STM32L476RE immediately exits STOPMODE2 after entering, even though the HAL_SuspendTick() tick has been called prior to.I have a small C application running on an STM32L476RE and I am using FreeRTOS as an OS. I want to periodically enter into a low p...
Hi,I am running my Zephyr application from an OSPI external flash and would like to write to the same flash. The MCU is an STM32H730, and the flash is an IS25LP128.However, the flash_stm32_ospi_write method in zephyr/drivers/flash/flash_stm32_ospi.c ...
Meanwhile STM goes with Microsoft AZURE RTOS - ok, fine, feature rich, obvious! But "I miss a feature": open and read a file from the MCU internal flash memory (as a const file content, as array of characters, without a need for a sector based, FAT b...
Hi!I'm trying to make a LCD screen work, but without success.I found this library:https://github.com/STMicroelectronics/stm32-ssd1315But I can'd find more documentation with examples (how to initialize).Can you give me a "wire"? Now I'm using a ssd13...
Hello. I tried to initialize SDRAM (I am using STM32F746 discovery kit), but I try to run it as a separate project just for learning. However I encountered the following problem: when I read data from SDRAM in my case starting from 0xC0000000 address...
Hi, I am working on a custom project with the STM32H755ZI (Cortex-M4 core) using the SDMMC peripheral and FatFs to read from SD cards. The SD card is inserted into a slot on my custom PCB, and the SDMMC peripheral is clocked via PLL2, because of this...
Hello,I'm facing a bizarre issue with USART2 in STM32H7 chip.My H7 is connected to 8 F072 chips via UART. Communication with each chip uses a dedicated UART from 1 to 8.All the data exchanges in both RX and TX work fine during normal operativity of m...
Hello everyone,I’m working on an STM32H747IIT6 based project that uses both Cortex-M7 and Cortex-M4 cores. Under Pinout & Configuration > System Core > Cortex_M7 (and similarly Cortex_M4) in STM32CubeIDE, there are several options such as:CPU I-Cache...
Good afternoon,I'm using the STM32H723ZG Nucleo Board, and I'm trying to collect data using I2S + DMA coming from a PCM1803AEVM that is a 24-bit ADC used mostly for audio purposes.I've set the PCM1803 as controller (MASTER), it is generating the BCK...
Hi, I am planning to use STM32H5 series uController in one of our test card application, as part of it i am exploring different software offerings avaialble for that series.In doc, Embedded software solutions ST, 3rd parties and Open source (stm32-st...
