I am sorry,but the development board does not have a ethernet connection.
Now we use CCS(code composer studio)to control the DSP,but I can not use CCS to creat a visual window which can be used to control the DSP conveinient.
Can I use visual basic to control the DSP by RS232?
I have a DSP(TMS320F2812) development board with a serial,so I want to use the serial to control the DSP and DAC to generate a pulse waveform.
How should I do?
Thank you very much.
Best regards.
I have done an experiment which can generate waveform from DSP and DAC,but the output waveform likes ladders when it up or down,especially when I stretch the waveform in the oscilloscope.
So how to improve the waveform?How to smooth it?
Thank you very much.
Best regards.
How can I design an adjustable voltage power supply?
The voltage of the power supply can be set from 0V to 100V.It should be very stable.
I want to get a design circuit of this power supply,than I can choose the component.
Thank you very much.
Best regards.
Thank you,everyone.
Dear FvM,Thanks for your advise,but now I can ont get the MJE340 and MJE 350,how about NTE39 and NTE157?

Thank you very much.

The maximum voltage we want to get is at least 100V,so where can I get the property transistor?
By the way,Q2 and Q3 are the same transistor,the supply voltage can lower than 230V.
I am sorry,but I can not insert the image.
Let me try it again.

Thank you,medxp.
Your design seems a little complex.We want to drive the piezo(PZT),so we need a 100V voltage.The signal which I have already described is a pulse waveform with the Vpp=5V,and there is no negative voltage.
I think we need a PZT(piezo) driver circuit,which can supply a hundred...
I want to use this circuit to achieve my aim,but the maximum out put voltage was only 15Vpp,the input waveform is a square wave 5Vpp,why?
And when I test the voltage between point a and b,it is only 16V,not 100V,why?
Could you help me?
Thank you very much.
Best regards.
