Can't communicate between STM32L and LSM303DLHC

Posted on January 23, 2012 at 11:59Hi all, I created a simple circuit connecting a STM32L151C6T6 to a LSM303DLHC accelerometer. They communicate using I2C interface. I made the first simple test program modifying I2C EEPROM example included in STM32...

Error ''Invalid ROM table'' for Keil ULINK debug interface

Posted on January 05, 2012 at 15:52Hi, I have the MCBSTM32F400 development board - this worked fine up to now. Now I wanted to write some new complex application (trying to ''re-target'' a USB MSC example of ST for this board). When I loaded the new...
