Solved

I started using STM32CubeMX, Atollic TrueStudio and the ST-Link Utility about 7 years ago and just recently, downloaded the latest STM32CubeIDE which does it all. Since then I noticed there are no files in the Drivers and Middlewares subdirectories although the project folder in the IDE shows the files. Not that I would want to modify those files, but just curious as to why I don't see them outside of the IDE.

Modular Switch Board Features:-The ESP32-S3 acts as a master module to drive the STM32 G031K8 slave slots.Slave slots can be plugged into the switchboard frame.The master and slave communicate over the I2C bus.The master controls the I2C slave slots by sending commands over I2C frames.The master always remains powered on.Both the master and slaves are powered by a common 3.3V supply.Slaves are mobile and can be plugged in or unplugged from the slots.Commands are sent to the master via a BLE app when a slave is inserted into a slot to initiate communication over I2C.Problem Statement:-Sometimes, a slave gets stuck on the I2C line.The slave holds the I2C line low, causing clock stretching.The master becomes unable to communicate, even after being reset using a dedicated reset button.I have a screenshot from a logic analyzer showing that my first slave successfully commissioned and received the address 0x60(slave address). However, when I add a second slave(second slave address 0x01), the

Hi Gfx Team,Could you consider adding an option to build code without running.Thanks

Hi,I am testing the USB HS Device CDC implemented from the CDC example (so using ST middlewares) and I notice a strange behavior while reading transfers of 512B.Internally, the function CDC_Receive_HS  file Appli/Src/usb_cdc_if.c has been adapted for a simple loopback as follows: static int8_t CDC_Receive_HS(uint8_t* Buf, uint32_t *Len) { /* USER CODE BEGIN 11 */ USBD_CDC_SetRxBuffer(&hUsbDeviceHS, &Buf[0]); USBD_CDC_ReceivePacket(&hUsbDeviceHS); SCB_CleanDCache_by_Addr((uint32_t *)Buf, *Len); CDC_Transmit_HS(Buf, *Len); return (USBD_OK); /* USER CODE END 11 */ } So basically, my testing program, based on libusb v1.0.27.11936, consists of consecutive bulk transfers to EP  #0x01 (bulk writing to STM32  CDC device) and from EP #0x81 (bulk reading from STM32 CDC device) during a time interval of 1 second.It works fine except for bulk transfers of 512B: in this case, the test results in approx. 50% of zero length bulk reads (0 B of data) so resul

Hello everyone.I am encountering a very strange issue with the STM32H7B0 using the J-Link to debug.I followed this tutorial to control the WS28B12 LED using Timer, PWM and DMA.I use the following function to transmit the PWM data. if (HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, address, 74) != HAL_OK) Error_Handler(); But here comes the strange thing:If i run the code, nothing happens, or lets say, the data doesn't get transmitted:But if i look at value of the address variable in the debugger before running the ...Start_DMA...:And then Resume the program it suddenly works:Why does this happen?Any help is appreciated

Hi, I try to update the firmware of an STM32L431 with another microcontroller. I use a UART interface to do that. As described in AN3155 §1, I send the 0x7F after managing the Boot0 and reset pins, and I wait for the 0x79 (Ack). But the STM32 answer: 0x28 0x40 0x00 0x01 0x00 0x14 0x74 0x29. My questions are: 1- Why is this bytes sequence and not the 0x79 as defined in AN3155? 2- Why does it answer without even parity as defined in AN3155? 3- I do not find the real timing sequence for managing the Boot0 pin, but after several tries, the STM32 answers only if I set to 0 the Boot0 pin and after sents the 0x7F. Is it the right sequence? 4- Is even parity mandatory for all commands or not? 5- In AN2606 page 337, USART3 connectes to PC11 and PC10, but we use the LQFP48 package and those pin are not available. Is the update with USART3 possible? Thanks for your answer and your help Best regards.

Hello everyone,I have recently started working on a custom board which has a STM32H733VG as the MCU. various interfaces including UART, I2C, SPI and sdmmc has been implementde hardware wise to provide links between MCU and other chips on the board.I was able to write to an SD card however when i want to read or right from other chips (external RTC (ISL12057), GPS module(MAX-M10M), ...) using I2C or UART interfaces, i get nothing.

We are having an unusual issue where we are failing emissions at 67.8Mhz or the 5th harmonic of the NFC frequency.  We are also close to the limit for the 3rd and 4th harmonic as well.  It is unusual because it does not fail in all operating modes.  It is failing only when our sensors (devices being charged via NFC) are fully charged, so they are not "taking in" energy anymore.  The specific standard for which we are failing is CISPR11B (graph below).   Below is a schematic of our circuit for the ST25R3916: Below is a schematic of the matching circuit and PCB coil antenna: We are trying to understand why the failure only occurs when it appears that the sensors are no longer taking charge. Any help would be appreciated!    

I am having an issue adding a bitmap into my project, its ID doesn't seem to get added into the bitmap database, but in debugging this I noticed that there is a bunch of info from a bunch of bitmaps that got deleted from the project long ago.I go into images, hit +, point the file picker at my .png file, add it in, looks great, put in a screen, looks great. Generate code, compile the code, compiler can't resolve the symbol for the bitmap ID. Grr.Maybe I just don't understand how these files work, but they do say that I should not edit them since they are generated by imageconverter. I expect that the database is borked, but if I delete it, and generate code, that makes a bigger mess. Apparently there is a trick that I don't know.Okay, how do I fire up imageconverter so that my bitmap gets an ID and the old stuff gets deleted?(4.24.1)

helloI need to interface about 20 small package inertial sensor via SPI and my MCU doesn't have enough GPIO for the chip selects so I'm looking for a module that can be daisy chained via SPI however I didn't find anything in the datasheets that indicate if these devices are compatible or how to do it.can anyone tell me if the LSM6DSOX is compatible or if not if there is a module with about the same capabilities that is compatible??best regards

Hello,  I am using the STM32H573RIV6 for my project and would like to use the USB interface. However, according to the datasheet, the VDDUSB pin is not available for the VFQFPN68 package. Does this mean the USB feature is not available for the STM32H573RIV6? This is not specifically mentioned in the datasheet. Regards, Harsha

Hello,I’m using the STEVAL-STWIN KT1B to log data. I flashed HSDatalog onto it and used the ST BLE Sensor Classic iOS app to log data and save it to an SD card.After acquisition, when I check the AcquisitionInfo.json file, I notice that "start_time" and "end_time" are always empty. I’d like to know how to automatically set "start_time" to the current timestamp when I press the Start button to begin logging.In the iOS app, I tried going to Settings → Nucleo Settings → Set node time and clicked to synchronize the mobile and node time. A window pops up saying "Sync Time - Sync Done", but after logging, "start_time" is still empty.Is there something I’m missing?Thanks!Best, Anthony 

Hi!I'm having a hard time trying to figure out the pinout from the datasheet for the M24M02E-F Eeprom.I plan to use the WLCSP5 package but the package information chapter and the pin description chapter paints two completely different pictures and I don't know which one to use. The pin indicator are in opposite sides. I suppose the package information is the most correct one but if I use that, how are the pins situated then? Simply just mirrored from the pin description image?Unfortunately I'm not alllowed to upload images but this is the datasheet:https://www.st.com/resource/en/datasheet/m24m02e-f.pdfPackage information is at page 44, chapter 10.4Pin description is at page 3, figure 3. Thank you

Hello,I am new to the STM32N657x0H3Q MCU and trying to generate code from latest CubeMX with the following peripherals enabled:UARTEthernetDCMIUSBNon-secure region onlyHowever, after generating the code and compiling it in Keli, I am encountering multiple errors. Additionally, CubeMX shows a warning:"  - Generating AppNS project without AppS, compilation errors maybe generated."I am trying to understand why this issue occurs.Is there a strict limitation in this MCU series that requires defining a secure region?If not, how can I properly generate code with only a non-secure region and avoid these errors?Also, I am planning to buy the STM32N6570-DK board for my project.thanks.....
