Part Number: CC2650
Other Parts Discussed in Thread: Z-STACK,

Hi,

1) Currently we are working with cc2650 sensortag , In sensortag we are running accelerometer mpu9250, SDAHP and SCLHP pins are muxed to 8 and 9, but it is not working , we are assuming that there is no support for I2C1 interface in contiki, Please suggest

2) we are also working with cc26xx-webdemo application, we followed the procedure as mentioned in the TI website to configure, but the sensortag is not connecting,when we open the web browser it is not able to connect . Please suggest

cc26xx-web-demo already enables accelerometer mpu9250 reading using I2C so you can study the source code.

1) Can You Please suggest how to enable the mpu9250 in contiki , I Think it is blocking in i2cbusy only. whether I2C1 interface is there in contiki

2) Webdemo application i not running , when we open the web browser it is not able to connect

1. Do you use "make TARGET=srf06-cc26xx BOARD=sensortag/cc2650 cc26xx-web-demo.bin" to build binary for CC2650STK?
2. Try to use nullrdc to test again.

Yes we are using make TARGET=srf06-cc26xx BOARD=sensortag/cc2650 in contiki_os/examples/cc26xx/cc26xx-web-demo/ here bin file is generation this bin file we are flashing into sensortag

Where do you build the binary? In InstantContiki?

0 anantha Umapathi over 8 years ago in reply to YiKai Chen

Intellectual 510 points

no in LINUX Environment we are building the binary

Try to do it in InstantContiki.

0 anantha Umapathi over 8 years ago in reply to YiKai Chen

Intellectual 510 points

NO i want to run on LINUX environment only, i can't do it on Instant Contiki, Please suggest some solution

Is there any changes required for i2c1 in contiki for running mma9250 accelrometer

mpu9250

0 YiKai Chen over 8 years ago in reply to anantha Umapathi

Guru 735685 points

I suspect this is tool chain issue so I suggest you to use InstantContiki to verify it.

0 YiKai Chen over 8 years ago in reply to anantha Umapathi

Guru 735685 points

There's no need to change anything for i2c in contiki for running mpu9250 accelrometer

0 anantha Umapathi over 8 years ago in reply to YiKai Chen

Intellectual 510 points

can you please share the contiki source for me to work on it

0 YiKai Chen over 8 years ago in reply to anantha Umapathi

Guru 735685 points

I use the source code at github.com/.../contiki

0 anantha Umapathi over 8 years ago in reply to YiKai Chen

Intellectual 510 points

we are also using same source but mpu9250 is not running, from board_i2c_write function it is not returning , it is strucked here only, how to solve this issue

Do you try to build binary on InstantContiki?

0 anantha Umapathi over 8 years ago in reply to YiKai Chen

Intellectual 510 points

we dont have that much of time to do in instant contiki, so iam asking for linux environment, Is there any alternate for this , I need only accelerometer in cotiki

0 YiKai Chen over 8 years ago in reply to anantha Umapathi

Guru 735685 points

You are wasting your time. The fatest way is to try InstantContiki.

0 anantha Umapathi over 8 years ago in reply to YiKai Chen

Intellectual 510 points

can you share the process of instant contiki
