I wrote some software that reliably measures the number of memory cycles required to retrieve 16 and 32-bit operands from the Cortex-M4 memory. When a 16-bit operand fits within a 32-bit physical word, I would have expected that only a single memory ...
hey thereI try to receive some characters using UART and here is the confighuart1.Instance = USART1; huart1.Init.BaudRate = 4800; huart1.Init.WordLength = UART_WORDLENGTH_8B; huart1.Init.StopBits = UART_STOPBITS_1; huart1.Init.Parity = UA...
I found that STM32F4 timers might count incorrectly until first update event if using a prescaler. I can consistently reproduce this with multiple general purpose timers in a least two different STM32F4 variants, a STMF32407 and a STM32F429.Is this a...
Hello,I try that when my OUTPUT compare is triggered, it triggers a function.As for the PeriodElapsedCallback method, when the timer is in overflow, it creates an interuption and the PeriodElapsedCallback function is called. Is there a function doing...
It stops at comparing values written into the flash. At the begginig some data are copying well, but then it doesn't match and return FLASHIF_WRITINGCTRL_ERROR. It always stops at the same position, but when I change size of stack it becomes differ...
Short version: I am working with the STM32F446 family and I use TIM1 as 4 independent timers:typedef enum { TIM1_CHANNEL_1 = 0, TIM1_CHANNEL_2 = 1, TIM1_CHANNEL_3 = 2, TIM1_CHANNEL_4 = 3, } timerAndChannelSelector_e; void scheduleTi...
Hello, I would like to change TIM2 to TIM5 but my code didn't work after I changed that. Could someone help me please? Thanks a lot Here is the code #include "stm32f4xx.h" /* PA0 - TIM2_CH1_ETR/ TIM5_CH1/ TIM8_ETR/ USER BUTTON PA1 - TIM5_CH2/ TIMM2_C...
STM32CubeMX (STM32Cube_FW_F0_V1.11.2) allows option for One Pulse Mode for TIM14. Does TIM14 actually support OPM on STM32F031G6U? In Reference Manual (RM0091 rev 9), TIM14_CR1 does not have bit 3 OPM. Is mistake in Reference Manual or in STM32CubeMX...
STM32G0 supports writing double word to flash. If I need to write a word or half word, how to do that? Any examples? I am currently migrating code from F series to G series.
I had installed required drivers for STM32F103C in my PC and also I had installed necessary packages in keil IDE and Arduino IDE. I am not able find out the problem.I am using ST-Link V2 i have made a proper connection with STM32F103c board.Below I h...
