HiI have to connect an STM34 Nucleo board to a TMC2209. I have to setup a single wire UART. Only TX is connected with the TMC board.I transmitted a datagram and when I try to receive the response I get back the initial data I have e sent.Does anybody...
Hi,I am working on STM32F469NI using the USB OTG HS peripheral in CDC (VCOM) mode.When using USB CDC without DMA, the VCOM works fine.However, when I enable Internal IP DMA (from CubeMX → USB_OTG_HS → Parameter Settings → Enable internal IP DMA), the...
Product: SMT32C013Issue: firmware download in bootmodeDetails: I’ve recently started firmware development and, with community help, I’ve managed to create firmware for STM8 and several STM32 devices. Until now, I’ve always programmed the MCU using S...
Hi, is there a recommended minimum clock frequency to reliably run an RC5 transmitter with IRTIM?Thanks, Lance.
I’ve just started learning STM32 and I’m currently using the STM32F411E-Discovery board. I loaded the default code provided by the Board Selector in STM32CubeIDE and was trying to get a simple LED blink working. It works fine when using the internal ...
Hi,I have a STM32F103C8T6 configured to operate as an I2C slave device on I2C1. It operates as intended for 30-45 minutes before the I2C hangs indefinitely with a HAL I2C state code of 0x2A = HAL_I2C_STATE_BUSY_RX_LISTEN. In this state, further I2C t...
I’ve been experimenting with STM32 microcontrollers for a battery-powered IoT project. While I’ve tried different sleep modes, I’m still struggling to balance performance and battery life.Has anyone here implemented effective strategies for ultra-low...
Hi, Im new to STM32 and writing a bare metal interrupt based i2c library. For some reason addr bit clears itself automatically even though im not reading sr1 and sr2. I also have problems with debug mode, if i decide to step over the function that se...
I am trying to make a guitar loop pedal with my nucleo-l476rg board. It has 1MB of flash and I am trying to write and read from bank 2 only as it is the bank of memory I want to use for storing recorded audio. I currently have an active buffer set up...
