Posted on November 01, 2014 at 10:46I've noticed that the output of the clkout pin is very near the frequency I would expect when a external crystal is used as the pll source, but fluctuates a little as the CPU performs gpio operations. When I confi...
Posted on November 01, 2014 at 18:32Hi Guys, I have written a handler for an external IR beeing executed on a STM32F107 controller. It looks like this: void EXTI9_5_IRQHandler(void) { //TEST GPIOE->BSRR = GPIO_Pin_9; //set PE9 works fin...

Posted on October 31, 2014 at 12:11I'm at wits end trying to figure out why exactly I can't transmit on UART4 or USART3.The RX works, and i can receive data, however the TX pin is not working at all. Below is my configure code for UART4.void init_us...
Posted on October 31, 2014 at 13:53 Hi all. I'm working on a project on an STM32L151CBT6 uC, and getting occasional, unexplained error bits WRPERR and SIZERRset in the flash controller. I set up the flash error interrupt to use the highes...
Posted on October 31, 2014 at 14:09 I use STM32F030F4 and want to use SRam-parity-checking. The reference manual hints: ''When enabling the RAM parity check, it is advised to initialize by software the whole RAM memory at the beginni...

Posted on October 29, 2014 at 01:37Hello.I am new in ARM development and I am trying CooCox. I want to buy a debugger and I would to know if I will be able to use ST-LINK/V2 with CooCox.Thanks in advance. #debug-stm32-using-st-link/v2
Posted on October 31, 2014 at 10:41Hello, I want to make a timer for my software (call a call back when time is finish). I need to understand the clock source for the timer. I choose to work with TIM7 for that (basic timer). As I see, using RCC_GetC...
Posted on October 31, 2014 at 14:42Dear all, for my application on an STM32F205x the ADC dual slow interleaved mode is the most suitable mode for sampling an analogue signal. In AN3116 both the fast and slow interleaved modes are described. Addition...
