I need 1766skt have a option which will be able to detect the connection type. Is there any other method to detect the plug-in of USB Stick?

After detecting the USB stick, software should turn on the both trasistors before transferring data and after completion of data transfer software should turn off the both trasistors right?

Just replace the jumper blocks with analog switches. For bus switch of Full-speed USB, these analog switches are available. And USB Device circuit is at following link http: This site uses cookies to store information on your computer. Sorry, I’ve forgot to write on this modification in above lp.

To connect two receptacles to this ports, there are two ways. 166stk option do you take, a direct connection, or b Connection over analog switches? Compare your schematic with Olimex’s http: Isn’t that the obvious way to go for something that needs to be both a Host and a Device?! For a Direct connection option, a sliding door in front of the USB receptacles is necessary, so that just single receptacle is exposed to users at a time.

It would be great if you can check the schematic, which is at below link and give suggetion http: Kindly give your suggession.

For b Over analog switches option, such a sliding door is not required. Products Download Events Support Videos. It would be very helpful if you can post the relevent changes. USB spec provides these receptacle options for each function. When you take b over analog switches, the Olimex circuits around the receptacles are applied as is.

Anyway, try host and device separately, first. When the door switch detects role change, firmware disable current role, and it calls stack initialization for each role, host or device. This is for end device. Although i am not quite sure if i can use the transistor part on top of the circuit to detect the device pen drive plug in.

You may want to attach loc accessories to your product set for user’s lp. For Host mode, you don’t need any extra circuit for device plug-in detection.

These transistors are enabled on the Host mode by a spare port of the MCU. It is integrated in the host controller on the LPCx chip.

You’ll fine similar discussion on Microchip USB forum http: Aha surely, It’s PNP. It’s the standard way for the host to detect device connection. These cables are not so popular on the market, yet.

Detecting Pen Drive Insertion on LPC1768

As you rightly suggested, I have tested the HOST 7166stk the device code saparatly and everything seems to work fine. Both receptacles are always exposed to users. How is it possible that i detect something like a pen drive being inserted. Please review our Privacy Policy to learn more about our collection, use and transfers of your data.

Maybe, the pins on your footprint of the layout is swapped? Your Host circuit is almost similar to Olimex one.

The USB Device is enumerated fine for above code. I will be using the controller to interact to the PC as well as with a pendrive and i dont intend to use OTG. But the emitter and the collector are swapped on the schematic. For a Direct connection method, a sliding door is necessary so that users don’t plug in to both receptacles at a time.
