BP-BASSENSORSMKII: Issue with BP-BASSENSORSMKII development board

Ismail Hossain

Part Number: BP-BASSENSORSMKII
Other Parts Discussed in Thread: HDC2080

Tool/software:

I am trying to connect with BP-BASSENSORSMKII development board with F28379D launchpad.

The example that has been made by Mathwork team is supposed to work. I did all the required steps, but still getting zero results.

Then I used I2C scanner example from Arduino, and it detects only 0x40 address (HDC2080) from the BP-BASSENSORSMKII development board. I gave the I2C address (0x69) for IMU according to datasheet but no result. Is (BOOSTXL-SENSORS) different than BP-BASSENSORSMKII?

Connection:

BP-BASSENSORSMKII plug-in module to the F28379D LaunchPad.

Connected GPIO104 and GPIO105 pins on the F28379D Launchpad to the J1.10 (SDA) and J1.9 (SCL) pins respectively on the BP-BASSENSORSMKII,

VCC = 3.3V

GND

My questions

Do you have any working example that can work with BP-BASSENSORSMKII sensors and F28379D?

Why the sensor module is only showing 0x40 address (HDC2080) instead of all other sensors I2C address?

Hi Ismail,

When connected to your Arduino, you have not supplied power to the sensors. See the schematic in the user's guide. https://www.ti.com/lit/slau829

If you need further support with the example code, I'll have to redirect you to the TMS320 team.

thanks,

Thank you so much for your response.

2.2.1 LaunchPad Development Kit Default Power Power is provided through the 3V3 (J1.1) pin on the BoosterPack plug-in module headers. The 3V3 pin powers everything on the BASSensors BoosterPack plug-in module.

In the datasheet, it is written that J1.1 pin that is connected with 3.3V powers everything.

Also, it is a plug in module, which I connected with F28379D Launchpad but was not able to test the C2000 example provided by MathWorks.

It would be helpful if you gave me any working example that this sensor module (BP-BASSENSORSMKII) works with the F28379D launchpad either in CCS or Matlab.

Again, thanks for your response.

I see now what happened here. The software for this BoosterPack was broken by an update and removed from the web instead of updating it. https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1068261/bp-bassensorsmkii-gui-composer-v2-example-for-bp-bassensorsmkii That means there is no example code for this BoosterPack.

At any rate, my previous point still stands. You will have to activate the GPIOs highlighted in yellow to power the sensors on this BoosterPack. That is just a fact of the PCB design. There's no point in arguing whether the design is right or wrong, because I don't disagree with you.

thanks,

ren
