I have the Fez Panda II Ultimate Kit. I’ve hooked up the Connect Shield and the Ser2USB E-Block. I’m running off USB.
My program is a simple loop that is writing the current time out the serial port.
If I don’t have the PC attached to the USB port on the Ser2USB E-Block the Tx led blinks brightly (strangely the Rx led blinks faintly at the same time, despite there being no Rx data).
I’ve verified the signal is getting to the E-Block okay and appears to be valid serial data.
When I hook up the PC, the E-Block is recognized and a serial port is created. But simultaneously the E-Block’s LED quit blinking. The signal is still getting to it but nothing seems to happen.
Have I overlooked some hardware configuration? Does the fact the Rx light faintly blinks in unison indicate a hardware failure of some kind?
