The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the main TV structure schematic diagram according to controller of the present utility model;
Fig. 2 is the side-looking structural representation according to controller of the present utility model.
Description of reference numerals:
10, mainboard is controlled; 20, MCU card extender.
Embodiment
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As depicted in figs. 1 and 2, according to controller of the present utility model, comprise and control mainboard 10 and MCU card extender 20, control that mainboard 10 has first interface pin, the chip interface pin that MCU card extender 20 comprises with MCU chip connects and second interface pin that be connected corresponding to first interface circuit, and chip interface pin is converted to the change-over circuit of the second interface pin.By arranging MCU card extender, make selecting different MCU chip, only need to develop corresponding MCU card extender 20, and control mainboard 10 without the need to again developing, thus the compatibling problem solved between Chip scale that each MCU chip producer various can not be compatible, risk and impact that MCU chip exclusive supply brings can be reduced, save design and the test resource of exploitation controller, reduce costs.
Particularly, for different MCU chip, only need to develop a MCU card extender 20; This card extender 20 only realizes the switching of MCU chip pin function, and development amount is few.MCU card extender 20 can be general on the control mainboard 10 of correspondence, only needs the physical layer interface of the program to controller to be configured, complete corresponding software test.Save because certain master chip MCU needs to replace the pressure that the controller in enormous quantities brought needs exploitation, save design resource and the hardware reliability test resource of exploitation hardware pcb board.
In addition, MCU card extender 20 only relates to necessary crystal oscillating circuit, reset circuit, and the interface of chip pin, and development amount is few, and versatility is good, can save a large amount of development times, and the rapid batch realizing chip is replaced, the reduction construction cycle.Also the impact that chip exclusive supply produces is reduced to a certain extent, cost-saving.
Composition graphs 1 and Fig. 2 illustrate the performance history of the utility model controller, specifically comprise:
1, standard planning:
(1) planning defines standard set IO interface order, the function of interface is divided into by type: On-off signal DI, analog input AI, output switch parameter DO, analog output AO, notes the function mouth of specific demand.Such as, the function of each pin can be defined in the following manner, 1: general DI; 2: general DI; 3: debug signal input (special mouth); 4:GND; 5:+5V; 6:IIC-SCL (special DO); 7:IIC-SDA (special DI/DO); 8: general DI; 9: general DI; 10: hummer exports (special DO); 11: general DO; 12: general DO; 13: general DO; 14: general DO; 15: general DO; 16: general DO; 17: general DO; 18: remote control reception (special DI); 19: motor feedback signals (special DI); 20: general DO; 21: general DO; 22: communication RX (special DI); 23 communication TX (special DO); 24: general DO; 25: general DI; 26: general DO; 27:SPI-DATA (special DO); 28:SPI-CLK (special DO); 29: general AI; 30: general AI; 31: general DO; 32: general DO; 33: general DO; 34: general DO; 35: power detection signal (special DI).36: empty.
(2) type of attachment between planning control mainboard 10 and MCU card extender 20.Usual employing two kinds of connected modes, the first connects for adopting pad, and determine that the size of MCU card extender 20 is 45X25 millimeters, determine that the size of pad is 1X2 millimeter, spacing is 2 millimeters, and pad is distributed in the surrounding of MCU card extender 20; The second way is that the mode that the cushion of the row of employing connects carries out signal connection.
2, develop
(1) in the process of the controller of certain series of exploitation, according to size and the pin order of the IO interface defining interface of standard, a control mainboard 10 has been developed, such as: 1: switching on and shutting down signal input DI; 2: test signal input DI; 3: debug signal input (special mouth); 4:GND; 5:+5V; 6:IIC-SCL (DO); 7:IIC-SDA (DI/DO); 8: gate inhibition's signal DI; 9: push button signalling DI; 10: hummer exports (DO); 11: water valve control signal (DO); 12: the high-grade signal (DO) of blower fan; 13: the middle-grade signal of blower fan (DO); 14: the low-grade signal (DO) of blower fan; 15: display high-order (DO); 16: display low level (DO); 17: display lamp (DO); 18: remote control reception (DI); 19: motor feedback signals (DI); 20: communication polarity controls (DO); 21: communication receiving/transmission controls (DO); 22: communication RX (DI); 23 communication TX (DO); 24: communication pilot lamp (DO); 25: wire jumper information (DI); 26: motor control signal (DO); 27:SPI-DATA (DO); 28:SPI-CLK (DO); 29: temperature sensor (AI); 30: pipe temperature sensor (AI); 31: wind 1 (DO) swept by stepper motor; 32: wind 2 (DO) swept by stepper motor; 33: wind 3 (DO) swept by stepper motor; 34: wind 4 (DO) swept by stepper motor; 35: power detection signal (DI).36: empty
(2) develop a MCU card extender 20 according to the MCU chip selected, the two is assembled together by the interface of standard and carries out functional test and hardware reliability test.
(3) if need the MCU master chip changing other models, then develop the MCU card extender 20 of a correspondence according to the MCU chip of new choosing, the mode of the pin of the MCU of this model by standard interface is transferred.Because MCU card extender only relates to necessary crystal oscillating circuit, reset circuit, and the interface of chip pin, development amount is little, and test period is short.
(4) if develop the mainboard of other functions, also can select existing MCU card extender, meet the interfacing order of standardised generic.Namely a MCU card extender can be applied to the control mainboard 10 of many moneys difference in functionality, saves exploitation amount.
