STM32L496 USART1 RX crash @ 1.8V IO
Posted on September 12, 2017 at 10:50Dear community.I have a very interesting issue - I am working on STM32L496 Nucleo board and working with USART1. Everything works fine there with USART1 receive/transmitting in INT mode. (Nucleo runs 3.3v with ...
What happens if I use the same priority and sub-priority in multiple NVIC?
Posted on September 13, 2017 at 04:41Hi.Now I'm trying to implement USART interrupt mode.But I'm wondering if I use the same priority and sub-priority in multiple NVIC, what happens?For example,If I use as the below,NVIC_InitStructure.NVIC_IRQChanne...
SDIO (SDMMC) and FatFS with CubeMX
Posted on May 12, 2016 at 13:55Hello! I try to use the SDMMC1 interface together with FatFS. Initialization is created with CubeMX. My init is something like this: ... MX_LTDC_Init(); MX_SDMMC1_SD_Init(); MX_FATFS_Init(); ... Then I try to use the S...
DMA delay caused by Interrupts?
Posted on September 04, 2017 at 12:33 On my STM32F411RE I send data to my SPI2 peripheral port using DMA and it works fine, but the moment I enable any kind of interrupts for the NVIC it completely scrambles up my stream of DMA data on my SPI2 -...
