SYNOPSIS

#include "k8055m.h"

int
k8055m_set_digital_out_mode(int cardNumber, int port, int mode);

int
k8055m_get_digital_out_mode(int cardNumber, int port);
    

DESCRIPTION

k8055m_set_digital_out_mode() is used to set the mode of one of the 8 digital output ports. The possible values for mode are:

• K8055M_DIGITAL_OUT_MODE_NORMAL (0) - The port reacts to the usual k8055m_set_output(), k8055m_set_digital_out() etc. functions. Each time, the USB host computer needs a change in the logical 0/1 state of the output port, a USB message needs to be sent to the K8055M board.
  
  
• K8055M_DIGITAL_OUT_MODE_SERVO (1) - The port will operate as a standard hobby servo controller. It will send PWM pulses at a frequency of 40 Hz. The pulse width and direction will be controlled by the function k8055m_set_servo(). Once this mode and the pulse width are set, the K8055M will keep emitting 40 pulses per second without further communication from the USB host necessary.

RETURN VALUES

k8055m_set_digital_out_mode() returns 0 on success, -1 on error. k8055m_get_digital_out_mode() returns the current mode or -1 on error.
