ADAS1000 TESTTONE output

Now I'm able to see a sine wave in 7,11,15,19,23 words, for both 150Hz and 10Hz.

Hi,

We have an example sequence in the datasheet on how to enable and measure the test tone. Please note that this example will only send 9 words which is different from table 22. 

Please see Example 4 in the datasheet ADAS1000/ADAS1000-1/ADAS1000-2 (Rev. C) (analog.com).

regards,

Mark

I'm using the example from the above link. And I'm getting the same output shown above from the example.

With the datasheet example 4 settings I'm stuck while Reading data, which is not my primary concern at the moment. 

I would like to understand the above data printed on the terminal.

This is the piece of code from the example printing on the terminal.

//Ouput the on the UART the frames read from the ADAS1000
	for(frame = 0; frame < 24000; frame++)
	{
		decimalToAscii(dataBuffer[frame], ascii);
		SCI_Write((unsigned char*)&ascii[0], 1);
		SCI_Write((unsigned char*)&ascii[1], 1);
		SCI_Write((unsigned char*)&ascii[2], 1);
		character = 0x2C;	// , (comma)
		SCI_Write((unsigned char*)&character, 1);
		character = 0x20;	// SP  (Space)
		SCI_Write((unsigned char*)&character, 1);
		if ((frame + 1) % 24 == 0)
		{
			character = 0x0D; // CR (Carriage Return).
			SCI_Write((unsigned char*)&character, 1);
			character = 0x0A; // LF (Line Feed).
			SCI_Write((unsigned char*)&character, 1);
		}
	}

This is my modified code from which I got the above output.

for(Frame=0;Frame<(24*ADAS1000_FRAME_READ_NO);Frame++)
	{
		decimalToAscii(Data_Buffer[Frame], Ascii);
		PRINT("%c",Ascii[0]);
		PRINT("%c",Ascii[1]);
		PRINT("%c  ",Ascii[2]);
		if((Frame + 1) % 24 == 0)
		{
			PRINT("\n\r");
		}
	}

Hi,

Please refer to Data Frames/Packets section of ADAS1000/ADAS1000-1/ADAS1000-2 (Rev. C) (analog.com) datasheet for details on how the frames are sent. This will be dependent on how the Frame Control register is configured.
