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 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...
Posted on May 08, 2012 at 12:08For my current project we are using a development board of powerAVR. It has a 3.5� TFT touchpanel with resolution 320x240, using 16bit FSMC bus for communication. But I need to have implement it on a 5.7� TFT with ...
Posted on May 09, 2012 at 14:37Hi all,I need some information regarding the STM32F207 IOs output voltage levels... in fact according to the datasheet (Table 44) the VOH Min is:- 2.4 V for CMOS ports- VDD - 0,4 for TTL port.However I know that all ST...
Posted on May 08, 2012 at 10:13 hello everyone! Help me, please, to find where is a bug in my programm for CAN slave. I have two boards. One is evaluation sk-mstm32f It sends requests. And the other board is my own board on stm32f103, which ...
