UART via USB
EasyAVR
Enabling USB-UART
In order to enable USB-UART
communication, you must set J23
and J12 jumpers in the USB-UART
position, and enable desired RX
and TX lines via SW10 DIP switch.
For example, if you want to enable
USB-UART connection on UART
module of the default ATmega32
chip, you should enable SW10.1
(RD0) and SW10.2 (RD1) lines.

Modern PC computers, laptops and notebooks are
no longer equipped with RS-232 connectors and
UART controllers. They are nowadays replaced with
USB connectors and USB controllers. Still, certain technology
enables UART communication to be done via USB connection.
FT232RL from FTDI® convert UART signals to the appropriate USB
standard. In order to use USB-UART module on EasyAVR
microcontroller UART module. To establish this connection,
you must put J23 and J12 jumpers in the USB-UART
position, and connect RX and TX lines to the
appropriate pins of the microcontroller.
This connection is done using DIP
switch SW10.
