Hello, i have a problem with my spi communication i don't recieve the information from the slave to the master Master configuration :Slave configuration : I want to receive how many time my led blink and i want to write it on my lcd screen. But everytime is printing 0.

Hi, I use the STM32F429I-DISC1 board with STM32CubeIDE 1.7.0.I can compile the project.But I upgraded the IDE to Rev 1.14.1.I cannot compile the project. It occurred a lot of error.What are different between STM32CubeIDE Rev 1.7.0 and Rev 1.14.1?Must I setup something before using STM32CubeIDE Rev 1.14.1? Thank you

Hi,Can somebody please explain what the "Flash memory endurance" value in the datasheet means? The max number of overall writes to the flash page or the max number of writes in the particular "cell" inside the page?Simple context:Let's say that the MCU has a page size of 2kB, a write granularity of 8bytes (64 bits, the "cell" - 256 of them in the page), and endurance in the datasheet 10k.The application writes from the beginning of the page toward the end. Reaching the end, rollover happens, the page is erased, and the same cycle repeats.How many application cycles are needed to reach the endurance value from the datasheet, 10k or 10k/256?Best Regards,Krunoslav

I migrated a project from STM32CubeMX 6.3.0 to STM32CubeMX 6.10.0.  It didn't boot anymore.There was this interesting diff to the linker script: ** Abstract : Linker script for STM32L452VCIx series -** 256Kbytes FLASH and 160Kbytes RAM +** 256Kbytes FLASH and 192Kbytes RAM MEMORY { -RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K +RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 160K RAM2 (xrw) : ORIGIN = 0x10000000, LENGTH = 32K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 256K }When did the STM32L452 get 192kB of SRAM?  This is wrong.  It's 160 kB.  The RAM region should just be 128K.  This puts the stack past the end of the real memory.

HiI m currently implementing a project using  MC Workbench software. There is a DAC Functionality subblock in the COntrol Unit block.  Can you tell me what is this block and why it uses two mcu pins as DAC ? For users which designing a custom board,  what should they do with these pins ?Thank you 

Hi, I am having some problems with my inplementation.Here is my scenary: + I am using a STEVAL-SAMARTAG1 with one shot mode example code, as my T5T tag. + I am using a NUCLEO-F722ZE board with x-nucleo-nfc03a1 as my NFC reader. My first problem is that when I ask x-nucleo-nfc03a1 which is it chip ID, I always get the string ‘NFC FS2JAST4’ with some characters wrong, for example 'N#C FS'.Then I try to detect the tag, and I get as an aswer: 0x0E 0x83 0x80 or 0x0E 0x87.I know 0x87 is invalid protocol, but I think I am initializing the reader correctly.

void StartDefaultTask(void const * argument) { /* USER CODE BEGIN 5 */ /* Infinite loop */ for(;;) { printf("Hello world!"); //HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_0); //HAL_Delay(1000); //osDelay(1); } /* USER CODE END 5 */ } Greetings! this is the code for printing hello world on the console of RTOS in stm32 cube IDE but I'm not able to see the results on the console is anything wrong here?? I have created a task to print hello world on the console

helloI used ST link to connect to stm32H743 and reported an error during the Programmer download process:"Error:ST-LINK error(DEV_TARGET_CMD_ERR)“.But,I used j-link to connect to stm32H743 and there were no errors during the stm32IDE download process.Can you provide some suggestions,thanks

Hi evryone,I've been trying to work on Zigbee communication for a while now, so far I've just learned how to read and write attributes. Now I'd like to try to learn how to use cluster Identify and groups, but I dont understand several thing, so I need help. For these cluster I'm working in Server.Identify Cluster (only IdentifyTime attribute)so i create my cluster, i allocate it as usual, i use the ZbZclIdentifyServerSetTime function and then i write in my attribute the value of the remaining time. what i don't understand is the part where in my code i'm going to receive the command that says "it's ok i can start the timer". i've seen that there's a start and stop structure that can be used via a callback, but i don't understand how to use it. Groups Cluster I don't really understand how to use this one.I suppose that my device will receive an order to say "I've been added to such and such a group", in which case, as above, how can I manage the reception of this order? How do

My machine is a 13th gen intel k chip with 32gb of ram. I have gigabit internet up and down. I have 2 samsung 990 NVMe pros. It has an rtx4080 My machine is perfect. Your software is ... not. I install windows 11 pro. I install CubeMX. After a minute of using it it decides to simply stop painting the screen anymore. Just like that. Bam! Unusable junk.I install windows 11 pro (again). I install CubeMX (again). After choosing new project (any of the 4 ways available to me) it hangs. Just an hourglass spinning into the abyss for eternity, whether I'm signed in or not.I'm starting to think ST can't hire people who can write reliable software. Why doesn't this work?There's no excuse for it. This is why I use zephyr, because ST's software is hot wet garbage. Think I'm wrong? Prove it by making this work on my machine. I'm so tired of wasting my time with your junk.

Hi, everyone I am Talha an Electronics student, I was recently working on making an oscilloscope using STM 32. I recently made a logic analyzer using stm 32 f103 RB. I now wanted to make a simple oscilloscope that simply displays the function generator's data. What I want is that I want to give an input signal using a simple function generator and display it on a serial analyzer. Now I don't get the problem as I tried to simply read the data and send it to USART and display it on the serial analyzer but unfortunately, there was a lot of noise, I don't get it what should I do, I have 2 STM 32 one with an ADC in it.It is a request to please help me If you can. I also need to integrate the output with a GUI I've designed using Flutter, but I would take care of it on my own.Help needed anyone with a similar experience please help.

Hi,Just yesterday on my H743VIT6 (rev. V ) on the running TFT : picture faded away...white screen.I just happened to look at the display , thinking ...ok, maybe one of the thin wires just broke now...TFT (small, 1,8" , ST7735 on 3,3V) connected /soldered about May 2022 , on SPI2 , at 48 Mbit . :)(Not touched/changed the wiring since then - so no static problem etc. possible.) Today i tried to fix the problem - but everything still connected !So took the scope to check the signals, beginning with reset ...all look ok, except SPI data !Here super slow rise time...ok, no useful signal for the TFT at 48Mb. (PC3_3 is sick ?)First check short to next pins - no, all free. Then impedance of pin unpowered : high, as cmos should be.Hmmm....try other pin: in Cube could choose PC1 as SPI2 data tx , so i changed to this and soldered the wire also here. (Soldering iron is antistatic.)Hey, TFT display ok, as before.But was the pin the problem - after 1 1/2 years running ?? So i set it as gpio ou

hi i have several questions about setting up STM32 chips as im trying to build a project which requires me to do so but ive encountered issues on my first step. im currently trying to set up my own MCU board using a STM32F722ZET6 144 however once i connect the st link it looses connection from the computer. i have used a pinout board which i then soldered wires to so it can be connected to a breadboard, the idea was not to create anything long term but to attempt to get it working. there are no issues with the reset, clock ect. parts of the circuit as it still occurs with them disconnected. for power im using a 3.3v regulator with 5v input which does create the correct power requirements with everything connected to what i believe to be correct, ive only setup the Vss and Vdd pins and not the power pins for ADC and USB. there are no shorts on the wires coming out, there appears to be none on the chip itself and i had help soldering by an engineer at work. i was planning to order some b

Tried implementing ADC conversion on STM32H563ZI Nucleo board. But, getting only a constant value like 66,67,68,69 in serial monitor(Tera term) irrespective of the given input even the i/p is unplugged getting the same values. Need a help to fix this. Thanks in advance!

Hello Community,We are selecting a high stability 12.288MHz HSE to clock our RTC on STM32G0 series MCUs.Kindly suggest if the HSE/32 which is 384kHz would be able to operate the RTC? I did not find any mentions of the maximum clock frequency for the RTC on STM32 MCUs. I understand the RTC has a prescaler, kindly direct me to the correct configurations.Clock Tree configuration using HSE with 12.288Mhz as clock input for the RTC on STM32G0Thank you!

Please let me know if I can use the Azure RTOS free with the STM32F767xx MCU and if it is free how can I use the same on my NUCLEO-F767ZI board? Please response as soon as possible. I need this to use the file system and also the ethernet/USB communication feature and other features. Can this RTOS be used for using all the wired/wireless communication peripherals available on the MCU? We need to make decisions based on this for our project. 

Hello.Three product packages are identified in the TS33's datasheet.Among these, the QFN-8 package has 5 NC pins. Is it okay to connect them to VIN or VOUT or GND?I couldn't find a additional explanation for the NC pin, so please check there is anything connected inside or it is a connection prohibition pin.Thank you.

Hello, I'm using Blue Pill Board With TMC2209 Stepper Driver To Control 3 Stepper motors. I've made a project using Arduino Mega and there were MobaTools & TMCStepper libraries available to Set Current and run multiple motors at once smoothly.  I wanted to know that, how can i do the same with Blue Pill Using STM32 Cube IDE ? Is there any special library to do the same stuff ?  Any help is appreciated. Please let me know if anyone have any answers.  

Hello, I would like to contact you because, following the code made on Keil uvision 5, I cannot get my interrupt to work.Objective of the code, turn on and off the LED (pb0) of the card with the button (pc13) on it itself.PCB Used : STM32F767ZI

Hello,We are using the USB HAL library on our custom board with an STM32H753VIT6. We have an external PHY chip (USB3300) and USB_OTG_HS. At the moment, we are using the USB to receive custom protobuf packets with a bandwidth at around 480 kbps. We have also written some additional overhead for our custom packets.Everything works mostly fine. However, after a second of running, some of our variables get corrupted. By looking at the build-analyzer in CubeIDE, I found that the RAM, namely the .bss section, was being set to garbage from 0x2400162c onwards. This was hUsbDeviceHS.ep_out[1].rem_length. I am not sure whether this variable is relevant to the problem or it is just a coincidence.I know that this could be from our own code somewhere that has a memory-leak, but I am wondering if this has been found before. I tried searching online but found nothing. Otherwise, are there any tips specific to STM32 to tracking down the cause?Thanks,
