u16_get_listen_duration_ms()

Description

u16_get_listen_duration_ms() returns the time [ms] that the bootloader waits for bootloader protocol messages on the CAN bus (MCAN0) at start up.

Syntax

u16_get_listen_duration_ms();

Parameters

none

Returns

uint16_t – the listing time in milliseconds.

Example Code

This example shows how to read the ‘listen duration’ value of the bootloader settings.

void setup()
{  
  Serial.begin();
  while (!Serial) 
  {
    yield(); // wait for PC CAN2SER-monitor to open 
  }

  Serial.println("Current bootloader settings:");
  Serial.print(" - listen duration: ");
  Serial.println( String( BOOTLOADER_SETTING.u16_get_listen_duration_ms() ) + " ms");
}

void loop () 
{
}

Notes and Warnings

This method returns the RAM copy value of the bootloader settings which are copied into the BOOTLOADER_SETTING object during its instantiation at system start (variant.cpp).
