Hi,I'm trying to build a small board using the STM32H723 MCU and my requirement is that I have one USB Micro B receptacle on the board for communication with the MCU. However, the communication should happen via USART and not the standard USB protoco...
Hi, I am trying to interface a PS2 controller with a STM32F103RBT6 board and I'm relatively new to STM32 in generally. I have understood how the PS2 protocol works and was able to find references with codes to run with. Unfortunately, the board confi...
i am using nucleo-f334r8 and when i connect to the laptop the MCU is hot but the voltage on the VDD does not exceed 3.36V. I want to use another MCU therefore I want to use the DEBUGGER (top part) also what should I unplug (jamper) or should I connec...
I was sitting down to start getting to grips with SDIO and FATFS when I realized that the only microSD breakout I have literally lacks the pins for it (missing an eighth pin for 4-bit data). I was already considering getting another NUCLEO board, but...
Good afternoon,I am attempting to write a bare metal C driver for an interrupt specifically on GPIOA8 for the nucleo-g031k8 (Cortex M0+). I believe there is an issue with how I am changing the register EXTICR in the EXTI. According to figure 29 (pg 3...
Hello,I am trying to use the USB HS on the Nucleo-H7S3L8 dev board.I was using the USB HS on the STM32H7A3ZI, it was using the physical layer but limited to FS, and it was easy to configure, but i need to change boards to have the HS USB.The ioc is c...
We are using STM32H753I-EVAL2 evaluation board. We need to test SPI functionality of microcontroller. The board gives a provision to use CN6 & CN7 connector to do this. But the Samtec connector couldn't be connected with any jumping wires nor we coul...
i am using stm3210e-eval board which has stm32f103zgt6 mcu and i trying to send data on its uart but i am not able to receive any. i am trying to receiving it through blocking mode uint8_t rx[10]; HAL_UART_Receive(&huart2,rx,1,HAL_MAX_DELAY); HAL_D...
Hi,I have a Nucleo-144 F722ZEI am attempting to program it with the arduino 2.3.2 ide.And so far, no blink, no digitalWrite() and no Serial.println()Details are listed below.Thank you in advance. I am sure it is trivial, and apologize for having t...
Hi,I am working with B-U585-IOT02A.In all example project using NetXDuo stack tcp/ip (web server, Azure Iot Hub, ecc. ecc.) the communication with wifi mxchip is performed by SPI using IPC -HCI command protocol.I haven't found documentation about com...
