Hello RM,

I'm not sure that there is a sheild for the BMP085 sensor.

I used a Prototype PCB for Arduino and the BMP085 board. So I made my hown shield ;) .

You have an image of the board that I made.

PS: I have also another I2C sensor on the same board!

The small PCB is enough. I will buy one in tomorrow.

Hi RM,

Just want to know if you did have the time to buy and make some test with the sensor :) ?
regards,

Theo.

Hello All,

Just a small post to tell that I added to the trunk the support of the digital barometer and a demo to show how to read data from the sensor.

The code still need to be improve to add some feature such as the measurement of the altitude for example.

The driver for the BMP085 is located under os/ex/Bosch. You can find the following files:
    - bmp085.c
    - bmp085.h
    - bmp085.mk

The demo for the BMP085 is located under testex/STM32/STM32F4xx/I2C-BMP085/ here are the files for the demo:
    - Makefile
    - chconf.h
    - halconf.h
    - main.c
    - mcuconf.h
    - readme.txt

I have made the test, it works fine for me, and I want to tell thanks for the SHELL, it is so nice :lol: .

So Rocco Marco, I thinks that the sensor you purchase is already arrived, so can you give also a try? it would be good :)

Thanks.
regards,

Theo.

Thanks Theo,
your contribution is extremely appreciated.

I can provide you other MEMS if you want to help me to grow up EX.
Taking a look to the code.
Ciao,
RM

Theo,
I have aligned documentation. The code is really good but I can see a potential problem with compensation. Get in touch with me I have some suggestions.
Ciao,
RM

Hello Marco,

Thank you for your feed back.

I'm sorry I was not at home today, I went to visit my nephews :D and I had a good time with them.

It would be nice to help you to add more support to your sub-project.

For the potential problem, we will see together what to do so as you said, let keep in touch. I will be happy to hear about your proposition.

Thanks.
regards,

Theo.
