Human Machine Interface (HMI) is a graphical interface between the user and the machine that allows humans to interact with machines, thus helping us effectively control equipment as well as getting real time data acquisition. Nowadays HMIs are widely used in countless sectors like electronics, entertainment, automation, industry, military, medical, etc. A user-friendly HMI can help increase productivity by having a centralized control system. The MYD-Y6ULX-CHMI Display Panel introduced by MYIR is specially designed for HMI applications which is based on NXP’s i.MX 6UL / 6ULL ARM Cortex-A7 processors. It is ready to run Linux and consists of an MYD-Y6ULX-HMI Development Board and a 7-inch capacitive LCD mounting on its top. It is delivered with necessary cable accessories including one 12V/2A power adapter with four types of conversion plugs, one power switch cable and a quick start guide to help user start to use right away when getting it out of box. MYD-Y6ULX-CHMI Display Panel MYIR also offers an add-on optional IO board MYB-Y6ULX-HMI-4GEXP for the MYD-Y6ULX-CHMI Display Panel to further extend the functionality of the panel including one more Ethernet, WiFi & BT, USB based 4G LTE Module Mini-PCIe interface, Audio and GPIOs, thus making a complete solution for HMI applications. The IO board is delivered with one WiFi antenna and one 4G antenna but 4G module is told only as an option and user can contact MYIR for details. MYB-Y6ULX-HMI-4GEXP IO Board Let’s know more about the MYD-Y6ULX-CHMI Display Panel. The MYD-Y6ULX-HMI Development Board can support DC 12V~24V power supply. It is built around the MYC-Y6ULX CPU Module which has a compact design, measuring only 37mm by 39mm. It has integrated the i.MX 6UL/6ULL processor, DDR3, NAND FLASH/EMMC and was well soldered onto the base board through its 1.0mm pitch 140-pin Stamp Hole (Castellated-Hole) Expansion Interface which is cost-effective but with high reliability and strong vibration resistance. The 7-inch LCD provided by MYIR offers 800x480 pixels display resolution with a capacitive touch screen. Separate the LCD from the MYD-Y6ULX-HMI board, we can see on the back of the board there is one LCD interface (16-bit RGB), one capacitive touch screen interface and one resistive touch screen interface. The i.MX 6UL/6ULL series processors can support maximum 1366 by 768 pixels display resolution. On the MYD-Y6ULX-HMI board, from left to right, we can see one 2-pin 3.81mm pitch phoenix connector for 12V~24V DC power input (one power switch cable was provided), one 3-wire RS232 serial port and one RS485 serial port from the 6-pin phoenix connector, one 10/100Mpbs Ethernet port, one USB Host port (Type A), one Micro USB OTG port and one TF card slot. Near the TF card slot, there is one 2.54mm 3-pin header for Debug port and RTC battery holder. On the other side of the board, there is one 8-bit parallel camera interface, buzzer and one reset button. The MYD-Y6ULX-HMI board has two 2.0mm pitch 2*20-pin headers for IO extension. The MYB-Y6ULX-HMI-4GEXP is just an IO extension board designed by MYIR. The MYD-Y6ULX-CHMI is ready to run Linux operating system. MYIR has built an application demo MEasy HMI to run on this platform. The MEasy HMI is a frame of human-machine interfaces which contains a local HMI based on QT5 and a Web HMI based on Python2 back end and HTML5 front-end. The dependency software includes dbus, connman and QT5 applications, python, tornado and other components. The MEasy HMI block diagram is shown as below: The MEasy HMI uses D-Bus as the access interface for the QT application and the underlying hardware. MYIR provides a complete set of control and communication interfaces for RS232, RS485, CAN and LED and encapsulates the interface into a library for external use based on D-BUS Method and Signal. The MEasy HMI uses Connman to control network devices. Connman is a fully modular system that can be expanded by plug-in to support the management of EtherNet, WIFI, 3G/4G, Bluetooth and other network devices. The directory structure of MEasy HMI is shown as below. User can get more information about the MYD-Y6ULX-CHMI from MYIR’s website: http://www.myirtech.com/list.asp?id=604

TensorFlow Provides a very simple ML by Java Script. It is easy to have the environment to see it demo. This document is to introduce it. The formula to get the training data We have a formula Y = 2X – 1 to get the training data example: let x=-1 then Y = 2*-1 – 1 = -2 – 1 = -3 x = { -1, 0, 1, 2, 3, 4} y = {-3, -1, 1, 3, 5, 7} Build up a very simple network model.add(tf.layers.dense({units: 1, inputShape: [1]})); This network will get training and predict the result for Y = 2X – 1 Should remind you here is the Machine do NOT know about the formula. It cannot calculate like us. The complete code <html> <head>   <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs@0.11.2"> </script> </head> <body> <div id="output_field"></div> <div id="output_field1"></div> </body> <script> async function learnLinear(){ const model = tf.sequential(); model.add(tf.layers.dense({units: 1, inputShape: [1]})); model.compile({ loss: 'meanSquaredError', optimizer: 'sgd' }); const xs = tf.tensor2d([-1, 0, 1, 2, 3,4], [6, 1]); const ys = tf.tensor2d([-3, -1, 1, 3, 5,7], [6, 1]); await model.fit(xs, ys, {epochs: 500}); document.getElementById('output_field').innerText = model.predict(tf.tensor2d([10], [1, 1])); } learnLinear(); </script> <html> Adjust the training to see what happen We will go to change the following code to adjust the training, then let machine tell the result for X = 10 to see if the training result is different or not. The result by calculation is Y = 2X – 1 = 2X10 -1 = 19 await model.fit(xs, ys, {epochs: 10}); We will try 10, 100, 500 and 1500. The result summary Y = 2X – 1 = 2X10 -1 = 19 10 : 13.9085026, 10.9296398, 13.0426989, 12.0150528, 7.4879761 100 : 18.0845203, 17.7116661, 17.9885635, 17.9806786, 18.2209091 500 : 18.9848061, 18.983654, 18.9877472, 18.9812298, 18.9825478 1500 : 18.9999866, 18.9999866, 18.9999866, 18.9999866, 18.999986 With 1500 training, the machine can predict the result very closely. But it cannot reach the correct result 19. Because the machine doesn’t know about the formula Y = 2X - 1

Imx6 can output lvds direct.But the lvds-wire is too expensive to buy. So they can cannect ds90ub947 serializer to applied in automotive instrumentation. By the way, it need a ds90ub948 deserializer in the remote which cannect a lvds displayer. The attachment is the driver of ds90ub947/948 for linux.It can support linux 3.10 and above.It was verified working on linux 3.10.53 and imx6q. The attachment list: ds90ub947.c ds90ub947.h readme.txt You can follow the readme to use it. This driver was barely in embryo.You should modify it according to your application. Sometime, it very looks like the ds90ub913/914 and max9286/96705.

As i.MX6 empowers the Surveillance applications, iWave has developed a system that brings together video streams from four cameras on four i.MX6 Pico ITX SBCs placed in four different locations through Ethernet. The fifth Pico ITX captures the video streams from the Ethernet and displays on a single HDMI monitor as indicated in the following block diagram. The system requires five i.MX6 Dual Pico-ITX boards connected with LAN. Each of four boards are connected with cameras which capture the video, encode and streams it as RTP packets. The fifth board receives four streams of RTP packets and displays to four slots in HDMI. Operating system used is Yocto of Dora Version. MIPI or CSI cameras can be used for the video capture (tested with 5MP MIPI camera). All the four cameras share the screen equally and the display resolution of each camera is 854x480. For ease of demonstration we have used one Pico-ITX per camera, however for real life scenario and to keep down costs there is a possiblity that each i.MX6 Pico-ITX SBC can be connected to two cameras. Each pico-itx with i.MX6 quad/dual core can capture video from two cameras simultaneously. The same streaming procedure needs to be followed for this scenario too with it appropriate IP and Port number. For more details please reach to mktg@iwavesystems.com
