Hello everyone,
I need to connect a usb peripheral to the Artemis P3300.The peripheral is a usb client device ,an rfid reader , from which i want to pass a short string of data to the Artemis.
My idea is to use an atmel microcontroller with usb on the go , to act as a host , read the data from the rfid reader and pass it to the Artemis using its mini usb port.
As I am quite new to this kind of engineering I would like to hear your opinion about this way of interfacing the Artemis with the microcontroller.Has anyone tried something similar? Do you think that the extUSB is suitable for a connection with a usb on the go host device?
Best regards

Hello,
does anyone know if it is possible to attach an USB<-> RS232 cable to the newer HTC Devices, since they don't have RS232 anymore (i guess)?
What I want to do is to connect some kind of blackbox to Prophet, Atom or Wizzard. But this Blackbox only has an RS232 Connector (12 Volts).
Is it possible (hardware) and is there a driver for the RS232<->USB in Windows Mobile 5 or do I need to write my own driver?
Thank you
hi
I hope u've found a solution to that probleme.
I'm really very sad that nobody has answered to this subject, is this to mean that this is a stupid question or that nobody uses PDAs for good purposes.
Well, I try to connect my PDA to a total station (a surveying machine) that has only an RS232 port.
Can u help me to find how.
Thanx
without know much about usb to rs232 convertere then i would suspect they would require usb host ablity on the pda side which non of the htc ones i know of do :S
I think Rudegar is right, a usb to RS232 adapter requires a device with USB host. Remeber I discussed this at the GPS World site a couple of years ago, when I got my Qtek 9100 (HTC Wizard).
Couldn't the problem be solved with a Bluetooth -> RS232 dongle?
For instance: http://serialio.com/products/adaptors/BlueSnapXP.php
Here is a list of manufacturers: http://www.thewirelessdirectory.com/Bluetooth-Product/Serial Port Adapters.htm
(I have no experience with these devices; some can draw power from the serial port, others have their own battery, again others have their own powersupply and need to be plugged in)

Hey guys!
I've searched and searched for something to allow me to transfer data via a serial cable from my phone to device.
Let me try to explain this.
HTC Wizard
Windows Mobile 6 (Explore 1.1)
I have style tap (palm os emulator)
Software for palm os for a stand alone fuel managment system (msefi.com)
So on my car, I use a serial cable to program and get realtime data.
Now I know they make bluetooth to serial adapters for around 70, but I was wondering if they make a mini usb to serial cable for the Mobile OS.
Anyone have any ideas?
Thanks
Chris
Well, you could theoretically get a USB to serial adapter that has a cable. Then cut the USB connector that goes to the PC off the cable and just splice the miniusb plug onto the end. I don't know about device support though I'm going to guess you would have to at least come up with a driver and the device might not support that type of functionality at all anyways.
Since the Wizard doesn't have a USB Host (aka USB OTG) the short answer is no. Even more importantly, the wizard won't power the serial adapter so the device is a dud to begin with.
The odds that the BT to RS232 connector method will work are far greater than the USB method.
Ok,
If I were to make up an appropriate USB cable.....
1) Could I get my P3600 to talk to a USB control box that controls a light display which is normally driven by a Windows PC?
2) Is there any API facility in the Windows Mobile OS that allows a programmer to send and receive USB data packets or would I have to hit the PocketPC device hardware and bypass the OS?
3) Is any of the above possible?
Thank you very much
using usb it would not be posible
usb comes in 2 types masters and slaves
htc pda's are slaves they cant init comm with usb devices
much like that you cant connect an usb harddisk with an usb webcam
trinity have usb host...
you can see in samsung -
http://www.samsung.com/global/syste...roduct/2007/7/7/324600sc32442x__schamatic.pdf
in page 6 you have usb connection,
in trinity we have usb device, if you want to have usb host you will have to change the wiring inside the trinity.
for this change you will need to replace R75 from 470K to 15K, disconnect R83 and make a short from R76 to gnd with 15K(ohm), disconnect R82 and connect Vbus to 5V
(all the numbers of the resistors are for the Evaluation Board, in the trinity it will be diffrent numbers/connections)!!!!!
this will NOT work with your pc!!!! (need more modifications but can be done)
only host option!!!
you wont able to charge your trinity!!! (need more modifications but can be done)
but you can make switch like in the PDF
and then you will have usb host.
i have done some work on the sc32442 chip and it worked with usb host
(not the trinity).
no because the cpu have something dont mean that it's map'd out in the pcb of the manufacturers
and doing a hardware mod can kill the device and will 100% surely void the warrenty
and when all the hardware changes are then don then he needs to write a usb driver for wm to support the
hardware he want to talk to if non already exist
htc seem to use an external chip to do the usb stuff which is basic
only Athena and flame support it

Click to expand...
Click to collapse
uhm ... very nice impact!
are you know the jtag pins? must be the same like your embedded board.
This is not good...
What is the first HTC device to support USB Host?
Is it that big fat thing with a detachable keyboard (can't remember the name )?
Thanks for the replies.
PS One last question....
Does anyone make an SD or miniSD port based USB controller card?
Thanks again
Is it that big fat thing with a detachable keyboard (can't remember the name )? == Athena
and yes
I'm new in this forum and my english is no the best.
I'm searching for a system to enable usb host on dual. Something have an idea?
not 100% sure about nike but the only htc phone i know off which have usb host is Athena
htc dont connect the usb host connectors of the cpu's (those cpu's which support it that is)
no cure to fix it
Rudegar beat me to it..
no usb host mean that a device is able to connect and use other usb devices such a webcams, external harddisks, mice, keyboards and the likes
yes i now what is usb host, but if is only a problem of connection to cpu we can't study how to make it?I work frequently with electronic and if somebody help me we can try to connet it. The bus of usb are only 2 wire connect it to cpu is very simple if cpu is ready to make it! Somebody have a image of this athena chip and pinout?
Hi!
Is there any (not that expensive) possibility to "teach" the HTC Touch Cruise the USB Host functionality? I want to connect a mini USB TMC Reveicer and maybe another GPS Receiver that has an MD6 Connector.
Thanks in advance
USB Host functionality (USB On The Go, or USB OTG) is hardware based, so AFAIK, there is no way of achieving that on the Polaris.
