Is there anyway to increase the size of the icons in the top menu bar in the IDE?I am 70 now and my eyesight needs a wake-up here :)

Hi All,I've just been watching an ST tutorial video on how to implement  bare-metal Device CDC USB  on an STM32U3.During the video, the lecturer says that the code is available within the workshop download. No link is provided to the workshop code....Does anyone know where I can find it? This is the video in question : https://youtu.be/m8ph9JIY5QE?list=PLTJzs51NlEIAHFfePhKJPsnWvT5XidJuU&t=1164Any help would be appreciated.CheersMichael 

Hello ,I am working on a project with the STM32L562CET6 microcontroller and have encountered an issue with the timer interrupt callback function.   1. I configured TIM6 as the clock source for the microcontroller. Consequently, the HAL_TIM_PeriodElapsedCallback() function is automatically triggered whenever the TIM6 interrupt occurs.   2. Now, I have configured TIM2 for a different purpose, but I noticed that when the TIM2 interrupt occurs, the same HAL_TIM_PeriodElapsedCallback() is triggered.Since the HAL_TIM_PeriodElapsedCallback() is defined with the weak attribute, I understand that I can redefine it in my user code. However, this causes conflicts when multiple timers (like TIM6 and TIM2) trigger this callback.Questions:  1. Is there a way to alias or redirect the HAL_TIM_PeriodElapsedCallback() to separate functions for different timers (e.g., one for TIM6 and another for TIM2)?  2. Is there any other specific callback function available for timers i

Hi All,    I want to do something very basic, but somehow cannot manage to do it. What happens if you have a PWM signal on an IO Pin, generated by a timer, and you disable the timer?  What happens to the physical IO Pin ? Is it stuck at the state where it was when you disabled it ?, Does it go Low ? Or High. The Idle state of the Timer is Low, and the On state High.    Thanks,  DJ 

I am trying to learn how to program a STM32 micro-controller, specifically a STM32C593. The thing is according to its datasheet it has Ethernet functionality, bit it is missing in the peripheral list inside STM32CUBEMX2 IDE. 

Hello ST Community team,I would like to report a possible inconsistency in the STM32 MCU Portfolio Selector regarding Ethernet filtering for the STM32C5 series.While selecting MCUs using the Portfolio Selector, I filtered devices through:- EthernetThe reference STM32C593CET6 appears as supporting Ethernet functionality. However, according to DS15136 (Table 1), this specific MCU does not include the Ethernet peripheral.This may create confusion for developers, especially since the STM32C5 family is still relatively new and many users rely on the Portfolio Selector during early device selection.Could you please review and correct this behavior.Ps: more details available on this post. Best Regards.II

Hello!I am having trouble verifying NPU operation on the NUCLEO-N657X0-Q board.I am trying to test a simple INT8 FNN (Feed-Forward Neural Network) using an ONNX model. The project was generated via X-CUBE-AI within CubeMX. I have configured the AXI and Clock settings (CPU: 600MHz, NPU: 800MHz, NPU AXI: 800MHz) and, given the model's simplicity, I set it to use internal SRAM only.While the code execution seems to flow correctly without errors, I noticed that the output values are not being updated. The output buffer remains unchanged, or in some cases, still holds values that look like the input data. It seems the NPU's computation results are not being written back to the memory correctly.I would greatly appreciate any advice or suggestions, even if they aren't complete solutions!Environment Versions:CubeIDE: 2.1.1CubeMX: 6.16.1CubeProgrammer: 2.22.0ST Edge AI: 4.0ST-LINK: V3J17M10I have attached one of the project files I’ve been testing for your reference. Thank you always for your s

Hello everyone,I am currently working with the Aliro software expansion for STM32Cube using the new STEVAL-ALOCKCB board (Aliro access control reference design based on STM32WBA65RI, ST25R300, and STSAFE-A120).Both the hardware and software are in their original, unmodified state from ST. The nfc12ble project builds successfully without any issues.However, I am encountering a consistent problem:the function CryptoInit() always returns false.From debugging, I can see that the failure originates from the CheckReaderPubK() function, which internally calls isValidProvisioning(). This function also returns false, causing the entire initialization to fail.It seems that the provisioning structure is not considered valid. In particular:The check prov->isValid == DEVICE_PROVISIONING_STRUCT_IS_VALID fails.DEVICE_PROVISIONING_STRUCT_IS_VALID is defined as 0xA5A55A5A (decimal: 2779077210).However, the actual value read from flash appears to be different (e.g., 0xFFFFFFFF), which suggests that t

Dear STMicroelectronics Community / Support Team,I hope you are doing well.I am currently working with the STM32N6 Discovery Kit and noticed that it uses an external Octal NOR flash device with the part number MX66UW1G45G. However, I have been unable to locate a public datasheet for this exact component.I was able to find datasheets for similar parts such as MX66U1G45G and MX66UM1G45G, but not for the “UW” variant used on the board. This has led to some confusion regarding the exact specifications, supported features, and command set of the device.I would appreciate your guidance on the following points:Is MX66UW1G45G a custom or internal part number used specifically for STM32 evaluation boards?Is there a publicly available datasheet for this device, or can it be shared upon request?Can MX66UM1G45G (or another publicly documented part) be considered a fully compatible equivalent for development purposes?Are there any specific differences (e.g., command set, timing, interface behavior)

Hello, I am working on an SNMP implementation using STM32H753ZI with the LwIP Ethernet stack. Currently, SNMP v1 is working successfully, including trap generation and reception testing using Net-SNMP tools. I am able to send enterprise-specific traps from the STM32 device. Below is the trap code currently working for SNMP v1: void send_temp_fault_trap(void) { static const u32_t enterprise_oid_arr[] = {1,3,6,1,4,1,50598}; struct snmp_obj_id enterprise_oid; enterprise_oid.len = LWIP_ARRAYSIZE(enterprise_oid_arr); memcpy(enterprise_oid.id,enterprise_oid_arr,sizeof(enterprise_oid_arr)); ip_addr_t dst; IP4_ADDR(&dst, 192,168,0,255); snmp_trap_dst_ip_set(0, &dst); snmp_trap_dst_enable(0, 1); static const u32_t msg_oid_arr[] = { 1,3,6,1,4,1,50898,10 }; static struct snmp_varbind vb; static struct snmp_obj_id msg_oid; static char msg[] = "System Working"; msg_oid.len = LWIP_ARRAYSIZE(msg_oid_arr); memcpy(msg_oid.id,msg_oid_arr,sizeof(msg_oid_arr)); vb.next = NULL

Hello everyone,I have encountered a strange issue with my UART transmission function on an STM32 microcontroller operating in Half-Duplex Open-Drain mode.Currently, the function works perfectly fine without checking the TC flag. However, when I add a check to wait for the transmission completion at the end of the function, my logic analyzer shows completely garbled bytes (corrupted data).Here is the code that works perfectly (without the TC check):void send_array(uint8_t *arr, uint8_t size) { /* Receiver disable */ USART3->CR1 &= ~(CR1_RE); for (int i = 0; i < size; i++) { /* Wait until Transmit data register is empty */ while(!(USART3->SR & SR_TXE)){} /* Send byte */ USART3->DR = arr[i]; } /* Receiver enable */ USART3->CR1 |= CR1_RE; }And here is the modification that breaks the transmission and leads to garbled bytes on the analyzer:void send_array(uint8_t *arr, uint8_t size) { /* Receiver disable */ USART3->CR1 &= ~(CR1_RE); for (int i

Hi,I am using the STM32F407VET6 chip to simulate the SENT protocol. I have encountered some issues and would appreciate it if professionals in the forum could provide some answers.1.Since the SENT protocol signal needs to change the output waveform based on the transmitted data, I attempted to use the TIM BURST feature of the chip to simulate the SENT signal. I am configuring it using STM32CubeMX software. Below are the relevant configurations:   2.The SENT protocol specifies that one tick is 3μs to 10μs. I initially set the PWM to a period of 3μs with a 50% duty cycle square wave and output it. Since I am not very familiar with the TIM BURST feature, I first used the HAL_TIM_DMABurst_WriteStart() function to attempt to modify the waveform originally output by the chip. I plan to change the waveform to the synchronization signal in the SENT protocol, which involves outputting 5 ticks of low-level signal and 51 ticks of high-level signal.Initial PWM output waveform:The de

Hello, I am looking to use the LSM6DS032 accelerometer + gyroscope in a project, I intend to interface it with an MCU via I2C. I am wondering if it is possible to program the embedded finite state machines in the accelerometer using only I2C and writing to registers, and if there are any guides or application notes on how this can be done?

What is the recommended procedure for adding source files (e.g. source1.c and source1.h) to a STM32CubeIDE project generated by TouchGFX? I assume I add them to one of the 'Core' directories, but I see multiple Core directories (root\STM32CubeIDE\CM7\Application\User\Core and root\CM7\Core). I see that adding my .h manually to root\CM7\Core\Inc works fine for the .h, but the IDE doesn't automatically pick up the .c if I place it in the corresponding root\CM7\Core\Src. If I place the .c in root\STM32CubeIDE\CM7\Application\User\Core, the .c file is accessible via the IDE, but the .h file is not found during compile.What is the proper procedure for adding new user C source files?  My STM32CubeIDE is 2.1.1 and TouchGFX is 4.26.1. I'm targeting a Riverdi board with a STM32H7.
