I want to try gdbserver and openOCD on CLI so as to compile and debug STM32 MCU Firmwares via CLI and to get an understanding of their work. But not able to get enough resources on the net for their installation as I am windows user and resources ava...
Hi, I want to store 8 bits of data coming from my Modbus in a different variables in the form of 1's and 0's using stm32f103.I have done code like , the bits i have sent is 101101101 sent by Modbus is storing in my holding register [1] in the fo...
So,LPUART can not use LSE to configure BaudRate 9600?
General idea:I'm trying to write the I2C as slave on a L476. The master might need to change a bunch of registers at the same time, so instead of sending n separate commands I want to receive one long command and the prepare the response to be sent b...
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...
