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...
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...
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...
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...
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; ...
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 ...
Hello Everyone,I have dealing with STM32F407 I2C peripheral in order to implement Non-blocking communication.I have made many trials but I2C1 event and error interrupts never occur. I checked the SB bits during the debug mode it becomes 1,the other r...
I've turned on VREFBUFF. Datasheet claims that factory trim values should be automaticaly loaded into VREFBUF->CCR. Thru debug i can see that CCR=00000 (no relevant value loaded). And measurments at VREF+ confirm that.REF 2.5 = 2.431VREF 2.048 = 1.99...
I've been developing my own I2C interface. When the BTF is set, I issue STOP. However, the interrupt routine is repeatedly called until the STOP is generated..In document it says that BTF is cleared by hardware after a start or stop condition in tran...
Sorry guys i am just starting with MCUs generally , i am now playing with NUCLEO boards , ran a couple of programs like LED , External interrupt . But came across the expansion board and in the datasheet they have given it uses DFSDM , but i cannot...
