We are designing a PCB based on the below products.We need the project files for the following boardsB-L475EIOT01A2C - Discovery boardNUCLEO-WL55JC - End nodeP-NUCLEO-LRWAN2 - GatewayWe are using Altium Designer. If the files are in different format, we can import them in to Altium. RegardsShaun Thirukonda

Hello,I'm trying to define some GPIOs as simple input/output for STM32MP157. I'm using the STM32CubeMX tool, but I can't find where to assign the GPIOs to A7 or M4. In the pinout view, I correctly set them as input/output but when I generate the code, I don't find their definition, nor in the device tree .dts, neither in the m4 code (only clock enable is present).Thanks

I would like to know if the example project is working normally. Thank you.

I'm using STM32L562VET6, please tell me where I can find "X-CUBE-CRYPTOLIB" support Cortex-M33.Thanks,QiZhang

Hello,I would like to use a reset circuit with a push-button for STM32WB55 MCU. The datasheet of the MCU gives a diagram which is uploaded to the attachment. As I understand, I use just a push-button and a capacitor. VDD and pull-up resistor is involved internally.  But, in many example schematics which is published by ST shows that there are a pull-up resistor and VDD connection externally. And sure, the circuit is connected by an active-low signal. So, I need a VDD with a pull-up resistor.  The question is that whether I have to use a VDD connection with a pull-up resistor in the reset circuit or not necessary. Thank you,Batuhan

From reading the ST25R3916 datasheet, it seems like using the MCU_CLK output as my microcontroller clock source will ultimately generate less undesirable noise and save on additional parts. My mcu and rf circuit will all be inside the antenna much like the str3911b-disco. However, I notice in the str3911b-disco design that the mcu is using an external 32 khz crystal instead and that mcu_clk is disconnected? Why didn't they use the MCU_CLK pin for this board?

I am using an STM32 MCU. When I use the HAL_Delay function with a parameter of 1000 for example, I see that the delay is shorter than it should be. I have checked that HAL_IncTick(), but it works correctly and it is placed inside the SysTick_Handler. What do I need to check in my code? Or it could be a problem with some configuration made with Cube ? Thank you in advance.

At first, I thought that the SWD function was disabled. After trying reset and boot0 pull up, they couldn't do it, nor could they use JTAG mode. What is the difference between the two ways? Or any special burn settings

Hello, everyone,I test CANFD a long time. And I found that some Bit Rate doesn't work together. For example, I use CANFD Mode, set to 1M + 5M. It work well. But same parameter at Data Bit Rate，I change to 500k + 5M， or 250k + 5M， it can't work. It always show me Bus-off. And I watch FDCAN_ECR register, TEC is 0xff. It mean some wrong on CAN Bus. I try to check the CANH CANL in oscilloscope. I found the signal is error at the end of CAN Message.

Hi, I would like to ask, I have a SPI setup Full duplex which my STM32f302R8 nucleo board as a master and arduino UNO as my slave.I send a data 0x0C from master to slave. During transmission, I know that the slave will return a dummy data back to the master.So, I would like to ask, let say I want the slave to send data 0xF5. How do I handle the dummy data that is sent back during data transmission from master to slave? In order I want to make sure the master will only receive the real data which is 0xF5 from slave.Example: Master send 0x0C to Slave. Then, slave return dummy data also 0x0C during data transmission. Then, the slave will send 0xF5. So, how do we handle the dummy data before the master receive the true data which is 0xF5?

We are having issues with STM32MP157 UART7 (address 40018000) exiting low power CStop mode and waking up Linux (v4.19 from ST github).We have confirmed that CStop mode is entered, and it can be exited using an external interrupt (55 pmic_irq), however it does not exit CStop mode with UART7 RX.The stm32mp175c.dtsi defines uart7 interrupts as GIC interrupt 82 and EXTI interrupt 32, and defines the uart as a wakeup source   uart7: serial@40018000 {         ...         interrupt-names = "event", "wakeup";         interrupts-extended = <&intc GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>,                    <&exti 32 1>;         ...         wakeup-sou

I am trying to take a microphone sample every 62.5 microseconds (16,000Hz) which is the standard rate for audio files. The problem i have found is that HAL_SAI_Receive_DMA() returns HAL_BUSY for some samples. So we dont receive the required 16,000 samples in the 1 second, it only manages 14750.The SAI component can reach rates of 192KHz so it makes no sense that it cannot handle 16KHz? So how do i fix the problem of receiving HAL_BUSY?Thanks!Here is an example sketch running on an STML452RE:#include <SoftwareSerial.h> #include <Arduino.h> #include <HardwareTimer.h>   #include "stm32l4xx.h" #include "stm32l4xx_hal.h" #include "stm32l4xx_hal_def.h" #include "stm32l4xx_hal_gpio.h" #include "stm32l4xx_hal_sai.h" #include "stm32l4xx_hal_exti.h" #include "stm32l4xx_hal_cortex.h"   #include "Sysclock_Config.h"       GPIO_InitTypeDef gpioInit; SAI_HandleTypeDef saiHandle; RCC_PeriphCLKInitTypeDef periphInit; DMA_HandleTypeDef hdmaInit;   uint8_t

I am trying to implement an TLS HTTPS server based on this HTTP Web Server sample:https://github.com/STMicroelectronics/x-cube-azrtos-h7/tree/main/Projects/STM32H735G-DK/Applications/NetXDuo/Nx_WebServerI have been trying to convert the above sample to TLS HTTPS from this example code functions from the same GIT hub:https://github.com/STMicroelectronics/x-cube-azrtos-h7/blob/main/Middlewares/ST/netxduo/samples/demo_netxduo_https.cBut I can't get the server to respond correctly from the clientHello, it responds with a short packet that should have been a serverHello. Using Wireshark to verify this.The HTTP sample works fine on the STM32H735G-DK as it should. I have also tried adapting the process described in Small Example System (TLS Web Server):https://docs.microsoft.com/en-us/azure/rtos/netx-duo/netx-secure-tls/chapter2The example above uses different functions than the STM32 hosted examples, but still have the same broken server response. I am sort of stuck now. I am posting th

Using HAL_SPI_Recieve(), SPI1 Master, 8-bit transfer, 3 consecutive bytes. At end of 24th clock pulse, the pin bounces up to a middle voltage and then decays to zero. Pull down resistor helps, but not enough. Screenshot of problem attached. How do I fix this? / Why is it happening?Note, also using SPI3 in an identical way and this does not happen. Only SPI1. (SPI2 is busy with other things and I can't really test whether this happens on SPI2.)

Hello,I am using Touchgfx v4.16.1 with an STM32F469 Discovery Board. I used Touchgfx Designer to generate two different applications for the Discovery Board. In both cases when I build the applications using the makefile, the external Flash file that is created is over 2 GB. I looked at the mapfile for each application and for both applications the memory used in the external flash space is much, much smaller. One of the external applications does not have any images in it so the external flash is only being used for fonts (approximately 400 bytes of memory). I removed the "-g" option from the makefile to try to eleminate the creation of debug symbols but that did not help.I can use Designer to load these applications onto the Discovery board and they run fine. I know the external flash file is much, much larger than the external flash on the Discovery board so it appears that only part of it is being loaded.I have used TGX previously and did not have this issue. The size of the extern

What could be the cause. I have checked the power circuitry. The rest of application still functions well. DMA, Timers, SPI, etc. Just network data is stalled. When temp goes down it resumes.

I have installed STM32CubeProgrammer 2.7.0 on Windows 10 and it works fine. but when iam trying to run STM32_Programmer_CLI.exe even as admin it open and close immediately. the same thing happens by openning the STM32Bootloader.batCould anyone tell me please how to solve this problem?RegardsDepo

Hi,We are using LIS3MDL in our application and current consumption in Power-Down mode is 0.2mA which is quite high but it should be 1uA as per the datasheet.Any suggestion on why I am unable to achieve 1uA level as mentioned in the data sheet?RegardsSiva

Hi to all,I want to configure DFU to create a USB bootloader for STM32F401RE (I need to understand it on this hardware for future implementation on different MCU). I have some questions.I configure CubeMX as the .ioc file attached.The main settings are:USBD_DFU_APP_DEFAULT_ADD = 0x08008000USBD_DFU_MEDIA Interface = @Internal Flash  /0x08000000/02*016Ka,02*016Kg,01*064Kg,03*128Kgmy main.c and usbd_dfu_if.c are attached.I installed en.stsw-stm32080.When I connect the STM32F401 to PC, Windows 10 recognize the device (enumerated as "STM32 DownLoad Firmware Update") but in DeFuSe Demo v3.0.6 I don't see any device available.1) What can be the problem ?Setting Application firmware.First I compile th application after change th linker lik this FLASH  (rx)  : ORIGIN = 0x8008000,  LENGTH = 512KThen I have to generate a .dfu file using "Dfu File manager":VID and PID are ok, I get them from CubeMX, but2) what do I put in Version and Target name?After t

Hello,I'm relatively new to embedded development and have been taking a driver development course that uses STM32CubeIDE. The the board I am using is STM32F407VG Discovery Kit. Basically, I have been creating multiple src main files to test out my driver code and have been using the Properties->C/C++ Build-> "Exclude resource from build" to decide which code to use.My issue started when I forgot to remove one of the src files and tried to build the project with 2 src files with a lot of overlapping code. After I removed one of them from the build, I started getting the follow message during attempts to build:12:37:34 **** Clean-only build of configuration Debug for project stm32f4xx_drivers ****make clean rm -rf *rm: can't remove 'stm32f4xx_drivers.elf': Permission deniedmake: [makefile:65: clean] Error 1 (ignored)When I try to interact with the stm32f4xx_drivers.elf file outside of the IDE, it appears that it is open somewhere. I am able to fix the problem temporarily by cl

I am receiving corrupt images from OV5640-STM32F4. This isn't regular, I get proper images of resolution 320x240 to 5MP, but occasionally I keep receiving corrupt images. The corrupt images are found in all resolution. By corrupt image I mean, sometimes the image color is wrong, sometimes the pixels are shifted, sometimes half the image is missing. I pick the image from SDRAM and transfer it over UART. I suspected it was because the DCMI is overflowing or some error. I set the FRAME COMPLETE, OVERRUN and ERROR interrupt of DCMI along with frame capture interrupt. When I debug even though I receive corrupt images, I don't get any error callbacks, I only get a FRAME capture call back. Does that mean DCMI is not the one causing the corrupt images? What might be the reason for obtaining random corrupt images?

hi, i wanna a stm32l072 datasheet CN version. no result on the st.cn

So I am using STM32f769 Disco board, first I use template project from TouchGFX Designer and so far it is good. But then I realize it is using framebuffer located on external SRAM address 0xC0000000. But I want to change the location to internal RAM e.g. defined as array in the code like:uint16_t framebuffer[widht*height].How should I do this?
