Functions
static bool_t	AR_Loopback_run ()
	AR_Loopback_run queries the user for the card, module and channel to configure the ARINC receiver as well as the data rate (high (100kHz) or low (12.5 kHz)). The receiving ARINC channel is configured for FIFO receive mode. This application also queries the user for the card, module and channel to configure an ARINC transmitter. In order for the receiver to receive data from the transmitter the receive and transmit channels must be connected externally. The receive and transmit functions may be set on the same channel, in which case the channel will perform an internal loopback and data sent will be received back.

ar429_loopback()

int32_t ar429_loopback

(

void

)

The purpose of ar429_loopback is to illustrate the methods to call in the naibrd library to configure two ARINC channels and transmit from one channel while receiving from the other. The two channels must reside on the same module for successful message reception.

The following system configuration routines from the nai_sys_cfg.c file are called to assist with the configuration setup for this program prior to calling the naibrd ARINC routines.

• DisplayDeviceCfg
