I am working with an STM32N6 microcontroller and need clarification about the electrical characteristics of its GPIO pins. How much current a GPIO can source and sink. Is it in micro Amps or mili Amps.
HelloSTM32H7R3L8I have trouble using the circular mode of GPDMA when trying to transmit data over SPI4. When I set the GPDMA channel 12 to be in circular mode, it generates the GPDMA channel init in the msp init file instead of the main file as if it...
I have a question about configuring pin D1 for UART1 TX (in conjunction with pin E2, UART1 RX).Pin D1 has the option for PA11, [PA9], PA8Pin E2 has the option for PA12, [PA10], PA71. To use pin D1 for UART1 TX, PA11 must be switched to PA9 (SYSCFG_CF...
Hi all,I am a newer STM32 programmer, and I have been working on the STM32H745 Discovery board for the last few months. Something that I would like to do is be able to switch into USB DFU Mode within a UI that I have made for this board. I took inspi...
Hi everyone,I’m working on an STM32 firmware project (HAL + CubeIDE). I’m trying to output debug messages to Tera Term via UART using printf and puts.Here’s the situation:Debug build: Both printf and puts work perfectly.Release build: Calling printf ...
Hi there,I am using STM32G473CBT6, and work with a bootloader and application.When I set the application address at 0x08008000, everything works well.However, when I change the application address to 0x0800A000, the application download fails, except...
HELLO ,In STM32F103C8T6, the RTC time is preserved after power off, but the date always resets to 01/01/2000 even if I set the current date and time.
Hi,I am using STM32L4R9ZIJ6 microcontroller.I have connected an external reference voltage of 3.3V to VREF+ pin and wanted to use internal reference voltage over this one for internal ADC read operation. Is that possible?I tried configuring the MCU t...
Dear STMicroelectronics Support Team,I am working with the STM32U585I-IOT02A development board, and I need assistance with the following:Entering and waking from low power modes (STOP2 or STANDBY) using the RTC wakeup timerConfiguring UART1 with DMA ...
Hi, I'm trying to configure an STM32H753 FDCAN peripheral to be compatible with both CAN-FD & CAN 2.0 frames, in both the Tx & Rx directions. How should I configure the FD-CAN peripheral to achieve this? I've been through he RM0433 document as best...
