Hello,I am in the process of designing a product which is based on the STM32-H753 and requires P/SRAM.However, I'm concerned the H753 might not support on PSRAM with QSPI, I need the PSRAM for write/read.I haven't found any application notes or examp...
hello when i use UART Idle interupt with DMA on STM32H743XIH6 chip,i found ,the interupt function will run imediatly when HAL_UARTEx_ReceiveToIdle_DMA(&huart2, (uint8_t *)Uart2RxBuffer, 50)run,and this is my core code MPU_Config(); // SCB_EnableICa...
Post spread from STM32H745: No device found on target on a custom board Hi, and thank you for your previous answer and for pointing me to RM0399 / figure 22. I am quite new to the STM32H7 power configuration, so I may have misunderstood the datasheet...
Hello, I am trying to make a write into flash driver but I am having some issues.I know that the only way to write a 1 to the memory is by clearing the whole page, but I am having issues writing 0s.By reading the manual I encountered: Bit 2 PGERR: Pr...
We are working on a bare-metal application using USBX on an STM32N657X0H3Q device.In CubeMX, we configured USB1_OTG_HS under Connectivity and enabled USBX in Middleware. However, when we execute the following function: static void MX_USB1_OTG_HS_P...
Hi Team,As we are going to use RAM – IC CY62136EV30 (TSOP-44) in our new project with ST micro STM32F407ZG (LQFP-144).Do we need any impedance matching for 6-layer board?Can you please suggest the same. Crystal frequency we taken 16MHz for the MCU.Th...
I am implementing a high-speed, continuous UART loopback system using the GPDMA Standard circular mode on an STM32N6 series microcontroller. My setup involves autonomously linking UART_RX to UART_TX via GPDMA.The system is stable and the RX transfer ...
how to design the "NRST" pin about hardware?
I tried to follow this tutorial: How to build an AI application from scratch on the... - STMicroelectronics Community , could not figure out how to enable NPU RIF, so i skipped it. I tried to debug using the FSBL main.c, the blue led did turn on, but...
Hello,let say that STM32H753 mCU has connected VBUS (via resistor divider to be sure that voltage on VBUS detection pin (PA9) would never exceed AMR), D-, D+ and GND lines with PC, before mCU core is supplied. At the moment when mCU core is then conn...
