How can I interface stm32f469i to an e4000h QR code scanner?
I know that I will need to use UART. but I don't know how to see the data sent and received and on what terminal will I be able to see all this.

C++ compiler options.
Hi.I thought this question is more suited to education.I have been working on a STM32F091 C++ project just to get an idea code size, and I noticed that the size of the binary is huge even when optimisation is set to (-Os). I think its because the co...
SPI 3-wire bidirectional master not sending clocks
I have an issue with SPI in bidirectional mode (MOSI, CLK and CS). I have a device which I need to write to and from. When I have to write to an adress in the slave device, it works perfectly: reg=0x04; CS_DRIVER_LOW c=HAL_SPI_Transmit_DMA(&hspi2,...

stm32f4 TIM2 multiple channel input capture
Hello,I'm trying to write a PWM input capture function(I only need the on time. not the frq and duty cycle) and I see that it takes two channels of a timer. I need to use all four channels, Is it possible?Thanks
Unable to output floats using printf() after migrating to latest STM32 FW version.
From my functioning STM32 (H7) project, I open the .IOC file which spawns STM32CubeMX, which generates a dialog asking:"This project was setup using STM32Cube firmware FW_H7 V1.9.0. The new STM32Cube V6.3.0 works best with STM32Cube firmware version...
Resolved! I want to know how to clear bank1 securable area in NUCLEO-STM32G431RB.
I have configed the FLASH_CR，SET_BIT(FLASH->CR, 1<<27);I want to know how to clear bank1 securable area.
I'm using X-CUBE-SFXS2LP1 with STM32CubeIDE ("Easy portability across different MCU families, thanks to STM32Cube"). It has examples for NUCLEO-L073RZ, NUCLEO-L152RE or NUCLEO-L476RG, but I want to use something else. How do I do it?
X-CUBE-SFXS2LP1 is the S2-LP Sigfox expansion library for STM32Cube.There are no STM32CubeMX configuration files in the projects included in X-CUBE-SFXS2LP1, so how can I modify the MCU, GPIO pins, etc.? Maybe I'm missing a feature of STM32CubeIDE fo...
