Hello all,

I am trying to connect a sensor to the stm32f4 discovery board. what i want to do, i want to be able to write to the sensor and read from the sensor the data. would  you please guide me to any web resources or anything that would help me to do that on the discovery board. also is it possible to use the standard library (Hal library) to do that?

thanks guys.

Hi

Try these :

http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/PF252419

The WEB page for the STM32F4 board.

http://www.st.com/web/en/catalog/tools/PF257904

This page contains demo software to try on the board.

Lots of examples to try.

Hi

Yes, you are right. There does not appear to be an example of I2C in the demos.

Sorry.

Search the forum. There are hundreds of threads on I2C!

Look for example code from a guy calling himself 'clive1'

He generally does the best example code.

Hello,

The STM32CubeF4 contains some I2C example (Path: STM32Cube_FW_F4_V1.0.0\Projects\STM32F4-Discovery\Examples\I2C).

Even if the STM32F4 standard peripheral library is NRND, you still can download it from

http://www.st.com/web/en/catalog/tools/PF257901

. It contains some I2C examples (Project\STM32F4xx_StdPeriph_Examples\I2C) that you can update to use with your discovery board.
