TABLE 2 ADS1115 analog to digital conversion chip Pin Specification
The ADS1115 analog-digital conversion chip pin diagram of the table 2 and the pin function description of the table 2 are adopted by the driving device to transmit data, by looking at the circuit diagram of the Tiny4412 development board and the circuit diagram and the user manual of the Exynos4412Soc, the 0 th channel bus interface of the I2C controller for the user is left on the Tiny4412 development board, the analysis is available on the core board circuit diagram, the Xi2cSDA0 pin and the Xi2cSCL0 pin are respectively obtained by the EXYNOS4_GPD1_0 and the EXYNOS4_GPD1_1 pin with multiplexing functions through the designated functions, and simultaneously, the driving device has pull-up resistance, in the circuit diagram of the bottom board, after 1.8V voltage of the Xi2cSCL0 pin and the Xi2 c0 pin on the core board is converted into 3.3V voltage through the TXS0108 level conversion chip, the interface is provided for the user to be connected with the S1115 pin and the ADSDA pin, and the hardware SDA is completed as shown in the diagram 3;
when the host computer and the slave computer carry out data transmission, the protocol standard of the I2C must be strictly complied with, FIG. 4 describes a complete I2C communication process, when the I2C bus interface is not operated, the I2C bus interface is usually in a slave mode, when the clock signal SCL is at a high level, a start signal is generated through the transition from the high level to the low level of the data transmission line SDA, when the clock line SCL is at the high level, the data transmission line SDA jumps from the low level to the high level, when the host computer or the slave computer generates a starting condition, the I2C bus interface is changed into the host mode, meanwhile, the SCL starts to generate the clock signal, the I2C bus is in a busy state, and the I2C bus is in an idle state under the stopping condition;
when the host generates a start signal, the host should send a slave address to inform the slave, the host sends a field of a byte, the byte includes a 7-bit slave address and a 1-bit transmission direction indicator bit, when the 8 th bit is 0, a write operation (send operation) is indicated, when the 8 th bit is 1, a request to receive data (receive operation) is indicated, each byte length transmitted on the SDA line should be 8 bits, there is no limit on the number of bytes in each transmission process, but after the start condition is generated, the first byte sent must have information such as the slave address, when the I2C bus is operated in the host mode, the host sends an address field, each byte is followed by an ACK bit, and the I2C controller sends the most significant bits of the data and address bytes to the SDA data line, see fig. 5 for details;
before any read and write operations are performed on the I2C bus, the I2C controller must be: writing a slave address into an I2CADD register, setting an I2CCON register to enable receiving interrupt, defining the clock frequency of SCL, setting an I2CSTAT register to enable serial output, when an I2C controller receives data in a receiving mode, an I2C bus interface continuously waits until the I2CDS register reads new data, after reading the data, the I2C controller releases the SCL clock line, exynos4412 keeps the interrupt to identify receiving the new data, a CPU reads the data from the I2CDS register after receiving the interrupt request, completes the reading flow, and is described in detail in FIG. 6, the slave address of the device can be known to be 0x48 according to the previous introduction of an ADS1115 chip, so that in the I2C communication process of bottom hardware, a host computer forms 0x48 and low-level 0 (write flag bit) into one byte of data and places the data on an ADS1115 register one bit after the other, after the ADbit is written into an ADbit configuration data line, and after the ADbit is written 8 is written into the ADS1115 register one bit, and a serial signal is required to be read after the serial read and the serial signal is written from the SDA 48, and the serial signal is required to be generated after the reading is switched from the low-level 1;
the kernel driver of the ADS1115 chip is developed based on an I2C subsystem of the Linux3.5 version kernel, firstly, in the Linux platform, there are two ways to describe all hardware resources of the hardware platform, one is defined by a device tree, the other is defined by a board level, the design adopts the latter to define the ADS1115 hardware device, a file map tiny4412.C defining the board level resources is modified in a source code system catalog of the Linux kernel to add elements into a structure body array of an i2c_board_info type, each element in the structure body array represents all slave devices under an I2C bus interface 0 channel, the name of the added ADS device is defined as 'ADS', and by consulting a chip manual of the ADS1115, if an ADDR pin of the ADS1115 chip is connected to a GND line, the slave address of the device is 0x48, then the driver of the device is further designed, each channel of the chip is further described in detail, and thus an ADS 1115_for the detailed structure body type is designed, as shown in a detailed structure body information table of a I2 c_info type is shown in a table 2 c_info;

After the designed device structure body and the device data structure body variables are instantiated, the designed device structure body and the device data structure body variables are added into a device structure body array of a kernel, so that when a Linux system is started, the kernel initializes all device members in the device structure body array, puts ads1115 device members on an I2C bus of the Linux kernel, writes device driving according to an I2C bus device model, introduces an I2C bus device driving model of the Linux kernel in a second chapter, and firstly needs to define a structure body with the name ads1115_driver type of i2c_driver and initializes a probe member method, a remove member method and other members of the structure body;
in the I2C bus device driving model, when a device driving module is loaded to a kernel, the device driving module obeys a matching rule and automatically searches for devices mounted on an I2C bus to match, the device driving module can rely on the names of all devices in an id_table to match in the process of searching for the devices, in an ads1115_driver structure body variable, the id_table variable is assigned to be 'ads 1115' and 'ads 1015', and by virtue of the design, the driving module is enabled to adapt to two types of analog-to-digital conversion chips of the ads1115 and the ads1015, so that the driving module has universality;
once the device driver is successfully matched with the device, the kernel will call the probe function pointer of the i2c_driver structure to further operate, in this design, the ads1115_probe function is assigned to the probe function pointer, in the ads1115_probe function, a character driving device named as "ads1115" is registered by using a set of registered character driving interfaces provided by the Linux kernel, the chip is further configured by the previously defined ads 1115_plane_data variable, finally, the device re-implements the file_operations structure to redirect the read-write operation, the structure members are shown in table 5,

In view of the above design, the design flow and working process of the integrated ADS1115 analog-to-digital conversion chip driver are shown in FIG. 7, firstly, the driver is compiled into a kernel module, the module is loaded into the kernel by using a module loading command, and the driver drives the device to start working to provide service for an application layer;
the server is connected to the patient end and used for performing remote transmission on the acquired pulse data, is built on a Tiny4412 embedded development board, is developed by means of a Linux operating system, is designed by adopting a C/S architecture model, and provides various services for the client end;
in the Linux operating system, a Linux kernel encapsulates operation related to network communication and provides an interface related to network programming for a user to use, the Linux operating system abstracts a communication endpoint into a socket, the socket conceals most communication details of network communication, and the user can communicate with different hosts like an operation file;
the local server of the design adopts TCP/IP protocol to communicate, and the following process is generally required for establishing a server model under a Linux operating system: firstly, a Socket for communication is established, the Socket is assigned with a communication domain, then the Socket is bound with an address and a port, then the Socket is monitored to a local port, a client is waited for connection, if the client tries to establish connection, a new communication Socket is obtained by a server, and at the moment, the server and the client can communicate;
according to the drive design of the ADS1115 chip and the interface provided by the device driver, the pulse data after the analog-to-digital conversion of the device is read, after the device driver is loaded, a character device named as an ADS1115 is generated under the/dev catalog of the root file system, the operation of the device is as the operation of a file at an application layer, the device is firstly required to be opened, then the reading operation is carried out, because the kernel driver has defined a data format, the application layer needs to read according to the data format defined by the kernel layer, and the data can be forwarded by combining the two with the design of a server by combining the last section;
according to the simple introduction of the data format, the server program sorts and forwards the pulse data provided by the driver program, and as the ADS1115 analog-to-digital conversion chip selected before is 16 bits of converted data width, the unsignedshort data type is selected, in the design, an array of unsignedshort type with the length of 3 is used for receiving the data, the detailed information of the data packet is shown in fig. 8, the server is designed and built by combining the data packet format, and the server building flow is shown in fig. 9;
the server program is developed under Ubuntnn 18.04 operating system on virtual machine software of PC, and the server should run on Tiny4412 embedded development board, the two platforms are different, one is x86 platform and the other is ARM platform, so the server program can not run on ARM platform,
typically, a source program needs to be compiled to generate an executable file, a suite used for compiling is generally called a tool chain, the tool chain used on a PC host is a tool chain based on an x86 platform, if an executable file capable of running on an ARM platform is to be compiled, a cross-compiling tool is used to perform re-compiling, a target program different from the host architecture can be compiled on the host by using the cross-compiling tool chain, in the present design, since the target platform is the ARM platform, a 5.4.1 version ARM-linux gnueabi cross-compiling tool provided by the Linaro project group is selected,
recompilation of the server program via the ARM-linux-gcc tool chain, which can run on an ARM platform;
the doctor end is connected to the server, developed by combining a Qt integrated development environment with a network and a database, and used for receiving pulse data issued by the server and realizing the visualization of the pulse data;
the doctor end is used as a client end of a local server and receives data of the server in a network transmission mode, and the server adopts a TCP/IP protocol to transmit the data, so that the client end also complies with the TCP/IP protocol, the client end is developed under the Qt integrated development environment of a Windows operating system, in a Qt program, a QTcpsocket object is firstly instantiated to establish connection with the server, and a building flow is shown in figure 10;
after the qtcpsocet object is bound to the server address and port, a connectitopest () method is used to send a connection request to the server, after the connection is successful, the server sends data to the client or receives data through the Socket object, thanks to the signal and slot mechanism of the Qt program, when the Socket obtains the data sent by the server, a readyRead () signal is triggered, at this time, the slot function bound to the readyRead () signal is called, in the corresponding slot function, the read () method in the qtcpsocet class is called to read the data received by the Socket,
