Posted on January 04, 2013 at 10:12Hello all, I am using STM32F2.Pll as clock source which uses HSE as PLL clock source. I want to set my System core clock to 24Mhz and i have done. And I read one of the comment in stm32f2xx_rcc.c which says ''Syst...
Posted on January 03, 2013 at 08:49We have an STM32373C-EVAL board and we've been trying out the firmware demo samples. One thing I've noticed is that if I enable the USE_FULL_ASSERT, most samples will crash. (Well, not crash but get caught in the a...
Posted on January 21, 2013 at 11:30Hello, I newly started working with the stm32f0 discovery board on Coocox. I have downloaded the examples from ST but it doesnt compile. It seems that the linker doesnt find the definition of some types, even if I ...

Posted on January 16, 2013 at 10:06Hi, our institute is currently using STM32F103 devices in a distributed control system. However we are evaluating a switch-over to STM32F40x devices for the sake of its FPU and higher clock speed at comparable cur...
Posted on January 21, 2013 at 03:48Hi Great people of STM32, I would like to ask if it is possible to work with lan directly with the MCU or I need to buy interface shields that communicate via spi? but i have seen that stm32 has dedicated pins for ...
Posted on January 21, 2013 at 00:35Hi guys, I have this question, /* GPIOA Periph clock enable */ RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE); /* Configure PA0 .. PA7 in output pushpull mode */ GPIO_InitStructure.GPIO_Pin = GPIO_Pin_...
Posted on January 11, 2013 at 02:121-i'm confused in datasheet i see 4x64mb per bank . it's means maximum of each nand flash is 64mbyte . 2- in the AN2790 Application note about lcd with fsmc. read from NAND Flash 11 fps read fron sd card 12fps...
Posted on January 20, 2013 at 18:12I need to be able to store ADC sample on a SD card. the sample rate is 200KHz.Since the buffer size register is limited to a maximum value of 0xffff I decided to use the DMA in a dual buffer mode and ADC in Continu...
Posted on January 20, 2013 at 08:38Hi, I want to measure the preformance of my program,by measuring the execution time of various functions ,as the atollic toolchain dont have functions like : clock_gettime ,that is somewhat accurate to the milli se...
