Rowetelposts some simple examples showing how to use the Codec 2 and FreeDV API in C and Python applications.
Some of the other examples have grown a little too full featured and complex so I thought it might be useful to show the simplest possible programs. Instructions at the top of each file.
The Quisk SDR is a fine example of a GUI application that uses the FreeDV API.
I’m intrigued by the idea of using the FreeDV API with other languages such as Python. I first became aware of this idea through this FreeDV KISS TNC project from xssfox.
Using similar techniques Mark, VK5QI, has implemented a High Altitude Balloon (HAB) telemetry library using a fork of C modem/protocol code from Codec 2 combined with Python. The project includes a nice Python GUI application for receiving HAB telemetry.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
