Describe below in conjunction with an embodiment:
Communications protocol and data structure content:
Custom protocol:
1. the hardware of frame data transmitting-receiving is realized, realizes by the uart interface, and now general single-chip microcomputer all carries uart, so do not need extra hardware supported, cost is lower.
2. software is realized (configuration of signal, identification, processing and diagnosis)
2.1. data layout adopts 8 bit data of standard, each byte comprises identifier information and data message, and the byte number that every frame of data information comprises can freely define, and the speed of data transmission (baud rate) preferentially can change flexibly according to information.
2.2 for the reliability that guarantees to communicate by letter, data are adopted relatively stricter checking algorithm, adopt the crc check addition, as follows:
The CRC-16 sign indicating number is made of two bytes, and each of CRC register all is predisposed to 1 in when beginning, and (XOR: binary arithmetic is all 0 mutually, is not all 1 then CRC register and the data of 8-bit to be carried out XOR; 0^0=0; 0^1=1; 1^0=1; 1^1=0), afterwards the CRC register is shifted from high to low, position zero padding in most significant digit (MSB), and lowest order (LSB, be moved out of the CRC register after the displacement) if be 1, then register and predefined polynomial code are carried out XOR, LSB is zero else if, then need not to carry out XOR.Repeat above-mentioned displacement from high to low 8 times, first 8-bit data dispose, with this moment the CRC register value and next 8-bit data XOR and carry out as being shifted for 8 times the previous data.Value after all characters are finished dealing with in the CRC register is final crc value.
1. the CRC register is set, and gives its assignment FFFF (hex).
2. first 8-bit character of data and the least-significant byte of 16 CRC registers are carried out XOR, and the result is deposited in the CRC register.3.CRC register moves right one, LSB is shifted out and checks in the MSB zero padding.
3. if LSB is 0, repeated for the 3rd step; If LSB is 1, CRC register and polynomial code phase XOR.
4. repeating for the 3rd and the 4th step all finishes up to 8 displacements.This moment, 8-bit data disposed.
5. repeating for the 2nd to the 5th step all finishes dealing with up to all data.
6. the content of final CRC register is crc value.
CRC (16) polynomial expression is X16+X15+X2+1, and its corresponding verification binary digit classifies 11000000000000101 as.
7. data format definition
| D0 | D1 | D2 | D3 | D4 | D5 | D6 | D7 |
8. instrument is to the concrete representative information of controller data
Self-defined unibus asynchronous protocol:
Hardware aspect, in two and above Single Chip Microcomputer (SCM) system, can each personal io mouth as communication port.
The software aspect defines data and transmission mode in the following way
Bus level was defined as high level or low level when communication was idle, and the data level form can be defined by following manner during communication.Data 1 can be made up of 100us high level and 50us low level.Data 0 can be made up of 100us low level and 50us high level.Every frame data can comprise a plurality of bytes, and main frame can utilize free time to send data, does not additionally take mcu resource, has only a main frame in all single-chip microcomputers, comes issuing command information, coordinating communication by it.
One frame data transmitting time, calculate with byte 8 bit data, 8* (100+50)=1.2ms, can calculate the effective information that about per second can transmit 800 bytes like this, can be according to single-chip microcomputer performance and transfer rate and reliability requirement, but above-mentioned level definition time proper extension and shortening.
Data are sent completely the back transmit leg port are set as idle level, to discharge bus, finish this communication and wait for communication next time.
Reliability requirement according to data, latter two byte of data can be made as checking data, generally can for verification and or parity checking and crc verification etc., if wrongly can abandon these frame data, if think repair data, can carry out " cross interleave " to data, remaining data can be decided by the protocol definition person according to practical application request.
