I am using the Nucleo-L433RC-P board and have configured pin PC13 as SYS WKUP (for the blue top button).How can I read the state of this pin when the processor wakes up, because HAL_GPIO_ReadPin will not work.I am sure I used a function or macro to ...
Hello friends : )I've recently tested the NUCLEO-G491RE board for an upcoming redesign.Current design relies on quite tough interrupt latency so here is where I begun.As I understand, with no FPU usage (in isr) (ASPEN + LSPEN = 0) one could expect up...
Hello team,Generally , Reset pin by default status is Logic High.But in AN4206 ( Page 31) , NRST pin is not Connected to 3.3V , it is left Floating with Capacitor.Is that Okay ? My device is STM32F303.Regards,
Hi, I´m reading the following document : "an4879-introduction-to-usb-hardware-and-pcb-guidelines-using-stm32-mcus-stmicroelectronics" to implement USB in my application. In section 2.6.1 Simple Resistor Divider it says "This solution works well as lo...
Apologies for the ignorance, I'm a beginner with STM32 and I purchased the STM32C071K8T6 MCU since it has built-in USB capabilities. I am trying to implement USB CDC, but I'm becoming quite confused with all the USBX and ThreadX stuff I have to enabl...
Hi,In STM32U5, the GPDMA has both request sources and trigger sources, what's the difference between them?Thanks.
Hi everyone, for several days I've been trying to replicate the Nx_TCP_Echo_Server application example by creating a project with the .IOC file, but I can't establish Ethernet communication. If I compile and run the example, everything works, but m...
Hi Folks,I’m currently observing flickering on a 10" TFT LCD screen and would appreciate some expert advice regarding the connections for LCD_CLK, LCD_HSYNC, and LCD_VSYNC.At present, the signals are connected as follows:MCU LCD_CLK → Non-Inverting B...
Is it possible to connect 8 PDM microphones to the STM32N6 via MDF?
I am trying to set up DFSDM on an stm32h753zi using the AMC1306 delta sigma modulator. I have enabled TIM8 as a trigger:But in the registers I see, that JEXTEN is not set to external rising edge (0x1). Instead it is set as disabled (0x0).After the Cu...
