I am working with the above device. I have created an .IOC file and auto-generated code. I can see the GPIO configuration for the simple I/O, but I do not see any pin configuration for the ADC inputs that I have selected. I assume that I will have to add these to the MX_ADC_Init module.I have attached the .IOC file that I have created.

Hi, I'm developing an application, which require ADC channel changes when an analog watchdog interrupt triggers. Now in my IRQ routine, I'm having issues with consistent interrupts triggering, blocking my code outside of the ISR intended to change my channels and run my application. Is there any way to stop this from happening ? I've tried __disable_irq(); with no luck. And utilizing __enable_irq(); as well. What I want to do is, prevent all the other interrupts occuring while I am in the ISR, control the flow of the code. I can't use scan mode scanning multiple channels or the DMA, this is the only way for my application to work. Thanks,   

Hi,I recently started exploring what STM32WL MCUs offer but I don't really understand a few things yet:1. I read somewhere that these STMs are based on SX126x LoRa radio. Is that the case?2. If so, does enabling "SUBGHZ_PHY" in middlewares in CubeIDE allow me to control this built-in radio with some simple HAL functions as if i was controlling a seperate LoRa module connected via SPI/something else?3. Based on questions 1 and 2, can I communicate between 2 STM32WLs with LoRa as if I was using simple separate modules?4. Can these STMs communicate with normal SX126x based modules? If so, with what chips exactly?5. What are the differences between STM32WL55 and STM32WLE5?I'm sorry if these questions have been answered before but either I didn't find them or I just wanted confirmation.Adam

Can anyone tell me a sample code for LTDC display where im using stm32h735 and using a particular image of         40 x80 and wanted to display on LTDC display. Is there any better way to learn how to code for LTDC   

Hi,my app works fine when I use the internal clock but if I switch to external clock I obtain HAL_TIMEOUT from function HAL_RCC_OscConfig().The external clock board schematic is:Clock configuration is:The main.c is:   /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2023 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 ------------------------------------------------------------------*/ #include "main.h" #include "adc.h" #in

Hi @mƎALLEm,I need to develop a unique serial number for one of our products that will go into production soon. I'd rather use the UID that is built into the STM32H7A3 chip but I have some questions.I understand that it is a 96bit value that I can read from the chip but I'd rather not have to use such a long and unwieldy number.I looked at page 2920 of the manual RM4055 but it doesn't really tell me which byte is for which variable (Lot, Wafer, Die, etc).This number will need to fit onto our 7" display as well as the serial number label on the product's back side.Has anyone else been able to figure out the UID format?Thanks,Richard

Other than reserving pins for the hardware-implemented debug interface (Fig. 1), what are the effects of the highlighted settings of the "Trace and Debug" category of CubeMX (Fig. 2)? Fig 1: Debug infrastructure (RM0433) Fig 2: CubeMX Trace and Debug Changing those settings has no effect in regard of code generation. How would one utilize i.e. External Trigger Bi-directional? I would have expected the system to halt (essentially triggering a breakpoint) on a signal change of the reserved TRGIO pin when activating this setting - but nothing happens. The same is true for the other direction, triggering a breakpoint does not change the value on the TRGIO pin. The same goes for the setting Trace Synchro SW (x bits). SWDIO and SWCLK can be used to communicate with a debugger, but TraceD0 seems to do nothing? I could not find an answer in the datasheet as referenced by Table 595 in RM0433. 

Hi,I have a Nucleo-F767ZI board, and am trying to configure it to use its LEDs, USART3 which is the virtual com port of the ST-Link on the board, and eth, I added LWIP, but I am unable to enable the LWIP_SOCKET as it requres to enable LWIP_NETCONN, by looking through the "General Settings" and "Key Options" with "Show Advanced Parameters" checkbox checked, I did not get a clue on how to do it.   RegardsChao

Hi,I'm currently gaining experience with the STM32G4, whose ROM bootloader supports various interfaces. AN2606 describes the configuration of the pins occupied by the interfaces.Various pins are operated in push-pull mode, which can lead to undesirable effects in an external circuit.My question is whether it is possible to deactivate unneeded interfaces in the bootloader, e.g. via option bytes, or whether this can only be achieved with a separate bootloader.Thanks in advance for your feedback!

Hello, I have made a custom external flash loader(.stldr) file for my STM32 based board. Reading the content of the external flash via CubeProgrammer works fine. But when programming i run into the following problem: CubeProgrammer tries to write partial pages, which fails.device setup in Dev_Inf.c:struct StorageInfo const StorageInfo = {#endif"W25Q_BurnerHMI_PT1_loader_v1", // Device NameNOR_FLASH, // Device Type0x70000000, // Device Start AddressPAGE_COUNT*MEM_PAGE_SIZE_BYTES, // Device Size in Bytes (8192 pages * 512 bytes)MEM_PAGE_SIZE_BYTES, // Programming Page Size (512 bytes)0xFF, // Initial Content of Erased Memory// Specify Size and Address of Sectors (view example below){{SECTOR_COUNT, MEM_SECTOR_SIZE_BYTES}, // Sector Num (512), Sector Size (8192 bytes){0x00000000, 0x00000000}},}; The image i'm writing has a size of 2097152 bytes (2MiB) and in the UART debug print i can see that CubeProgrammer is splitting the image like this:Write(Address:0x70000000, Size:0x7D500, buff

Hi,I need to service an external watchdog when a flash sector is being erased. The sector being erased is in the same flash bank where code is executed from. Before I try to jump and run from RAM I had a few questions.Where is flash stall discussed in the reference manual?Given the chip architecture, is there any issue with toggling a pin on Port G when a sector erase is ongoing? In other words, is the AXI bus matrix stalled during a flash erase?Thanks! 

Hello,i have problem with custom board assembled with STM32F767BIT6. I'm trying to interfacing LCD-TFT DEM 800480K3 TMH-PW-N which is assembled by HX8264E, HX8664B drivers. I'm using RGB888 interface configured via STMCubeIDE filled by resolution 800x480 with 1 layer and small buffer 320x240 located in internal SRAM on address 0x2003FFFF(i have 8MB external SDRAM but i'm trying to use small buffer in SRAM for workaround first), inverted DE polarity, clock for LTDC is 32MHz. But LCD still doesn't work. So i connected oscilloscope and i see correct 32MHz pixel clock, i see correct HSYNC but VSYNC is always low and DE sometimes sent some chaotic pulses or rest arround 1,7V. I checked connection on HW and it looks fine.(When i try full resolution 800x480 for layer i've got transfer data error and fifo underrun error. When i tried external SDRAM which is probably badly configured im not unable to reflash STM because STLink is not able to find my STM32, then i have to full erase chip via STM

Hi,I have seen that the new STM32WL33 have support for 4-FSK, high receive sensitivity and wake-up receiver LPAWUR, which is beneficial for both high-data-rate and long-range applications. However, LoRa support is reserved for STM32WL55 and STM32WLE5, which don't support 4-FSK.Will there be a controller that combines both LoRa and also 4-FSK support, and perhaps also higher sensitivity and LPAWUR?Thank you very much!

Hello Support Team.Good Day.We have chosen the STM32G484VET controller for our product.According to the firmware architecture, we intend to create two separate partitions, one for safety-critical (non-upgradable area) and the other for non-safety-critical (Upgradable area)When we will go to certification that time we will only certify the safety-critical code.So can you provide me guidance for code separation for safety and non-safety code?If you have any examples of the same STM32G4 series, please share them with us.Thank you, Hiren R. Thumar.

Hi,I want to set the raw data to around 2k bandwidth and receive all data through FIFO.From what I understand, to set it to 2k bandwidth-Bandwidth ODR/4 = 2.6kHz, HPCF_XL = 0, LPF2_XL_EN =1-FIFO_CTRL3 BDR_XL = 0b1010 ( 26667Hz ) And at this time, if the speed of BDR_XL value is greater than the set bandwidth,  all sampling data can be received from FIFO buffer.is my explanation correct? Additionally, what are the units of the BDR_XL value? is 2666.7hz unit?

Can I ask you about the VL53L8 series.Can the VL53L8 series use multiple at the same level at the same time, the number is greater than 4, will the middle affect each other, I may need to go through several 8*8 to form a larger depth map? Is the distance measurement in the TOF depth map obtained by this sensor in the middle of each small matrix?

Hello .According to the reference manual, the default RDP level is set to level 1. However, after performing a full erase with ST-Link and then writing the hex file, the RDP level was found to be set to 0.I would like to set the RDP level to 1 at the stage of writing the hex file with ST-Link without using software to control the registers. Could you please tell me how to do this?Best regards,  aki

Hi,I have created two tasks. Task A and Task B. Task A has higher priority. Task receives data through UART and enques this data into queue. Then, Task A is blocked for 1 second. Task B comes into picture and dequeues the data from queue. I send 8 bytes of data, I can see that Task A writes to buff array when I send message through via serial terminal on UART.I send buff array to the queue, then I enqueue the data from queue and write it into buff2 array. When I read the buff2 array I only see the first byte of buff array. Please see below serial terminal output.    /* 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 f

Dear community members,Because I am using the stm32 Nucleo board with st32cubemx and stm32cubeprogrammer, how can I get the library and set all the parameters of the AEK-COM-ISOSPI1 so that it can communicate with the AEK-POW-BMS63EN. Any help would be very much appreciated. Thanks,TH.
