Hello,I am new to STM32 and I am trying to write into FLASH memory using some reference code I found in internet. Here is my write function:uint32_t Flash_Write_Data (uint32_t StartPageAddress, uint32_t *Data, uint16_t numberofwords){ static FLASH_Er...
Im trying to communicate between nucleof446re board with other processor board using UART.Communication works fine when I connect my nucleo board with USB power supply but when I connect nucleo with external 3.3V or 5V supply the communication does n...
Hello I have a Nucleo-H723ZG and I'm trying to build a custom bootloader with CMSIS v2 that need a TCP connection. Since it needs to receive 1KB of data through TCP I've made the receive array long 1024 bytes, but this size crashes the whole LWIP mak...
Hi,I want to compare a couple of different ways to implement the same functionality in an ISR to see which one leads to the smallest/fastest code. Is there a way - after compiling but without running a debug session - to see the disassembly code afte...
Hello, all. I am currently trying to program a black pill board to print out the output from a sound sensor, for which I use the Arduino IDE 2.3.2. Used components:- STM32F411CEU6 black pill- KY-037 sound sensorCurrent connections:- the "G" pin from ...
Hi,I am using a STM32L452RET6 (without any RTOS) and I would like to use the same timer for both:- drive a sounder on PWM at 4KHz (but ideally also other changing frequencies above and below 1ms time period so it can make more elaborate sounds which)...
Hi,during implementation of a bootloader I have encountered a problem.I'm using stm32 standard peripheral library.During writing to flash, for example at address: 0x0800C000 or 0x08010000 when the 18th line: FLASH_Status FLASH_ProgramWord(uint32_t Ad...
Hi everyone,I have written class that handles U(S)ART communication on top of HAL. In my application I have several objects of that class, e.g. one for USART2, another for LPUART1,...Currently, I have my own way of registering callbacks: I have stati...
Hi all, i decided to write a simple program on my stm32 board (B-L475E-IOT01A), here are some of the setting of my peripheral: i read input data from channel 2 sampling data on rising edge The clock frequency at which the microphone is outputting P...
Hello everyone, thanks for your help.I have a problem regarding the states of inputs that were set exactly the same way.After powering all 10 inputs simultaneously, inputs IN4, IN5, IN6 and IN7 are not in SET, the others are in SET. Relevant data:Usi...
