PmodAD5

Question

Hello new to Digilent and PmodAD5,

Looking for advice and help on picking right micro-controller or components to capture data coming out of PmodAD5.

Background

I want to capture data coming form Gyro (http://www.analog.com/en/products/mems/mems-gyroscopes/adxrs649.html#product-overview) with the the PmodAD5. Wanted to know what micro-controller you guys would recommend for this task. 

I am familiar with MSP430 launchpad and very familiar with Arduino.  I just want to get something up and working to get familiar with PmodAD5.

Any help wound be great

Thanks

Hi Jrlin,

Truthfully speaking, any microcontroller that can communicate over the SPI interface (which is what the PmodAD5 uses to communicate) can work very well with the PmodAD5. Some details on how you might get it up and running can be found from our reference manual and this forum thread. Unfortunately, we don't have any code examples for the Pmod at this point in time.

Personally, I would use a chipKIT uC32 since that is what I am most familiar with. It can be programmed in a very "Arduino-like" way and is pretty powerful for what it is. But if you already have a couple of microcontrollers of your own on hand and they have standard SPI capability, you will be good to go.

Let me know if you have any more questions.

Thanks,
JColvin

Hello,

PmodAD5 is powered by Analog Devices AD7193.

On Analog Devices side we can find plenty of documentation for this device, including some usefull drivers / libraries / demos. For example here https://wiki.analog.com/resources/tools-software/uc-drivers/microchip/ad7193  you can find a chipkit driver and a demo using ChipKIT MX3: http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,892,1217&Prod=CHIPKIT-MX3.

Or you can check  the Digilent chipkit libraries for similar SPI devices like PmodAD1: http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,401,499&Prod=PMOD-AD1

Good luck.

If you are willing to pay a tiny bit more... I would suggest the WF32. It's just like the uC32, but it's a lot more powerful and includes WiFi for later projects (it also has a very forgiving voltage/ current tolerance for higher power projects).
