Hi all,I want to use timer 2 to trigger ADC function (ADC3) on STM32H743ZI2 platform. After DMA & timer starting, I stuck in HAL_ADC_IRQHandler(). /* Multimode not set or feature not available or ADC independent */ if ((hadc->Instance...
i would like know the cause of reset during the power on stage for may application.i would like to differentiate if its power on reset/NVIC reset/WDG reset or any other cause?
I am developing on the STM32H7B3i-DK board using Keil MDK + STMCubeMx for creating the project.For some bizarre reason that I can't explain, I can no longer do debugging on my dev board after been blocked for a few days by an issues that I had with "...
I see that H723 and variants are coming.Any plan for Nucleo or discovery kit for these?
HI,I'm trying use SDIO interface on STM32F469I-Discovery board and I'm always getting FR_DISK_ERR for the command "f_open(&myfile,myPath,FA_CREATE_ALWAYS|FA_WRITE)" Same problem is observed with 1-bit and 4-bit SDIO mode. I have enabled "Use DMA te...
HelloI have the problem with USART baud rate in STM32F09x. I want to use baud rate: 9600, 19200, 38400, 57600, 115200bps with data length - 8 bits, parity and one stop bit. I can connect to the device at all speeds except 19200. Microcontroller uses ...
I am using STM32L072hence referring to reference manual RM0376Page . 280 Table.53 suggests that priority can be from 0 till 38but when try HAL_NVIC_SetPriority(IRQn_Type IRQn, uint32_t PreemptPriority, uint32_t SubPriority)as per help above that f...
There are two points of confusions.1. VREFINT_CAL is a 12-bit precision valueUnlike predecessor of H7 family (H743, H7A3, etc.), the VREFINT_CAL value stored in VREFINT_CAL_ADDR is a 12-bit precision value stored in a 16-bit (8-bit x 2) location.For ...
I'm currently using the stm32f413zh, and face perhaps a general problem where I'd like to send four CAN messages right after each other. If we refer to the image below, I have four "addtxCAN" commands below and only able to see the first three. When ...
I am trying to get the temp of the internal temp sensor.. I tested on both MB1367 demo board and my own board.I use jumper to connect JP8 pin2 and pin 3 to get Vref as 3.3V. I attached the cubmx and main file of my simple code. The issue is I always...
