With the STM32 in stop mode 2, is it possible to use the RTC as a additional low power timer?I mean to trig IRQ periodically.I tried the PWR_STANDBY_RTC STM32Cube_FW_L4_V1.14.0 example for STM32L476 and the code never stop at the breakpoint in function RTC_WKUP_IRQHandler(). What's more, to avoid debugger I tried to set the LED2 ON inside this function, but the LED never lights up.

Hi All,Can anyone suggest a STM controller supporting following features.1) 1 I2C Port.2) 4 UART Ports.3) 20 Gpios4) 1 RGB LED PinThanks,Ashok

Hi there, we want to use the ST25R3911B on our own board, so I've implemented the whole SPI communication in a Xilinx Zynq FPGA. So SPI communication is tested and working, so reading writing to registers is no problem.Now I have to implement the RFID protocols, which are nicely provided by ST. So I've downloaded the software implementation from:https://my.st.com/content/my_st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-nfc5.license=1552982656184.product=X-CUBE-NFC5.version=1.3.0.htmlTo save some wires (interrupt wires), instead of interrupts I do poll the interrupt registers on every function call "st25r3911CheckForReceivedInterrupts".So running the main.c of this example, the process got stuck in a while code of the example:static ReturnCode rfalTransceiveRunBlockingTx( void ){   ReturnCode ret; // following while loop will never finishd:   do{      

Is it possible, to zoom a text and especially text with dynamic text?The scenario is, to zoom into a screen, if a user is detected by a sensor.

Hello,I'd appreciate if you could release a tentative list of the widgets you plan to integrate in the future release of TouchGFX with a few words about their features. Thanks in advance,Guillaume.

Hi,I have a STM32F407 Discovery kit, I'm working on costum bootloader program. I writed my codes, make the necessary changes in the Flash.id file with CubeIDE. I want to write bootloader section (0x1FFF 0000 address system memory) with STM32 ST-Link Utiliy but it is error. How can i write system memory my codes? Thanks..

I get and install CubeMX 5.0.1In page Pinout&Configuration->GPIO I havent all GPIO (look screenshot)

Hello. I have this init TIM3:void Start_Timer_3(void) { LL_TIM_InitTypeDef TIM_InitStruct;   LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM3);   NVIC_SetPriority(TIM3_IRQn, 3); NVIC_EnableIRQ(TIM3_IRQn);   // 50MHz clock // 1000 Hz, upcounting 32-bit // 1000 = ( 50000000 / (Prescaler+1)) TIM_InitStruct.Prescaler = (uint16_t)50000 - 1; TIM_InitStruct.CounterMode = LL_TIM_COUNTERMODE_UP; TIM_InitStruct.Autoreload = 0xFFFFFFFFU; TIM_InitStruct.ClockDivision = LL_TIM_CLOCKDIVISION_DIV1; TIM_InitStruct.RepetitionCounter = (uint8_t)0x00U;   LL_APB1_GRP1_ForceReset(LL_APB1_GRP1_PERIPH_TIM3); LL_APB1_GRP1_ReleaseReset(LL_APB1_GRP1_PERIPH_TIM3);   LL_TIM_Init(TIM3, &TIM_InitStruct);   LL_TIM_ClearFlag_UPDATE(TIM3); LL_TIM_EnableIT_UPDATE(TIM3);   LL_TIM_EnableCounter(TIM3); }And here is my Handler:void TIM3_IRQHandler(void) { LL_TIM_ClearFlag_UPDATE(TIM3); // breakpoint atc.... here }And my handler isn't working. Any idea, why? I try

Hi, I am looking forward using the TIM20 timer as per datasheet says on a STM32F303RE (nucleo-eval board) but the STM32CubeIDE only show timer up to number 17.Is this a bug?Thanks.Cyril.

Hi, everyone, I use STM32MP157C-DK2 on my macos(Mojave) laptop. I saw other threads the stlink can not install some driver on macos. but I can not see any /dev/tty.* device, Does I missing some config thing?

Sorry for such a newbie question....I can connect and debug in CubeMX, was trying to get a project started in CubeIDE.I can select the CPU, but I don't see the board package. Is there some initialization I might be missing? IDE connects, then pausing debug, it is in the fault loop.

I see the package dimension data in the datasheet, but do not see the suggested PCB footprint dimensions for the UFDFPN12 package . Not can I find any CAD footprints or 3D models for it in the Stmicro site. Where are such things?

Hi All,I am working with the STM32F302R8. I want to set the system clock as the PLL through derived from the HSI. I want a clock of 64MHz which I should have set through the appropriate registers.I think I have set all I need however, after the RCC configration is done, the system clock switch status (SWS) in the RCC->CFGR register still indicates 0x00, initiating that the HSI is used as a clock directly.I have a blinky at the end which currently the LED stays on while the code is running and never turns on when I am debugging.#include "stm32f302x8.h" int x =0;   void Delay (uint32_t nTime); uint16_t ADC1ConvertedValue = 0; uint16_t ADC1ConvertedVoltage = 0; uint16_t calibration_value = 0; volatile uint32_t TimingDelay = 0;   int init () { //RCC->CR = 0x1; //HSI on RCC->CFGR = 0x003C0002; //PLLSCr = HSI/2 , PLLMUL = x116 (62Mhz), PLL = sys clock RCC->CR |= 0x01000000; //PLL on RCC->AHBENR |= (1<<18); //Enabling AHB GPIOB //RCC->AHBENR |= (1<&

Hi,I use the STM32CubeIDE to generate the code of STM32L4 Discovery kit IoT node (B-L475E-IOT01A) and I have added code to use printf command. I can send text to HyperTerminal except ">" as code below.printf("\fSTM32L4 Discovery kit IoT node (B-L475E-IOT01A)\r\n>");But I tried to use code below. It can send ">".uint8_t Text1[1] = {'>'};HAL_UART_Transmit(&huart1,Text1,1,100);Could you advise me to solve this problem?Thank you

Hi,Actually now I'm working on the FlexCAN boot operation and I have few queries to be addressed to start over. I have this rudimentary question for an embedded engineer, sorry for it. how do I know the code length/size of my software? while pushing code on SRAM via FlexCAN boot, what should be the register value for PCONFx registers? In the 3rd step of FlexCAN boot sequence, how do I push my software to the SRAM? Please help me with the files or process or the sequence in which the code has to be pushed serially in CAN ID 0x013Thanks for your time in advance.Best Regards,Prashanth Mohan

Hello,I hope someone can help with this riddle.We just started working with our custom board, based on stm32h743 (untill now we worked with eval stm32h743-eval board).The internal memories, GPIOs and other interfaces works OK, but we have the following strange issue with the external sram:In our test we write 0x400 bytes (0x200 16-bytes words) and read these 0x400 bytes and compare values.Reading from sram immediately after writing works OK, ( we get the same values we have written for all the 0x200 16-bytes words), but if we stop at breakpoint and open memory debugger for addresses starting from 0x68000000 just after the reading and do a step , then the memory in 0x68000000 .... changes from the correct written values to 0xfffffff .... We suspected that it is issue of debugger view of memory, but we see similar behavior even if we close all memory views: when we just toggle a led after the reading, and do again a reading of 0x200 words we then see that only some values inside the 0x40

Hello,We intend to use a font which was installed correctly but was not listed in TouchGFX under the Font column in Typographies.After some investigation, we found the font contains a space in its filename, e.g. "Sample Font.ttf". After removing the space and reinstalling the font it is listed correctly.The workaround to remove the space and re-install the font works fine for now, but requires each developer to follow this step for a font that is pre-installed on our computers - hence this bug report.

Hello​.I have got a bootloader and application that both work separately.I want to combine from both file to one hex file using SPC5studio.Is there any option and setting in SPC5studio?Thank you in advance.

Hello,I was searching this forum and already found lots of help, but unfortunately I'm stuck to this issue. The Guide refers to CubeMX 5.0 and some things seem to be corrected since this version i.e. C/C++ combi project... but still CubeMX does not generate an Atollic project including TouchGFX that does compile and so far I was not able to fix it. Actually this is bit frustrating as TouchGFX together with the other stuff is all part of STM and promised as working solution...So Maybe someone here has done this succesfully and would be so kind to share the .ioc file or give an updated step by step manual for the new software release as I'm sure I just miss some tiny things...Thanks in advance and best regardsStefanPS: Without use of TouchGFX I can create a working project with CubeMX and also when I use the TouchGFX standalone and flash the Board from the Designer it works.

I am trying to run a clock demo from TouchGFX 4.10.0 Designer for my STM32F769-DISCO.But when i Run on target the detailed log shows the erroe:" there is an error occured during flash.  Please make sure you have the right target connected."PS:I am sure that i have choose the right target.

How to get interrupt state (enabled or disabled) via HAL?In my void I need to do HAL_TIM_OC_Stop_IT() only if this interrupt enabled.

Is there any example source code that I can use for controlling CR95HF from user space application in Linux using UART?

Hello,I read ref manual part about SYSCFG (STM32H7 in my case). There are some regs that have an undefined reset value and the meaning of the regs is so that the contents is important at HW reset (BOOT_ADDx, BANK_SWAP). These regs are marked read only. I couldn't find anything, how to set the values and where they are stored. Can I change them somehow from my software, ie change the boot address or swap the banks for the next reset?General topic is to design a custom bootloader that will also be called after reset when BOOT0 is set. Also a fall back to the previous version after a corrupted firmware upload would be nice.Thanks a lotMartin
