|
|
* The main loop of the application.
|
|
* This initializes the units that do the actual work, and then loops in the background.
|
|
* Other units are:
|
|
* - dsp.c, containing all signal processing in RX and TX branches. This part runs on the second processor core.
|
|
* - si5351.c, containing all controls for setting up the si5351 clock generator.
|
|
* - lcd.c, contains all functions to put something on the LCD
|
|
* - hmi.c, contains all functions that handle user inputs
