MCU : STM32F411CEU6 Hello everyone. I have an application in which I want to get image end address from linker. Here is a full context of what I want to do, I have a struct living in start of my image, which basically tells the bootloader usefull inf...
I am trying to make a USB HID self powered device with STM32G473 without VBUS. I understand that I will require VBUS sensing on reconnection but even when I have already connected the USB then power up my device I only get reset request from host aft...
STM32F103 as Interrupt driven I2C slave . in the address callback Master READif (dir == I2C_DIRECTION_RECEIVE) // 0 { data[0] = 0x55; data[1] = 0xAA; HAL_I2C_Slave_Seq_Transmit_IT(hi2c, &data[0], 2, I2C_LAST_FRAME);}On the wire (see pi...
I'm working on a project where I use the STM32U5A9 microcontroller to control the W25Q128JV flash memory. I wrote a library to interact with this flash memory, but unfortunately I can't get it set up correctly.The problem is that commands are sent in...
IMHO in the file "stm32f3xx_hal_def.h" the section "Exported types" should be moved in front off section "Includes", because some of the types are used in the included files, but "stm32f3xx_hal_def.h" will not be reentered. It produces error like thi...
Since upgrading from STM32Cube MCU Package for STM32L4 from 1.17.1 to 1.17.2 (or 1.18.0), when disabling the PLL, HAL_RCC_OscConfig() will fail with HAL_TIMEOUT.I reconfigure the oscillators and PLL to run at 4 different speeds, depending on mode: 2M...
This is a long one, so sit tight around the campfire, and let me tell you the tale of The Futility of EPENA.Several days ago, I began to implement a Mass Storage interface for my own USB stack, equipped with a Bulk IN and OUT endpoint. The first thin...
Hello, I wanted to share an issue I found with enabling the oversampler for ADC using HAL. I was having issues result not being bit shifted. Further investigation I found that the HAL driver version 1.11 did not write the OVSS bits correctly. Here is...
stm32h7xx_hal_uart.c is missing a prompt to enable usart interrupt in the DMA configuration instructions.Other comments have this sentence:(+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle(used for last byte sending c...
I am trying to send a message through UART based on Timer 6 interrupt on STM32L432KC microprocessor. The prescaler is set to 39999 and the auto reload is set to 19999 to get an interrupt every 10 seconds. When i upload the code, I get the first inter...
