Hi, sorry for stupid question(s).
Duemilanove has one serial port - right? This port is shared with USB - right? This port is the RX/TX pins - right?
RX/TX pins can not be connected to other serial device when sending program over the USB - right? RX/TX pins can be used when program is already stored and USB disconnected and board powered from alternative source -right?
I noted that one can use the serial terminal to communicate with the board - nice. But the terminal is always closed when program is sent. Probably because it would conflict with the transfer - right?
I was able to use NewSerial libary to connect BV103 (which is USB/Serial TTL level converter from http://www.byvac.com). With that I can even get printouts from setup routine. It was connected to pins 2 and 3. Is there way to keep arduino serial monitor open at all times?
Then the main thing. I am playing around with BV4622, which is a SD card subsystem from Byvac. It supports I2C and serial (TTL-level). It contains quite a lot functionality. So it would help if you please tell me how you think it would be used. You can get the data sheet from the Byvac's web site.I will try to implement the library for it. At least I make some instructions how to use it.
Sorry for long post.
Best Regards Kari
