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 09, 2012 at 18:12Hello, I' needed a solution for production programming, knwoing that I need to program a unique serial number (not sequential) generated from my IT system. Basically I had 2 options : - Get an autonomous SEGGER Flasher...
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 ...
Posted on May 10, 2012 at 01:17This function: ITStatus DMA_GetITStatus(DMA_Stream_TypeDef* DMAy_Streamx, uint32_t DMA_IT);Does not correctly detect the interrupt status on this chip. The interrupt status can be correctly discovered by the simple ...
Posted on May 09, 2012 at 06:29Working on our own hardware with an external mux. Want to switch the mux on the interrupt, so I need the interrupt to happen. So far I see no interrupt. Configured as ADC3 so the default IRQ is either of ADC_IRQHan...
