Anthem serial command with variable

Denis · June 2009

Hi

I try to send a serial commande trough variable in an Anthem TLP1

the string has to look that TFP13 meaning set band1 (FM1) preset 3

I tried

//VARIABLE 
CHAR  nTUNER_PRESET_NUM
CHAR  nTUNER_PRESET_BAND

//CODE
BUTTON_EVENT [dvTP_TUNER,13]
{
	PUSH:
		{
		nTUNER_PRESET_BAND = 1
		}
}

BUTTON_EVENT [dvTP_TUNER,14]
{
	PUSH:
		{
		nTUNER_PRESET_BAND = 2
		}
}

BUTTON_EVENT [dvTP_TUNER,1]
{
	PUSH:
		{
		nTUNER_PRESET_NUM = 1
		}
}

BUTTON_EVENT [dvTP_TUNER,2]
{
	PUSH:
		{
		nTUNER_PRESET_NUM = 2
		}
}

BUTTON_EVENT [dvTP_TUNER,3]
{
	PUSH:
		{
		nTUNER_PRESET_NUM = 3
		}
}
BUTTON_EVENT [dvTP_TUNER,4]
{
	PUSH:
		{
		nTUNER_PRESET_NUM = 4
		}
}

BUTTON_EVENT [dvTP_TUNER,5]
{
	PUSH:
		{
		nTUNER_PRESET_NUM = 5
		}
}

BUTTON_EVENT [dvTP_TUNER,16]
{
	PUSH:
		{
		SEND_STRING dvTLP1, "'TFP',nTUNER_PRESET_BAND,nTUNER_PRESET_NUM,$0A"
		SEND_COMMAND dvTP_TUNER,"'@TXT',70,nPREAMP_BUFF"
    CLEAR_BUFFER nPREAMP_BUFF

		}
}

But I get an invalid parameter from TLP1

Any cue?

don't you just need the itoa? if I am reading your post correctly

  SEND_STRING dvTLP1, "'TFP',itoa(nTUNER_PRESET_BAND),itoa(nTUNER_PRESET_NUM),$0A"

or am I missing something?

Currently nTUNER_PRESET_BAND and nTUNER_PRESET_NUM are integers. When you use them to concatenate the string you are sending to the tuner they need to be converted to their ASCII equivalents. Thankfully the NetLinx function ITOA makes this nice and easy. If you use the code JohnMichnr suggested it should fix your issues.

Nice!

Thanks guys.

I tried ITOA but here is my error

SEND_STRING dvTLP1, "'TFP',itoa(nTUNER_PRESET_BAND), (nTUNER_PRESET_NUM),$0A"

Close. ITOA is a function that takes an integer as its parameter (which is the value inside the parethesis) and will return the ascii equivelent (which will sit where the ITOA is called from). Because you are converting two decimal values you need to call it twice:

SEND_STRING dvTLP1, "'TFP',ITOA(nTUNER_PRESET_BAND),ITOA(nTUNER_PRESET_NUM),$0A"
