Posted on June 14, 2012 at 07:10Hi there, Can someone explain what is the role of the mpu? From what i understand, it is only for OS purposes, meaning that whatever the mpu configuration is made at boot time, can be changed again by the user from a...
Posted on May 25, 2012 at 15:58Hi,I am new to this forum and I am programming the STM32L-Discovery using Crossworks.I am currently trying to do something which I believe should be relatively simple. e.g when I touch the 1st quarter of the slider - d...
Posted on June 13, 2012 at 17:12Hello everyone, I'm working on STM32F207VE Kit . Has anyone ever set the frequency to exceed the limit for APB2 (greater than 60 Mhz).Yesterday, I had set up freqency for APB2 is 120Mhz (by my mistake). To day, the pe...
Posted on January 27, 2012 at 09:48Update:Ok quick update I have now edited my code to only use DMA with the ADC and software trigger (DAC_SoftwareTriggerCmd) the DAC and it works fine. Therefore it seems to be a DMA issue. The new implementation I ...
Posted on June 10, 2012 at 19:07Hi there, I would like to know if there is a way to protect your binary image in a stm32f device (with mpu). With protection i mean that i would like to secure the binary image that runs on the device from been stolen...

Posted on June 12, 2012 at 13:21Hi, I am new to the STM32 micro-controller. I am using STM32F207 board to communicate with another custom micro-controller board. The communication is basically sending commands and receiving response using USART6 ISR...
Posted on June 11, 2012 at 20:03Looking at the STM3210B evaluation board schematic, the 8Mhz crystal has a 1M resistor in parallel across the crystal. Looking at the STM3210E evaluation board schematic, the 8Mhz crystal has a 390 resistor between ...
Posted on June 09, 2012 at 15:13I have a STN LCD (that have only 24 segment and 1 common)-at 3.3 volt. Can I use stm32f103 to drive it directly?(by 100Hz toggling segments with respect to common pin) Is there any note for this method? Is there any ...
Posted on June 11, 2012 at 22:34I have designed a brushless servo motor driver with F103 I use Timer 4 in encoder mode and connect motor encoder to CH1 and CH2 at the same time for changing UVW phases I compare timer value with 24 constant numbers ...
