Where can I find the st-nucleo-lora-gw-atfw-v2.0.2.bin for the NUCLEO-F746ZG board 

I've been reading about GPIO and what can be triggered. I see an event can be triggered. Events can be connected to peripherals to have some control without the CPU intervening. I can't find good documentation showing how to connect or effect peripherals. I'm hoping there is a way to trigger a DMA channel to transfer data with a GPIO without a timer in between.Are GPIO events the way to trigger a DMA transfer with an external signal? Interrupts are too slow. Timers can do it but are they necessary?

I have an MT25QL01GBBB8ESF-0SIT controlled by an STM32F765VGT6 microcontroller. This was coded using C and the STM32 HAL in the STM32CubeIDE. It was verified working using different SPI commands such as read JEDEC ID, page program, etc. However, after writing to the nonvolatile configuration register, all the tested code stopped working.  Now, I am trying to fix this issue using the power loss recovery function and interface rescue functions of the flash memory. But the flash memory still does not work properly. Would appreciate help in fixing this issue. Let me know if any more information is needed. I have tried resetting the chip using software and hardware reset pin. I also have an exact duplicate of the chip connected to the same SPI line and verified all the code to be working properly except for the write nonvolatile configuration register function as I did not want to corrupt that chip as well. Currently, I am trying to implement a power loss recovery and in

Hello,Can we copy ST demo software(middleware) if we use ST25R3916 chip but not not using ST MCU?Lets say I am using PIC microcontroller to talk to ST25R3916. Can I copy Auto Antenna Tuning algorithm provided in st24r3916_aat.c/.h?Thanks! BR,Cindy 

I am trying to understand what I am doing wrong here. The following image was captured during a debug session to show strange behaviour.In the If statement ap->enable and ap->active are both true, but ap->relay_map is 0, as shown on the right, so this should evaluate to false. So why does the processor execute the statement within the brackets (shown by the green highlight) since the If fails? It actually crashes the processor because the index evaluates to -1 which is out of bounds of the relays array.

Not sure why it is mapping in the upper range of DDR.I have been using the logic analyzer example.

I need to build an MQTT demo from scratch using STM32CubeIDE where the STM32 board will act as the publisher and Adafruit IO will act as the subscriber. I want to implement this without using FreeRTOS and LwIP, focusing only on publishing the message. I need a step-by-step guide on how to accomplish this.

Hello, Im using STM32H745 on custom board, with Micron Flash Memory (MT25QU512ABB)Board is tested, I was able to manage NOR memory through QSPI.I tried to change nonvolatile configuration register to set two things:Number of address bytes during command entry to 4-byte address modeEnable Quad I/O protocol This is code I used:uint8_t QSPI_Set_Nonvolatile_Reg_Config(void) {   QSPI_CommandTypeDef sCommand; uint8_t test_buffer[4] = { 0 };   /*read configuration register*/ sCommand.InstructionMode = QSPI_INSTRUCTION_1_LINE; sCommand.Instruction = 0xB5; //READ NONVOLATILE CONFIGURATION REGISTER sCommand.AddressMode = QSPI_ADDRESS_NONE; sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE; sCommand.DataMode = QSPI_DATA_1_LINE; sCommand.DummyCycles = 0; sCommand.DdrMode = QSPI_DDR_MODE_DISABLE; sCommand.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY; sCommand.SIOOMode = QSPI_SIOO_INST_EVERY_CMD; sCommand.NbData = 2;   if (HAL_QSPI_Command(&hqspi, &sCommand,

I am really confused about driving mosfet. read many documents regarding this. some documents says gate current may be 2.5A, some says it may be 50mA.what is the actual formula to calculate gate current?I am using IRF510 (H bridge conf.) at 24V, 700 KHz.

Hello,   Am working on STM32L412RBT6. We made a custom PCB for our product and Am trying to PD2 as digital output as toggle function. I can't able to find any high output at PD2. The pin PD2 is always remains low. Please help me on this   

Hi Guys, New in STM32 design. We are going to use STM32G4 MCU (specific P/N hasn't been selected yet).We want to use dual image boot (for upgrade option). I need to choose an external QSPI flash for that.What is the maximum image size for STM32G4? Thanks Shay

Hi I have 4 sensors in configuration all have separate address and initialize ok. when first sensor start ranging I check the state vl53l8cx_get_power_mode wake it up and it ganges with no errors. but then I want to put it to sleep, so I again check the state  vl53l8cx_get_power_mode and sensor gives me 0x05 value instead of 0x04 expecting for wakeup state. Any reason for that behaviour or what does state 0x05 mean?

Dear Team,    I need your help for configuring BLE on B-L4S5I-IOT01A board. I got some example BLE in B-L475I-IOT01A.But it is different from that board could you please help me to configure and use Bluetooth via .ioc file.

Hi，allI noticed that the ethernet driver stm32mp13xx_hal_eth.c in the STM32CubeMP13_V1.1.0 already supports PTP, When will STM32CubeMP2 package be available, and since the STM32MP2 series supports TSN, whether EST(IEEE 802.1Qbv) and FPE(IEEE802.1Qbu) functions are supported in the driver? @MWB_CHa ,I see that PTP function is added by you, so do you know the relevant information?

Hi Gfx Team,Could you comment on this please ?I tried to View.add () heap allocated container and it seems to be working Okay.The container might be statically allocated as well. The key point is, the View is not aware of it at compile time.Before Transition to other screen, I remove the widget from the View and delete it.void ScreenView::tearDownScreen () { if ( nullptr != pWgt ) { remove ( * pWgt ); delete pWgt; // heap allocated pWgt = nullptr; } ScreenView::tearDownScreen (); }I found two (contradicting?) posts by ST team related to this approach.One says this is not possible (should be avoided) @Osman SOYKURT "if you mean that you want to create a new instance of a widget during runtime, it's not possible."https://community.st.com/t5/stm32-mcus-touchgfx-and-gui/dynamic-screens-how-to-create/m-p/593246And second one provides an example (does not say it is not possible) @GaetanGodart "I have made an example that dynamically adds elements to the scrollable conta

Dear A.Ziru,Apparently I'm having the same problem as you when trying to receive MIDI data from a USB device (in this case it's a guitar multi-effects pedalboard). How did you solve the problem? Where and how did you defined that MIDI class descriptor?In my case, the USBH lig gets stuck in this while loop:while ((ep_ix < pif->bNumEndpoints) && (ptr < cfg_desc->wTotalLength))I seems that the function inside the while loop:pdesc = USBH_GetNextDesc((uint8_t *)(void *)pdesc, &ptr);never increments the pointers to the end values.I still need to study more the descriptors and the types of intefaces to better understand what is happening.I would appreciate if you could indicate the path you followed to solve the problem.Best regards,Moreto

Hello, I have a question about the FSMC and FMC protocols in the F4 series. Well, I have a configured 4" waveshare display configured for FSMC in STM32F407G. Due to lack of space in the flash, I am forced to add memory (I want to do it using QUADSPI, which this MCU does not have). So I decided to switch to STM32F469 which has QUADSPI. The only the problem is that this processor has the FMC protocol instead of FSMC, I wanted to ask what the difference is between these protocols and whether there is any significant difference in the case of parallel display support

Greetings, I am trying to blink LED using baremetal programming. I am just starting bare metal programming. My LED on Nucleo - F070 board is not being turned ON. I checked register values on data sheet and user manual and it seems to be correct. RCC and GPIOA are in different bus and I was confused a bit. I have mentioned the code below. Kindly, help me getting through this. Thank you so much in advance.   // Where is the LED connected // Port - A // Pin - 5 #define PERIPH_BASE (0x40000000UL) // Base addr. of peripheral in memory #define OFFSET_AHB2PERIPH (0x08000000UL) // In bus AHB2 0x4800 0000 is the address of GPIO port A & this offset + base value = GPIOA PORT A in memory #define AHB2_PERIPHBASE (PERIPH_BASE+OFFSET_AHB2PERIPH) // 0x4800 0000 is starting point of AHB2 #define GPIOA_OFFSET (0x00000000UL) #define GPIOA_BASE (AHB2_PERIPHBASE+GPIOA_OFFSET) #define AHB1_PERIPHBASE (0x40020000UL) #define RCC_OFFSET (0x00001000UL) //0x4002 1000 is the s

Hi, Im using NUCLEO-H753ZI board and i want to send raw data to computer terminal. i tried to by using USART1. according to the schematics i can send data via USRAT1 through the USB power connection and it not working. i also tried to use USB_DEVICE to send the data but it fails again. in my last project i have used NUCLEO-U575ZI-Q and i send the data with USART1 and there were no problem at all. can someone can help?

Hello,I have developed a breakout board for the STM32WL5MOC for development purposes and it uses both rf switches and the wiring is identical to the B-WL5M-SUBG1 evaluation board.Running the B-WL5M-SUBG1 sample application SubGhz_Phy on my board and I can only receive, but the board does not send anything. This applies to both LoRa and FSK. The output of the USART debugging looks identical.My board does not contain any of the sensors of the B-WL5M-SUBG1 board. Is this likely to be an issue with my circuit board or is there anything in the software that I need to adapt? I am using the STM32WL5MOCH6TR version.Thank you,Daniel   

I'm using TIM1 to write a DMA buffer to the built-in LED. I'm trying to get the Transfer Complete callback to trigger. I've tried setting hdma->XferCpltCallback to a function. I suspect there is an interrupt enable flag I need to set and probably clear.Here's my main.c: /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2024 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************************************** */ /* USER CODE END Header */ /* Includes ------------------------------------------------------------------

I've just spent hours trying to get a DMA to trigger and interrupt when transfer is complete. I was using HAL_DMA_Start() instead of HAL_DMA_Start_IT(). I found HAL_DMA_Start_IT() by looking through the source code.Where are the HAL libraries documented?

hello all;i wondered if there are good guidelines for power consumption vs. clock, and, how low can the processor clock run? complex, i think, especiallly if one needs to run certain peripherals like ADC, or i2c... thanks!

Hello, ST expertE.g. GPIO PD4 functions as falling edge interrupt pin on STM32F407. Before the falling edge this interrupt is disabled by HAL_NVIC_DisableIRQ(EXTI4_IRQn).  What happened if HAL_NVIC_EnableIRQ(EXTI4_IRQn) is executed after the falling edge? The interrupt will be ignored or be captured immediately after HAL_NVIC_EnableIRQ? Best RegardsYang

Hello,I am working with STEVAL-SPIN3202 to develop motor control solution. I am using the Motor Control Workbench 6.2.1. I could generate the project using the workbench, however when i Connect the evaluation board, window with FAIL.txt opens which reads "The interface firmware FAILED to reset/halt the target MCU".Thus I am not able to connect to the board. I have tried connecting to the board using ST-Link Utility, however it gives the error message "Can not connect to target".I have tried some of the solution mentioned on the forum but the issue still persist.Please guide me so that i can get my motor running.
