Posted on August 15, 2014 at 18:56Dear friends. Show me please my mistake. When I debug the following program I even cannot get to ISR... I stay in infinite loop... Thanks! void EXTI0_IRQHandler (void); int main(void) { /*!< At this stage the micr...
Posted on August 19, 2014 at 01:01Hi, I am not able to clear a timer update flag while the timer is enabled. I am initializing a timer and the behavior is the following: .... TIM_TimeBaseInit(TIM4, &TIM_TimeBaseStructure); TIM4->SR = (ui...
Posted on August 13, 2014 at 00:06Hello.I'm following the procedure in AN2604 and trying to use an internal timer to measure the rtc frequency by looping back the rtc into a timer pin, in my case PA8 (Timer 1 channel 1), and then using PWM input cap...
Posted on August 18, 2014 at 18:11 Hi, I want to communicate with an i2c eeprom, I am able to send the first data but not the second. it seems that the buffer is full or there is another error somewere. Does anyone have an idea? #inclu...
Posted on August 18, 2014 at 16:20Hello,I'm discovering the STM32F407 with an STM32F4Discovery, in the past, I worked with a PIC32, and I see that there is many differences between those two microcontrollers.I want to understand how the UART periphe...
Posted on August 18, 2014 at 16:17So this maybe a very stupid and noob question: Are the library functions of stm32f4 and stm32f3 the same? I have been working on stm32f4 for quiet a while and had written a large amount of code for a certain project...
Posted on August 18, 2014 at 13:33Hello,How to find out what are the frequencies possible on I2C,SPI,UART buses of STM32F051xx? How to calculate the cross talk coefficient of these buses if the tracks corresponding to them are .2mm wide and are .3mm...
Posted on July 23, 2012 at 19:53I got 2 new STM32F4 Discovery boards and both are not being recognized by STLINK utility. Here some of the observations. I compared the behavior to STM32F1 discovery board. (It is Windows 7 PC).1) Plug in STM32F1 boar...
Posted on August 17, 2014 at 15:34 Hello,I'm currently quiet frustratedI'm trying to set up with the RTC wakeUp register an interrupt of 128Hz. For the RTC the LSI is used (I know not very precisely but for current testing propuse its enough)here i...
Posted on August 13, 2014 at 10:55Hi, I am unable to run the example STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\FSMC\SRAM_DataMemory on my STM3210E-EVAL Board. Although I have made the following settings Project->Options ...
