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. Just replace the jumper blocks with analog switches.

It would be great if 1766sto can check the schematic, which is at below link and give suggetion http: When you take b over 1766stk switches, the Olimex circuits around the receptacles are applied as is. 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.

For a Direct connection method, a sliding door is necessary so that users don’t plug in to both receptacles at a time. It’s the standard way for the host to detect device connection.

Isn’t that the obvious way to go for something that needs to be both a Host and a Device?! To connect two receptacles to this ports, there are two ways. For Host mode, you don’t need any extra circuit for device plug-in detection. Which option do you take, a direct connection, or b Connection over analog switches? And are there any changes that are supposed to be made while 11766stk controller is used a end device.

In this case, your 1766dtk should have a mechanical shutter in front of the receptacles, so that users should plug to just one receptacle at a time.

Kindly let me know if what i am trying is right. But the emitter and the collector are swapped on the schematic. Anyway, try host and device separately, first. It can be seen that Q1 that is being used is already a PNP configuration. As you rightly suggested, I have tested the HOST and the device code saparatly and everything seems to work fine.

And USB Device circuit is at following link http: Both receptacles are always 1766sfk to users.

The USB Device is enumerated fine for above code. It would be very helpful if you can post the relevent changes. 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.

Schh surely, It’s PNP. 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?

This is for end device. How did you measure it? When the door switch detects role change, firmware disable current role, and it calls stack initialization for each role, host or device. These cables are not so popular on the market, yet.

For bus switch of Full-speed USB, these analog switches are available. Compare your schematic with Olimex’s http: These transistors are enabled on the Host mode by a spare port of the MCU. How is it possible that i detect something like a pen drive being inserted.

Detecting Pen Drive Insertion on LPC

I need to have a option which will be able to detect the connection type. USB spec provides these receptacle options for each function. It is integrated in the host controller on the LPCx chip.

I don’t know why it works. The schematic I have send of USB device is working fine.
