REALIZE SIMPLE HMI INTERFACE USING LINUX AND ODROID c1+ DEVICE WITH TOUCHSCREEN SHIELD

Realize a graphical touchscreen interface (using odroid c1+ touchscreen shield) for visualize and set signals according further requirment. - Each signal has an unique ID - For digital and analog signals is possible to read or write the values using the ID and an internal webserver (localhost). to write a signal value: [login to view URL] to read a signal value: [login to view URL] Where xxxx is the ID of signal. The signals ID and definitionis are stored in a xml file. This is an example: <SHOW> <SIGNAL_SHOW> <SIGNINF ID0='9995' Dir='1' Type =’1’ Min='-10' Max='50' Step='1' UniMis='°C' Des=’House Temp.' Rec='1' /> <PAGE Page='1' pos='1' column='1' /> </SIGNAL_SHOW> <SIGNAL_SHOW> <SIGNINF ID0='1002' Dir='1' Type =’2’ Min='0' Max='1' Step='1' UniMis=’0/1' Des=’Living Room' Rec ='0' /> <PAGE Page='1' pos='2' column='1' /> </SIGNAL_SHOW> <SIGNAL_SHOW> <SIGNINF ID0='1003' Dir='1' Type =’2’ Min='0' Max='1' Step='1' UniMis=’0/1' Des=’Bedroom’ Rec ='0' /> <PAGE Page='1' pos='3' column='1' /> </SIGNAL_SHOW> <SIGNAL_SHOW> <SIGNINF ID0='1243' Dir='0' Type =’3’ Min='-' Max='' Step='' UniMis='' Des=’Video1' Rec ='1' /> <PAGE Page='2' pos='1' column='1' /> <VIDEO Port='0' channel='1' /> </SIGNAL_SHOW> <SIGNAL_SHOW> <SIGNINF ID0='1244' Dir='0' Type =’3’ Min='-' Max='' Step='' UniMis='' Des=’Video2' Rec ='1' /> <PAGE Page='2' pos='2' column='1' /> <VIDEO Port='0' channel='2' /> </SIGNAL_SHOW> <SIGNAL_SHOW> <SIGNINF ID0='1245' Dir='0' Type =’3’ Min='-' Max='' Step='' UniMis='' Des=’Video3' Rec ='1' /> <PAGE Page='2' pos='1' column='2' /> <VIDEO Port='0' channel='3' /> </SIGNAL_SHOW> <SIGNAL_SHOW> <SIGNINF ID0='1246' Dir='0' Type =’3’ Min='-' Max='' Step='' UniMis='' Des=’Video4' Rec ='0' /> <PAGE Page='2' pos='2' column='2' /> <VIDEO Port='0' channel='4' /> </SIGNAL_SHOW> <SIGNAL_SHOW> for each signal that Program must put in the interface Program’ll have a SIGNAL_SHOW node </SIGNAL_SHOW> In the example xml Program see listed signal ID= 9995, R/W (dir=1=R/W; dir=0=R),Analog (1=analog;2=digital;3=video;4=audio), recording activated (1=recording activated). PAGE node says that HMI Software has to visualize the button of signal 9995 in page 1 pos=1, column=1. signal ID= 1002, R/W (dir=1=R/W; dir=0=R),Digital (1=analog;2=digital;3=video;4=audio), not recording (1=recording activated). PAGE node says that HMI Software has to show the button of signal in page 1 pos=2, column=1. signal ID= 12343, read only (dir=1=R/W; dir=0=R),Video (1=analog;2=digital;3=video;4=audio), recording (1=recording activated). PAGE node says that HMI Software has to visualize the button of signal in page 1 pos=2, column=1. I have in mind simple HMI pages like that showed in IMAGES 1-2 IMAGE 1 IMAGE 2 Shape of buttons depends on SIGNAL TYPE (Square for Analog, the other for digital).Little red circle says that recording is activated on that signal. - If someone push a digital or analog button HMI Program must give the possibilty to change the value. For analog Program can use the triangle at the side for changing values. - If XML signal definition will change my program will restart HMIprogram restarting it. - Normally the screen has to show a default image (I’ll send Program that) that has to change at the first touch as showed before. - For video signal HMI Program have to show a an image with a specific name from files stored in a specific directory. I'll let available the odroid remotely in ssh.
