Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-6 is please referred to, the present invention provides a kind of technical solution: a kind of parameter setter based on wireless telecommunications, including
Single-chip microcontroller 1,12864 liquid crystal displays 2,4*4 matrix keyboard 3, HC-05 bluetooth module 4 and the Bluetooth AP P5 for being mounted on mobile phone,
The model STC89C52RC of the single-chip microcontroller 1, and the output end of the input terminal of the single-chip microcontroller 1 and HC-05 bluetooth module 4 electricity
Property connection, the input terminal electric connection of the output end of the single-chip microcontroller 1 and 12864 liquid crystal displays 2, the single-chip microcontroller 1 and 4*4
The two-way electric connection of matrix keyboard 3, the Bluetooth AP P5 and HC-05 bluetooth module 4 pass through wireless connection.
The clock circuit of the single-chip microcontroller 1, the oscillating circuit of the clock circuit is using internal oscillator mode, and crystal oscillator
Mistake will be generated when effectively avoiding communication so as to accurately calculate the initial value of T1 timer for 11.0592MHz
The phenomenon that difference simultaneously accumulates it, and then bit rate generates mistake, influences the net synchronization capability of serial communication.
It is generated on the RESET pin of the single-chip microcontroller 1 and keeps the height more than clock cycle of 24 oscillation pulse periods 2
Level inputs the positive pulse reset signal that pulsewidth is more than 2 clock cycle, according to the pin of single-chip microcontroller 1 that is, on RESET pin
Position, it is effective to guarantee that single-chip microcontroller 1 active homing.
The parallel port mode that 12864 liquid crystal display 2 uses, is selected by PSB pin, set 1 be it is parallel, set 0
Then be it is serial, directlyed adopt the P0 of STC89C52RC 8 I/O ports driving, can show 4 rows 8 arrange amount to 32 Chinese characters, together
When, 12864 included character libraries eliminate the operation using Zemo modulus.
The HC-05 bluetooth module 4 needs interconnection with single-chip microcontroller 1, i.e. the TXD of bluetooth module connects single-chip microcontroller 1
RXDP30, the RXD of bluetooth module meet the TXDP31 of single-chip microcontroller 1.
The first row of the 4*4 matrix keyboard 3, which links together one end of each key, constitutes line, and first row will be every
The other end of a key, which links together, constitutes alignment, therefore total 4 rows 4 arrange totally 8 lines, by this 8 lines and 8 of single-chip microcontroller 1
I/O port connection when detection, is first classified as low level for first by detecting whether electrical level judging key is pressed, remaining is classified as high electricity
Flat, once whether each row has low level to Polling immediately after, if detecting, certain a line has low level, can determine column
Number, therefore obtaining is that the keys of which which column is pressed, so as to effectively reduce the use of I/O port.
The 4*4 matrix keyboard 3 is used to prevent keyboard from shaking by the way of software for jitters elimination, after judging by key pressing,
It goes to judge whether key is pressed again after waiting a bit of time, if so, being really to be pressed, is otherwise then considered as shake.
Working principle: before the use, function sets are carried out for all parts, 4*4 matrix keyboard 3 carries out setting four
Detection function, respectively jiance1 (), jiance2 (), jiance3 () and jiance4 (), respectively correspond detection the first row,
Second row, the third line and fourth line, and only read_ is just jumped out after changing the value of Keybord_value by key pressing
Keybord () function transfers to execute following sentence.
The written in code of HC-05 bluetooth module 4 has been related to register configuration and interrupt processing, before bluetooth, I
Need to initialize serial ports, configuration TMOD enables timer 1 as bit rate generator and being total to work in mode 2, then
TH1 and TL1 initial value is assigned, is 0xfd, then opening to interrupt allows, even TR1=1, reconfiguration SCON is 0x50, represents serial ports
Work is finally exactly out interruption and allows for, including REN, EA and ES, be to calculate in this way about TH1=TL1=0xfd in mode 1
: it is that the flood rate of T1 is exactly its inverse that timer, which overflows the primary time, and the bit rate of mode one is, here SMOD=0,
Therefore 2SMOD=1, it is obtained after known number is substituted into formula, solves X=253, corresponding hexadecimal is 0xfd, is being initialized
After serial ports, receives character and handled by interrupt function.Once there is character to send, the interruption of the interruption default of serial ports will be triggered
Serial number 4 will enter interrupt processing function.In the interrupt handling function, the character string received is stored in by I
In Bluetooth_Data array, and setting reception character denotation position is 1, and such single-chip microcontroller 1 can basis in major cycle
This flag bit is 1 parse to the character received.
In use, it is connect by Bluetooth AP P5 with HC-05 bluetooth module 4, the operation interface on mobile phone carries out
Setup parameter, mobile phone send the data to single-chip microcontroller 1 by included Bluetooth function, and single-chip microcontroller 1 receives after data to data
Carry out parsing and will be in processing result real-time display to 12864 liquid crystal displays 2.
It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
