Hi We are working on STM32H503 MCU which has ARM Cortex 33. In datasheet it is provided that 12 cycles or instruction to enter into an interrupt function. Configured system clock as 250MHz, with that we could reach an interrupt function within...
I am trying to make an I2C slave that returns a fixed number of bytes to master upon being called with a read from the master (7Addr-Bits+1Read-Bit). In Debug-Mode it works, in normal run, it doesn't.I have thrown almost any HAL-functionality out, an...
Hi everyone,I am observing some data corruption in an external SDRAM connected to an STM32 F7 FMC peripheral and I am trying to understand what is happening and how to prevent it. Scenario:Configure the FMC to interface with a Winbond external SDRAM ...
Hello ST Community and Support Team, I try to play with Independant Watchdog and Window Watchdog on a Nucleo U575ZI eval board.I was able to configure counters, window and even EWI interrupt perfectly thanks to STM32 HAL library watchdog related func...
Heyho,I had probably some race condition, just want to make sure:the buffer switching in DMA's Double Buffer Mode (DBM) (both for DMA and BDMA) occurs immediately with the Transfer Complete (TC) interrupt?So when the DMA's TC ISR is entered (which ta...
Hello,I am using the Cube Code Generator, within the STM32CubeIDE (version 1.13.1) for an STM32H563, and have configured the Flash Data Sectors to use the maximum 8 sectors per bank for EDATA. The valid range for the EDATA sector size is 0 - 7, as sh...
Hello guys,Looking for "STM32F105/7, STM32F2 and STM32F4 USB on-the-go Host and device library" (STSW-STM32046) with version V2.2.0.I anybody able to share?Thanks,Max
Hi,If I configure the LSI as clock source my STM32C011F4U6TR code stuck at this pointHowever there is no problem if I configure HSISYS as clock source.Why? Could anyone help me with this issue?Thanks in advance,Gaston
Hi community, I am getting error in my stm32 microcontroller system which is used to communicate data of the sensor uart. Initially everything is working fine the adc data is coming perfect. Able to send data through uart without any error. But afte...
Hello. i'm trying to controll actuator by lin protocol. Which mcu is fit for me? and what i have to perchase more things? (for example, lin transceiver is need nor not, 1 more mcu for master-slave configuration) and which software i can use for it?...
