As you rightly suggested, I have tested the HOST and the device code saparatly and everything seems to work fine. For b Over analog switches option, such a sliding door is not required.

The schematic I have send of USB device is working fine.

Detecting Pen Drive Insertion on LPC1768

These cables are not so popular on the market, yet. For a Direct connection method, a sliding door is necessary so that users don’t plug in to both receptacles at a time. This site uses cookies to store information on your computer.

You’ll fine similar discussion on Microchip USB forum http: And USB Device circuit is at following link http: Kindly give your suggession. You may want to attach these accessories to your product set for user’s convenience. I need to have a option which will shc able to detect the connection type.

If i am detecing the insertion in interrupt mode then even after detection, there will be variations on the line while data transfer and this can cause unpredictable interrupts. The code is as follows. 1766stm transistors are enabled on the Host mode by a spare port of the MCU. How did you measure it?

Which option do you take, a direct connection, or b Connection over analog switches? Sorry, I’ve forgot to write on this modification in above post.

USB spec provides these 1766etk options for each function. I will be using the controller to interact to the PC as well as with a pendrive and i dont intend to use OTG. By continuing to use our site, you consent to our cookies.

How is it possible that i detect something like a pen drive being inserted. You may take this circuit from some KEIL board, but it is wrong one. This is for end device. Your Host circuit is almost similar to Olimex one. Both receptacles are always exposed to users.

Aha surely, It’s PNP.

Detecting Pen Drive Insertion on LPC

Please review our Privacy Policy to learn more about our collection, use and transfers of your data. For a Direct connection option, a sliding door in front of the USB receptacles is 1766st, so that just single receptacle is exposed to users at a time. 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.

Compare your schematic with Olimex’s http: It is integrated in the host controller on the LPCx chip. When you take b over analog switches, the Olimex circuits around the receptacles are applied as is. Is there any other method to detect the plug-in of USB Stick?

For bus switch of Full-speed USB, these analog switches are available. Isn’t that the obvious way to go for something that needs to be both a Host and a Device?!

It 1766stm be very helpful if you can post the relevent changes. It can be seen that Q1 that is being used is already a PNP configuration. The USB Device is enumerated fine for above code. When the door switch detects role change, firmware disable current role, and it calls stack initialization for each role, host or device. Anyway, try host and device separately, first. After detecting the USB stick, software should turn on the 1676stk trasistors before transferring data and after completion of data transfer software should turn off the both trasistors right?
