    4.1.2. Introduction to Cross-Compilation Generally, program compilation is performed by running a compiler on the build platform. The compiled program will then run on the target platform. Usually, these two processes are intended for use on the same platform. However, if the intended platform is different, the process is called cross compilation, where source code on one platform can be compiled into executable files to be used on other platforms.

  • Page 120: Building A Sample Mqtt Application Using Linpac

    7.3. Building a sample MQTT application using LinPAC MQTT (Message Queuing Telemetry Transport) is an ISO standard publish-subscribe based messaging protocol. It is a lightweight connectivity protocol for M2M (machine to machine) communication that works on top of the TCP/IP protocol. The protocol uses a publish-subscribe model for message exchange between machines, based on the efficient distribution of messages to one or many receivers through a broker.
  • Page 121 We use LinPAC series devices as both the MQTT client and the MQTT broker, and communicate through the broker to control the MQ-7255M module, as you can see from the architecture diagram in Figure 7.3-1, the LP-9x2x module is used as the MQTT client, and the LP-52xx module is used as the MQTT broker.
  • Page 122 As an MQTT client, the MQ‐7200M series module is able to publish messages that related to the status of the Digital I/O to a broker and subscribe to topics from a broker that are used to control the DO lines. In a similar way, other MQTT clients can obtain the status information from the Digital I/O by subscribing to a topic from the broker and then publishing messages to the broker that then control the DO lines, as illustrated in Figure 7.3-3.
  • Page 123 Step 1: Connecting an MQ-7255M module to a LinPAC MQTT broker. On the configuration page for the MQ-7255M module, first click the ‘MQTT’ option. Modify the configuration for the built-in web browser on the MQ-7255M module, as illustrated in Figure 7.3-4.
  • Page 124 Figure 7.3-5. Subscribing to a topic Step 3: Managing topics and publishing. On the LP-9x2x module, use the following command to publish a message from the LP-9x2x module to the MQ-7255M module via the MQTT Broker. mosquitto_pub -h <broker IP> -p 1883 -q 0 -t MQ7255M/SetValue/DO1 –m ‘1’ In this example, the topic being published is ‘MQ7255M/SetValue/DO1’.

    7.4. Power-on Value Settings This section will discuss the Power-on Value functions that are adopted in the Linux PAC. When the Power-on Value function is active, the DO or AO output will be restored to the preconfigured value if the power supply has an on/off switch. The following is an operational example using an I-87024W module inserted in an LP-8x21 controller.
  • Page 126 Step 3: Restart the LinPAC Switch off the LinPAC and then restart it. Channel 0 on the I-87024W module will output 2 V. Step 4: Confirm that the Power-on Value is functioning correctly Use the multimeter to measure the channel output voltage on the I-87024W module and verify that the voltage is the same as before the LinPAC was restarted.
