Embodiment
One is independently tested and is joined hearing aids debug system, comprises upper computer software, data programing line, hearing aids; Its connected mode: connect upper computer end USB port by the USB port in line program, hearing aids connecting line connects hearing aids programming port, is illustrated in figure 1 the comparison of existing connected mode and connected mode of the present invention.In existing connected mode, coupling part forms USB or RS232 serial port connecting wire by 3 parts, the programmable device (as Hipro/Noah-link) of band USB or RS232 serial ports, line program.
Described upper computer software completing user listens the reading of inner parameter in the typing of force information and hearing aids, joins software as existing hearing aids manufacturer tests;
A kind of hearing aids line program with USB interface of described data programing line, be made up of USB interface, PL2303 transducer, control circuit, voltage stabilizing circuit, hearing aids line program, USB interface connects host computer USB port, the voltage signal that signal logic level conversion processing of circuit PL2303 transducer spreads out of, hearing aids line program is for connecting hearing aid programming interface.The difference of existing connected mode and connected mode of the present invention is to eliminate programmable device as seen from Figure 1, makes equipment be easier to carry, and connects debugging by the line program of a band USB.Saved by traditional programmable device, this is not simple by the function i ntegration of programmable device to hearing aids or in USB line program, but a kind of new debugging mode, and the debug process of traditional hearing aids is developed under the technical documentation provided according to chip manufacturer.The feature of the serial communication known by us based on the present invention carries out the development & production of hearing aids, thus reduces the cost in programming process.
Described hearing aids, it is the hearing aids based on serial communication chip development, turn serial port programming line by USB to be changed by the signal logic level shifting circuit that the digital data transmission of host computer turns in serial port programming line to USB, digital signal is passed to by hearing aids line program in the hearing aid chips of hearing aids processing unit after signal logic level shifting circuit is changed.Itself and the maximum difference of main flow hearing aid product are directly can be communicated by serial ports, do not need other reforming units (programmable device as existing hearing aids), essential core is computational methods in the chip of hearing aids and signal transacting, and the hearing aids of remaining parts and main flow is similar.Can divide 2 kinds of connected modes according to the configuration of existing market PC, 1 directly connects serial ports programmes, and 2 turn serial ports by USB carries out programme (considering that a lot of computer main board does not have serial ports now), and the present invention is example in a second approach.
Described hearing aids comprises hearing aid chips, microphone, receiver, battery compartment (power pack).
Described hearing aid chips is the chip based on serial communication, different from the support 2C of main flow on market or SPI communication modes.
Described host computer comprises PC, mobile phone, PAD.
Described data programing line operation principle: hearing aids passes through USB male joint socket by after conversion in the digital data transmission of host computer to the PL2303 transducer in USB line program, transfer signals to signal logic level shifting circuit again to change, digital signal is passed in the hearing aids dsp chip of hearing aids processing unit by hearing aids line program after signal logic level shifting circuit is changed.
Present invention provides enforcement principle, all kinds of component parameters is not illustrated, because can optimum selecting in actual production, be well known to those skilled in the art.The structure of data programing line is composed as follows:
1, this is USB male joint socket, can combine be connected with the USB female on computer, and D-, D+ are two FPDP of USB transmission, communication, as shown in Figure 2.
2, the effect of PL2303 is the conversion of communication modes, because present a lot of PC does not have serial ports, cannot carry out serial communication, so just carry out simulative serial port by the USB port of indispensability with MCU.Like this at MCU, oneself and PC are still carrying out serial communication.By PL2303, serial communication can be carried out and tested, as shown in Figure 3.
The effect of PL2303 is at simulative serial port, and digital signal level is packed by PL2303, is converted to usb protocol bag, then packet is issued PC, unpack reprocessing by PC.
3, logic level transition part, as shown in Figure 4.
PL2303 out be the Transistor-Transistor Logic level of 3.3V, in order to the pairing of DSP level, intercommunication needs to carry out level conversion mutually.Use 2 of NXP company two-way low-voltage converter GTL2002D.
4, voltage stabilizing circuit, uses AMS117_1.5, provides stable power supply, as shown in Figure 5 to DSP.
5, hearing aids line program is available to power supply and the communication interface of DSP, as shown in Figure 6.
