Posted on December 18, 2014 at 17:00When debugging some code that uses DMA to receive data from an uart i noticed that if for some reason an overrun error happen, it's not taken into account, and that prevents the DMA transfer complete interrupt to ...
Posted on January 20, 2016 at 16:53Hi all, How can I check if interrupts are enabled (i.e. find out if __enable_irq() or __disable_irq() were previously called)? I use STM32L4 (M4) Thank you #interrupts #arm-cortex-m4
Posted on January 20, 2016 at 14:09My application requires to input capture a pulse to trigger TIM1 & TIM15. The trigger pulse is present on both input capture pins and channels. Both timers are to turn on at the same time but have different counts ...
Posted on December 25, 2015 at 21:32 Hello! I'm porting my project from std periph to HAL using Cube to tune HAL. I have a trouble with sound playback on stm32f103ret6 via DAC channel 1 with DMA triggered by TIM6. DMA works well that I can s...
Posted on November 11, 2015 at 10:45 Hello, I set up a uart project from CubeMx for STM32F0308 Disco, Basically I want to send ''test'' strings every 3 seconds via DMA however after I only get a single ''test'' in terminal. HAL_U...
Posted on January 18, 2016 at 15:30 Guys, Which API should I use for reading the value of SPI data register (SPI_DR) ? How can I differentiate between data from SPI1 and SPI2 ? I tried to port from AVR to STM32CubeMX....
Posted on January 19, 2016 at 08:07I am trying to generate the PWM from STM32F4 micrcontroller. The PWM output was done but it is 0-3.3V range. May I possible to configure the PWM voltage range (0-5V) if so, can someone guide me the way to proceed i...
Posted on January 15, 2016 at 08:33I have been using ST-Link to flash the firmware of STM32L151Cx. Now, I would like to add the feature of flashing the uC using USB. I have checked on the datasheet and knowing that if I set BOOT0 = 1 and BOOT1 = 0 a...

Posted on January 20, 2016 at 10:38 Hi, i try to create a movie by using a file which is not available in addressable RAM or ROM. The file is stored on USB. I use this funktion: int MS_GetData(void * p, const U8 ** ppData, unsigned NumBytesReq, U32...
