Wich eval board mcu stm32 recommend me to learn and in the future can match with dsp.Regards 

I got a problem when building the project in the CubeIDE.According to the console, the function "function1" is not declared, but in the .hpp it is.I think the .cpp is not realizing that the .hpp is changing.Here, when I use the content assit, function1 doesnt show up. 

Hi All, Been reading and learning a lot about MCU's in general. I'm very very new to all of this so please bare with me.The board comes with STM32F427, and a custom .exe that can flash directly via USB-C. I've read about fake STM32's, and. I'm not sure if the MCU is genuine or not, but I'm adding the picture so someone can maybe help.The board comes with Ethernet, 3 USB-A, 1 USB-C (act as UART maybe?)The custom .exe can be flashed via USB-C after I put it in DFU mode I presume? (I hold the boot, it flashes blue to allow the flashing). I can click on flash, restore, or even backup basic configs.I would like to duplicate or retrieve the firmware so I can test it in another board. I tried STM32Cube, ESPtools, and many others, but it doesn't seem to recognize any connectivity.Any help or guidance would be appreciate. Thanks.  

Hello I wanted to create a external loader for STM32F411CEU6 (WeAct Blackpill board) and W25Q64 flash memory chip. I did it based on the tutorial from youtube link: https://www.youtube.com/watch?v=KlG2doCkREM&t=1792s I the tutorial i found link to W25QXX libray. And after testing in a simple project writing and reading,i know the libray works, but when i compile the external loader and test it in debug mode, the SPI transmit return HAL_Busy status, only when i debug the external loader project.I tried to lower SPI speed but without success. Why the libray works in a simple project but in a external loader project no. I see no reason why the SPI_Transmit status is BUSY.Here is link to repo (external loader project): https://github.com/apaczenko1993/W25Q64_BLACKPILL-F411 Maybe someone has commpiled external loader for BlackPill Board with W25Q64 flash chip, or helps me to explan what is wrong? 

I got a problem when saving a TouchGFX project and open it with the CubeIDE.The first time I opened a proyect from TouchGFX with the CubeIDE, it looked like this.But then, when I do new proyects they look like this. I can't do anything and I tried uninstalling both programs and reinstalling them but It does nothing.I really need help. 

I am using STM3210C-EVAL board. It has a audio jack port. Datasheet says i can play audio but i couldn't find anything about audio input.My question is:Can i record audio using a 3.5mm jack microphone via this jack input? And does this jack port support I2S protocol?If not, what is the best way to get audio input?

How can I get the value from a textArea so I can compare it with this '-' character?

I am running CubeIDE on OSX (not sure if t hat makes a difference)In the pinout & configuration you can see that some of the configured items, for example ETH and USART1 have a little green triangle next to them, indicating what I believe is a conflict.  If I hover the mouse over the icon, in just the right place, it will show a popup, but, no matter what I do, after a second of being visible, the popup disappears again, so I do not get long enough to read what its telling me, thus cannot figure out what I am being told. Is CubeMX really this buggy/ Is there some other view I can look at that will give me information about these conflicts so I may try to resolve them?Sorry if this is a dumb question, its probably obvious if you know what you are doing.  Eclipse has always been terrible, and so far CubeIDE has not disappointed. On a less frustated note, I do have a Nucleo 144/ 429 board running with a blinkey example I managed to write and program to the boa

Hello,I'm getting the wildcard character '?' displayed for 3x Japanese characters, ノ今速.  All the other CJK characters in the texts are displayed fine, before and after these missing characters (so not a text field truncation).I've checked that all these characters exist in the CJK font for the typography.  I have defined the respective Unicode values 0x30CE, 0x4ECA, 0x901F in the wildcard ranges and pasted these characters into the wildcard characters for the typography.  I have deleted and regenerated the generated folder, but there is no difference in the output. There are also no warnings during code generation that a character is not in the font.The text translations specifying these characters are all defined as resources (not single use texts).  They are displayed using touchgfx::Unicode::UnicodeChar TXTBuffer[TXT_SIZE];(void)Unicode::snprintf(TXTBuffer, TXT_SIZE, "%s", touchgfx::TypedText(T_RESOURCE_NAME.getText());I've found they are displayed correctly

Hello,I'm currently working with an STM32 microcontroller, and I'm facing a challenge related to the internal Real-Time Clock (RTC). Specifically, whenever I attempt to set the date and time using the internal RTC, my system crashes. I've reviewed the code and checked for potential issues, but I haven't been able to identify the root cause. Has anyone in the STM32 community encountered a similar problem when configuring the internal RTC? If so, could you share any insights, potential reasons for this behavior, or troubleshooting steps that might help me resolve this issue? Your assistance would be greatly appreciated as I work to address this problem in my project.     Here my Set date and time function,"/*** @fn ErrorStatus RTC_SetTimeAndDate(void)* @brief Function to use Set date and time into Internal RTC** @return SUCCESS / ERROR*/ErrorStatus RTC_SetTimeAndDate(void){    RTC_TimeTypeDef sTime;    RTC_DateTypeDef sDate;   if(HAL_RTCE

Hi I have a stm32L433, and setup Uart1 for standard TX and RX with interrupt for both send and receive (9600N81 setup). I don't use any hardware handshake . Within the IRQ routine occasionally the USART_ISR_EOBF bit in the ISR is set , and I am not using smartcard mode , and the EOBIE bit is not set in the CR2 register.. I have the below , and even after its cleared it then keeps getting set and cant get any data. void USART1_IRQHandler(void){unsigned char data;if(USART1->ISR & USART_ISR_FE)USART1->ICR |= USART_ICR_FECF; if(USART1->ISR & USART_ISR_EOBF)USART1->ICR |= USART_ICR_EOBCF; if(USART1->ISR & USART_ISR_RXNE) //RX interupt{data=USART1->RDR;...  Many thanksScott 

I read and display the CPUID and REVID on my project.I see the difference between using an U575 chip vs. U5A5 chip (NUCLEO boards): U5A5: CPUID: 0x410FD214 REVID: 0x30016481 U575: CPUID: 0x410FD214 REVID: 0x20016482 OK, based on ARM Cortex-M33 documentation: the same CPUID makes sense (and it is the same on different boards): the 214 at the end means: CM33 (the 41 should be the vendor).But now I want to verify the REVID:I cannot find any information in the MCU reference manual, neither in the datasheetit looks like, the SCB->CPUID (and REVID) register content is not mentioned anymore in any document (as it was/is in "older" MCUs manuals)I want to check during runtime, on which MCU the code is running: "is it a U5A5 or a U575?"How to do? (or where to find how the REVID is coded and if it would tell me the target I am running on)I see the difference on different boards, via REVID. I want to verify with manuals, documentation if it is the expected one (telling me: "it is a U5

I am using HRTIM in my project such that the output TA1 of timer A generates a delayed pulse after the timer is triggered via the EEV1 input. I have two compare values defined in Advanced configuration mode: One to set the output high and the other to set it low con compare match.In my setup, the EEV1 is currently triggered every 100ms externally (I'm using a PWM output of another timer with a physical connection to the EEV1 input of my HRTIM timer).One of the requirements of my project is the ability to shut down the outputs of the HRTIM timer at any time and also the ability to restart it.As a test, put the following code in the main() function:   while (1) { HAL_HRTIM_SimpleOnePulseStart(&hhrtim, HRTIM_TIMERINDEX_TIMER_A, HRTIM_OUTPUT_TA1); HAL_Delay(300); HAL_HRTIM_SimpleOnePulseStop(&hhrtim, HRTIM_TIMERINDEX_TIMER_A, HRTIM_OUTPUT_TA1); HAL_Delay(300); }  The expectation was that this code would repeatedly start and stop pulse generation on the TA

Hi ST Community, I am trying to measure system voltage (Lead Acid Battery) using ADC input of STM32F030C8 (PB1). The system voltage can be between 9V and 13.5V () so I am using voltage divider (10k and 1k) to lower the voltage to the 0 - 3.3V range. I am using STM32 Cube IDE. I am making ADC measurements/checking voltage in every 100ms.The problem is I am getting huge fluctuations when reading the voltage. For example, I am getting values between ~11.8V and ~12.3V, when the system voltage is around 12.09V (checked with multimeter). I am not expecting to get exactly 12.09V, but 200 - 300mV offsets/errors are huge for me. I am calibrating the ADC channel before measurement but the error is same.Could you please help me to this issue? Thank you in advance    /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ***********************************************

Hi everybody,I'm trying to connect to the STM32H743IIT6 on my custom PCB via JTAG. It seems it responds, I traced it with a logic analyzer (attached). I'm not too knowledgeable with JTAG Protocol, but the 0x5253000 the H7 answers seems not to be the chip ID from the BSD file.Consequently, I cannot connect via STProgrammer or CubeIDE. I checked all VDD pins, they're all ok. BOOT0 pin is Ground, NRST is pulled high, VCAP pins are 1V. Pinning is correct.I tried it with STLINKV3SET and a SEGGER J-Link base with the same results. I also tried pulling NRST down before flashing with no result and I looked at the signals with an oscilloscope, they seem alright (attached). Does anyone have an idea? I am out of ideas of what to try. Thanks a lot in advance!

Hy guys, I want to be able to create a named file in an SD card based on how many files I have in the directory, per example: if I have only 1 file "file1", I'll create the next one as "file2". I searched the ff.h library, but didn't find anything that seemed usefull. Has anyone know any ideas I might implement to make it work? Also alternatively, is there a function that reads or compares the name of the file and then create another file with a different name?

Posted on March 30, 2017 at 18:49Hi, I'm using the cubeF4 to work on FATFS application and i'm searching for a function in FATFS library that can return the content of the SD Card: number of files and their names.  Thank you.

Hello, I am currently building an application for the STM32WL. Two processes need to run simultaneously, the first is offline, and just reads data from a sensor and stores it in SD memory. The second is sending a LoRaWAN up-link message every 10 minutes (battery health monitor data). I am basing my project on the LoRaWAN_End_Node_DualCore_CM0PLUS project. I can see that the subghz radio runs on the CM0Plus, but the LoRaWAN network middleware files are on the CM4.  In summary, I am wondering if it's possible to send an uplink message through the radio driver with the CM0 while reading data through I2C on the CM4. Is it possible to multitask like this? Sorry for the beginner question. 

Hi all,AbstractWe are developing our product based on STM32H7. We would like to use the HTTP server and Netconn to update the firmware for our product. We consider this method easy to use for customers more than Serial or USB. We have tried looking for some references but for now, we are having a lot of problems.QuesionIf you could answer any of those questions that could help us greatly!1. Do you have an example, reference, or tutorial of working to update firmware via web server stm32h7?2. Do you have any idea how to start?Thank you for taking the time to read this and to answer me!Regards

I'm working with an STM32F217 and I have a few timer channels setup as sync clocks to regulators (around 1.5 MHz). I'm checking to make sure my sync lines are actually using HSE as a reference clock by looking at the phase drift between my external oscillator output and an STM32 timer output on an oscilloscope. With the amount of drift I'm seeing it doesn't seem like the timers are referencing HSE. I'm confused though because bits 3:2 of RCC_CFGR say I'm referencing my external oscillator as my system clock.Here are the related register values:RCC->PLLCFGR = 0x24403c18RCC->CR = 0x30b6983RCC->CFGR = 0x940a

Hi all,We have an application of an electric heating boiler using BTA16 triacs to commute resistive loads of 13A (rms). The max. temperature in the triacs is around 70ºC-80ºC.We are studying the option of using the BTA20 triac instead of the BTA16 one to improve the reliability of the solution. Both use the same case. I have checked the curves "On-state rms current versus case temperature" in the data sheet of both references and the behaviour in terms of max. current supported with 70ºC-80ºC case temperature seems equivalent because the BTA20 max current starts to decrease from 70ºC on while the BTA16 starts to decrease from 85ºC on. The scale of the graphs (in the attached) does not allow me to confirm which one would support more current. Could you please help me with this?In addition, I have seen the maximum power dissipation versus on-state RMS current graphs. It seems than the BTA20 max power dissipation is higher than the one in BTA16. Does this mean that under the same environm

Hello everyone,I'm trying to detect some RFID tags with the STSW-ST25RU-SDK wich is give here.I try to detect some tags with the Gen2_Inventory() function but when the ST25RU3993 detect a tag, an interrupt turn on and after my external MCU go directly in the InfiniteLoop. I always enter in this infinite loop when i detect a tag.Someone can help me to debug my interrupt please ? Thank you !Paul
