RE: Alternative WP34S flashing using Arduino
Hello I'm newer to the wp 34s spaces but I just got what I thought was all the pieces I needed to flash a HP 30b with the wp 34s rom. But I'm suck on mysymb step because both windows program don't seem to see the calculator. I tried with both an arduino and a ftdi cable from Amazon. Any help would be greatly appreciated!

Below is a picture of one of my tries with the ftdi cable.
Red = power +/-
White = RX
Black = TX

Second Image is arduino
Red = Ground
White = RX
Black = TX
