Or, you can substitute
the SparkFun FTDI
Basic Breakout – 5V
DEV-09115 (you will
have to move a couple
of wires on the
breadboard for this
one, so pay attention).
Either of these options
will allow you to talk
to the BeAVR serial
port using the PC USB.
Our first use for
this will be to upload
YouSent.hex (located
in Workshop22.zip)
using AVRUP-V1
(Figure 18), as was
discussed last month.
Please check the
www.smileymicros.
com website because I
am working on an upgrade for AVRUP and may have further
instructions for the BeAVR by the time you read this.

Talking BeAVR
Notice in Figure 1 in the lower left corner there is a
connector with six wires heading out of the photo. That device
is the FTDI TTL-232R-5V USB to Serial cable that you can get
from www.ftdichip.com/Products/EvaluationKits/TTL-
Open the device in Simple Terminal (available from
www.smileymicros.com) and send a character. The
Receive box should show ‘You sent: x’ (where ‘x’ is the
character you sent). Well, I told you how busy we’d be
this month. Next month, we will continue with the BeAVR
and introduce a version of the design for a PCB — and this
BeAVR will have fangs! NV
