Antuino
Arduino+Si5351 = Antenna/Network Analyzer
Firmware Upgrade Process
-
On Windows, install the device driver for the CH340 / CH341 USB controller present on
antuino
using the following link.http://www.wch.cn/download/CH341SER_EXE.html
Note: A local copy of this driver is now included in this repository.
On Linux, the CH340 / CH341 USB controller works automatically.
-
Connect
antuino
to a PC using a USBA Male to Mini B
cable. External DC power is not required for programming the AA. -
Install
Arduino IDE
and open theantuino
sketch (antuino_analyzer_27mhz_v2.ino
) in Arduino IDE. -
In the Arduino IDE, select the following options.
-
Menu > Tools > Board = "Arduino Nano"
-
Menu > Tools > Processor > "ATmega328P (Old Bootloader)"
-
Menu > Tools > Programmers > "AVR ISP"
This
Processor
setting is valid for theantuino
version that was distributed during LARC 2019 event.https://www.arduino.cc/en/Guide/ArduinoNano has some additional details on this
Processor
setting. -
-
Upload the sketch to
antuino
using theMenu -> Sketch -> Upload
option in the Arduino IDE. -
After upgrading the firmware, run the
Calibrate SWR
menu option onantuino
. Note: Keep the antenna disconnected during this process. -
Reboot the antuino device. After the reboot, antuino is ready to be used.
Notes on powering antunio
The following power sources are stable:
-
USB 2.0 and USB 3.0 ports on Desktop computers
-
Chinese 6x18650 USB / 9v DC power banks
The following power sources are unstable:
- Small 9v battery
Notes
-
Anil Sharma (VU2TFG) reports that
antunio
SWR values are pretty close to the SWR values shown byGEK - 60MHz Antenna Analyzer by VU3GEK
.http://homebrewcorner.blogspot.com/p/page-update-642015-need-of-useful-tool.html
The GEK AA feels pretty solid and has a dual-digit SWR display (e.g. 1.82).
In comparison,
antunio
has a single digit SWR display (e.g. 1.8).The GEK AA is a fixed-function instrument and can't be programmed. In comparison, the possibilities are endless with
antunio
.
