Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I have a USB HID product based on the STM32F205. We've built thousands of them. However, recent builds have shown about a 5% failure rate where the device fails to enumerate (some of this 5% might fail 50% of the time when power cycling, some 90%+). ...
I'm debugging a legacy application on an STM32F407 that uses the std peripheral libraries and LwIP 1.4.1, and except on rare occasions, hardware IPv4 checksums don't work; they all get sent out as zeroes. When I disable hardware checksums in lwipopts...
Before programming when i connect the board with UART bootloader:After clicking on download option, it is showing following errors:
There is very little information on the internet, let alone any example that I could look at. My problem is that freeing a semaphore does not trigger an interrupt. I need this feature to allow one core to notify the other in case a certain condition ...
I decided to try to use the __HAL_ADC_ENABLE_IT() macro. UM2319 page 95/2202 Rev 2It says the first argument is the ADC handle. ADC_HandleTypeDef hadc1; is the handle. This macro wants the ADC handle pointer which is &hadc1 not hadc1. Looks like the...
Hello, I made a board with STM32G030J6 in SO8 package. There is not much pins so I need to use UART bootloader. Problem is that BOOT0 is on the same pin as USART.I have USB-3V3_UART so I connect BOOT0 to 3V3 first, start the power supply, then I reco...
I am getting desperate trying to solve this issue.When I add some content to HAL_TIM_PeriodElapsedCallback the main loop gets frozen but still continue receiving call on HAL_TIM_PeriodElapsedCallback. Could somebody help me out with this? I have been...
I bought stm32h745i-disco. Im starting with development of stm32. �?´m familiar with pic32 development but I need use dsp functions of stm32h7. I can wotk with adc, timers .. and I learn how to use CubeMX for development. But now I have problem to us...
Hello! I'm using a STM32F407VET6 to receive data from USART1 and USART2 with DMA and send it by USB, but I can only receive and send data from USART1.This is my callback functionvoid HAL_UARTEx_RxEventCallback(UART_HandleTypeDef *huart, uint16_t Size...
