Part Number: AFE4404EVM
Other Parts Discussed in Thread: AFE4404

The AFE4404evm Guide mentions that there EVM has SFH7050 and BMA280. 

It says if to use SFH7050, R1, R3, R5, R7,  and R9 should be installed. How?

Also, for BMA280 how to access its output?

    Hi Hazem,

    Please refer to figure 77 in the AFE4404EVM user guide for the sensor board schematics.

    The accelerometer BMA280 footprint has been provided in the sensor board. You can access the acceleration data through the i2c interface.

    This requires modifying the MSP430 firmware to support the accelerometer.

    Note that we do not support the accelerometer firmware update and leave it to the user for further development.

    Hello Parveen, 

    Thanks a lot for responding soon. I read a similar reply concerning the Accelerometer before. My main problem is that I am not familiar ar all with MSP MCU programming and I don't have the tools for it since my resources are limited nowadays.

    Also, giving the fact that all I have is the AFE4404EVM which is hardwired, I don't want to risk changing the firmware as I learn. Can you provide the same firmware included for the standard AFE4404EVM but with BMA280 management/access module for just getting raw data?

    Hi,

    You should be able to download the AFE4404 EVM firmware from the AFE4404EVM tools folder at ti.com.

    Here is the link for your reference: https://www.ti.com/lit/zip/slac718

    Unfortunately, the firmware does not include the Accelerometer firmware and we do not support the Accelerometer firmware.
