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...
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...
I have a STM32H573I-DK discovery board, purchased for the purpose of getting to grips with Azure IoT.It appears however that the example does not run properly.Compiles and links OK, and I am using the Wireless plug in board as supplied, but it gets s...
I have STM32F407G-DISC board.Hello Everyone,Problem: I am working with a instrument where we frequently get the problem of frequency drop out, i.e. suddenly frequency signal goes missing i.e. goes to zero, this cause the loss in data as shown in the ...
Hi,I am using the STM32F407VG and PmodI2S2 to transfer 24-bit audio. For the most part I have followed this tutorial. So far everything works and I have audio throughput and the ability to manipulate it.In order to understand better the underlying co...
