DK3200 applications

Another try

Removed R12 (4k7 on the rev0.1 board) and replaced it by

an adjustable

Result: success with part of enumeration at a value 7k2, but

not stable

One time, the enumeration-process completed. That was, before

I removed the LM

Don't understand why the DK3200 ist detected as a full speed device,

thought this is defined as low-speed-device by the pull-up-resistor

at line USB- ...

Of course Windows-Task msgsvr32 always hangs up.

So we had ONE complete enumeration at last.

Hi,

I have tested the code given above, by prancergokaka.

This works on a DK3200 V0.1 board, with no modifications.

I too have problems with the newer code, from www.psdst.com.

I will give more information as I find it.

Hi,

Just an update, although my kit is up to date, it has old silicon on it.

Date code 0223

The November 2002 datasheet has a note on the last page discussing USB reset.

Devices dated after 0242 have the option to disable the USB reset action to the mcu/psd hardware.

This also means that I can not use PWM4 until it's changed.

This may be part of the USB problem we are seeing.

I will repace the device and give an update on the result.

Hi,

The errata released by ST for the DK3200 board fixes the problem.

(using old silicon too ! )

Simply change PC2 from Vstby to another function

Errata attached.

Bingo!

My rev-0.1-board has 4.75k for R33.

I switched vstby off at PC2 and there we are -

Display is fine now and USB works!

I will replace R33 as next.

So I am on the road again with USB applications.

Thank you!

Hi guys

Were the problems with the USB ever resolved?

Please let me know.

I am about to investergate the eval board.

Thanks
