I haven't used the Arduino Due lately, so I wanted to use it in the AD7849 DAC project which I wanted to use to generate carrier signal for AM transmitter based on Arduino Due and AD7840. But when I typed the board name it was not found. After quick search, I forgot that SAM ARM board library has to installed and so I installed from the library.
Now I want to test the Arduino Due to generate carrier signal in the AM frequency band 500KHz to 1.1MHz. So I tried many sine wave generator code like the one posted earlier in the guide Arduino Due Sine Wave Generator with Adjustable Frequency.
But I later found out that the maximum frequency that can the Arduino
Due DAC(Digital to Analog Converter) can generate is limited. So instead of Arduino Due, I used the code for Arduino Mega(which works for Uno, Nano board) that can generate square wave carrier signal in the AM band(500Khz to 1.2MHz approx). Meaning I used the code from the tutorial Arduino 8MHz Variable Frequency Generator.
