Posted on October 24, 2013 at 19:28How the ''CMSIS'' and ''EWARM '' fields seen in ''workSpace window '' are added in a New IAR EWARM Project , what settings are used while creating project , any Example from ST for stm32xxx comes with a project whi...
Posted on August 30, 2013 at 00:22I am trying to interface LIS3DH Accelerometer over I2C to STM32l151rx series microcontroller , I am able to Read X,Y,Z register content , but i want to use the inbuilt motion detection interrupt feature of LIS3DH ...
Posted on September 23, 2012 at 23:13Are there any examples or application notes about how to execute a Code from internal Ram , i need to do IAP , but when programming flash from a flash based code , the controller hangs and even debugger can't ...
Posted on September 02, 2012 at 16:57Hello , I am developing firmware for an application , in which a 24 series eeprom and a GPS module is connected to same I2C bus of stm32l151 , stm32 will receive data from GPS as ''SLAVE ( DE...
Posted on May 26, 2012 at 16:53Hello, Is there any document that describes each Peripheral , and every bit of Register, for STM32f100x microcontrollers , there is nothing in Datasheet , for instance the USART is described only in 4 ...
Posted on September 17, 2013 at 13:17Finally i managed to enable interrupts , i use the application note AN3308 sequence for wakeup detection 1 Write A7h into CTRL_REG1// Turn on the sensor and enable X, Y, and Z// ODR = 100 Hz2 Write 00h into CT...
Posted on August 31, 2013 at 17:32 Have checked it by Reading back from initialization registers , all the values are being stored in Accelerometer registers correctly , Also i monitored the Interrupt signal on GPIO line on Scope , it is Constant...
Posted on October 11, 2012 at 09:22I modified the code to execute from internal Ram after copy , and its working fine , but i can't use debugger when executing from Ram , i am using ST LINK , when i am debugging the Ram based code , it will ne...
Posted on September 28, 2012 at 21:35Thanks clive, i found that there is __ramfunc directive to place code in ram , There are two parts of my code , one is the Main application and other the IAP , , the stm32l151 errata , CD00278726.pdf '' ultra lo...
Posted on September 15, 2012 at 22:52For now i have got EEPROM working by hibernating the GPS , although its not a solution , but for my purpose EEPROM will be only needed for Firmware Upgrade , so this can work
