Probelm regarding USB-USB connection

texas — Fri, 20 Nov 2009 08:36:16 GMT

I have developed data acquisition system using TMS320VC5509 DSP which has embedded USB slave port.

Now i want to transmit the acquired data on RS-485 network .

So there is requirement of TUSB3410 which converts USB data to RS-485 .

But problem is that how to connect both USB conncections since there isn't any USB host.

So please provide me some solution for this connection..

TUSB3410 intermittent communication

David Dobsky — Wed, 11 Nov 2009 18:43:05 GMT

Ismael,

Good day. I thought that when I ran the executable to install the updated driver, that the driver would automatically be changed. I had not looked at the device manger to see if it had actually been done. It turns out that the driver did not get updaetd. So, my comments that the situation was improved were misleading.

I did go ahead and update the driver through the device manager and had it point to the new driver files (XP32) for the TUSB. The driver did get updated with his method and now shows at 6.5 etc. However, now our VB app no longer communicates with the TUSB 3410. We have a function, 'obg.open' that opens the port and tries to communicate with the device. This is not behaving as it once did. I tried to comment out the obj.open and have it just send a command to the TUSB but this produced the same result.

I noted it looks like the driver has been updated, but when we try to download it, the file cannot come over because of some Microsoft security feature. Anyway, I'll try to download it at home and try the new driver. Any other thoguhts would be greatly appreciated.

TUSB3410 GPIO pin frequency

RMcCarthy — Fri, 30 Oct 2009 21:21:08 GMT

Some of the GPIO pins on the TUSB3410 have a frequency on them. They have noticed that the frequency changes or goes to zero after a system ESD event. They would like to monitor one of the pins to tell if an ESD event has occured. Is this some thing that can be relied on? what generates this frequency and why would it change?

architecture of analog data acquisition

joyer — Tue, 17 Nov 2009 15:45:24 GMT

Hi,

I am kind of new to the electronic hardware design. My project is to implement analog data acquisition via USB interface of the PC. The signal I have is a pulse (temporal width varies from us to ms) and the repetition rate is around 6Hz.

I looked around the website and found there are few kinds of USB IC available.

What I have in mind is: (12 bit) A/D converter + USB transceiver + PC

Is this gonna work? Or could you suggest me a better solution? Thank you very much!

USB to Analog Conversion..

Efrain Villasenor — Fri, 08 May 2009 20:04:51 GMT

Hi,

Is there a simple USB to DAC output controller, (so that the output DC voltage [0 to 5V] of the DAC is dependent on the USB)? Alternatively, a robust USB to SPI bridge?

Thanks for your time.

TUSB3410 and I2C

Peter Hull — Thu, 19 Mar 2009 14:21:26 GMT

I want to write to an EEPROM via the I2C bus and I'm following the steps in the data manual (SLLS519G). I'm finding that I need to put a delay between successive page writes, so the sequence is: send address, send 32 bytes, delay, send address, send 32 bytes ...

I'm waiting for TXE every time I set I2CDAO, as in the data manual.

If I don't delay only the first 32 bytes are written and the rest aren't.

Am I missing something or should there be a delay and if so how long (or does it depend on the EEPROM used?)

TUSB3410 intermittent communication

David Dobsky — Thu, 29 Oct 2009 14:04:10 GMT

Hello,

We are developing a product using the TUSB3410. We are using it with an EEPROM. This product communicates to a host PC during a calibration process. The software program used to communicate with the product is a VB.net app. We have found that we need to always ensure the comm port is open before a commujnication and then close it afterwards. If we simply try to leave the port open, it seems to close on its own and then a communication cannot take place. I need to know if this is a issue with the TUSB3410 or with the operating system of the PC. Also, it seems after many communications ( dozens), the communiations become intermittent and unreliable. Reliable communications are restored if we reprogram the EEPROM used with the TUSB3410. Any feedback on these matters will be greatly appreciated.

tusb6250 demo bd

Mr Dani — Tue, 20 Oct 2009 11:24:46 GMT

Hello,

i am planning to use this chip, but as i googled, found that several vendors(digikey etc) did not sell the demo bd anymore, it was said to be 'obsolete'. is this product obsolete already, or ti don't made any new demo bd, because i read the old pdf about the demo bd somewhere else, it said the bd has somekind of design mistakes.

actually, i'm gonna make an IDE/ATA/ATAPI listener using this chip. or maybe anyone could suggest me any already made pcb for the chip/already mounted to test?

please correct me if i am in wrong direction.

thank you

[Solved] TUSB2046 without EEPROM?

Michael Haslauer — Tue, 27 Oct 2009 10:58:51 GMT

Hi Guys

I am working on a School Class Project and try to build up an 1.1 USB Hub with the IC TUSB2046.

I used the reference design for a Self Powered Hub from TI (Available on Product Site of TUSB2046) without the EEPROM and design my own Schematic (Attachment).

So I tied RESET and EXTMEM to 3.3V, EEDATA to Ground and left EECLK floating.

So my qustion is, do i need the EEPROM with VID and PID or is it possible to run this IC without EEPROM?

I have already build a PCB but it doesn't work and I don't know if the error is the missing EEPROM.

greets

Michael

EDIT:

Problem Solved

Stupid Mistake, forget the transistor and pull ups from 3.3V to DP

IC also runs perfectly without EEPROM, default VID and PID is implemented.

TUSB3410

YILMAZ KIRÇİÇEK — Mon, 05 Oct 2009 14:09:36 GMT

Hi,

We have designed an USB to RS485 bridge with VCP feature. We can send data but we can not able to manage to receive.

Whenever we send any data, data is reflecting on TUSB3410 receive pin. We thing there is aproblem on DTR control.

Schematic is controlled by local TI support engineer and there was no any error.

I2C Header Utility for VCP Applicaitons is used to generate .bin file with umpe3410.i51 sent by Dan Harmon for RS485.

EEPROM Burned Utiliy is used to download firmware. Then PC driver is used supplied by TI with swrc094d code.

When we plug the device to USB port a virtual com port is appears on device manager section, say COM7.

We can send data with a test program, but we can not receive. We can communite with the same test software and test device when we used an other USB converter.

Then I new PC driver sent by local TI support engineer and told us to modify .inf file by removing umpe3410.i51 instances. But it did not work.

1. Could you please supply us;

1. A working FW and PC driver for RS485 bridge aplication

2. A PID for our product using with TI VID : 0x0451

3. Source code for firmware and PC dirver.

Best regards.

TUSB3410 being seen as Mass Storage device

Steve Thomson — Wed, 14 Oct 2009 19:19:41 GMT

I have an embedded system design where I need a TUSB3410 (or similar) device to provide communication between a Host PC and my embedded micro which does not have USB but only has a UART interface. Therefore I'm looking at using the TUSB3410. However, when connected I need the Host to see this device as a Mass Storage endpoint and not as a Serial endpoint. In other words, I need the Host to be able to communicate to the embedded system via a network interface over USB rather than via a COM port interface over USB. Is this possible with the 3410 or if not, is it possible with some other USB to Serial device from TI?

Thanks.

TUSB3210 - Regarding loading firmware from PC

Subash Bose — Tue, 18 Aug 2009 04:55:28 GMT

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4

Hi,

We are trying to use TUSB3210 EVM(REV 2) USB controller for our keyboard application.

Our goal is to download keypad firmware from host PC into 3210EVM.

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4

I am referring to section 2.5 Jumpers and Switches of Page 2-3 in Below user's guide

for TUSB3210 keyboard Evaluation board.

http://focus.ti.com/lit/ug/sllu032a/sllu032a.pdf

For this purpose we tried below 2 steps, to ensure board is functioning properly,

1. Default setting functionality:

We tried to execute the firmware which by default written in EEPROM and see

Whether the keypad works fine. But, did’nt see key press on 3210EVM displayed

On hyperterminal.

Below are setting we did,

· Jumper setting:

U3: 1-2 Speed sense always ON(Execute firmware from EEPROM).

U9: 1-2 5V power supply from USB cable.

U12: 1-2 Self powered

· Connected USB cable to pc and to 3210EVM.

· Connect UART to COM1 of PC and 3210EVM.

· Configure Hypertrm with following setting.

BPS : 115200

Databits : 8

Parity : None

Stop bits : 1

Flow Control : Hardware

When USB connected to PC and 3210EVM, we see red light on D9 LED.

2. Download keypad firmware from host PC into 3210EVM.

We downloaded the keypad firmware source code for TUSB3210 EVM from

Below website.

http://focus.ti.com/docs/toolsw/folders/print/tusb3210kbdpdk.html

Our goal is to download this firmware into 3210EVM using a loading program. It is mentioned

In the spreadsheet, that it is possible to download firmware from host PC into 3210EVM. But,

We don’t see any steps as how we can do that download?

We truly appreciate TI team to help us on this regard.

Thanks,

TUSB3210GENPDK obsolete?

Gavin Perry — Sun, 04 Oct 2009 20:42:22 GMT

I am developing an application using a generic USB interface (presumably TUSB3210) andTLC5940 LED drivers.

I can still order the TLC5940EVM-106 for $99 but apparently the required TUSB3210GENPDK interface is obsolete.

How does one use the 5940EVM these days? Is there a substitute EVM for the TUSB3210GENPDK?

Alternatively is there a faster generic USB 2.0 interface chip for driving GPIO? I would like more RAM

than is available in the 3210 without having to add too many more chips.

Thanks,

Gavin

TUSB2046B - unknown device

Christoph — Thu, 16 Jul 2009 06:57:43 GMT

Hi,

I've some trouble using a TUSB2046B on my board. I'm using the circuit shown in the datasheet of the TUSB2046B, figure 13 (self-powered hub, individual-port power management). Actually, I'm working with Windows XP SP3. After connecting the device, Windows searches for drivers and installs the "usbhub.sys" (Should be ok, in my opinion.), but then, another window pops up - "unknown device". The device manager indicates an error "code 41". I've already searched the web and there are a lot of problems using usb devices and this error code, the solution seems to be cleaning the registry, but I'm not sure.

Maybe another one already solved the problem.

Bye,

Christoph

TUSB3210 Ubuntu Apploader

Steephh — Sun, 13 Sep 2009 15:40:18 GMT

On my college they've build a custom board with the TUSB3210 on it. More information about it here: http://www.tusb3210.com

They use the driver apploader and eeprom burner from TI. It works all fine under Windows XP, but now I would like to use it under Ubuntu. Is there any driver apploader and eeprom burner for Linux? A lot of thanks in advance!

-- Edit:

I'm now using the Open Source TUSB3210 bootloader from http://sourceforge.net/projects/tusb3210/
The bootloader compiles, but when I try to upload a BIN file it fails. I've the same problem as this person:

http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg31408.html

Should this driver work or is there maybe an official TUSB3210 driver/apploader from TI?

-- Edit:

I'm sure that Ubuntu founds the TUSB3210 device. I've looked up the PID & VID with USB Viewer:

http://dl.getdropbox.com/u/1100144/USBView.png

The VID 0451 & PID 2136 should correspond with the TUSB3210 device and they are also in the TUSB3210 program. Maybe there is somebody who has this working?

-- Edit:

I found out that it fails at:

if(usb_find_busses())
die("Bus scan");

That's the reason of the error.. If I comment that lines then it says:

TUSB2316/3210 not found.
Error initializing USB

But that isn't helping me further. It looks like the USB device isn't initalizing correct, but I don't know why. :(

-- Edit: FINALLY IT WORKS :D :D :D :D

There were 2 lines in tusb.c who didn't where correct..

if(usb_find_busses())
die("Bus scan");
if(usb_find_devices())
die("Device scan");

I've changed them to:

if(!usb_find_busses())
die("Bus scan");
if(!usb_find_devices())
die("Device scan");

And now it works. :D I can upload .BIN files to my TUSB3210 devices. :D Whooohooooooooooo!

-- Edit: Installed sdcc-nf package from the apt tree and hex2bin from http://hex2bin.sourceforge.net and now I can write my programs for the TUSB3210 in Ubuntu, compile them and upload them!

msp430 and USB host for existing TUSB3410 device

Trilogis — Thu, 30 Jul 2009 19:48:10 GMT

I have an existing device A built with a TUSB3410 and an MSP430F148, speaking with a Windows PC through TI driver and virtual serial port, classical architecture. Now I want to replace the PC by a new device B based on an MSP430F248 and a USB host chip (maybe Vinculum from FTDI) to control the device A through USB. Of course I cannot modify the existing device A (already deployed 500 times).

Do you have any advice for the USB host chip ?

Would the Vinculum USB host chip handle the TUSB3410 USB slave ?

How can I emulate the UART serial port on device B ?

Tx for help

TUSB2046BVF USB Hub chip

Gert Helles — Wed, 26 Aug 2009 07:10:04 GMT

We are using the TUSB2046BVF USB Hub chip in one of our designs. During a review I noticed that the implementation wasn't quite in line with the datasheet terminal function specification. The Hub chip is equipped with a serial interface (EECLK/EEDATA) capable of reading Device ID etc, from an external EEPROM. Since we are not using this feature, the EXTMEM# pin is pulled high (deasserted).

The datasheet state that if EXTMEM# is high, the EECLK terminal is disabled and must be left floating (unconnected). In this design, however, this is not the case. We have erroneourly pulled the EECLK pin high through a 1KOhm resistor. The design is currently undergoing a revision where EECLK will be left floating.

I would, however, very much like to know, if pulling EECLK high will have any side-effects on the functionality of the TUSB2046BVF. We haven't so far observed any malfunction that we would expect to be associated with the USB Hub circuitry

TUSB2077 downstream power enable question

Andy Eadie — Tue, 25 Aug 2009 20:49:05 GMT

I would like to know exactly what the TUSB2077 checks for before enabling the downstream port power (/PWR_ON). Is it looking for enumeration with the host PC? I’m looking for a way of making the hub enable the downstream port power without the unit being plugged into a host PC.

Thanks.
