The SARK110 SDK allows the development of user applications for the device or using the device as a platform for experiments.
The SDK provides the following basic functionalities:
• Graphic display
• Keypad
• Buzzer
• USB (Mass Storage Driver)
• DDS
• Timer
• ADC driver
• FAT file system
• Sample application
In addition the SDK provides a device simulator for developing the application on the PC, intended mainly for the development of the user interface of the application. This simulator requires the Microsoft Visual Studio (Visual C++) programming environment.
A CW beacon implemented in C language on a AVR AtTiny13A microcontroller (1KB flash!).
Include a CW parametric modulator/keyer, an emulated I2C periferal and a device driver in order to handle the Si570 oscillator by Silabs.
You can personalize the transmitted message and the morse speed (in WPM).
In the example the beacon is IQ6MC/B JN63RH @ 144.450MHz.
Enjoy this example and if you will appreciate it, please sens me a feedback!
