Posted on April 15, 2014 at 15:23 I have a snippet which works, it blinks blue LED on stm32f4discovery: void TIM6_DAC_IRQHandler() { if (TIM6->SR) GPIOD->ODR ^= (1 << 15 ); // Toggle D15 TIM6->SR &= ~1; // Interrupt has been handled ...
Posted on April 15, 2014 at 05:04 Hey all, I'm working on a project where I have to process an audio signal in a few different ways. However, I have never done anything of the sort. I have been reading up into how to implement basics such...
Posted on April 15, 2014 at 19:14I just purchased the STM32F439I-EVAL2. The board didn't come with any BSP or code that I can build in IAR. I'm guessing I need to use STM32CubeMX to configure the Bsp and setup the pinouts used on the board. Unfortun...

Posted on April 11, 2014 at 08:21I've got STM32F407VE controller that works at 168 MHz. I need to get a 8 MHz clock frequency from it and I guessed to use a timer in PWM mode, but they all have a 42 MHz or 84 MHz clocks and so I can't use approriate...
Posted on April 14, 2014 at 22:17Hi all, just a simple question hopefully,In the peripheral example for configuring TIM3 for PWM output, calculations for working out PSC and ARR values are given, comments supposing to explain them.The bit thats conf...
Posted on April 14, 2014 at 19:51Hi, I am trying to create a chronometer runs in parallel with my main program. For my part I have created a delay function that works perfectly. And I tried to make the stopwatch with sysTick but its does not work. ...
Posted on April 14, 2014 at 10:56Hello everybody , I have a firmware which runs whose offset adress is 0x9000 and on stm32f105RC (256 KB Flash, 64K Ram). It is a iap sw that runs on stm32f205 I am trying it to run on stm32f105.NVIC_SetVectorTable(NV...
Posted on April 15, 2014 at 16:26I'm using TIM1 for a 6-step motor control on a STM32F2xx. According of the table 4 in DM0004234 application note, I update OCxE and OCxNE at each commutation, to select a new step. When OCxE = 0 and OCxNE = 0, the ou...
Posted on April 15, 2014 at 11:09Using two USARTs running at 115200 baud on a STM32F2, one to communicate with a radio module and one for serial from a PC. The clock speed is 120MHz.When receiving data from both USARTs simultaneously overrun errors ...
