Hi everyone,I am working on a project using the STM32F7508-DK board, and I want to establish an Ethernet connection so that I can ping the board from my computer.I have a few questions regarding the setup:How should I physically connect the Ethernet cable? Should it go directly from the board to my laptop, or should it be connected through a router?What steps are required in STM32CubeIDE to configure the Ethernet interface properly?Are there any example projects or reference materials that could help me set up Ethernet communication on this board?Any guidance or advice would be greatly appreciated!Thank you in advance.

Hi,I'm currently experimenting with the decryption of custom data provisioned into the OBKeys storage with hardware encryption enabled.I've successfully provisioned the data without encryption and read it back intact.  With encryption enabled, I see that the data that I read back is different after every new provisioning/code change attempt which is as I expect, but I have not successfully decrypted it.  My code is based on code in low_level_obkeys.c from one of the Nucleo H533RE OEMiROT_Boot application examples.  Here's my code with error checking removed for compactness (no errors are returned, the code runs fine, just the output is not correct).  Note: temp_data contains the encrypted data exactly as read from the OBKeys region.  Once I get this working, I guess I'll just try decrypt directly from the OBKeys region. CRYP_HandleTypeDef hcryp = { 0U }; uint32_t a_aes_iv[4] = {0x8001D1CEU, 0xD1CED1CEU, 0xD1CE8001U, 0xCED1CED1U}; __HAL_RCC_SBS_CLK_ENABLE(

Hi, I am developing the board using the NUCLEO-F429ZI board CN7, CN8, CN9 and CN10 of ST, and I am looking for a product to upgrade to several surfaces such as FD CAN Port.According to ST's data, Nucleo-H743zi seems to be compatible except NC in CN9, but according to circuit diagram data, it doesn't seem to be compatible at all.What data should I look at and judge?I'm sharing the data I saw.Looking at the circuit diagram and pin map, it seems to be inconsistent.

I've created a TouchGFX project for an LTDC LCD with a H7a3 Nucleo board.  The project includes a static graph displayed on the LCD.  The project will compile, run and properly display the TouchGFX designed screen with the static graph. Next step would be to change the data on the graph from my custom code during run-time - possibly triggered from the button on the Nucleo.  However, I find a dead-end since main.c only has: #include "app_touchgfx.h" and cannot see a path to Model, Presenter or View classes.  I can't understand how any of the generated touchgfx code is referenced back to main.c. How do I call graph1.addpoint() from main()?  Indirectly or directly.  Or, maybe call from model:tick()??How is the touchGFX code able to compile without references to all the TouchGFX code from main.c?  More importantly, how to access the screen objects in code without any references to it from user code (main.c)??Are there any TouchGFX examples which

Hello,I'm currently in the process of creating a Custom Container top bar (Banner) with a clock (and other values like text with wildcard) that propagates through the screens. But I hit a dead end days ago and I cannot find the solution.Step 1: The fake hardware sets the timeStep 2: I propagate it to the modelStep 3: I propagate it to the presenter of the first screenStep 4 : I propagate it to the custom container Banner present on all my screens. → That's where I have my problem.The problem:The clock updates to the time I set in my Hardware for a second, then the next second (60 ticks), it is set to 00:00:01 (first second passed) and when I change screen, the clock propagates as I want to but with the basis of the first screen aka 00:00:01.I've based the application mainly on this ST post and glanced info in other posts but I can't manage to make my app work : https://community.st.com/s/question/0D50X0000C5SiHjSQK/where-is-code-editor-in-touchgfx-also-where-is-output-window-to-know-er

Hello everyone!I’m developing a device that will include an NFC Tag, and I’ve chosen the ST25DV64KC. This Tag needs to be mounted on a case and communicate with the "mainboard" of my project via I²C. Therefore, I’m working on a small circuit that will allow the Tag to be placed on the case and connected to my main circuit (which features an ST microcontroller and additional components).I’ve already designed the circuit for the ST25DV64KC, but now I need to develop the PCB antenna. For its dimensions, I’m referencing the application notes AN2972 and AN5605, and I’m also using your NFC Inductance tool: https://eds.st.com/antenna/#/.Now, I have a few doubts:The tool provides the antenna’s inductance value at 13.56 MHz based on the dimensions I input. However, I assume that to achieve resonance at this frequency, I need to introduce a capacitor between the two antenna electrodes (AN0 and AN1), calculated to make the LC circuit resonate at 13.56 MHz, correct?Another doubt concerns placing t

Hi, I'm using the LoRaWAN end node example from the stm32cubewl v1.3.0. The board im using is the RAK3172 based on the stm32wle5ccu6 chip. The application i want to build reads data from a modbus using UART and sends it through lorawan. I have assigned UART1 in the platform settings for debugging in lorawan and UART2 for reading from modbus. When I tested both separately the work perfectly. However when I integrate both together, Lorawan still works and uart 1 works properly, however uart2 stops working. I connected a USB to ttl converted to uart2 to see the if it was sending data, it sends data till Lorawan process starts running after that it doesnt send any data.  I am mostly using the code that is in STM32Cube_FW_WL_V1.3.0\Projects\NUCLEO-WL55JC\Applications\LoRaWAN\LoRaWAN_End_Node. The only changes that I have made are to write a function to read from modbus in main.c and call that function in lora_app.c just below the line EnvSensors_Read(&sensor_data); Yet UA

  Hi ST Community, I am currently working with the STM32H7S7DK development board and am configuring the LAN LWIP stack using RMII for Ethernet communication. However, when I run the code, the system encounters a HardFault. I am using STM32CubeMX for code configuration and STM32CubeIDE as the debugging environment. I would appreciate any assistance or guidance regarding this issue. If anyone has a basic project setup for configuring LAN LWIP with RMII on the STM32H7S7DK, it would be extremely helpful if you could share it with me. This would allow me to better understand what might be causing the HardFault. Thank you in advance for your help!

Hello, I have a question for NFC R/W mode (read/write EEPROM with ST25DV16K)tag : ST25DV16K - Nfc tag 4 clickreader : STM32 + X-Nucleo_Nfc08a11. When writing data to the ST25DV16K board via RF, how long does it take to read the data via I2C?2. It takes 5ms to write 1Block data with RF as shown in DataSheet. Is the writing time 5ms? Or does it mean that I should read it after 5ms of writing? Thank you!!!  

HII am using the STM32G474 MCU and ran into a problem with my code stopping execution.In my application, I have a level 0 priority interrupt that takes 1.34us to execute that occurs once every 6.66us.  In the final code, I will need 3 of these running, 1 every 2.2us (still leaving about 37% of the MCU bandwidth for other tasks).When I have 2 of these interrupts every 6.66us, all seems to work fine, but when I add a third, my code stops executing.  After a lot of debugging, I have found that my code is stuck at the following line of code:  ATOMIC_SET_BIT(huart->Instance->CR3, USART_CR3_TXFTIE);  in the HAL_UART_Transmit_IT() function.  Normally, when writing low level interrupt handlers for serial I/O, when I need to change the UART interrupt flags, I would disable interrupts make the change then enable the interrupts again.  Doing that, it is very clearly safe for a single core MCUs like the STM32G474.  However, when I examined the STM driv

Hey Community!I am trying to build a BMS for a 333V Battery using AEK-MCU-C4MLIT1 as the Master MCU, AEK-COM-ISOSPI1 as the translator and multiple AEK-POW-BMS63EN boards in a daisy chain.Although there are various examples provided in the SPC5Studio that one can use to get started with the BMS System. However, I am still finding it difficult to use the API functions effectively. I feel that although there are a lot of functions available in the API, their definitions are still absent in the documentation. Is there any other documentation which one can read to understand the data structures and different functions present in the API for the AEK-POW-BMS63EN?Thanks,Vipul

Hello,I would like to use the BLE_p2pServer_ota example with the STM32WBA55CG as a template for a project. Since I do not have an LSE available here, I would like to use the LSI. Which settings (defines) do I have to change?If I use the LSI with 32,000kHz, the advertising works, but I cannot establish a connection.

Dear Members,Is there any guidelines to select the values or size of three parameters in STM32cubeMX, middleware (USB device, CDC) to achieve the highest speed on CDC? I am using STM32L4P5VGT. My application streams the sensor data to the Laptop using USB CDC class, once powered on.To understand the question more in detail, I attached my current settings, are acceptable or can be optimised by reduction or increase, same time, need to avoid wastage of RAM also, so it can be used for other purposes if I am using too much.Regards 

Hi there, I am designing a product using an STM32H7RS-series MCU, and am looking for some clarification about the operation of the HSE oscillator. I see the H7RS has the option of an "analog" external oscillator in HSE bypass, in addition to the usual "digital" HSE bypass of previous products, and I am very interested in using that analog mode to use a lower voltage clipped sinewave output external oscillator, such as an NDK NT2016SE. My question is do I need anything in series between the STM32H7RS OSC_IN pin and the output pin of the analog (clipped-sine in this case) TCXO? I would assume I'm not supposed to use a series capacitor like the datasheets of these oscillators tend to show, because the STM32H7RS appears to be looking for a DC-biased signal, but before I make a board with no provision for such an inline passive and find out it doesn't work I figured I should double check here. Thanks!

Hi, to whom it may be concerned,I have a question about how to debug. I recently moved my successed project from stm32u585ci without smps with QFN to this lower mass and lower power consumption package, stm32u585ciy6qtr. This is my first time doing smps, and I think I wrongly connected the vss_smps directly to one of the vss. And I did not put extra 0.1uf caps for VDD_11, only those 2.2uf.  Because of the fabrication limits, we only have two layers of FlexPCB.I can see that the I2C2 and I2C3 work well, but ONLY I2C1 is blocked when the core is doing the computing work, and the ramp-up time is more than 1000ns in the oscilloscope. Even after we used a very small (<300ohm) value pull-up resistor and closely connected to the i2c1 pin area, the I2C1 still has a very high ramp-up time (fast mode) and will be blocked by core computing. However, the I2C1 can send out data by DMA. Then, I tried reconnecting the VLX_SMPS, VDD_SMPS, and VSS_SMPS to VSS/GND and connecting those two V
