Does STM32 support dual-ADC multi-channel sampling? For example, ADC1 enables IN1 and IN2, and ADC2 enables IN3 and IN4. Is the storage method in the adc_buffer as follows? adc_buffer[0]: High 16 bits = ADC1 IN1, Low 16 bits = ADC2 IN3 adc_buffer[1]: High 16 bits = ADC1 IN2, Low 16 bits = ADC2 IN4 And how should I configure this in CubeMX?

Can you share the routine for configuring USART2 interrupt transmission and reception on stm32N657? It took a long time to configure, but it can only send, but the receive interrupt cannot be triggered!

I'm using a digital clock in my application but I'm seeing a strange behavior between what I've set into TouchGFX Designer and the simulatorThere's no custom code in the applicationWhy is that? What should I look for?

Hello,I am working on a point-to-point communication project using the P-Nucleo LRWAN2 board package. In this setup:The NUCLEO-L073RZ acts as the transmitter.The NUCLEO-F746ZGT6 acts as the receiver.I have downloaded the LoRaWAN package for STM32Cube provided by ST, but I am facing difficulties using the library in STM32CubeIDE.Here’s what I’ve done so far:I created a new project in STM32CubeIDE.I started copying the .c and .h files from the LoRaWAN package into my project.I included the necessary header files, but I am still getting "undefined reference" errors during the build process.Could someone guide me on the correct way to integrate the LoRaWAN library with STM32CubeIDE? I’m not sure if I’m missing any specific configurations or additional steps to properly set up the project for point-to-point communication.Thanks for your help!Inc and Src Folder Console main.c file https://www.st.com/en/evaluation-tools/p-nucleo-lrwan2.html https://www.st.com/en/embedded-s

i want clapping and outside sound provide to the SPH0641LU4H microphone and that is i connected to stm32 nucleo-L476RG board and in my pc's putty. i can tried heat and trials methods in that using DFSDM1 to configure the microphone and USART2 for conveyed to the PC, but it's got wrong and i just confused to how to do that. Let me explain details about mainly what configuration i was doing, in DFSDM1, i was configure channel1 parameters with SPI with rising edge and spi clock is internal SPI clock, offset is 0, right bit shift is 0*00, in analog watchdog parameter i was using filter order is sinc 3 filter type and oversampling is 32. now in filter0, regular channel selection is chennel1, continuous mode, software trigger, with fast mode and dma mode enabled, now in injected channel section all i was used to disable, now in filter parameter sinc order is 'sinc 3 filter type' and fosr is 16 and lors is 1. i configure gpio pins of PB12 is the data_IN and PC2 is the clock_out, i was not ena

Hello Developers,I am currently facing an issue with joining the LoRaWAN network using the LoRaWAN AT Slave example provided by STM32Cube_FW_WL_V1.3.0 on a new Nucleo STM32WL55JC1 board. Despite following the provided instructions and configuring the example for the EU868 region, I am unable to successfully join the network.Here are the steps I have taken and the observations I have made:Flashed the LoRaWAN AT Slave example to the STM32WL55JC1 Nucleo board without any apparent problems.Configured the board for the EU868 region.Entered the necessary AT commands for configuring Device EUI, Application EUI, Application Key, ADR, and Data Rate.Initiated the join procedure with AT+JOIN=1 to use Over-The-Air Activation (OTAA) mode.However, despite multiple attempts, the join procedure fails consistently, and I receive a "JOIN FAILED" response from the LoRaWAN module.I have tried adjusting parameters such as Data Rate (AT+DR) and Transmit Power (AT+TXP), but the issue persists.Here is a snipp

I am developing an application from LoRaWAN End Node example in STM32WLE MCU. I would like to use serial communication through already configures USART2 to configure some tests from a python script, but I cannot find the interrupt function that is called when a message is received by my the MCU.There is a lot code and macros. Maybe I am forgetting something.Could anyone help me please?   Thanks in advance.

Hello,I'm looking for a board that provides all program/debug signal on a header while allowing to disconnect on-board MCU.I've looked at a few NUCLEO boards - only JTCK, JTMS, NRST, SWO are exposed to a header (with possibility to disconnect on-board MCU using jumpers and solder bridges), but not MCO, STLK_TX and STLK_RX.Does exist a board that exposes whole this stuff ?Thanks.Pavel.

I am trying to write a ethernet loopback test and I am unable to set the destination MAC address (FF:FF:FF:FF:FF:FF) to broadcast to. Since this is for testing, we want to avoid using NetX.Is there an example of HAL_ETH_Transmit and HAL_ETH_ReadData back to back and/or a function in the API that can set the destination MAC address?

We are currently using the STM32G0B0VET6 microcontroller (100-pin LQFP package) in our design for interfacing a 480x320 ILI9488 TFT display via the SPI interface. Our hardware is already finalized and PCBs have been fabricated accordingly.During our development and testing phase, we encountered significant performance limitations when attempting to render full frames to the display over SPI. Despite optimizations, the SPI interface on this MCU does not meet our display refresh requirements for smooth and responsive graphics.Is there any pin to pin alternate MCU that can replace the current mcu for better display performance through SPI without changing the pcb design.Thank you.

Hi,I have a well functioning application transmitting on uart4 using GPDMA1 CH1.If I turn on DCache, then it does transmit the correct length, only all characters are 0x00 (no problem in turning ICache on).In HAL_UART_Transmit_DMA(huart, (const uint8_t*)pTx, len), if I make this substitution: HAL_UART_Transmit_DMA(huart, (const uint8_t*)"Hi "/*pTx*/, 3/*len*/), then it works.I have tried allocating the variable pointed to by pTx to just about any available memory area / type without success.Any suggestions? 

Dear Friends, I’m developing firmware for the STM32WB05KZV6TR with these sensors: LIS2MDLTR (magnetometer), LSM6DSO32XTR (accelerometer/gyroscope), and HSFPAR004A (force sensor).  My PCB is already printed, and components are installed, so I can’t add a host MCU.  I need to implement BLE export (to a mobile device), Flash writing, and sensor data export using only the STM32WB05KZV6TR. Details:MCU: STM32WB05KZV6TR (192 KB Flash, 24 KB RAM).Features: BLE GATT server, sensor data handling, Flash storage.Approach: Bare metal programming (FreeRTOS/Zephyr may be too heavy).Questions:Can I fit this functionality within 24 KB of RAM and 192 KB of Flash? Any optimisation tips?Are there examples or libraries for these sensors with the STM32WB series?How should I structure the firmware to balance sensor reads and BLE notifications?Is STM32CubeMX the best tool for configuring peripherals and BLE?I’d appreciate any advice, code snippets, or example projects!

I am currently working with the STM32WB55RG microcontroller on the NUCLEO-WB55RG development board and am encountering an issue while attempting to install or update the BLE wireless stack using STM32CubeProgrammer.Upon attempting to start the wireless stack or upgrade FUS, I receive the following error: Error: FUS_STATE_IMG_NOT_FOUND: Firmware/FUS upgrade requested but no image found.(such as image header corrupted or flash memory corrupted)Error: Start Wireless Stack Operation Failure! Please, try again   I would appreciate guidance on:Confirming if anti-rollback is active on this deviceWhether a forced FUS or stack reinstallation is possibleAny tools or procedures to resolve this statePlease let me know if any additional logs or files are needed for diagnosis.

Hello,I try to use I2S in full duplex mode master with DMA but it doesn't work as expected.The I2S is configured in 24 bits @32Khz.DMA TX and RX are configured in half-word circular mode.I can send data manually but if I loop the input to the output using software, nothing comes out even though there is data on PB4.DMAs are started with :HAL_I2S_Transmit_DMA(&hi2s3, I2S_DAC_Buffer, 2);HAL_I2S_Receive_DMA( &hi2s3, I2S_ADC_Buffer, 2);I used the function HAL_I2S_TxCpltCallback(I2S_HandleTypeDef *hi2s) in main.c like this :void HAL_I2S_TxCpltCallback(I2S_HandleTypeDef *hi2s){I2S_DAC_Buffer[0] = I2S_ADC_Buffer[0];I2S_DAC_Buffer[1] = I2S_ADC_Buffer[1];I2S_DAC_Buffer[2] = I2S_ADC_Buffer[2];I2S_DAC_Buffer[3] = I2S_ADC_Buffer[3];}I checked by flashing an LED, the callback function is called as it should.Why doesn't it work?I can provide other parts of the code if needed.

Hello, I'm encountering the same issue, and i started debugging the embedded bootloader protocol manually. Or i'm starting getting crazy, but what specified in AN3155 is not respecting what i'm having on the serial port.I'm using NUCLEO-WB09KE(MB2032B) mounted on MB1801D.When moving JP1[MB2032B] to BOOT mode, SWD is not available.I'm only be able to get on bootloader mode (not with CubeProg) but as below.Problem 1 - GetVersionComand (documentation mismatch)I sucessfully entered in BL (Ack = 0x79), however GetVersion command is totally ignored. I then tested with another command to see if the communication with embedded BL works.Something worked but not as expected. Command 0x02+0xFD should reply with ACK(0x79) + N=NumberOfByte + PID. I did not see 0x79 as ACK nor the number of bytes i should get: i just got 0xD0 and 0x94.I can't find what is the DEV_ID of STM32WB09KEx, so i can't verify if what'i'm having is really the DEV_ID or something else. Anyway the ACK is sti

Hi allI am trying to make project on LWIP & FreeRTOS on STM32f407vgtx board issue what I am facing is when code is getting stuck and no task is hitting .I am sharing my project can you please check once .note: in task I am have called Lwip_Init in my First task is getting hit but when I added TCP_Client or TCPserverinit it is getting stuck.Kindly checked attached project and guide meB.RAshish

I chose the Nx_SNTP_Client example through MX and created a STM32CubeIDE project. The board I'm using is STM32H747I-DISCO.When I run it on the board, I only get the message "The network cable is connected." and I can't get a DHCP IP. When I try to debug, Tx doesn't run even once.Please help. 

I connect the PB9-BOOT0 to VDD, then power up the board, but it just run from flash(application program), not the bootloader, what's the matter? I am not firmilar with ISP, I suppose it should enter bootloader, and wait for ISP program to communicate.I want to confirm, besides connect PB9-BOOT0 to VDD, is there any other thing need be done? 

Hello everyone, I have a lot (too much) question regarding code optimisation, the safety of a code and some return value of the HAL.Firstly, I am currently using HAL and CMSIS RTOS v2.  I am using a spi bus protected with a mutexe. Assuming that I am correctly using the mutexe, is it possible for HAL_Transmit_IT or HAL_Receive_IT to actually return HAL_Busy?What I want to know is:1) Am I making too much verification? Afterall a if/else bloc is require some ressources from the core, even if it's very little.2) I read on various post that using assert was a good practice in embbeded system but I'm still strugling to know when to use it and when not. I also read that it was recommanded to always check a return value of a function when it has one. Am I using correctly the assert() function? Is there too much usage of it? Not enough? Where is it really required and when is it not?Here is a sample of a basic function for a driver I am currently working on. I'm following the same co

Hi,I am injecting a UART DMA error by using DTCM memory and DMA2. For example:// Induce a DMA error by using DTCM RAM for DMA2 which is inaccessibleif ( HAL_UART_Transmit_DMA( huart, transmit_buffer_dtcm_memory, num_bytes_to_transmit ) != HAL_OK ){// Log error}What happens is the frame error, parity error, and noise error interrupts are disabled after the DMA error on transmit. This I can see by the EIE bit in CR3.  HAL function UART_EndRxTransfer is called and clears EIE.I have a streams connected to the TX and RX lines:TX is connected to DMA2 Stream 5 - High priortyRX is connected to DMA2 Stream 4 - High priority When I try to restart the UART receiving:if ( HAL_UART_Receive_DMA( uart_handle, receive_buffer, RX_BUF_SIZE ) != HAL_OK ){// Log error}There is a check in sub function HAL_DMA_Start_IT that returns an error because the DMA stream is busy. So what is the correct way to recover/restart after a DMA and set the interrupt flags for frame, noise, and parity?\Thanks
