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
