After updating to STM32CubeIDE 1.2.1 I cannot open anymore .ioc file in STM32CubeMX device configuration tool. When I double click on existing .ioc in the project text editor opens instead of STM32CubeMX.

Hi,I suddenly get this kind of interrupt in a code that was previously working perfectly. The instruction that makes this interrupt arise is *dst=*ptr. You can check below the function:void readHistoryFile(unsigned short * dst){ unsigned short * ptr = HF_P_ADDR; //Pointer to Flash position (starts at 0x0807F800) for(int i=0; i<N_HF_EL;i++){ *dst = *ptr; ptr++; //Increment Flash pointer by 2 bytes dst++; //Increment destination pointer } }The initial dst address is 0x2001ff30.I can copy some Bytes but, whenever I try to write into the address 0x2001ff50, I get the said interrupt. Also, have in mind that this problem showed up suddenly, without any change to the firmware.Is there any good way to debug this mysterious behavior?Thanks in advance

Hello,Is it possible to use uart with dma, so that on idle we also get informed, so that we can read the rx data ?I found no example in hal cube for using UART with DMA in such "real life" scenario, only in simple full buffer fill - which is not practical.I use stm32h7.Thanks,ranran

Developing with B-L072Z-LRWAN1 LoRa®Discovery kit with sensor board and GNSS Teseo.I added an OLED ssd1306 and connected it on IC2 PB8 PB9. I can send commands but when I send data I very often get a display hang. How should I handle PB8 PB9? Should this be terminated? Is it a jumper to set on any of the 3 boards?

I want to use a SIP with ST32MP153 and it uses PC13 to PMIC wakeup, PC1 is used for MDC so I'm left with only PI8 so can't use active tamper.I sit possible to use Ethernet without MDC so I can use PC1 for active tamper with PI8?

Hi,I've developed a UI with touchGFX where I'm using a swipe container and to finish my application I think I need a way to know the page I was in the Swipe container. The steps I do are.:1) in page x of the swipe container i press a button to go to another screen2) when I'm in the other screen I press a button on a keyboard to come back to the previous screen and I need to come back exactly to the page of the Swipe container I was before.I've read some discussion on the community about that but If I've understood well, the only way is to add manually a custom container. But I'm at the end of the UI so I would prefer to not follow this way. Is this the only way? So far I've tried to add this function to SwipeContainer.cpp but I got errrors:uint8_t SwipeContainer::getSelectedPage(){  return currentPage;}and to SwipeContainer.hpp (in the public part)uint8_t getSelectedPage();In the screen where the swipe container is used: uint8_t Screen01View::SaveCurrentPage(){ currentPage=Sw

Hey all! I'm working on a project with the STM32L151C8T6. However, my STM32CubeMX generated project (For STM32CubeIDE) launches straight into a hardfault. Any idea what could cause this or what I could debug to get this to work? I've already generated a new empty MX project that doesn't have anything configured - same problem. Thanks!

Hello,I'm using ST25R95 in my project. I'm sending pulse signal in order to transit from powerUP mode, and after it the Idle command in order to enter hibernate mode.Idle command: {0x07, 0x0E, 0x08, 0x04, 0x00, 0x04, 0x00, 0x18, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00};I'm using custom PCB and current consumption after I send Idle command drops from 1.69mA to 1.14mA. The rest of circuit on the PCB consumes 0.14mA, which means there is about 1mA current somewhere in the NFC circuit. In the DB2382 Rev 5 document, I have found reference design for the ST25R95, and SSI_0 is connected over 3.3kOhms to VCC, and SSI_1 over 3.3kOhms to GND. That is the only difference from mine design, because I have connected those 2 pins directly to VCC and GND respectively (SSI_0 to VCC, and SSI_1 to GND). Could this be an issue and is that reason for this 1mA power consumption, or do I need to do something else besides sending the Idle command?Best regards and thank you in advance,Dragan

Hi，STM32H743 Cortex M7 core with double precision FPU, it process 32bit float data(single precision) in my project, I wonder if it affects efficiency and performance of FPU, In my performance testing program, it's no different from Cortex M4 FUP.Thanks!

I'm using the STM32F072RB MCU and I am trying to increase the SPI baud rate. The HSI48 Clock is 48MHz and the minimum SPI clock prescaler is 2 which comes out to be 24Mbit/s. However, it gives me an error stating that the baud rate is more than 18MBit/s. Why is this and is there anyway to change it?

A STM32F746 on a custom board powered by the step-down regulator TPS62082 by TI doesn't start in about 90% of cases.I flashed (which always works fine) a simple test program, which flashes two LEDs alternately:int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init();   while (1) { LED1; // LED1 on, GPIOx->BSRR = ...; LED20; // LED2 off, GPIOx->BSRR = ...; HAL_Delay(1000); LED10; // LED1 off LED2; // LED2 on HAL_Delay(1000); } }The STM32 runs at 200 MHz, using HSI and LSI. In about 10% of cases after power on, the LEDs light up. The other 90%, both LEDs remain dark. If the LEDs remain dark, a manual reset by pulling NRST low always starts the STM32.The first idea was that there is a power issue, but I set the Brown Out Reset level in the option bytes to around 3V. Looking at Vin (3) and Vout (1) of the regulator, voltage seems to be fine. (2) is the output of a GPIO output which was initialized to HIGH in MX_GPIO_Init() -- but it remains LOW, which means t

Hi ST communityI want to do register level coding and make device drivers and do peripheral coding for STM32 MCU ( i have STM32F103 and STM32wb55) using STM32cubeIDE.Now the thing is I am not able to figure out how to create a project in STM32cubeIDE which has only peripheral register header files(STMf103.c and stmf103.h) for making device drivers from scratch.​Don't want to use STM32cube Mx as it automatically generates all Low-level codes ​On the net, most of the resources for doing register level coding is done by using Kiel and STM32 Cube MX.But I don't want to use Keil and neither CubeMX for generating my codes.​

Hello,I would like to send the value of a parameter from screen1View.cpp to Model.cpp. Is there any way to do this?I work with TouchGFX 4.14 and STM32429-EvalThanks!

I'm picking up a project I started last year. I'm developing on the STM32F746-DISCO board. It was not a smooth process getting it going. Various Youtube videos helped me over the issues. I am hesitant to upgrade to the latest. For fear of breaking stuff that is working. How much 'better' is the current stuff? Also, is there a video/demo of the new graphical widget? What other new widgets have been added? Thanks, Bob

Hi!I want to report a bug.I tried SDADC and I found a bug.Also it should stand "Multi mode" not "Mulimode" and the STM32CubeIDE 1.5.0 (I'm using) missing calibration options in the STM32CubeIDE project starter.

Hi,I'm trying STM32F769I-DISC1 board with an Sd Card 8 GB Class 4 (4MB/s max) performance, the SD Card is FAT32 with 4096 bytes blocks to fullfill STM32CubeIDE allocation unit values. I build the testing project with the onboard SDMMC2 with RX and TX on DMA as 4 bit wide. I'm using FATFS to write data with f_write() function. With this setup I achieved 800 kB/s but I need 192000 freq * 3 bytes * 2 channel = 1152 kB/s or more. A thing that I don't understand is why if I change PLLSDMC frequency, SD Card will have same performance with 48MHz clock (/8) or 25 MHz clock(/15)... Do you know some tips to increase performance? Thank you very much, the product is great actually permit to record 96kHz * 24 bit * 2 channel audio streams.

How to remember data after power off in STM32F746G DISCO?Andrzej

Posted on February 03, 2017 at 14:40I have Nucleo-F767ZI board and want to use Arduino protoshield to ease making connections to a peripheral (I will solder 2x8 pin header to the shield and use a ribbon cable). However I cannot find any PDF on ST Zio connector, which will apparently be used by the Arduino shield. Where is the data?Also, I'll be using DCMI and I'm worried that ST Zio will pin-collide with it. So it's about: which pins are used by ST Zio, particularly with Arduino shield?Best regards,Sebastian#arduino #dcmi #pins #zio
