Description
Technical field
The present invention relates to a kind of DSP burning device, especially a kind of portable DSP cd-rom recorder based on serial ports.
Background technique
General DSP burning mode mainly has emulator programming, or runs burn recording software as host computer by computer and pass through string
Mouthful, the progress burnings such as CAN mouthful.These traditional burning modes are all completed on computers, disadvantage: greatly, again due to computer volume
Amount weight, even laptop, which also carries out DSP upgrading to the product of site of deployment, makes troubles.
If application number 201711069157.X is for defect existing for tradition DSP burning, devises and a set of have while burning
The replication tool and method for burn-recording of two DSP abilities are recorded, replication tool includes: DSP burning interface, and the USB for connecting host computer connects
Mouthful, USB turns double-serial port module, and power control module receives the low and high level signal of the DTR pin from serial ports, according to described
Low and high level signal control dsp processor powering on and powering off, mode control module: receiving the height of the RTX pin from serial ports
Low level signal realizes the switching between DSP burning mode and normal operation mode according to the low and high level signal.It is beneficial to effect
Fruit is: greatlying simplify the operating procedure of traditional method for burn-recording；Can simultaneously two DSP of burning；It will need originally manually
The acquisition version number and verification operation that can be completed are automatically completed by upper computer software.
For another example, application number 201611108191.9 proposes program burn writing method, apparatus and vehicle in a kind of DSP, the DSP
Middle program burn writing method includes connection DSP and host computer, and detects whether that there is the programming for carrying out programming to program in DSP refers to
It enables；It when there are programming instruction, generates and prohibits Yan Zhiling, wherein prohibit speech instruction for forbidding in the affiliated CAN network of DSP, remove DSP
Equipment in addition sends message；Speech instruction will be prohibited and be sent to equipment, and need the target program of burning according to programming command reception
Source file；The file format of source file is converted, the program after being converted, and according to the program after conversion to DSP
Middle program carries out programming.The probability that program upgrades successfully can be effectively improved through the invention, reduces network load rate, improve journey
Sequence burn writing speed reduces the update time of program.
Summary of the invention
It is existing to be applicable to products application for the purpose of the present invention is to provide a kind of portable DSP cd-rom recorder based on serial ports
The DSP burning of field, to facilitate burning personnel to operate.
The purpose of the present invention is realized by following proposal: a kind of portable DSP cd-rom recorder based on serial ports, including DSP are burnt
Main control chip is recorded, using USB flash disk as the carrier of program, the main control chip is connected by pressing key control by RS485 and power interface
Connect battery supply and a RS485 connector；Main control chip drives USB flash disk by a USB interface through USB flash disk driving chip, operates shape
State is shown by LED1, LED2.
On the basis of above scheme, the Master control chip is mounted in shell, and RS485 and 5V electricity is arranged in shell one end
USB interface is arranged in source interface, the other end, and key and LED light are located at housing mid-section position.
On the basis of above scheme, the port A, B of the Master control chip connection RS485.
The present invention supports USB flash disk to plug, and program file there are in USB flash disk, present device insertion is needed to upgrade by user
Equipment, entire burning process can be automatically performed by clicking button.It can be used for laboratory burning, be more suitable for products application scene
DSP burning, greatly facilitate staff's burning operation.
The present invention has the advantage that
1. it is small in size, it is light-weight, it is easy to carry；
2. carrier of the USB flash disk as program, storage and replacement are extremely convenient；
3. click keys is needed to start, escalation process can be automatically finished.

Specific embodiment
Such as the stereoscopic schematic diagram 1 of the present invention of attached drawing 1, the stereoscopic schematic diagram 2 of the present invention of attached drawing 2 and 3 invention's principle block diagram of attached drawing
It is shown, a kind of portable DSP cd-rom recorder based on serial ports of the present invention, including DSP burning main control chip, using USB flash disk as program
Carrier, the main control chip are connected battery supply with power interface by RS485 and a RS485 are patched by pressing key control
Part；Main control chip drives USB flash disk by a USB interface through USB flash disk driving chip, and mode of operation is shown by LED1, LED2.
As illustrated in fig. 1 and 2, the Master control chip is mounted in shell 1, setting RS485 and the 5V electricity of 1 one end of shell
USB interface 3 is arranged in source interface 2, the other end, and key 4 and LED1, LED2 are located at the intermediate position of shell 1.
As shown in figure 3, whole equipment of the present invention mainly has one piece of DSP burning main control chip, LED1 and LED2 it is respectively red,
Green indicator light, 4, RS485 connectors of a key, main control chip connect USB interface component, equipment through USB flash disk driving chip
It is powered by 5V battery.
Compact of the present invention, it is easy to carry；As long as program file there are in USB flash disk, present device is inserted by user
The equipment for needing to upgrade, entire burning process can be automatically performed by clicking button 4.Suitable for laboratory burning, it is more suitable for
The DSP burning at products application scene.
