Interface Editing
Specialized interface editing software can quickly edit graphical
user interfaces GUIs and
applications The software contains universal
component tools which are divided into two
types control components and display components
Control components are input
objects Such as function
buttons sliders radio
buttons etc Display components
are output objects Like a bar chart
Numeric fields string
fields etc . By combining interface images
and processes and applying these component
tools edit and generate the interface that
users need .
communication protocol
In SP043T and embedded devices external
processors are used . Use ASCII or CRC based communication
protocols between them . The processor of the client device
needs to have the ability of RS - 232 serial communication .
The message of SP043T is initialized by a timer event or user input
from the touch panel .
Communication format
The communication between SP043T and external processors is
asynchronous serial transmission . Has the following format
Baud rate 9600 14400
19200 . 28800 38400 . 5600057600 . Or
115200BPS
CRC calculation
The CRC communication protocol uses a 16 bit CRC with cyclic
redundancy check.. To ensure the integrity of
data . Each sent message consists of a slave ID
an SP043T machine code and message
bytes . And the CRC of the last two bytes . Slave
ID SP043T machine code . The message byte
runs through the CRC algorithm . The generated 16 bit CRC is
added to the end of each message . most
The effective bytes of CRC are sent firs t.
When the host receives an SP043T message . The calculated CRC
should match the last two bytes . If not then the
packet should be considered incomplete data
