I am having issues when writing a buffer that is declared in the external buffer to an SD card. When I tried to download a bulk file (1.5MB), write failure (f_write returns FR_DISK_ERR) would happen at least once during the download process, but if I...
HI I m using H743 Nucleo, to write a RTOS program with 2 tasks which gonna access to the same memory location concurrently.. can anyone advise which RTOS method to use ? Tasks ? Semaphore? Message Queue?
I'm a software developer and love electronics, specifically making metal detectors. I'm trying to develop a new Pulse Induction metal detector and I'm using this development board (STM32F407VET6).Although I'm a software developer, I work with high le...
I am really confused about the meaning of the VirtAddVarTab that is filled with number from 1 to NB_OF_VAR. My understanding is that is used to copy from one page to the other when the first is full. Anyway I had to save a structure to EEPROM and rel...
Hello,For my project Im checking on a data request by using DMA and UART Idle interrupt. After a few minutes my while loop just stops executing. The code keeps executing the USART1_IRQHandler and doesn't return to the main code anymore. If Im not usi...
I need sample code for FOTA update through UART please as soon as possible share
Hi, while using the SVD (Version 1.8 - but in the 1.9 zip this file still states 1.8) for the H743 I noticed some errors and have patched them for my code generation. Some of them caused me trouble for hours until I noticed that the SVD and the RM di...
@STTwo-32, I also noticed issues in the EXTI.Sample:stm32h7s7xx.h, &(EXTI->PR1) == 0x58000088STM32H7S.svd, &(EXTI->PR1) == 0x58000020When should we expect the upcoming release (in 2 month?)?Also, are there public script which validate that stm32*.h...
The problem only happens when a constant stream of data is being send to the UART. When I update my firmware sometimes DMA won't work. It is hard to debug when it only happens when updating and not every time. This post is exactly the same issue as m...
Hi I am trying to run freeRTOS on STM32f407 so I want to know at what frequency my clock will run let me share you my clocking diagram too. another doubt how to enable SysTick_Handler. other external interrupt I have enabled like this NVIC_SetPrior...
