My MCU is the STM32H723. To save GPIO pins, I would like to use the following architecture:- Connect external HyperRAM and Flash to one OCTOSPI bus. - Use multiplexed mode to access OCTOSPIM_P1 and OCTOSPIM_P2.- Map external RAM and Flash to differen...
Hi, i start design on G4 and am confused with internal ref in MX.1. Internal REF for ADC isnt real internal, but Vref2.Internal ref for comparators is 1/2 1/4 3/4 ... , but from what ?3. ADC stop working without VREF+ pin voltage, but comparator work...
Hello,I am trying to implement the following: a timer (tim3) is set to PWM generation, outputting a pulse periodically. Its TRGO triggers the DMA channel to request I2C to initiate a read transaction, read 8 bytes and generate an event interrupt (TC ...
Hi Team,I am currently working on a project involving the STM32F407G microcontroller, where I have configured MQTT to connect to a server. However, I am encountering persistent issues and have been unable to establish a successful connection.The spec...
Hi Everyone, I am using STM32F407DISCO board and made a simple program which transmit some values. The program is as follows #include "stm32f4xx_hal.h" #include "main.h" UART_HandleTypeDef USART2Config; void GPIO_Init(void); void UART2_Init(void...
hello: I use NUCLEO-H7A3ZI-Q to test a bootloader feature:the bootloader runs in 0x08000000 at flash, when it starts, it copies the application stored in 0x08005000 to 0x24000000 in RAM, then jump to 0x24000000, I turn on a led in main function to...
Hello everyone,I am designing an application with a machine learning core device (LSM6DSOX). I attended the webinar on machine learning core last week and following the tutorial from this webinar I need to use Unico-GUI software tool.I tried to dowlo...
I am looking to design a split keyboard that requires USB communication between two keyboard halves and a host computer. The left half will have a USB-C connection to a host computer and appear as a USB HID with regular keyboard functionality. This ...
Hello everyone.I want to connect 8 SRAMs (2MB) to STM32H755XIH3 and use them as 16MB work memory.When connecting 8 memories (SRAMs) using FMC (devices more than the number of FMC_NE*), how should I connect and control them? If there are any similar c...
Hello all,Im looking for LCD Display that I wanted to interface using ST32H747XIH6 Microcontroller, with its MIPI DSI 2 lanes interface. I see it can only support upto 800x480 in the datasheet, or am i wrong?, can the MCU drive larger resolutions lik...
