Embodiment III:
UARTs, which are one type of asynchronous serial communication protocol, operate on the principle that each character of the transmitted data is transmitted bit by bit.
Wherein each bit has the following meaning:
start position: a logic "0" signal is first sent to indicate the start of a transmission of a character.
Data bits: immediately after the start bit. The number of data bits may be 4, 5, 6, 7, 8, etc. to constitute one character. ASCII codes are commonly used. The transmission starts from the lowest order bit and is clocked.
Parity bits: after the data bit is added with the bit, the bit number of the '1' is made to be even (even check) or odd (odd check) so as to check the correctness of data transmission.
Stop bit: which is an end flag of character data. May be a high level of 1 bit, 1.5 bits, 2 bits. Since the data is clocked on the transmission line and each device has its own clock, a small out-of-sync between the two devices in the communication is likely to occur. The stop bit is thus not merely indicative of the end of the transmission, but provides an opportunity for the computer to correct clock synchronization. The greater the number of bits available for the stall bit, the greater the tolerance for different clock synchronizations, but the slower the data transfer rate.
Idle bits: in a logic "1" state, indicating that no data is being transferred on the current line.
Baud rate: is an indicator for measuring the data transmission rate. Representing the number of symbols transmitted per second (symbol). The amount of information (number of bits) represented by a symbol is related to the order of the symbol. For example, 256-level symbols are used for transmission, each 8 bits represents a symbol, the data transmission rate is 120 characters/second, the baud rate is 120baud, and the bit rate is 120×8=960 bits/s. The concepts of the two are easy to be misplaced;
compared with IIC, UART can use single TXD (Transmit (tx) Data) as unidirectional communication, and directly Transmit Data according to slave machine through a certain baud rate. The received Data is only the Data on RXD (received) Data, and the received Data is converted into corresponding characters according to a certain baud rate. So the UART is provided with two data lines, the TXD of the slave is the RXD of the slave, and the RXD of the master is the TXD of the slave.
Fig. 6 is a schematic diagram of a communication baud of a sphygmomanometer according to a third embodiment of the present application, which performs handshake interaction through UART communication.
Handshaking interactions through UART communication include mode entry acknowledgements and communication baud acknowledgements.
The mode entry acknowledgement is the same as IIC communication, and the SDA is changed to TXD and the SCL is changed to RXD, and specifically, reference may be made to fig. 4 and fig. 5, which are not described herein.
Here, performing handshake interaction baud confirmation through UART communication includes:
the calibrator and the sphygmomanometer send a string of character strings to confirm the baud rate;
giving a blood pressure meter with a calibrating instrument TXD 'GOADJ';
after the sphygmomanometer RXD, TXD 'ACK' is given to the calibrator;
after calibrating the machine RXD, the TXD 'OK' is given to the sphygmomanometer;
after the sphygmomanometer RXD, TXD "ACK".
