I am trying to persuade an stm32F412 to provide Periodic PC sample packets.Reference manual RM0402 implies it is doable (Configure DWT as a PC sampler)The "Cortex-M4 Technical Reference Manual r0p0" says "You can configure the DWT to generate PC samples at defined intervals" and DWT registers are described in the ARMv7M Architecture Reference ManualThat reference manual contains what I thought were reasonable instructions.I can see the CYCCNT register changing value as expected.I have confirmed that ITM and DWT registers can be written to. I'm obviously missing something!The below code does generate ITM packets over the SWO interface of my stlink v2-mini e, picked up via openocd, so I believe that the serial and clock speeds are set correctly.   DBGMCU->CR |= DBGMCU_CR_TRACE_IOEN; CoreDebug->DEMCR |= CoreDebug_DEMCR_TRCENA_Msk; DWT->CYCCNT = 0; ITM->LAR = 0xC5ACCE55; // unlock the ITM registers ITM->TCR |= ITM_TCR_ITMENA_Msk; //

Hello everyone,I am developing a custom PCB and am having a problem while trying to flash the chip.Before delving further, I need to say that I have made a mistake with routing the JTAG traces to 10pin JTAG connector and may have burnt the chip. I tried to circumvent this by soldering a new chip and using external wires as made a new connector for JTAG 20 to 10pin adapter (https://www.adafruit.com/product/2094) which then connects to ST-LINK/V2:After this I would get TDI ERROR message. I tried every possible type of connection available on STM32 ST-LINK Utility and STM32CubeProgrammer. I only maybe haven't tried to lower down the frequency.I checked the connections made to the chip and everything seemed fine. Every power pin gets correct voltage and there are no short circuits. The power comes through 2 LDOs: 1 is 3.3V and the other is 5V and the power input to the board is 12.5V and around 70mA. The boot pin 1 is connected to ground.I do not know what to try n

Hi AllI have installed STM32 CubeMX on a Mac and I get the following error when trying to generate code:The Eclipse executable launcher was unable to locate its companion shared library.

Hi,I am using STM32G0B1RE with the ISM330IS sensor, I just want to understand the procedure of loading a program into the ISM330IS ISPU memory, after compiling my algorithm I have the SREC binary format,  what should I do next ? from what I understand I need to let the host device to load the program into the ISPU, so I am thinking of copying the SREC data into a buffer then loading the program to the ISPU program RAM, so on every power cycle the host needs to load the ISPU program before starting fetching data is that correct ? 

I am trying to work with the VL53L5CX Tof sensor. The following calls succeed.VL53L5CX_InitVL53L5CX_ReadIDVL53L5CX_Start However, the following call fails:     VL53L5CX_Result_t pResult;    VL53L5CX_ProfileConfig_t _profile;    _profile.RangingProfile = VL53L5CX_PROFILE_8x8_CONTINUOUS;    _profile.TimingBudget = 200;    _profile.Frequency = 1;    _profile.EnableAmbient = 1;    _profile.EnableSignal = 1;    auto status = VL53L5CX_ConfigProfile(&vl53l5cx_obj, &_profile);Especially, when the driver tries to set the resolution, the calls fails. Any idea why is it so?

Simple question:If i'm right the serial number returned by cat /sys/firmware/devicetree/base/serial-number is the UID from BSEC. Where is the code responsible for setting this value? I've seen the function get_board_serial in u-boot but it doesnt seem to be implement for the stm32mp1 board.

Hello everyone,I am currently experimenting with X-Cube-AI with a NUCLEO-G474 (because i get some weird errors with NUCLEO-N6 [N6 Post] ). I am trying to run a very simple network with the validation application. I have some Questions which i have not been able to answer myself regarding X-Cube-AI.I first tried to print something to my pc console. I used UART with the function HAL_UART_transmit. This works fine.Then i want to do the same with the X-CUBE-AI package in use. The first thing i see is that syscalls.c is removed from the core folder and moved into X-Cube-AI/app. In  app_x-cube-ai.c in MX_X_CUBE_AI_Process() ->aiValidationProcess() i found the function LC_PRINT which also uses HAL_UART_transmit. But i cant see nothing in my terminal.I am not sure what i did wrong. Can someone help with this problem?

Hello, I plan to make a 333V Battery using AEK-MCU-C4MLIT1 as the master, AEKSCOM-ISOSPIA as the translator and AEK-POW-BMS69EN as the slave BMS Boards.  So far, I have been using the Example "SPC58EC—AEK_POW_BMS63EN_SOC_Estimation_Single application for discovery" to connect the Master to a single slave and receive cell voltages and temperatures. That has worked well.  Now, the next step of the project is to connect the slaves in a daisy chain and get individual data. Since the battery modules are supposed to be connected in series, I can't connect the slave boards using the USB connection. Thus, I have only connected the ISOH & ISOL lines.  As per the support document, I can't directly use the same example when I have multiple slaves. I should use the following examples: "SPC58EC - AEK_POW_BMSWTX_SOC_Est_SingleAccess_CHAIN application for discovery" However, I am not able to get cell data from even a single slave if I use this example, even when I change the connec

Hi community, I understand that users can encrypt and sign firmware using STM32CubeProgrammer. My question is about the first stage bootloader provided by ST. From my limited reading, it seemed that this 1st stage ST bootloader is only encrypted but not signed. Is my understanding correct? If not, please can someone point to me the document describing how does ST do the 1st stage bootloader signing and where the verification key is programmed on the MCUs? Thanks, and best regards James  

Hello, first time poster.I recently got a few NUCLEO-WL55JC2's for a research project.but other than the standard examples, I am unable to compile a project that I either made using my own ioc, or the one in C:\Users\%username%\STM32Cube\Repository\STM32Cube_FW_WL_V1.3.1\Projects\NUCLEO-WL55JC\Applications\LoRaWAN\LoRaWAN_End_NodeWhen I use either of these, this is the error message I get in CubeIDE, when hitting build. ../Core/Inc/platform.h:45:10: fatal error: stm32wlxx_nucleo_radio.h: No such file or directory 45 | #include "stm32wlxx_nucleo_radio.h" | ^~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. arm-none-eabi-gcc "../Middlewares/Third_Party/LoRaWAN/Mac/Region/RegionBaseUS.c" -mcpu=cortex-m4 -std=gnu11 -g3 -DDEBUG -DCORE_CM4 -DUSE_HAL_DRIVER -DSTM32WL55xx -c -I../Core/Inc -I../LoRaWAN/App -I../LoRaWAN/Target -I../Drivers/STM32WLxx_HAL_Driver/Inc -I../Drivers/STM32WLxx_HAL_Driver/Inc/Legacy -I../Utilities/trace/adv_trace -I../Utilities/misc -I../Utilities/sequencer

Hi all,I recently purchased an STM32H723VGT6 breakout board [https://github.com/WeActStudio/WeActStudio.MiniSTM32H723] (not a NUCLEO) and a VL53L5CX sensor breakout from Pololu [https://www.pololu.com/product/3417], and, as I'm a beginner and struggling to navigate all the literature as it relates to STM32, I was wondering if anyone here could give me a step-by-step guide on what documents I need to read in order to set up this custom hardware before I design a similar setup myself with an STM32H523 instead of an STM32H723.I've already went through the user manual, quite a few YouTube videos, and some more stuff, and I'm confused, since I can't seem to find documents on working with X-CUBE-TOF1 and custom hardware.The main issue I have is the fact that I only want just that two pin I2C connection between the MCU and the sensor and nothing else due to the space constraints of my upcoming custom design [PB10 = SCL, PB11 = SDA]. Therefore, I have done the same in the prototype with the of

I am using the STM32WB15CC and encountered an issue when my program exceeded 112KB (0x1C000), causing the flashing process to fail. I noticed that the memory region starting from 0x0801C000 is set as a secure flash area.I would like to know if it is possible to modify this secure flash area. If so, could you please provide guidance on how to make the necessary modifications?

Good day,I've been working on getting an external adc on the nucleo H755ziq to work at max speed. The adc can reach up to 1 million samples a second with a clock cycle time of 10ns. Problem is that it's only seeming to go at a speed of 60ns per clock cycle. Spi is set at 200mhz with a /2 prescaler on an external 48mhz crystal. Any idea why it's getting this 60ns speed instead of 10ns? Ive set the GPIO for spi to very high speed as well encase that was the issue.

Hi,I am developing AC-DC flyback with HVLED815PF controller.Using application note AN4350 I managed to have a CV output for 6W max.At high load, everythings good and functioned as expected.I got 25% iTHD and 0.96 PF.However at 2W and below its suddently getting worse.After checking it out, it turns out the controller operating in burst mode and normal mode alternately.I have checked all pins and did not found anything out of the ordinary, except that COMP pin is below 1V that triggers this burst mode operation which is my questionWhat could be the reason for this? and how to mitigate this?Its too early to enter burst mode at just 30% load. 

Hi,I'm trying to get the FTM examples from the STSW-ST25R-LIB to work on a ST25R3916.I am using the following hardware:-Mikroe NFC 4 Click Board with a ST25R3916-STEVAL-25R3916B (I only use the reader/antenna board STEVAL-D25R3916B without the Mcu board)-Nucleo L476RG microcontroller board (as it is the one used in the sample projects from the library)On the software side I am using the FTM examples from the X-NUCLEO-NFC06A1 (for 3916 on Mikroe board) and X-NUCLEO-NFC08A1 (for 3916B on Steval board) folders in the lib. The programs seem to be identical, only the global definition for the HW/reader selection is different.When I use the NFC08A1 program with the Steval, the reader works fine. But when I use the NFC06A1 example with the Mikroe board it doesn't work. When I try to read the chip ID in the initialisation process, it always reads zero. I have checked this interaction with a logic analyser in both examples and have attached the screenshots. I have tried both SW examples on

Hello! I'm looking for a BSDL file for the SPC560D40L1BxE0.Is it available somewhere?Kinds regardsJacob

In my setup, I’m using Comparator 6 (COMP6) on the STM32G474 microcontroller. The non-inverting input of the comparator is connected to a burden resistor from a current transformer, which measures current flow. The inverting input is tied to a fixed 1.5V reference created by a voltage divider. The goal is for the comparator to disable all PWM signals (generated by HRTIM TimerA) when the burden resistor voltage reaches 1.5V, indicating an overcurrent condition (e.g., 10A).Issue: Despite the burden resistor voltage hitting 1.5V at 10A, the comparator does not trigger, and the PWM remains active.

Best SPI Routing Method for Double-Sided 16×128 LED Matrix Using STP24DP05Project OverviewI am designing a double-sided 16×128 RGB LED matrix display using STP24DP05 LED drivers. The LED drivers are controlled using a single SPI bus from the MCU. Since the display consists of both a front and back panel, each panel consist of 16 STP24DP05 LED driver. I am considering two different approaches for routing the SPI and error signals and would like recommendations on the best solution.Approach 1: Split SPI and Error Signals Using BuffersIn this approach, I use buffer ICs (74LV244) to split the SPI bus and drive both the front and back panels independently. Additionally, the error signal (ERR) from the STP24DP05 drivers is also split and handled separately for each panel. Each panel consist with 16 LED driver. SPI Control: The SCK, MOSI, MOSI and CS signals are buffered separately for the front and back panels.MCU Control: The MCU enables/disables the SPI buffers using GPIOs, ensuring t

I'm trying my hand at a LoRa project and settled on using the STM32WLE5JC chip on Seeed studio's Wio-E5 module. I've read through the bootloader manual and Seeed studio has their own set of instructions for wiping their pre-existing code which I have gone through, but my question is in regards to after I have successfully flashed code similar to the ping-pong examples in subGHz. Specifically, is it possible to upload code using an ST-Link without access to the BOOT pin?For reference, the module gives access to SWDIO, SWCLK, and NJRST, which I have broken out these pins along with GND and PWR, but the BOOT pin is not accessible. In my past experience using STM32, I flashed through UART which did require the bootloader and hence boot pins were the easiest way to go. From what I have read online, it seems that flashing through ST-Link doesn't require the system to be put into bootmode but would appreciate some confirmation on this. Seeed's factory firmware appears to have made a different

I was looking at STM32N6, and it says it has 1G networking. Problem is, chip used is 100M. So how can they say that development kit supports 1G ?LAN8742A-CZ-TR chip used inside both devkits:Same goes to HR timer, it says on datasheet, it does support high resurrection timer, while no mention anywhere about itIs there nay more information regarding timer and does devkit support 1G ? I was hoping it could, since I could make IP camera or something similar.
