about PSoC development board power supply and communication with PC

[Anonymous]

It seems that PSoC is more convenient for developing data acquistion system. For CY8CKIT-050 PSoC® 5 Development Kit, should I order extra DC or AC adapter to power the board?

Can you give me some examples how to use C to program an application to transfer AD data from PSoC 5 to PC? I also want to control the sampling rate and sampling lengthe and even trigger from PC.

Thanks very much.

Best Regards,

The CY8CKIT-050 comes with a comes with everything that you need to work with the kit except for the DC adapter. The kit can also be powered using a standard mini USB cable. Please visit this page for information about this kit, http://www.cypress.com/?rID=51577.

   

Please visit the following webpages to get some code examples and App Notes, http://www.cypress.com/?id=2232&rtID=113 and http://www.cypress.com/?id=2232&rtID=76 .

We could help you better if you could clear the following:

   

What kind of Data Acquisition System are you looking to develop?(Digital,Analog or both?)

   

What is your mode of Data Transfer(USB or UART) ?

Thanks so much for your response. I want to mainly deal with Analog signal.

   

USB will be used.

In that case,I guess an Delta Sigma ADC component(perhaps an Analog Mux,for multiple channels?) and the USBFS configured for HID protocol should be it.

   

But you'll need to write an HID application on the PC side,but this is widely documented online.

   

You can find the relevant examples within PSoC Creator 2.0 itself,by right-clicking the component and clicking "Find Example Project".

   

Other resources that could help you,are

AN57473 - PSoC® 3 / PSoC 5 USB HID Fundamentals with Mouse and Joystick

   

(Since these are also in a sense analog data acquisition systems,they can be modified to suit your purpose.)

   

and if you want to learn about the USB protocol from scratch,among many other tutorials and writeups online,heres one from heres an appnote on the same.

Hope this helps.
