Response of EA eDIP240-7 via serial interface
data
Remark
Automatic response
Response from the analog touch panel when a key/switch is pressed. code = down or up
code of the key/switch.
Only transmitted if no corresponding touch macro is defined !
After a menu item is selected by touch, the selected menu item code is transmitted. Only
transmitted if no corresponding touch macro is defined !

no value
When a bar graph is set by touch, the current value of the bar is transmitted with no.
Transmission of the bar value must be activated (see the 'ESC A Q n1' command).
type

When automatic-open-mode for menu function is disabled (via command 'ESC N T n1'),
this request will be sent to host. Then it is necessary that host will open menu with
command 'ESC N T 2'.
The following is transmitted in the case of a free touch area event: type=0 release; type=1 is
touch;
type=2 is drag within the free touch area at the x,y coordinates (16-bit values)
Response only when requested
no
After the 'ESC N S' command, the currently selected menu item is transmitted.
no=0: no menu item is selected.
no value
After the 'ESC B S n1' command, the current value of the bar is transmitted with no.
code value
X-Pixel, Y-Pixel, Version, Touchinfo,
CRC-ROM, CRC-ROM reference
EEP in KB,
(abV1.4) CRC-EEP, CRC-EEP
reference, EEPcount
After the 'ESC A X' command, the current status of the touch switch is transmitted with code
(the return code). value = 0 or 1
(V1.3: count=14; V1.4: count = 21) After command 'ESC S I' eDIP sends internal information
(16-Bit integer Werte LO- HI-Byte)
Version: LO-Byte = Versionno. Software; HI-Byte = Versionno. Hardware
Touchinfo: LO-Byte = '-|+' X-axis; HI-Byte = '-|+' Y-axis
EEPcount: Couint of used bytes in EEPROM (3 Byte: LO-, MID- HI-Byte)
char. string...
After the 'ESC S V' command, the version of the eDIP firmware is transmitted as a string
(end code is the character NUL = $00). The first two bytes of the string always start with
'EA'
Response without length specification (num)
x1
y1
*.blh image data...
After command 'ESC UH....' is received a screen copy will be sent
x1,y1 = coordinates of the top left corner
*.blh image data: 2 bytes (width, height) + count of image data ((width+7)/8*height)
Note:
At pin 20 (SBUF), the display sets a low level to indicate that data is available to be fetched from the internal send buffer.
This line can, for instance, be connected to an interrupt input of the host system.
TERMINAL MODE
The display provides a terminal function. When
you switch it on, a cursor flashes in the first line,
indicating that the display is ready for operation. All
the incoming characters are displayed in ASCII
format on the terminal (exception:
CR,LF,FF,ESC,’#’). To achieve this, a correctly
functioning protocol frame is required (pages 8
and 9) or the protocol must be deactivated (close
solder strap J2, page 8 and 20).
Line breaks are automatic or can be executed by
means of the ‘LF’ character. If the last line is full, the
contents of the terminal scroll upward. The ´FF´
character (formfeed) clears the terminal.
The character ‘#’ is used as an escape character
and thus cannot be displayed directly on the
terminal. If the character ‘#’ is to be output on the
terminal, it must be transmitted twice: ‘##’.
The terminal has a separate output layer and is
thus completely independent of the graphic
outputs. If the graphics screen is cleared with ‘ESC
DL’, for example, that does not affect the contents
Terminal-Font (Font 0): 8x8 monospaced
of the terminal window. The terminal font is permanently in ROM and can also be used for graphics
output ‘ESC Z...’ (set FONT no.=0).
