Hello,When I connect USB-C source power to our device, PD sniffer shows Source:DFP sends DR_Swap message to our device, which has a STUSB4500 PD controller. However, our device(Sink:UDP) always sends Reject command. My questions are:Does STUSB4500 support DR_Swap message?We want to swap data role based on PD negotiation, how to get the message and how to process it to reply Accept?Is there a register that record the DR_Swap message?From STUSB4500, is there a way to trigger to have PD source to send the DR_Swap message again?Thanks,Winston

My STM32MP157F-DK2 is powered by 5V 3A PSU. but at the boot up time, always it displays the warning *****************************************************    WARNING 500mA power supply detected    **   Current too low, use a 3A power supply!   *******************************************************At the end of the boot process, I do see following display as well:root@stm32mp1:~# [  33.112323] usb33: supplied by vdd_usb[  33.114843] vref: supplied by vdd[  33.118045] vref: disabling[  33.120724] vdda: disabling

Ok, I scratched my head long enough and now my hope lies with the ST Community. =) I would like to understand how this code in the header file stm32f1xx_ll_gpio.h works. In particular, what does (Pin >> 24) do? I suspect that the code sets two registers: GPIOx_BSRR and GPIOx_CRL. Here: Pin = LL_GPIO_PIN_5 GPIOx = GPIOCThank you.__STATIC_INLINE void LL_GPIO_SetPinMode(GPIO_TypeDef *GPIOx, uint32_t Pin, uint32_t Mode){ register uint32_t *pReg = (uint32_t *)((uint32_t)(&GPIOx->CRL) + (Pin >> 24)); MODIFY_REG(*pReg, ((GPIO_CRL_CNF0 | GPIO_CRL_MODE0) << (POSITION_VAL(Pin) * 4U)), Mode << (POSITION_VAL(Pin) * 4U)));}

I used ImageMagick to change a image into 256 colors that I want to used L8_RGB565 image. magick convert ***.png  -colors 256 ***_L8.pngBut the TouchGFX compiler returned an error : ERROR: Too many colors (762) for palette. Consider using RGB565. ERROR: L8_RGB565 image assets/images/***_L8.png has too many colors for palette. Consider using RGB565.

Hi!I'm using FC-12M 32.7680KA-A5 LSE crystal and my STM32F373VBT6 won't start if I'm suing LSE crystal. But if I'm suing LSI crystal, then my STM32 will start.I have made two(2) boards and both of them LSE won't start.  My suggestions why are:To big capacitorsSTM32F373VBT6 is brokenThe crystal is brokenBug in STM32CubeIDE 1.6.1Crystal is to far away from the MCUWhat do you think is the right according to the information below?My setup looks like this. I'm using 15 pF capacitors because I computed them with the formula:C = 2(CL - Cs) = 15Where CL = 12.5 pF is the load capacity of the crystal.Cs = 5 pF is the stray capacity of the board.The PCB layout for the LSE crystal. PC15 and PC14 is it mounted at. I have followed recommended CubeMX setupI have selected the correct LSE crystal according from the recommendations from ST.And the crystal information looks like this: 

What does BCD™ “offline�? technology mean? Can someone provide a definition or explanation of what the BCD offline technology mean? Its in a datasheet I am reviewing for part number L6384E if that helps.

It does parse global variables in the corresponding .elf file of the same project, compiled in Debug mode (without optimizations). The introductory video (of Cube Monitor) said it can parse debug and release .elf files, but it does not seem to be the case.

Hello , I had started a project with STM32F410RB wish communicate with a keyboard and LCDActually i wrote my program that call SysTick_Handler from stm32f4xx_it.c to interact keyboard and detect if there is a button pressed and wrote caracter on LCD. Everything in going  well until here.Now i would like to integrate RTOS on my project to communicate with other board and i'm planning to create 2 task, one for (keyboard/LCD) and one for the other boardI would like to hear from your experience if i'm making mistakes and what things should i take care about?Thank you in advanceBest Regards,

I am using an IHM07M1 with NUCLEO-F446RE, and a rather large BLDC motor.If I use a 24V supply voltage the ST Motor Profiler 5.Y.1 is able to complete fine, but when I connect my 48V supply the profiler almost immediately fails once I start it, I don't see any movement in the motor.I looked at the jumper configuration on the board and I don't think there is anything wrong with it. The 48V supply is not destroying my setup, I can go back to the 24V and it works fine.Is there some rework or other configuration that needs to be done to scale a measurement or something to support the higher voltage?Thanks,-KylerEdit:Did some testing with a bench top power supply, the profiler seems to fail once the voltage supply is about 36V or more.

I follow the ST25PcDemoApp_software_guide in ST25SDK-1.8.0 but I encountered an error at streader.dll."java.lang.UnsatisfiedLinkError: C:\Users\DengKai\workspace\st25PcDemoApp\resources\windows\x86\streader.dll: %1 is not a valid Win32 application"How do I solve this error?

HiI've declared virtual void handleTickEvent() in the header file of my container.In my cpp file of the container I would like to update my battery bar on every tick:void BatteryBar::handleTickEvent() { if(tickCounter >= 100) { tickCounter = 0; } UpdateBatteryBar(tickCounter++); }I'm not getting it to run. It never enters to handleTickEvent().What else do I have to do to enable the tick event?RegardsDejan

I encountered a very weird behaviour when trying to erase the Flash memory of the STM32H745ZITx on the Nucleo-H745ZI-Q board using the STM32CubeIDE on Linux. While running the code: HAL_FLASHEx_Unlock_Bank2(); for (int i = 0x0; i <= 0x7; i++) { FLASH_Erase_Sector(i, FLASH_BANK_2, FLASH_VOLTAGE_RANGE_4); } HAL_FLASHEx_Lock_Bank2();I get the following debug output:STMicroelectronics ST-LINK GDB server.

I'm trying to blink a LED once per second, using the SEC interrupt.I'm rewriting a NIXIE clock I wrote, that used a home-brewed dly() function, so the remnants of that code are still there, sorry about that.According to Ref Manual I have, if the SECIE bit is set, I should enter the RTC_IRQ.My code reads as follows:#include <stm32f10x.h>   //__iar_program_start volatile unsigned int clckH=0; volatile unsigned int clckM=0; volatile unsigned int LED_Status=0; //Status of LED connected to PC_13 volatile unsigned int BNRY_CNTR=0; //Counter for Nixie prototype test   void delay(long dly) { int cntr = RTC->CNTL; for(int i=cntr;i<(cntr+dly);i++); }   void PLLEnable(void) { RCC->CR |= RCC_CR_HSEON; while(!(RCC->CR & RCC_CR_HSERDY)); RCC->CFGR |= RCC_CFGR_SW_HSE; RCC->CR &= ~RCC_CR_HSION; RCC->CFGR |= RCC_CFGR_PLLMULL9; RCC->CFGR |= RCC_CFGR_PLLSRC; FLASH->ACR |= 18; //Enable FLash Prefetch due to high PLL speed.

Hi, I am using SPC584b60e MCU, I have to write several hundred byte of data at Customer OTP region which is there in first block flash memory. I am not getting how I can start. I have following question1) Can I use C55 flash module API to write at this region, if so how I can start, because I don't see any example for writing at OTP region in SPC5 studio ?2) Can I write data here word by word (32-bit at a time ) instead of whole block write ?3) What is sequence to initialize, unlock and write at this customer OTP location.Please provide if any example code is available Thank you

What's the maximum amount of current which I can draw from a NUCLEO-L476RG output pin? (in order to power a light source) Is there a limit per pin as well as an overall limit for the whole board?

Hi All,I am interested to use STM32H7 Dual core for my project. To save component and space, May I use it without external oscillator?Thanks

Hi there,I am new to SPC5studio and SPC560P family. I recently tried to build my coworker's project but it got three errors (lvalue required as left operand of assignment)(make: *** [components/spc560pxx_platform_component_rla/lib/rsc/rules.mk:133: build/obj/swirq.o] Error 1)It works just fine on my coworker's laptop and I cannot figure out what the difference is between me and my coworker's IDE settings. (I opened the project through Open Projects from File System. )Then, I created a new project "SPI_test" and there is another error popped up. (make: *** [components/spc560pxx_platform_component_rla/lib/rsc/rules.mk:137: build/obj/main.o] Error 1)Do I need to clean the generated files and rebuild? I cannot seem to solve the errors. I have scrolled through half of the community pages and did not find any answer.Hope to hear some advice

Hi, I'm the beginner in MCU programming.I know that SPC574S communicate with L9963 through SPI, but how do I actually programming in SPC5 Studio to get the data read by L9963 ADCs ?I think I need some basic introduction and some DEMO lessons from reading datasheets to coding. Anyone can help with that? Thanks in advanced.
