Modifying the sample accelerometer code (ez430-rf256x)

Guys please help,
I'm just loosing my mind here..... 

Sanat, 

I will try to help you. For a start, try looking at http://processors.wiki.ti.com/index.php/CC256x_MT_UART_BRIDGE#appl_spp.c

There are many place in the code where data is being sent so you need to uncomment them.

Hey Zahidul,

                       Thanks a lot for the reply.

I did the changes described in the wiki but while running the code, it gets trapped in "sdk_error_handler()". What should i do ?? 

Can you tell me all the changes you've made to the original ez430 project since sdk_error_handler() is called from many places. Also the main function is only used once at the beginning for initialization. Then any other processing would take place in "tasks" for example, in user_task_routine()in user_task.c which runs periodically. I would comment out all the appl_send_spp_data() to stop continuously sending accelerometer data and modify the code to call it in user_task_routine() instead.

I fixed that problem, that was happening because i had included the wrong .lib file.

but still its not working completely.

i have also done the ez430 modifications given on the wiki so i could send uart data through my pc hyper-terminal, but on the other side i don't receive anything. When i run the code it connects with the other bluetooth and then i send data through uart but i don't get anything on the other bluetooth module and after sometime it goes in to low power mode.

also i have the sample accelerometer code on the receiving side, could it be happening because of that ??

i put a led notification function inside "USB_UART_ISR" to see if it's receiving data through my pc hyperterminal, but it turned out that its not even going into ISR.

and i understand that "appl_send_spp_data()" function is used to send spp data but in the modification it had commented all four of these functions in "appl_spp.c", So how is it sending spp data ??

also can i send uart data through IAR workbench and debug at the same time ?? 

I have attached the modified files. could you please take a look??
i'm really sorry i have too many doubts, I really appreciate your help.

Hallo,

I can't find the sourcecode of accelerometerwith Blutooth stack for ez430-rf256x, can you tell me where I can download it?

Hey Misha,

you can find the code here.
scroll down and download EZ430-RF256X-SDK-GA software.

And how can I compile this for ez430-rf256x? Can you tell me step by step what I have to do?

I have instaled EZ430-RF256X-SDK-GA, and iar v. 5.40 msp

I open EZ430-RF256x IAR Workspace, and download the programm accl on the board, leds (red and blue) is blinking. Debugging shows an error???

What do I wrong???

PS: I habe two ez430-rf256x (one on battery, one on usb), habe I download the same code on bouth boards, ore have I to change configs in somewhere, something like master and slave?

Misha, 

This wiki should gives a tutorial on running the demo: http://processors.wiki.ti.com/index.php/EZ430-RF256x#EZ430_Software

@misha : In your workspace there is a folder named "BT_Stack_Lib", it contains two lib files "CC2560.r43" & "CC256x.r43" you need to exclude the cc2560 file and include cc256x file. just right click go to options and include/exclude.

Hi all

I managed to program the msp430 demo accelerometer. I also made changes to the code dimensioned according to the guide, http://processors.wiki.ti.com/index.php/CC256x_MT_UART_BRIDGE

How can I modify the code to disable the accelerometer reading and send other information to another port on the ADC?

Hi,

I can't download the sourcecode of accelerometer with Bluetooth stack for ez430-rf256x in the "http://www.ti.com/tool/mt-bt-sdk", can you tell me where I can download it?

Regards,

Unfortunately, there is no more support for that code. I worked with this stack but there are things I do not like, besides the use of IAR only 30 days is a constraint. Try Bluetopia stack (http://www.ti.com/tool/stonestreetone-bt-sdk) or BTstack

Hi,

I have instaled the IAR and i very interesting in modify the accelerometer code to use the ADC's of my ez430-rf256x, but i don't have the accelerometer code and mt-bt-sdk. Can you tell me where I can download it? or can somebody provide me or send me?

Regards,

Hi

there it is!!

Thank you very much for the file.

Best Regards,

Thanks for provide this file

But there is another problem. After I intalled the application, I use FET-Pro430 and I choose "ez430-accl.d43"  complie to the board ez430-rf256x.

When the compile is finish, I find the the LEDs of Blue and Red are blinking. I think it's error condition. Can any one help me to solve the problem? Thanks!!!

Best regards,

Jack

Try creating the project. HEX, look here http://e2e.ti.com/support/microcontrollers/msp430/f/166/t/39835.aspx

Then use SmartRF Flash Programmer, and test again.

I follow these step to create .hex , but I can't find the .hex in folder. So I can't use SmartRF Flash Programmer  to choose the Flash image.

the following is the steps I tried.

1. install the accel demo

2. open the application by IAR (I only have the licence for 4K KickStart Edition, v. 5.51)

3. following the website  http://e2e.ti.com/support/microcontrollers/msp430/f/166/t/39835.aspx

I don't know how to solve the problem. Can someone give me some suggestions? Thanks.

Hi 

please try with IAR 30 days Kick Start Edition.  With this version you can debug and program the accel demo.

the .hex only is created if the program is compiled completely, and for this you need 30 days version kick start.

Hi

The following are my steps

1. try with IAR 30 days Kick Start Edition and I press "download and debug"

2. after the  program is compiled completely and I press "Project->Options->Linker->ExtraOutput" to output the Boot.hex

3. I use the SmartRF Flash Programmer to flash the image.

But the LEDs of BLUE and RED are still blinking. I think it's in error condition

Can some one give me some suggestions? Thanks

Check in your code if you have the correct library selected

My library seems is not correct. Can you tell me how to change to the correct library? Thanks

Sure!!
->left click over the file that you want to incude/exclude -> choose Options...-> click on checkbox Exclude from build 

Thanks a lot!!! It's work!!!!

And now I want to change the connection to point-to-multipoint  with 4 of the same boards.  Can you give me some suggestions?

I have read the "MSP430BT5190_CC2560_Developers_Guide".

And I find the command "SDK_INQ_MAX_DEVICES" is the following

Maximum number of remote devices (discovered during
Inquiry procedure) information stored by the local
device
Default:0x07 (Seven remote devices information)

So if I want to change the connection to point-to-multipoint, whether I just change the command  Default:0x07 (Seven remote devices information) ?

Hello,

Please note that we do not support MindTree's SDK anymore, we encourage you to evaluate using the latest StoneStreetOne's Bluetopia stack:

http://www.ti.com/tool/stonestreetone-bt-sdk 

Best Regards,

Hi 

I have finished the point-to -multipoint connection. 

Now, I want send data from Slave to Master and check  whether a piconet in the same channel by Tera Term.

I find the command of send data, but I don't know where can I set data parameter that I want to send.

Can you give me some suggestion?

Thanks.
