Hello,Is it recommended to implement an ESD protection on SWD lines of STM32L011D3/D4 mCU? I went through "Getting started with STM32L0xx hardware development" document and there is a Figure 15 which suggests to connect SWD lines direct to programmin...
Hello all,This is regarding the the problem after recent development from 18MHz to 22.8 MHz of operational speed of STM as slave operating with DMA transfer and SPI mode 01. Although the data sheet suggest maximum achievable speed of 31 MHz - I made ...
Hi,I'm planning to use STM32H562ZI as I3C controller with an I3C v1.0 compatible Target endpoint. Since STM32 I3C IP supports I3C v1.1.1, will there be any potential issues on RSTDAA, ENTDAA, I3C Private Write, I3C Private Read or other electrical pa...
Ive been trying to get active passthrough between my adc and dac from pa1 and pa0 respectively. Ive confirmed all my functions are being called but i just cant seem to get any value loaded into my DAC. if i give it a value manually, i get the correct...
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.
