I am running a simple loopback in preparation for doing some more complicated things over serial.
My Setup is a 90USB1287, in a STK525 on a STK500. This is then connected to a FT232R, and then my PC which is using hyperterminal.
Everything is working as expected, with one big catch. when I tx from hyper terminal this is what I get.
pls see attachment
As you can see the voltage is approx. between 1.5-3.3v instead of 0-3.3 as I expect it to be.
Thanks in advance.
