Hi deSilva,
thanks a lot.
Well, it is CONNECTED to the FTDI chip - alas quite unbreakable - which has an USB connector. Note that this connection uses two serial 1k resistors. This is terribly important for all your experiments!!!
I have to dig the scema for the board. Are those resistors to ground?
Newer mind I will find it out myself.
Not really, the disconnection of the USB line and thus USB power does not stop the FTDI chip from working. So you can just leave it as is. The RCV line from the FTDI chip will be LOW without traffic, and - remember! - is connected through a 1k resistor. so you have a puul-down here.
I tested with one of Byvac's serial displays. I got text output working for the display when USB cable is not connected. The LCD was not connected when I uploaded the program. Anyway now when I can use the NewSerial - this is not problem any more.
It will stay open as long you do not reload a program.. So what exactly is the issue?
Issue was that I would like to see debug output from the setup routine. I was not able to figure out how to use serial monitor for that. But now when I have the BV103 connected. It is not a problem. Or I am talking nuts because I have not slept enough....
Anyway I will now try to get this BV4622 SD card system working with duemilanove.
Thanks again!
Best Regards
