Posted on May 31, 2012 at 18:07Hi,I would try to program a custom made board, with stm32l151 micro onboard, by usingone stm32F4 discovery board.Now, before I burn something, discovery board is powered from USB 5V; my custom madeboard is powered at 2...
Posted on October 15, 2011 at 10:03I could not simulate my code written for STM32F205ZE using keil 4.2V.Following is error code it is showing, when I start debug session.*** error 65: access violation at 0x0000000C : no 'read' permissionIf I try to ...
Posted on May 30, 2012 at 10:45I have designed a PCB that has an http://www.st.com/internet/mcu/product/250189.jsp microcontroller. It kind of works, but the micro has a weird power-on/startup problem. Basically, when the power is applied the micro ...

Posted on May 28, 2012 at 12:29Hi, I see on the an3216 ''getting started with the stm32l hardware development'' that there is a strange 10uF (ceramic?? non polarized ??) connected to the vdd. Instead,if I see that on the stm32l discovery schematic t...
Posted on May 28, 2012 at 18:51Why should the App.h file with : /// PORTA[0..15] = Available : RCC_AHB1PeriphClockCmd( RCC_AHB1Periph_GPIOA , ENABLE); GPIO_InitStructure.GPIO_Pin = (GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_2 | GPIO_Pin_3 | GPIO_Pin...
Posted on May 29, 2012 at 11:52hi, I am using stm3210c-eval and Ride7. in my project i need to write and read from a micro sd card (file.txt). can you help me? thanks .
Posted on May 29, 2012 at 11:13Are STM32F2 family processors capable of multimedia processing ?? for example : can they be used to capture videos and track objects or other camera features real time with a high quality image sensor (5MP and 720p @ 6...
Posted on May 28, 2012 at 07:28How should multiple interrupt flags be handled in the timer ISRs? 1. Handle all flags at the same time? 2. Handle a single flag? My code originally did #2, but I found sometimes I would get into a state where an interr...
Posted on May 28, 2012 at 07:21I'm actually hunting down a weird case where sometimes the timer counter matches the CCRx register but I never see the CCxIF flag set. This seems to occur when the compare occurs when I'm in that timer's ISR handling a...
