I've not done any real in depth programming for a good 5 years or more besides tinkering with simple things in the Arduino IDE here and there.
My programming knowledge is very very rusty these days - I'm practically back at noob level. Obviously the TX function wasn't designed to receive and handle data in this way and I'm not entirely sure what to do to alter it. RTTY.tx("Hello, this is a test message") Will Work The Arduino RTTY Transmitter Library will allow me to pass text (string?) messages to the TX function for it to "encode" into RTTY tones but it will not accept variable data directly e.g.
It does exactly what it says on the tin but not exactly what I want and I'm not quite sure how to modify it to do what I need. GitHub - farroid/arduino-rtty-transmitter: Simple RTTY transmitter for HAB and other applications The closest I've gotten to date has been using this very simple and lightweight library I found on GitHub called Arduino RTTY Transmitter. Many of these programs were designed to run "stand alone" and are far too heavy and complicated for my needs so I've had no luck in separating out just the TX side. I've been trying to adapt / modify / incorporate "out of the box" solutions such as MicroModem / Micro ARPS and many more of the popular TNC modem type software without much luck. Where I am now struggling is finding the easiest and lightest way to transmit bursts or packets of data collected during the day. Everything from that point of view is working - and has had months of testing. I have an SD card reader for reading from and writing to and I have all my TX hardware and code sorted. I use a real time clock to keep track of the real time and date. I have gotten everything else I require for my project working. What I've Tried, What I've Done, What Happened etc.
In my project I am hoping to include some self-monitoring (batt voltage, temp etc) and would like to have it take periodic readings throughout the day, store them and then transmit all the daily data back at a set time at the end of the day. Very Simple Requirements ( From My Point of View at Least) Then the nano trips an Opto Isolator to put the radio into PTT and the audio is generated from pin 9 on the Nano. The transmission and audio set up I am using at the minute is very simple.Īn arduino nano trips a relay which powers up the radio. My project already has radio transmit capability and audio output so ideally I'd like to make use of the existing hardware setup. I am working on a project in which I would like to include the ability to send periodic system health / status updates back to base over RF. I'm hoping you smart people can help me out here =]Ī Little Bit of Background Information & What I'm Trying to Do
