TUSB3410: Config the USB-Serial Chip (use GPIO for Rx/Tx LED control, enable RTS)

HI BR,

This function is enabled through the FW that is loaded at start-up. I believe control flow is enabled when FW is loaded but there is no GPIO setup for your desired function. 

Hi Malik,

thanks for your answer.

I have done some measurements and RTS is working when I manually switch it on or off (for example in Docklight).

The problem now is that when I use the "RTS high while sending" setting in Docklight, the RTS line is always low.

Here I think I have to use the RS485 Data Mode.

Where can I get the firmware for RS485 Data Mode?

I have found a evaluation board with TUSB3410 where 2 LED were connected to P3.0 (RXD) and P3.1 (TXD) (SLLU041).

So I think it is possible. But do I have to write my own firmware or is there anywhere a setting to configurate the GPIO's.

Hi,

could you tell me whats the difference between these two software files?

Hi,

You can find the differences between the two modes in the datasheet under 5.3.4 Serial Port Data Modes. 

Hi,

In the zip file you provided me are two firmware files. umpe3410.a51 and umpf3410.a51. The question was, what the difference between these to files is?

But I found out, that umpe is for eeprom use and umpf for usb, correct?

These firmware files are 14kB big. I have a mounted 64kB eeprom on my TUSB3410, but I'm not able to burn this firmware onto the eeprom. eeprom burner says the eeprom is not big enough. Do you know why this 64kB eeprom is to small for a 14kB firmware?

Hi,

Sorry about that. Correct umpe is for EEPROM and umpf is for driver upload to TUSB3410. The flashburner also write USB descriptors to the EEPROM. Have you selected 64 kBit at the top of the window?

Hi,

Yes, I have selected the 64Kbit eeprom on top.

But when I press the burn button I get this error message.

65536 bits (64 Kbit) are 8192 bytes (8 KB).

Can you try the "512Kbit & up" option?

Thanks Clemens, you are right. The eeprom is 64 Kbit and the firmware 14Kbyte (112Kbit).

I have another question. In the old version of the product the TUSB3210 was used. Now we want to use the TUSB3410. Do you know if the driver for TUSB3210 is also working for TUSB3410?

VCP driver for TUSB3410 can be found at the link below.

We have already downloaded and tested the driver, thats ok.

The question is, if the TUSB3410 is also running with TUSB3210 driver?

When someone has installed the TUSB3210 driver on his PC, is he able to plug in the TUSB3410 and it is working without installing a new driver? The same PID and VID will be programmed onto the eeprom on the new device.
