Hello, I'm writing regarding use of the stm32-can-bootloader that is linked on the https://github.com/effenco/stm32-can-bootloader and also is mentioned in the topic https://community.st.com/t5/others-hardware-and-software/serial-programming/td-p/63046  We use this bootloader code for the STM32G0B1CxT and it works fine programming via PD0/PD1 (FDCAN1) interface.We'd like to use it on the PB0, PB12 (FDCAN2) interface but with no success - there's an error on the bus that looks like the programmer can't send data to the PB0, PB12.Configuration for the both FDCANs is the same and they are both enabled to receive during flashing. I'm not sure if it's connected with the limitations mentioned in the manual (screen is attached to the message). Additional details: The initial code is generated by the cubeMXHAL_FDCAN_RxFifo0Callback() is not called for the FDCAN2 in the bootloader modeThe FDCAN2 used in the application code works fineDo these limitat

Hi Cube/Gfx Team,Cube 1.16.1 and GfxDesigner 4.24.1 generate different .cproject outputs. In a commit on the left, rows 2 and 3 are on separate lines but in newly generated .cproject these are combined into single line 2 on the right. Also spaces are replaced with tabs.Could this be somehow 'fixed' ?Thanks

I've been reading through the Wake-Up Mode and Automatic Antenna Tuning application notes, and while I understand that AAT and Wake-Up with inductive sensing require more involved software wake-up logic, it doesn't seem to me that capacitive sensing would. For inductive sensing with AAT, the AAT outputs are left floating during Power Down Mode, so upon wake-up, they need time to settle for an accurate measurement.But the capacitive wake-up is a separate mechanism that has nothing to do with AAT or the NFC antenna. Is there any reason that AAT + capacitive wake-up wouldn't work together?edit: this is for the ST25R3916, with custom firmware

Hi there I'm working on a project where I need to create 4 different pulse trains on 4 different GPIO pinsI've created and formatted a uint32_t array to be able to directly write to the GPIO BSRR registerI want to use DMA memory to peripheral in circular modeTo trigger the DMA transfer I need to pick a timerAccording the the drawing on page 151 in the reference manual for STM32F030F4P6 it looks like there are trigger inputs from the basic timers TIM14, TIM16 & TIM17 to trigger the DMA transfer But all the examples I've been able to find in videos and in descriptions are all using advanced timers and are using an trigger event TRGO to trigger the transfers of new data from memory to GPIO port at fixed intervalsWhen I'm looking on the setting options for these basic timers TIM14, TIM16 & TIM17, I do not have any option for an trigger event (TRG0) from these timers. I'm only able to pick Input Capture, Output Compare & PWN generation from the available options in Cub

I would like to use the CAN interface with a CANOPEN library on my STM32F723.As I have found there is a Library for STM chips provided by emotas: https://www.st.com/en/partner-products-and-services/canopen.htmlI have downloaded the Lib on my STM32CubeIDE an now are trying to add it in my CubeMX to the Project: The problem is, it says, its not supporting my MCU. But in the description of the Library it says it should support the F7 chips.Is the library not "free" and I have first to contact emotas or did I forget to install something? Best regards,CO

Hi, I am currently using the SPC58EC series of microcontrollers. I would like to know, for an I/O (configured in input mode), at what input voltage level it will be recognized as a high level. Is this voltage value configurable? Thank you for your reply. Thank you.

I wasn't able to find the STM32 MC SDK reference manual. Can anyone share a link ?

Hi everyone,I’m a beginner with STM32 boards and I’m trying to understand and work with the BLE 5.4 PAwR feature. I have a NUCLEO-WB09KE board, and I’m using Windows 11 along with the STM32Cube_FW_WB0_V1.1.0 package. I have installed all the required tools: STM32CubeIDE, STM32CubeMX, and STM32CubeProgrammer.I’m trying to replicate the example from this workshop video:Workshop Video – BLE PAwR ExampleI’ve also reviewed the README.md files in the following repositories:1. STM32WB0-BLE-PAwR-ESL2. STM32WB0x-Demo-WorkshopHowever, in the examples located at:…/Projects/Applications/BLE_PAwR_Broadcaster…/Projects/Applications/BLE_PAwR_ObserverI couldn’t find any folder for STM32CubeIDE (or a corresponding .ioc file). Only folders for IAR (EWARM) and Keil (MDK-ARM) are present, but I want to work with STM32CubeIDE.Could someone please advise:Is it possible to convert an EWARM / MDK-ARM project to STM32CubeIDE and generate a .ioc file?What is the recommended step-by-step procedure to create a ne

I would like to deploy a model on a microcontroller but would like to have an idea of what the inference times would be on different ST microcontrollers before getting one.Is it possible to emulate how a model would run on a specific microcontroller using CubeAI by "validating on desktop"? There is an inference time per sample metric in the generated Cube AI report when I validate on desktop, but I am guessing this is inference time on my computer's CPU and not an emulated microcontroller.   

Hi everyone,I'm working with an STWINBX1 board and using ST-LINK V3MINI for debugging and serial communication.

I am implementing encryption and decryption using AES-GCM mode on the STM32 NUCLEO-U5A5ZJ-Q. I have successfully encrypted and decrypted the string "Hello", but I am having issues with tag authentication.I am using the function HAL_CRYPEx_AESGCM_GenerateAuthTAG to obtain the tag after the encyption process.However, I cannot find a function to verify the tag. I have two questions:Do I need to implement the tag verification myself?If I need to implement it myself, is it correct to call HAL_CRYPEx_AESGCM_GenerateAuthTAG after both the encryption and decryption processes and then compare the tags? I obtained the tags from both the encryption and decryption processes, but different values were returned. Below is a portion of the implemented source code.  #define AES_KEY_SIZE 16 #define AES_IV_SIZE 12 #define AES_TAG_SIZE 16 CRYP_HandleTypeDef hcryp; uint8_t aesKey[AES_KEY_SIZE] = {0x11, 0x11, 0x22, 0x22, 0x33, 0x33, 0x44, 0x44, 0x55, 0x55, 0x66, 0x66, 0x7

Hi all,I'm designing a product that will have a USB boot-loader.I would like to choose a micro-controller that supports secure-boot as well as an ability to completely lock down the micro-controller such that no flash can be read from it. I understand this to be read out protection. Please correct me if I'm wrong.What's the best way to sort ST's micro-controller offerings based on the criteria above? If anyone has recommendations for micros, that would be greatly appreciated.Thank you!

I have two Nucleo boards, both NUCLEO-L476RG. The first board is equipped with the X-NUCLEO-NFC08A1 (ST25R3916B), while the second board has the NFC 5 Click board (ST25R3918).I am trying to establish peer-to-peer (P2P) communication between these boards, with the ST25R3916B configured as the initiator and the ST25R3918 as the target.Both boards successfully detect NFC tags, confirming that the basic hardware setup is functioning correctly. However, I have not been able to achieve P2P communication.Any guidance or assistance in resolving this issue would be greatly appreciated. I have attached the initiator and target codes for reference. 

Hi am relatively new to stm32 development.I would like to understand the difference between HAL_GPIO_EXTI_CLEAR_IT and HAL_GPIO_EXTI_CLEAR_FLAG Thank you!

Is there a way to split the XPSR register view up so you can see each status bit by its name rather than the 32-bit value?The SFRs have this feature, why do the general registers not have it enabled by default?

I need a second pair of eyes. I am trying to setup EXTI using the GPIO HAL. But it looks like its doing it wrong. It must be me but I need you to double check to be sure.This is STM32G0 HAL so stm32g0xx_hal_gpio.c /*--------------------- EXTI Mode Configuration ------------------------*/ /* Configure the External Interrupt or event for the current IO */ if ((GPIO_Init->Mode & EXTI_MODE) != 0x00u) { temp = EXTI->EXTICR[position >> 2u]; temp &= ~(0x0FuL << (8u * (position & 0x03u))); temp |= (GPIO_GET_INDEX(GPIOx) << (8u * (position & 0x03u))); EXTI->EXTICR[position >> 2u] = temp;  In this code sample the macro GPIO_GET_INDEX is used. It takes the value "GPIO_TypeDef *GPIOx" and this value will enter the function as  GPIOB, GPIOA etc. The macro is  #if defined(GPIOE) #define GPIO_GET_INDEX(__GPIOx__) (((__GPIOx__) == (GPIOA))? 0uL :\ ((__GPIOx__) == (GPIOB))? 1uL :\ ((__GPIOx__) == (GPIOC))

Hello everyone,I'm trying to get an RTC output on pin C13 using a Bluepill STM32F103C8T6, but it's not working.I have connected LED to PC13 to see the LED blinks every 512hz but its on all the time.Can someone help me.

I am using a STM32F103 and having issues to make an USB application.I generated the project using CubeMX and I am not being able to transmitt a message.Here is the configuration:Main is like this (It is C++ in case it matters): int main(void) { HAL_Init(); SystemClock_Config(); MX_USB_DEVICE_Init(); while (true) { HAL_Delay(100); volatile uint8_t result = CDC_Transmit_FS((uint8_t*) secondLine, strlen(secondLine)); if (result != USBD_OK) { } } }   After inspecting in debug mode the CDC_Transmit_FS function I saw it was returning "USBD_BUSY": uint8_t CDC_Transmit_FS(uint8_t* Buf, uint16_t Len) { uint8_t result = USBD_OK; /* USER CODE BEGIN 7 */ USBD_CDC_HandleTypeDef *hcdc = (USBD_CDC_HandleTypeDef*)hUsbDeviceFS.pClassData; if (hcdc->TxState != 0){ return USBD_BUSY; } USBD_CDC_SetTxBuffer(&hUsbDeviceFS, Buf, Len); result = USBD_CDC_TransmitPacket(&hUsbDeviceFS); /* USER CODE END 7 */ return result; }  I saw that hcdc

Hi everyone! I'm trying to run the STM32N6 (using the STM32N6570-DK discovery kit) in Execute-in-Place mode. I followed the official tutorial for this, and everything works fine. The tutorial uses very low clock speeds for the CPU and AXI, namely 64 MHz, which is of course way too slow for actually using this. Increasing the CPU clock (SYSA) in CubeMX to 600 MHz works fine. However, as soon as I increase the SYSB clock (AXI) to anything higher than around 120-160 MHz (400 MHz should be maximum?) it stops working completely. Of course I made sure that XSPI2 stays at 50 MHz all the time (because I did not enable the I/O speed optimization for higher XSPI speeds).Is there anything else that needs to be done in order to use the MCU at its full speed when doing XIP? I also tried a simple FSBL-only project (executing from RAM, so no XIP) and that works fine with 400 MHz SYSB clock. LRUN applications do not work, though, similar to XIP.Thanks a lot for your help, any tips are a

Hi, I recently started learning TouchGFX. And faced with the need to use the graphics work with the screen without the Touch panel. Instead, there will be physical buttons. Is there an example of how to implement this?

Does STM currently have a guideline or recommendation(s) for handling the 2038 problem?

Hi,STM32U5A5VJT6Q has 2 VDD11 pins. Should these be connected together using an external trace on a PCB? I did look at Nucleo U5A5ZJ-Q schematic but I'm still not sure.Thanks,Adam

I finally got the following code to function after forcing a compiler error to see what registers the compiler was selecting for the inline assembly output and inputs. What I found was that the compiler was using register R3 for both output (count) and the first input. To work around this I created an "unused" variable and made it the first item in the input list and did not use argument %1 in the code.Is this due to a bug or limitation in compilation of ARM inline assembly that results in the same register being used for output and the first input?   uint32_t numOnes(uint32_t value) { uint32_t unused = 0; // not used uint32_t bit = 32; // number of bits uint32_t count = 0; // number of ones asm ( "loop:\n\t" // loop "TST %2,#1\n\t" // mask for bit0 "BEQ continue\n\t" // branch if bit0 is 0 "ADD %0,#1\n\t" // bit0 is 1 so increment count # "continue:\n\t" // jump to here if bit0 is 0 "LSR %2,#1\n\t" // move next bit into bit0 position "SUBS %3,#1
