STM3220G-EVAL and LIS302DL

Hi,

I just got a STM3220G-EVAL board. I have to connect an I2C device, but first of all I'm trying to access via I2C the LIS302DL accelerometer on board.

Unfortunately, I can't find any example for that embedded device.

I tried to write some code using CPAL library sample but I never access the device.

Do I forgot something like positioning a jumper ?

Please help.

Regards.

Hi,

Thanks for your quick answer. I'll download the STM32F4 FW and test.

I'll come back to let youy inform of my research.

Regards.

Ok,

This sample demonstrates SPI communication to LIS302DL, but the STM3220G-EVAL has the LIS302DL connected via I2C according to the documentation.

So I try now to access the Audio Codec I2C regsiters and it's the same problem. I fall in timeout.

The only I2C devices I can read are the Expanders. Don't understand what is the problem.
