Posted on May 11, 2012 at 16:28Hello, I have worked with STM32 on several demo boards. Now I want to start my own PCB board with STM32 microcontroller. I like the free EDA tool of KiCad, which is available on both Windows and Linux. However, I ...
Posted on May 06, 2012 at 19:45 Hi all, I just wanted to share the surprise that I had today when, in order to have the USB CDC example virtualizing USART2 at 115200,8O1 on a STM32F102RB clocked with a 16MHz oscillator I had to configure ...
Posted on May 07, 2012 at 18:42Hi, I have a problem, because there are sensors signals a lot (at handler). The signals arrive at the same time, and then, sometimes, the counters don't stay the same each others, but I am simulating at the same signal...
Posted on May 11, 2012 at 07:55I have purchased the STM32F407-Discovery board. Earlier I had been working on the STM32 20-21-45-46 G-EVAL board that had STM32F207 series microcontroller. I had successfully implement own application on STM32F207 seri...
Posted on May 09, 2012 at 17:18hi, i'm trying ton increment a timer in timing mode at each rising of a signal which arrive on an other pin here my code : RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2,ENABLE); RCC_APB1PeriphClockCmd(RCC_APB1Pe...
Posted on May 11, 2012 at 03:42Hi, I looked thru' the tftpserver.c code, and noticed that there are possibilites of memory leak in process_tftp_request() if efs_init() or ls_openDir() fails, ie, upcb is not released. Can anyone confirm that? Thanks...
Posted on May 10, 2012 at 17:07Hi, I am using STM32F105RB and I have a problem with an I2S master receive connection, using SPI2. I have configured SPI2 in I2S master Receiver mode, and enabled a SPI2 receive interrupt but immediately after SPI2 ini...
Posted on May 10, 2012 at 15:19Hello, I am evaluating the SMT32F407 and I am wondering how it is possible to execute code from flash with 0-wait state. In the datasheet on page 67 it is described that the number of wait states it 5 at the maximum C...
Posted on May 10, 2012 at 11:17I have an interesting problem I hope someone can explain.I was trying to modify the PWM_Input example from the StdPeriph examples to work with TIM5 so I could get a longer range. I have tried to use both TIM5_CH2 (PA1)...
Posted on May 10, 2012 at 14:12i am on the stm32l discovery and i send a square wave on the pin PA1 but it's like i don't receive it, i'm trying to read it with the function GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_1) but it desn't work !! int main(voi...
