Posted on November 06, 2014 at 08:30Hello,We are planning to use STM32L151 Microcontroller for the GPS Tracker device application. One of our requirement is to update the firmware of the micro controller over the air. The device has a quad band GSM ...
Posted on October 30, 2014 at 16:03We are evaluating the STM32F4 products. For our current hardware an FPGA will generate measurement values. These values have to be transfered to an external RAM. Both are connected to the STM32 over the bus interf...

Posted on October 16, 2014 at 09:03I am trying to implement 3-phase BLDC drive signal based on Hall effect inputs. I chose TIM1 CH1(PA8), CH2(PA9) and CH3(PA10) as PWM outputs with complement output enabled (PB13, PB14 and PB15). TIM_OCPolarity and ...
Posted on November 06, 2014 at 22:23I have implemented a USB virtual serial port (CDC) device using the USB HS interface on an STM32F429 processor on an STM32F429I-DISCO evaluation board. The virtual serial port acts as a communication link between ...
Posted on January 08, 2014 at 16:43Hi All,I am using STM32F4Discovery board to log data from six analog channels at 50 KHz on micro SD card. Thanks to this forum for the help through various posts, particularly from Clive1. ADC operates in triple AD...
Posted on November 06, 2014 at 17:30Our design is operating properly on 3.1V PSU. When we try to start it with 2.9V PSU, it does not start.If we boot at 3.1 V and then reduce the voltage to 2.9V, it stops.The Brownout Reset (BOR) is set to 'disabled...
Posted on November 06, 2014 at 15:07Hello, I am designing a PCB for STM32F301K8U6 (UFQFPN32 package) I connected the exposed pad area with the ground but currently I am not sure if its correct. There is not a word about what to do with it in the htt...
