accelerometer of ez430-rf2560
ez430-rf2560 bluetooth evaluation tool has a built-in accelerometer sensor, according to the following link:
Does anybody know whether a user can write and run a customized program on ez430-rf2560 to control the accelerometer and read its data?
this is a evaluation kit, so why shouldn't the user not be able to write and run his own code on the hardware?
So, the answer to your question is: YES! Yes, you can program the MSP430BT5190 (mounted on the tool) with your own software and - i.e. only use the accelerometer and read his data and send it to the host PC via Application (Backchannel) UART.
Demo application source code including the MindTree's EtherMind Bluetooth stack can be downloaded from the following linkhttp://focus.ti.com/docs/toolsw/folders/print/mt-bt-sdk.html
You can find addtional technical info in http://processors.wiki.ti.com/index.php/EZ430-RF2560
Please note that we are about to release an updated code on January 2011.Regards,Nir
Thanks for your response. Will the upcoming release code as you mentioned be the demo application source code or the Bluetooth stack?
With the updated code, will I still be able to develop my own application codes on EZ430-RF2560?
Hello William,Any release (including the upcoming one) contains a full SDK (SW Development Kit) - MindTree Bluetooth stack and sample applications in source code.
The content of EZ430-RF2560 SDK is very similar to the content of MSP430 experimenter's board+PAN1315 SDK.(The main difference is the interface with the accelerometer sensor in the application layer)TI recommends doing the development with MSP430 experimenter's board+PAN1315 kit since it exposes most of the MSP430 interfaces. For addtional information on the kit, please refer to http://focus.ti.com/docs/toolsw/folders/print/pan1315emk.html
Thank you for your info.
I would like to understand the difference in terms of MSP430's interface with the accelerometer sensor, which you mentioned in your e-mail.
Do you mean that to develop application software to access the accelerometer sensor, a developer should use MSP430 experimenter's board+PAN1315 kit
instead of EZ430-RF2560 development tool, because EZ430-RF2560 SDK does NOT provide adequate API functions to let a developer implement application programs to
access the accelerometer sensor?
TI supplies the HAL files in source for both EZ430-RF2560 and MSP430 experimenter's board.You can develop your application on any of the kits.I want to highlight that the EZ430-RF2560 accelerometer (CMA3000-D01) is I2C based, while the MSP430 experimenter's board default accelerometer (ADXL322) is analog based.In addition, EZ430-RF2560 accelerometer supports 3-axis, while the MSP430 experimenter's board default accelerometer supports 2-axis.The MSP430 experimenter's board has an assembly provision for ADXL330 device to support 3-axis.
I've got RF2560 but accelerometer onboard is analogic. Why?
For accelerometer-only interface code (no BT) you should check out the examples for the CC2530ZNP, as it too uses the MSP430. I wrote those examples, and there are a few there that interface with the same accelerometer.
