB bridge... U'll found many cheap component... I recommand you FTDI chips (works cool and is simple to interface with any kind of controller...):

Maybe you can look microchip, they have certain MCU embedded with USB interface. go to this website www.microchip.com

hai.

i think www.ftdichip.com is better for serial to usb control.
its easy for microcontroller application aslo

bye
