RESPONSE OF THE EA eDIPTFT43-A VIA SERIAL INTERFACE
The table below contains all response codes. Some response data will come automatically some
others on request. In addition to that with command 'ESC SB ...' user is able to transmit individual data
packages. All reponses are placed into the sendbuffer. With the smallprotocol command ’Request for
content of send buffer’ (see page10) the host can read out the sendbuffer. This can be done per polling,
alternativly pin 20 ’SBUF’ shows with LO-signal that data is ready to transmit.

Responses of the EA eDIPTFT43-A
Remarks
Response from the analog touch panel when a key/switch is pressed. code = down or up code of the
key/switch. It is only transmitted if no touch macro with the number code is defined !
When a bargraph is set by touch, the current value of the bar no is transmitted. Transmission of the bar balue
must be activated (see the 'ESC A Q n1' command).
After the input port is changed, the new 8-bit value is transmitted. The automatic port scan must be activated.
See the 'ESC Y A n1' command. It is only transmitted when there is no corresponding port/bit macro defined !
When a keystroke of the external matrix keyboard is detected, the newly pressed key number no is
transmitted. Only transmitted if no corresponding matrix macro is defined !
The following is transmitted in the case of a free touch area event: type=0 is release; type=1 is touch; type=2
is drag within the free touch area at the coordinates xx1, yy1
After the 'ESC B S n1' command, the current value of the bar with the number no is transmitted.
After the 'ESC A X' command, the current status (value=0 or 1) of the touch switch code is transmitted.
After the 'ESC A G nR' command, the code of the active touch switch in the radio group no is sent.
After the 'ESC Y R' command, the requested input port is transmitted. no=0: value is an 8-bit binary value of
all 8 inputs. no=1..8: value is 0 or 1 depending on the status of the input no
After the 'ESC V D ch' command, the requested voltage of channel ch=1..2 will be sent (value = 0..5000mV)
After the 'ESC V S ch' command, the requested voltage of channel ch=1..2 will be set as scaled ASCII
characters (length of string = num-1).
After the 'ESC S V' command, the version of the edip firmware is transmitted as a string
e.g. "EA eDIPTFT43-A V1.0 Rev.A TP+"
After the 'ESC S J' command, the macro-projectname is transmitted. e.g. "init / delivery state"
after the 'ESC S I' command, internal information is sent by eDIP (16-Bit integer values LO-HI Byte)
Version: LO-Byte = version number Software; HI-Byte = Hardware revison letter touch
Touchinfo: LO-Byte = '-|+' X direction detected; HI-Byte = '-|+' Y direction detected
DFlen: number of user bytes in data flash memory (3 Bytes: LO-, MID- HI-Byte)
after the 'ESC UH....' command, a hard copy is sent in G16-format.
xx1,yy1 = Start coordinates of the hard copy (upper left corner)
B5
Remarks
Set brightness of the LED illumination n1=0 to 100%.
Increase brightness of the LED illumination (one step=1%)
Decrease brightness of the LED illumination (one step=1%)
Time n1=0..31 in 1/10sec for changing brightness from 0 to 100%
LED n1=0: OFF; n1=1: ON; n1=2 to 255: LED switched ON for n1/10sec
Assign bar no=1..20 for changing brightness of the backlight
Save the actual brightness and changetime for poweron to EEPROM
n1=0: Set all 8 output ports in accordance with n2 (=8-bit binary value)
n1=1..8: Reset output port n1 (n2=0); set (n2=1); invert (n2=2)
n1=0: Read all 8 input ports as 8-bit binary value (to sendbuffer)
n1=1..8: Read input port <n1> (1=H-level=5V, 0=L-level=0V)
The automatic scan of the input port is n1=0: deactivated; n1=1: activated
The input port is n1=0: normal; n1=1: evaluated inverted
Specifies an external matrix keyboard at the inputs and outputs.
n1=number of inputs (1..8); n2=number of outputs (0..8); n3=debouncing (0..7)
input port n1=1..8 is assigned by falling edge n2=0 to new BitMacro number n3=0..255
input port n1=1..8 is assigned by rising edge n2=1 to new BitMacro number n3=0..255
Assign keynumber n1=1..65 with matrixmacro number n2=0..255
After release the key n1=0 run matrixmacro number n2=0..255
Set a new RGB value for color no. n1=1..32 (R5:Bit7..3; G6:Bit7..2; B5:Bit7..3)
Wait n1 tenths of a second before the next command is executed.
For RS232/RS485 operation only and only possible when Hardware address is 0.
The eDIP is assigned a new address adr (in the Power-On macro).
The tone output (pin 16) becomes n1=0:OFF; n1=1:ON; n1=2 to 255:ON for n1/10s
num (=1 to 255) bytes are sent to the sendbuffer data... = num Bytes.
In the source text of the macro programming, the number num must not be specified.
This is counted by the ediptftcompiler and entered.
The version is sent as a string to sendbuffer e.g. "EA eDIPTFT43-A V1.0 Rev.A TP+"
The macro-projectname is sent as a string to the sendbuffer e.g. "init / delivery state"
Internal information about the edip is sent to the sendbuffer.
