Posted on February 03, 2018 at 07:45I want to calculate CRC for large file, the large file have been added the CRC value in the end of the whole .bin file(Get this CRC data via IAR tool). I read the file and calculate CRC of it in part(HAL_CRC_Calcu...

Hal stm32f103 and dds problem

i have problem with data ud and clk signals out to dds.its not a steady stream to dds.in the oscilloscope the data,clk ud signals are not stable.the signal are moving and jumping around so the dds of course gives weird and wrong freq.i tried intern...

Interrupt gets executed but the CPU stays in WFI

stm32f407i code in RTEMS, system sleep function will call __wfi , i can not wake up from sleep by pressing keyrtems_isr EINT95_handler(rtems_vector_number vector) { if(EXIT_PR & 0x200) { printk("exit 9 hap\n"); int pin = STM...

IWDG trapping

Hello,I activated the IWDG on a STM32L431 device and a watchdog occurs. How could I trap it to find the issue?This watchdog resets the device so I do not know how to find the stack values when this watchdog occurred.Is there a way to send this IRQ to...

Timer 1 as capture input for frequency measurement, not getting Capture interrupt

I want to use Timer 1 as capture input for frequency measurement: ( STM32F207ZG)void STMF2Timer_Configure( void){ TIM_TimeBaseInitTypeDef sTIM_TimeBaseInitStruct; TIM_ICInitTypeDef sTIM_ICInitTypeDef; NVIC_InitTypeDef NVIC_InitStructure; ...

Using a STM32F4 MCU: Which is the right way to manage the TX and RX ?

Hi all,I'm using a STM32F4 MCUI'm having much problem handling ISR and/or DMA with UART TX/RXCould anyone tell me which is the right way to manage the TX and RX ?In case of ISR i can only TX correctly , but when i try to RX ... i can receive only 4 ...
