Eblock EB039 USB Block question?

[Jordy101091]

Hi all,

I have purchased the EB039 to expiriment with USB, but after looking into the datasheet of this eblock, the TX/RX LEDs are not connected.
Is there a reason for this.

Also how can I simulate the behavior of these leds as if the are connected to these TX/RX pins of the FTDI chip.

Regards Jordy

Hi Jordy,

Assuming you use large enough resistors so that you are not drawing too much current from the signal lines you can simply connect your LED and resistor between the VCC supply and the TX/RX signal. The LED will then light when the serial signal is pulled low.

Thanks for the tip Benj.
I will try that when the board has arrived.
