Good day Folks,I am trying to get a simple program working on the STM32N6 Nucleo board, however when debugging an interruptoccurs causing the code just to get stuck in the Default Handler.I am not sure what interrupt is triggering it.This is most likely a 1 line fix, or some arbitrary setting I haven't found yet.Steps:1. Change Boot 1 jumper to VCC2. Connect USB, Red LED2 is On.3. Started a new STM32 project and used the Example Selector. Select and Build GPIO_IOToggle.  4. Make Debug profile and connect5. Wait until main() entered.6. Click Run.. No LED flashing so Pause debugger7. Resetting the Micro just freezes and the device never gets the first main() breakpoint. I was expecting it to return to Step 5.8. Pausing at that point just shows the device is at some address.9. We need to restart the debugger session from scratch: In summary, Pausing the Debugger on Step 6 shows its stuck. I don't believe it's anything related to XSPI3, as adding a handler for it, just makes

Hi,I've been trying to get a MicroSD card working with my H755 Nucleo for the last week. Tricky, isn't it?!I started with a SPI SD-card interface but gave up on that after about several days of pain. My focus now is on interfacing via SDIO, using the SDMMC peripheral on H7 and FATFS with FreeRTOS. I've tried both 1- and 4-bit mode.I have the card initialising OK in MX_SDMMC1_SD_Init(), but calls to f_mount() are failing in check_fs() (in ff.c) which returns FR_DISK_ERR (=4).I've tried multiple different cards.Interestingly I have been able to format a card, but it remains un-mountable, as well as when using an externally-formatted card.I came across https://community.st.com/t5/stm32cubemx-mcus/stm32h7-how-to-use-sdmmc-with-mdma/m-p/220163  which contains a useful PDF which aims to fill the holes in AN5200 (whoever wrote the section around Figure 14 "MDMA end of data configuration with STM32CubeMx" seems to have lost interest just as they got to the interesting and i

Driving DAC1 channel 1 with         HAL_DAC_Start(&hdac1, DAC_CHANNEL_1); ... while (1) { HAL_DAC_SetValue(&hdac1, DAC_CHANNEL_1, DAC_ALIGN_12B_R, 4095UL); HAL_Delay(100UL); HAL_DAC_SetValue(&hdac1, DAC_CHANNEL_1, DAC_ALIGN_12B_R, 0UL); HAL_Delay(100UL); }         to generate 5 Hz, 50% duty cycle, 0 - 2.5v. Amplitude as expected but frequency varies from 1 - 4s and duty cycle varies from 20 - 80%: not expected. DAC1 configured like DAC1 clocked at 65 MHz. When I step into HAL_DAC_SetValue() I see where the 0 - 4095 value is written to data register (12-bit, right-aligned). But sometimes after writing 4095 the output pin reads zero; and sometimes after writing zero the output pin reads 2.5v. I can't explain why this happens. DAC Instance following write looks like I am the only writer on the data register.

I am using the ADC on a Nucleo-L412KB board.   I am setting up the ADC for  single conversion once per second. I am getting digital values which are off, as though the Vref is up around 3.4 V.  I have an LM385 voltage reference as a source and have tried a precision bench supply (Power Designs 2005) and with either input, working the math backwards, it is as though Vref is about 100 mV off. I have read AN2834.  This is a simple "get acquainted" exercise, with the board right out of the box. Is there sometihng I could be overlooking?  Am I required to set up Vref?  Or is this handled by default with the HAL initialization? Clyde

Hello,I want to connect STM8S003 & ADXL345 (accelerometer) using SPI 3wire mode (lines ~CS, SCK & MOSI as single bidirectional data line).According to 'RM0016 Reference manual STM8S...', the register SPI_CR2 of STM8S has BDM (Bidirectional data mode enable) & BDOE bits (Input/Output enable in bidirectional mode).I expected to use these bits to control SPI 3 wire connection:SPI_CR2 =   <BDM=1 | BDOE=1 | SSI=1 | SSM=1 (Master)>   - to set STM8 MOSI as outputSPI_CR2 =   <BDM=1 | BDOE=0 | SSI=1 | SSM=1 (Master)>   - to set STM8 MOSI as inputTo exclude possible questions:1. ADXL345+ATmega8 was tested in 4wire & 3wire modes, all is OK.2. ADXL345+STM8S003 in 4wire mode works OK. For 3wire mode I've only disconnected line MISO in hardware.I also can control SPI_CR2 state, chnging it before SPI operations and write the processess using oscilloscope.Test:STM8S transmits 0x80 | 0x2C = 0xAC to ADXL345 then it tries to read the ans

Hello everybody.I have a STEVAL-FCU001V1 board and I would like to use the SPBTLE-RF BLE module included. I have read the board datasheet and it indicates that the module uses the SPI1 pins as an interface, but in the module datasheet there isn't a section for commands or registers, so I wonder how I can control and configure the module, I have found in some posts that it uses the HCI commands, it's correct?Any help will be appreciated. 

I have a NUCLEO-G491RE board connected to a PC running STM32CubeIDE v1.17.0. On first connection I was prompted to update the firmware on the board, which I did. On successful completion of the update I disconnected and reconnected the board, but the download failed with the attached message. I have tried several USB cables and also with and without an intermediate USB hub to eliminate these possibilities.What is the solution please?

I am having trouble receiving data with my Riverdi Display rvt70hssfwca0. I am not sure if it is a software or a hardware problem since when I was testing the RS485 I shorted pin 2 (Signal A - Non inverting) and Pin 1 (Vin - 24V). When debugging this is what I observed.Signal coming from Pin 2 of RS485 port is little over 1V instead of 3.3V while Pin 3 (Signal B -Inverting) is working fine at 3.3V.  When the device connected to the RS485 port replies back both signals (A and B) are at 3.3V. I believe D4 might be damaged because I could see a physical discrepancy on the casing (a little hole).At U2 the incoming signal and the outputting signals seem similar to what was observed at the RS485 connector port. (Outgoing A is ~1V, everything else is 3.3V) This is where I find the main suspect:The receiving signal observed from RO pin (going back to the MCU I suppose) are pulse-like (noise maybe) instead of the expected squared IO signal observed at the port.

Hi community :)  today for you I'm ShirleyIm using a STM32F411RE, a SIM7600G and a external eeprom 24LC1025.The SIM7600G will make requests to a web server where HEX files will be stored for the MCU firmware update. However, I noticed that initially, it sends 16 bytes of data, but at some point, it starts sending 8-byte data packets.Would there be any issue if I adjust this behavior by concatenating the data packets in groups of 16 so that I can receive them packet by packet through the SIM7600G? Then, after performing a checksum verification, I would write the data to the external memory, after that i would enter Bootloader mode and write the data to the Flash mem. Here's an example, in the highlighted line says that 8 bytes should be writen in address 08004190h and after that of the next 16 bytes, another 8 bytes should be writen in the same address, the leftover are stored in the next address.

Hello Community, I'm setting up a test with NetxDuo + MQTT over TLS (aka MQTTs, port 8883) on a STM32F429NIx.As far as i see from the example available it consider a scenario where the client verify the certs provided by the server with the supplied CA.This could work, but it's not mutual-tls, while I'm trying to have a mTLS (mutual-tls ) where also the client_cert and client_key are used.I see the tls_callback function specified in the nxd_mqtt_client_secure_connect have two NX_SECURE_X509_CERT * parameter. UINT tls_setup_callback(NXD_MQTT_CLIENT *client_pt, NX_SECURE_TLS_SESSION *TLS_session_ptr, NX_SECURE_X509_CERT *certificate_ptr, NX_SECURE_X509_CERT *trusted_certificate_ptr)  Always from the examples i see trusted_certificate_ptr is used for the CA, while the certificate_ptr for the cert received from the server.Then my question is: where i have to load the client certs? Have i misunderstood the certificate_ptr parameter so i have

Hello, this is the ECMF4-40A100N10(MIPI DSI ESD protection). I want to implement it in my design and I was wondering if it matters to connect your positive differential pair signals to D1+ and D2+ and negative to D-. Or can  acually flip them? So I connect my negative differential pair signals to D+ and positive to D-. That way I can route it much easier. Thanks

Hi!Does anyone know if there is a chance there will be a launch of a one-chip-solution for any of these MCU-series during 2025?What I mean is an MCU with large built-in FLASH + RAM preferably with a LQFP100/144-package (like the U5-series).We are prototyping an industry application for smaller product series. The potential extra MCU cost for a chip with large built-in memory would be marginal. We are much more interested in an easier PCB-design, lower PCB manufacturing costs and not to mention an easier hardware maintainability over time.Thanks in advance for any comments  

Hello, I am trying to debug an example code on a recently bought AEK-MCU-C4MLIT1 Evaluation Board via AEKSMCU-SPC5LNK using OpenOCD. I am fairly new to Embedded Systems and Eclipse Environment so I have just been following instructions.  And things don't seem as straightforward as STM32CubeIDE.... When I am trying to debug the board, I receive the following error on the console.  Open On-Chip Debugger 0.12.0+dev-00318-g0e98d766e (2023-05-17-15:52)Licensed under GNU GPL v2For bug reports, readhttp://openocd.org/doc/doxygen/bugs.htmlStarted by GNU MCU EclipseInfo : Listening on port 6666 for tcl connectionsInfo : Listening on port 4444 for telnet connectionsError: Debug Adapter has to be specified, see "adapter driver" command   Also, I am not sure whether the Board AEK-MCU-C4MLIT1 is alright or not. Should I expect some LEDs to be Switched ON on the board when I connect the usb or the 12V supply? I have attached the screenshots of my Debug Configuration.&nb

Hi!i have a question about the use of byte pool in threadX.in the App_ThreadX_Init(VOID *memory_ptr) i have the pointer to the byte pool is given like that:UINT App_ThreadX_Init(VOID *memory_ptr) { UINT ret = TX_SUCCESS; TX_BYTE_POOL *byte_pool = (TX_BYTE_POOL*)memory_ptr; and i'm using this pointer to allocate memory for thread, queue ecc . now i'm passing the pointer byte_pool to my threads like this:tx_byte_allocate(byte_pool,&pointer,CONSOLETHREAD_STACK_SIZE, TX_NO_WAIT); tx_thread_create(&threadConsole,"console_thread",console_thread_entry,(ULONG)byte_pool,pointer,CONSOLETHREAD_STACK_SIZE,15,15,1,TX_AUTO_START);and i want to use that pointer to allocate memory with tx_byte_allocate for sending via queue pointer to data structure instead of the actual dataexample:VOID *pointer; if(tx_byte_allocate(byte_pool,&pointer,(sizeof(paramRequest_t)), TX_NO_WAIT) == TX_SUCCESS) { ((paramRequest_t*)pointer)->startParamN = 0; ((paramRequest_t*)point

Hello,I am currently exploring the SPC5Studio IDE for developing applications on SPC5 family microcontrollers and have a couple of questions regarding its features:1) Licensing Requirement:Does SPC5Studio IDE require a licensed version for full functionality, or is there a free version available for all users?If there is a free version, are there any restrictions or limitations in its features compared to the licensed version?2) Programming the MCU Using a Debugger:How can I program the SPC5 family microcontroller using a debugger in SPC5Studio?What are the supported debuggers and programming interfaces (e.g., JTAG, SWD) for this IDE?Is there a step-by-step guide available to configure and use the debugger for programming and debugging SPC5 MCUs in SPC5Studio?3) HAL Layer Support:Does SPC5Studio provide support for the Hardware Abstraction Layer (HAL) for SPC5 family microcontrollers?I would appreciate any insights or official documentation regarding these topics.Thank you in advance f

We embed LIS3MDLTR on our board that we produce, because this has high sensitivity: 6842 LSB/gauss. This corresponds to 0.146 mgauss/LSB, if I convert correctly. The other products has significanltly lower sensitivity: 1.5 mgauss/LSB. What are you proposing to replace the LIS3MDLTR once it is discontinued?https://www.mouser.com/PCN/STMicroelectronics_15054_1.pdfRegards
