Solved

Hi, I am trying to use an STM32G031J6-DISCO board to get a grasp on the 8-pin STM32G031J6 MCU that I consider for building small IoT sensors (for teaching purposes). I am new to STM32 products (or ST MCUs in general). I managed to write a few variations of programs (with STM32CubeIDE v1.10.1 on Fedora 35) for blinking the built-in onboard user LED and playing with the built-in push-button as well. However, after rebooting my computer, the user LED is not blinking anymore and I now face an error message when I try to upload my code (using STM32CubeIDE):STMicroelectronics ST-LINK GDB server. Version 7.0.0 Copyright (c) 2022, STMicroelectronics.

I was getting strange results with the deadtime prescaler of the H7 hrtim and it appears that the H7 reference manual (RM0433 rev 7) is incorrect: The DTPRSC field of register HRTIM_DTxR, is supposed to get binary values from 011 to 111 (000 to 010 are reserved) which correspond to multiplication of the  tHRTIM by 1, 2, 4, 8, and 16. The provided formula is tDTG = 2^(DTPRSC - 3) * tHRTIM.But, when I set the prescaler to the HRTIM_TIMDEADTIME_PRESCALERRATIO_MUL8 define from HAL, it places a 0 in DTPRSC, while according to RM0433, it should have been 0b110 (= 6). Then when I used HRTIM_TIMDEADTIME_PRESCALERRATIO_MUL4, it wrote 1 in DTPRSC, and so on. There is not a XX_MUL16 defined. The actual deadtime is scaling in the oposite direction! The delay with MUL8 is half of the delay with MUL4, which is half of that with MUL2, ....Therefore the actual formula is tDTG = 2^(DTPRSC) * tHRTIM, so the -3 should not be in the exponent and the values of 0b000 to 0b010 are valid.

I found a slightly old project, and I would like to compile it with STM32CubeIDE.It is to add HUB function in USB Host:https://github.com/mori-br/STM32F4HUBDoes anyone know how to adapt this project to compile in STM32CubeIDE?Or how to compile the original project?

Hello everyoneI have a little problem with stm32cubdeide, when im trying to work in debug mode with the mcu stm32f469nih6 i can't modiffy or add any bit to enable the register RCC->AHB1NER->GPIODEN.I just want to set clock to activate other peripheriphal and blink any ledshows a little blue circle where should be modify and put 1 to activate, but i cant add etiher 1 or other number, i dont know what is the solution, any can help me? please Regards

I am using two PDM microphones(mems transducer) with STM32 to measure the intensity and if the intensity of the left microphone is higher than the right one then an LED should turn on and vice versa.We measure the intensity of analog signals like when the signal is higher than a certain threshold then do something(if(ADC_Val >= 3000)do something...), so is it possible to do such things with digital microphones?Is it possible to measure the intensity of sound level from PCM samples?

hello everyoneI am a new researcher in the field and I need to develop a project with arm libraries to have some fft résultas I can find the library but i dont know how to make the project run, is there anyone who can help me?

Heyin a project of us we are using the legacy STMFlashLoader to flash firmware on a STM32F103 via the system bootloader on UART1, but wanted to migrate to STM32CubeProgrammer now. In this application the PC (Win10) which runs STMFlashLoader/STM32CubeProgrammer is not directly connected (via a USB-TTL adapter) to the UART1 of the STM32, but goes through a "tunnel". This works perfectly fine with the legacy STMFlashLoader but does not with STM32CubeProgrammer.The log generated by STM32CubeProgrammer clearly shows that things break when the first chunk of data to be written is being sent.The issue is that STM32CubeProgrammer sends a chunk of 256 bytes (0x31CE0800000008FF...), while STMFlashLoader sends only chunks of 128 bytes size (0x31CE08000000087F...), which perfectly explains the issue as the "tunnel" involves a buffer of size 128.Hence the question: Is it somehow possible to set the chunk size which STM32CubeProgrammer is using for UART uploads?If not, would it possible that such a

hey,I Have a big Project on stm32 F030R8, and i would like to export/duplicateto a new board I have(G070RB).I am using Stm32CubeIDE, is there any magic option that it can do it by its self?Or I have to copy and past by hand (please no!).thanks in advance

Hi,​I setup a project for STM32F429 MCU by using STM32CubeMX with LTDC, DMA2D, FreeRTOS and TouchGFX enabled. It works very well with a splash screen and a main screen. However, when I added another simple screen, the UI freezes after some screen switch operations. The problem can be reproduced 100%, and always at the some place.​After some investigation, I found the UI task is hung in OSWrappers:waitForVSync() -> xQueueReceive() -> prvUnlockQueue() -> xTaskRemoveFromEventList()->configASSERT(pxUnblockedTCB).The reason is: memory of vsync_q (in OSWrappers.cpp) is overwritten by unknown reason. vsync_q.xTasksWaitingToSend.uxNumberOfItems is no longer 0, which cause the assert fail.I added a memory write access breakpoint, and tried to catch the 'evil' code, but it breaks in the interrupt handler: DMA2D_IRQHandler(), and the memory has been changed already. So, I lost clue here, and it seems DMA2D did some incorrect operation towards the memory.Can anyone give me some suggest

Hello.I have stm32h743vit6. After Cubemx 6.3.0, the adc clock prescaler setting is not available, it does not appear. Also, even if I open the adc channels, the adc mux is never active on the Clock Config page.In older projects (6.3.0 and earlier) adc clock settings can be configured. Is this an error?

I am coding an STM32G031F8P6. I want to set some interrupt priority values. I am looking at the programming manual, PM0223. In section 4.2 (page 82) Table 25 says that the priority registers NVIC_IPR0-7 are 0xE000E400-0xE000E4EF. That doesn't make sense, as it implies a block 240 bytes long. This block should be 32 bytes long. There is no updated version of this document, nor is there an errata listing for this. Are the priority registers the first 8 words (32 bytes) in this block, or evenly distributed in the 240 byte block?

Posted on April 19, 2017 at 09:29 Hi all Recently, I created a Win32 application to convert a bitmap (.bmp) file into a header file (.h) in order to display it in mySTM32F746G-DISCO discovery board. Everything works fine but the bitmap (24 bit depth) displays differently (see attached photo) compared to the original bitmap. Does everyone experience the same? The displayed bitmap seems to be skewed and de-colored. I have done again with a 16-bit-depth bitmap but no further advance. (I reused the BSP example in STM32CubeF7Packets for the test) Note: this post was migrated and contained many threaded conversations, some content may be missing.

Is it possible to use S2-LP to replace TI's CC1101? Below are the RF set ups in my products: //2-GFSK//data rate =175kBaud//channel spacing =200kHz//carrier frequency = 868.3mHz  //deviation =50khz//receiver channel filter band width =464kHz

Hi,I would like to create a new CubeIDE project with a IOC file (from scratch) for B-L475E-IOT01A2 that enables WiFi. I know that there are working examples (for example WiFi_HTTP_Server that works fine) but these projects do not have IOC files. I have tried to create such a new project adding es_wifi source files but id doesn't work. Probably the SPI bus should be set up in the right way together with clock configurations. Do you have any suggestions or point me to any working CubeIDE projects with IOC files?BestPST

I have a custom board with TFT connected by FSMC 16bit to the STM32F103VET6. When a new project created in CubeMX 6.7 and I try to add new software component (TougchGFX v4.21) - it told me the STM32F103VET6 does not supported. Is there a way to avoid this limitation?

HiI am using STM32F103C8T6 Microcontroller and tring to configure ADC injected channel with Timer 2 PWM in Register level. but i don't know how to enable the ADC injected channel. help meThanks in advance!

I am using STM32F031 family microcontroller and want to configure the ADC.My application requires current sensing and voltage sensing. For critical measurement like current during PWM ON time, I am using the ADC in external trigger mode, triggered by the PWM timer channel.However, for voltage sensing, I do not want the ADC to be externally triggered during the PWM ON time, instead, want to use it in regular conversion mode.How can I achieve this, since I cannot see an option to combine both triggered and regular conversion modes of ADC? Any inputs will be helpful.Regards,GD

I'm developing my first STM ethernet application and want to use it's built in MAC, from my understanding any 10/100 ETH PHY with MII or RMII should work but there's such a big list of those on market, ST Disco boards I found use LAN8740, which is expensive and somewhat hard to obtain, some tutorials I saw used LAN8720, KSZ8xxx. My main concern is if there is a big difference I'm missing out or will any of these products work same? Any experienced dev input would be appreciated on which of these IC-s is more recommended over the others.#Edit: I was planning on using F107 for it but now memory has become a concern, if anyone has a general idea of how much memory ethernet libraries usually take up, I'd love to know it.
