Posted on November 26, 2012 at 16:14Hello!I try to receive data by I2S3 in slave mode.First of all I tried to program I2S controller and received data by program polling: while(1){ while( (SPI3->SR & SPI_I2S_FLAG_RXNE) == 0 ); SPDiffRxBuffer[T...
Posted on November 22, 2012 at 12:37Hi, I am trying to configure my MCBSTM32EXL board to read from an external temperature sensor. I think I have most the code sorted, including reading from the ADC. However, my knowledge of electronics is weak and ...
Posted on November 26, 2012 at 14:05I am using a STM32F4 FSMC to address external 16-bit SRAM on a custom board. Everything is OK. I want to connect an external FPGA and I'm not so clear about the actual addressing. Please correct me if I'm being s...
Posted on November 08, 2012 at 10:51Dear All, After playing around with my new STM32F0Discovery board, it looks like that it has entered a kind of reset state. It continuously generates NRST signals with an interval of 400ms, even when i have clear ...
Posted on November 25, 2012 at 11:22 I'm sorry, but I do not quite 5v tolerant ports for STM32. I do not unterstand concept '' Total injected current (sum of all I/O and control pin)'' Example STM32F0 and on 8 5V tolerant I/O connected L...
Posted on November 25, 2012 at 09:17Hi, We used STM32F103Z on one our boards, using the programming via UART1 with Flashloader Demo application. Everything was fine till the moment, when we decided to replace it with STM32F407. Of course the package...
Posted on November 23, 2012 at 11:03 Hi fellow forum mates, I am a student working on a new project using stm32f4 eval board. My task is to measure the frequency from 3 different sources ranging from 1000hz to 725khz. I have been trying f...
Posted on November 24, 2012 at 15:09Hi, please have a look at the following code (STM32F407):volatile long long vllPosition; void TIM1_UP_TIM10_IRQHandler(void){ ... do interrupt stuff ... vllPosition ++; ... do interrupt stuff ... } int main( voi...
Posted on November 18, 2012 at 12:03 Hey everyone, I'm working on the STM32F4DISCOVERY with CoIDE 1.6.0 in C++. I have an interrupt on TIMER4 overflow, and so I put the interrupt service routine (void TIM4_IRQHandler(void) {}) in the main.cpp....
Posted on November 23, 2012 at 12:12HI, I'm I right to assume that in 100pin devices FSMC can be used only in multiplexed mode as Address bus is not available on this chips? Or one should drive Address lines in FW. So that A0 used as RS signal for ...
