Is there a way for me to program a chip to communicate, in a serial fashion, through the usb port to a program waiting on my machine? I want to be able to receive data, and possibly even program a flash or eeprom. - Jeffrey Drake

Sure, use a chip with a USART and then use a FTDI or similar USB adaptor chip instead of a RS232 chip. >I want to be able to receive data, and possibly even program a flash >or eeprom. Put a bootloader into your chip and you can program your chip. So now back to the topic, what has this all to do with the Dragon? (I guess you can use it to program the bootloader) Regards John Samperi ******************************************************** Ampertronics Pty.

He has only a Dragon, and he wants to be able to program a free-standing EEPROM chip connected to the processor plugged into the ZIF socket on his modified Dragon. He doesn't have an EEPROM programmer. > _,_._,___ He also doesn't have a serial or a parallel port on his notebook computer, so he has to go through the Dragon's USB to get to anything at all. avrFreak
