void AddChannel	(	Uint16	input,
		Uint16	channel,
		_iq	offset,
		_iq	gain
	)

Add channel to the AD module.

Parameters:

	input	input number (ADCINA0...ADCINA7, ADCINB0...ADCINB7)
	channel	set the S/H channel associated to the input.
	offset	offset in physical units
	gain	units/bits gain

Examples:

TIMotorLIBExample1/main.c, TIMotorLIBExample2/main.c, TIMotorLIBExample3/main.c, TIMotorLIBExampleHrdw/main.c, and TIMotorLIBExampleSw/main.c.

Definition at line 127 of file adc.c.

void AddUnipolarChannel	(	Uint16	input,
		Uint16	channel,
		_iq	offset,
		_iq	gain
	)

Add unipolar channel to the AD module.

Parameters:

	input	input number (ADCINA0...ADCINA7, ADCINB0...ADCINB7)
	channel	set the S/H channel associated to the input.
	offset	offset in physical units
	gain	units/bits gain

static void CalculateADClocks	(	_iq	fAD,
		Uint16	tSH,
		volatile Uint16 *	adcCLKPS,
		volatile Uint16 *	cps,
		volatile Uint16 *	acq_ps
	)			[inline, static]

Calculate needed prescaler values (cps, acq_ps) for the given frequency (fAD [Mhz]) and sampling time (tSH [ns])

Definition at line 34 of file adc.c.

void ConfigureAD	(	void(*)(void)	interruptFCN,
		_iq	fAD,
		Uint16	tSH,
		SEQ_MODE	seqMode,
		SAMPLING_MODE	samplingMode,
		SOC_MODE	socMode,
		Uint16	offtrim
	)

Configure AD module.

Parameters:

	interruptFCN	pointer to interrupt routine called on A/D finished conversion. If not desired pass NULL.
	fAD	desired AD clock in Mhz
	tSH	desired SH acquisition time in ns
	seqMode	INDEPENDENT_SEQ_MODE or CASCADED_SEQ_MODE.
	samplingMode	CASCADED_MODE or SIMULTANEOUS_MODE
	socMode,:	start of conversion modes PWM_SOC (start of conversion by pwm), GPIO_SOC (start of conversion by external GPIO) or SW_SOC (start of conversion by software)
	offtrim	AD offset compensation

Examples:

TIMotorLIBExample1/main.c, TIMotorLIBExample2/main.c, TIMotorLIBExample3/main.c, TIMotorLIBExampleHrdw/main.c, and TIMotorLIBExampleSw/main.c.
