Model 2426 Multi-Function I/O Module

7.2.4 s2426_SetDoutMode()

Function:

Program the operating mode of one digital output channel.

Prototype:

BOOL s2426_SetDoutMode( SESSION sess, u32 *err, u8 chan, u32 mode );

Returns:

True if the operation was successful, otherwise False is returned and

err

will contain the associated error code.

Notes:

This function configures the operating mode of one digital output channel. Each channel can operate in either the
Standard mode or PWM mode. In Standard mode, the channel state can be manually programmed by calling

s2426_WriteDout()

. The state is automatically controlled by the I/O module in PWM mode, with duty cycle and

frequency programmed by calling

s2426_WritePwm()

Example:

// Configure channel 2 for PWM operation.

u32 err = ERR_NONE;

( !s2426_SetDoutMode( sess, &err, 2, DOUT2426_MODE_PWM ) )

printf( "Error: %s\n", s24xx_ErrorText(err) );

7.2.5 s2426_WriteDout()

Function:

Program all digital output channels.

Prototype:

BOOL s2426_WriteDout( SESSION sess, u32 *err, u16 states );

Returns:

True if the operation was successful, otherwise False is returned and

err

will contain the associated error code.

Example:

// Program digital outputs to 0x5A17.

u32 err = ERR_NONE;

( !s2426_WriteDout( sess, &err, 0x5A17 ) )

printf( "Error: %s\n", s24xx_ErrorText(err) );

Argument
