Constant Field Values

SPROG_CS

public static final int SPROG_CS

Constant Field Values

PACKET_DELAY_WARN_THRESHOLD

public static int PACKET_DELAY_WARN_THRESHOLD

Threshold to warn of long delays between DCC packets to the rails. Worst case DCC packet transmission time is ~10 ms, which equates to 100 packets/s. Wait for a somewhat arbitrary time before reporting a possible issue with the system performance. A delay of 50 ms equates to 20 packets/s if sustained. Slower systems such as Raspberry Pi with flash based file systems are more likely to exhibit longer delays between packets.

CS_REPLY_TIMEOUT

public static int CS_REPLY_TIMEOUT

Timeout for command station to wait for reply from hardware. Slower systems such as Raspberry Pi with flash based file systems are more likely to exhibit longer delays.

TC_PROG_REPLY_TIMEOUT

public static int TC_PROG_REPLY_TIMEOUT

Timeout for traffic controller to wait for reply from hardware. Most replies are received from SPROG hardware with a few seconds, but paged mode programming operations can take considerably longer when reading a high value from a CV. Therefore we set a very long timeout, which should longer than the programmer timeout.

TC_OPS_REPLY_TIMEOUT

public static int TC_OPS_REPLY_TIMEOUT

TC_BOOT_REPLY_TIMEOUT

public static int TC_BOOT_REPLY_TIMEOUT
