Description
Technical field
The utility model relates to a kind of teaching type ARM development board, specifically a kind of teaching type ARM development board based on LM3S8962 chip.
Background technology
In the epoch that IT infotech develops rapidly, ARM is mathematical starts the electronic product covering world's every field, compared to single-chip microcomputer, the advantage of ARM is: introduce operating system, i.e. direct developing application on an operating system, unlike single-chip microcomputer, all will be write again, the operating system transplantation work in early stage, and existing professional person carries out; Security performance is better, and kernel separates with the memory management of user's space, and system will be caused to die because of the single program error of user, this does not have in the software development of single-chip microcomputer; Efficient serviceability, introduces the management scheduling system of process, makes system cloud gray model more efficient, being the AM/BAM technology based on interrupting mostly, having limitation to the management of multitask in traditional microcomputer development; ARM chip is integrated into controllers such as SDRAM, LCD in the middle of slice, thin piece at hardware aspect mostly, at single-chip microcomputer machine, mostly will extend out.Therefore to student, the grasp of ARM chip and technology is necessary, very large advantage can be occupied in the process of stepping into society's job hunting.
Summary of the invention
The utility model provides a kind of teaching type ARM development board based on LM3S8962 chip, allows student well grasp the software and hardware ABC of ARM.
The utility model realizes with following technical scheme: a kind of teaching type ARM development board based on LM3S8962 chip, comprise LMS38962 chip, the CAN be connected with LMS38962 chip respectively, alarm module, AD load module, DA output module, data storage module, clock module, serial port module, touch-screen, USB module, display module, SD card module for reading and writing, power amplifier module and network interface module.
It is further: display module adopts numeral method module
The beneficial effects of the utility model are: student is on the basis of software and hardware ABC of having grasped ARM, after carrying out a large amount of actual combat real trainings, again to the knowwhy of ARM carry out certain deeply after, step into society and look for a pretty good work to be a thing easily.
Accompanying drawing explanation
Fig. 1 is the utility model theory diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, teaching type ARM development board based on LM3S8962 chip has a LMS38962 chip, the CAN be connected with LMS38962 chip respectively, alarm module, AD load module, DA output module, data storage module, clock module, serial port module, touch-screen, USB module, numeral method module, SD card module for reading and writing, power amplifier module and network interface module.
In the present embodiment, CAN module adopts the TJA1050 chip of NXP; Alarm module adopts 5V hummer, can realize ring and report to the police; AD load module, realizes the data acquisition of sensor; DA output module, can realize Single-chip Controlling peripherals; Data memory module, adopts the ferroelectric storage of FM25L256; Touch-screen adopts Beijing Di Wenke skill 7 cun of TFT touch screen; Clock module adopts SD2405ALPI chip, and system power failure clock does not stop timing; USB module adopts CH341T chip, powers, with dataphone to development board; Serial port module, adopts SP3232 chip; Numeral method module, adopts CH452 chip; SD module for reading and writing adopts CH376S chip; Power amplifier module, adopts TPA2005 power amplifier chips; Network interface module, adopts HR911105A network interface chip.
LM3S8962 chip is 32 RISC performance processor, 32 ARM Cortex-M3V7M structure optimization, the Thumb-2 instruction set of compatible Thumb improves code density, 50MHz running frequency, 1.25DMIPS/MHz, hardware division and monocycle multiplication, fast can nested interrupt, ~ 12 clock period, there is MPU protection setting access rule, 256kFlash, 64k SRAM, LDO able to programme exports 2.25V ~ 2.75V, support the access of non-alignment data, packed data is to internal memory effectively, support that bit manipulation uses internal memory to greatest extent, and provide the peripheral hardware of innovation to control.
