Command Set for EA HMI Series

Answer / Feedback (proprietary interface Short/Small Protocol only)

The module places information in its send buffer after requests or touch events. Below the individual responses from the send buffer are explained.

The responses are binary encoded unless otherwise stated:

<ESC> = 0x1B, the size (number of bits) of each parameter are given in the explanation of each response.

The module works with little-endian (Intel-format), that means the least significant byte is transferred first.

EditBox

Touch

Variables/Registers

RTC

File access

System commands

EditBox content

The content of the EditBox (16 bits per character) is transferred. The string ends with a $ 00. The feedback is triggered by keyboard code 13 ($0D).

State of button/switch

The state of a button / switch (Obj-ID) is transferred. Which events (down, up, drag) lead to the sending of the feedback is set with the #TCR command. If no responses are to be transmitted via the serial interface, this is done with #TCR 0,0,Obj-ID.

Radio group active switch

The active switch (Obj-ID) of a radio group (Group-ID) is transmitted with every change. If no answers are to be transmitted via the serial interface, this is done with #TCR 0,0,Obj-ID1,...,Obj-IDn (all object IDs of the Radiogroup elements).

Keyboard key

The last key pressed (Code) on the keyboard (Obj-ID) is output. The prerequisite is that the keyboard is not connected to an EditBox. If no responses are to be transmitted via the serial interface, this is done with #TCR 0,0,Obj-ID.

Bargraph- /Instrument value

The new value of the BarGraph / instrument (Obj-ID) is output. Which events (down, up, drag) lead to the sending of the feedback is set with the #TCR command. If no responses are to be transmitted via the serial interface, this is done with #TCR 0,0,Obj-ID.

Menu entry

The selected menu item (ItemNumber) is output. Which events (down, up, drag) lead to the sending of the feedback is set with the #TCR command. If no responses are to be transmitted via the serial interface, this is done with #TCR 0,0,Obj-ID.

ComboBox entry

The selected SpinBox entry (ItemNumber) is output. Which events (down, up, drag) lead to the sending of the feedback is set with the #TCR command. If no responses are to be transmitted via the serial interface, this is done with #TCR 0,0,Obj-ID.

SpinBox entry

The selected SpinBox entry (ItemNumber) is output. Which events (down, up, drag) lead to the sending of the feedback is set with the #TCR command. If no responses are to be transmitted via the serial interface, this is done with #TCR 0,0,Obj-ID.

PictureBox entry

The selected PictureBox entry (ItemNumber) is output. Which events (down, up, drag) lead to the sending of the feedback is set with the #TCR command. If no responses are to be transmitted via the serial interface, this is done with #TCR 0,0,Obj-ID.

Number of string files loaded

The number of strings used from the string files is output.

Content from string register (ASCII)

The content (8 bits per character) of the string register (String-ID) and the Length are output. The string does not end with $00.

Content from string register (Unicode)

The content (16 bits per character) of the string register (String-ID) and the Length are output. The string does not end with $00.

Output register value

The contents of the register (Register-ID) and the Type are output:

Time ASCII output

The requested time is transmitted in the set format as ASCII. The string ends with a $00.

Time Unicode output

The requested time is transmitted in the set format as Unicode. The string ends with a $00.

Time binary output

The requested time is transmitted in binary format in the set format. Day of the week = 0 means Sunday

Current working directory

The current working directory is output.

All folders and files from directory (binary output)

All folders and files in the current working directory are output.

The time and date give the time stamp of the last change to the file.

All folders and files from directory (ASCII output)

All folders and files in the current working directory are output as ASCII strings.

All folders from directory (ASCII output)

All folder names in the current working directory are output as ASCII strings.

Folder/File information

Folder / file information is output.

The time and date give the time stamp of the last change to the file.

Data from file

The data from the file are output. Number indicates the length of the file.

Current project path

The current project path is output.

Version information

The version information of the display is output (e.g. "EA uniTFT V1.4 with capacitive touch")

Display information

Display information is output.

RAM memory information

RAM memory information is output.

SD-Card memory information

SD-Card storage information is output.

Hardcopy

A hard copy of the display content is output. The Header and Data depend on the selected format.
