I'd like to only update variables, which are shown on the current screen. How do I get the current screen in a switch case structure, in the model::tick() function. I tried to alter the tick function to get the currentScreen parameter from the FrontendApplication.hpp as a variable, but this did not work

Hello,I'm trying to get LwIP working on a STM32F769I-DISC1 board but with the SBSFU bootloader.I started out with a basic project, generated with CubeMx, that sends UDP packets every 500ms (no operating system, just LwIP Raw API). This works, the board gets an IP address and I receive the data.I then changed the linker script and project settings to work with the X-Cube-SBSFU bootloader which builds and starts up but will not get an IP address. It just keeps waiting for an address.The changes I made to run with the bootloader are as follows:Changed STM32F769NIHx_FLASH.ld as attached (STM32F769NIHx_FLASH_bootloaded.ld)added includes to gcc settings in AC6 Systems WorkbenchMiddlewares/ST/STM32_Secure_Engine/Core2_Images_lwip/2_Images_SECoreBin/Inc2_Images_lwip/2_Images_SBSFU/SBSFU/App2_Images_lwip/Linker_Common/SW4STM32changed linker to gcc -z max-page-size=8add to linker libraries (-l) :se_interface_app.oadd to Library search path (-L) the path where se_interface_app.o can be foundadd t

Hi,I am working with the X-NUCLEO-NFC05A1 for testing and prototyping purpose. My goal is to detect and read RFID cards on two different card slots.I am able to read the RFID cards using the differential antenna mode with only one antenna connected at RFO1 and RFO2.However, since I want to read cards on two different location, I thought about using 2 antennas in single ended mode.I configured the IO configuration register by setting the bit Single (bit 7) and multiplexing the two antennas by toggling the bit RFO2 (bit 6) when needed as cited in point 1.2.2 Transmitter The antennas are respectively connected to RFO1 and RFO2 and both at ground using the Connector J300 on the eval board. With this configuration, I am not able to detect or read any cards. No inductive or capacitive wakeup IRQs occurs with this connection and configuration. I could not find more information in the Datasheet on how to use the single ended mode.Am I missing something important? What more should I modify?Is m

I am working with Mifare Ultralight Ev1 (Iso14443A Type 2 tag). NFC Reader is CR95HF.When I execute this command I get different answers. At first I only checked on if the answer started with 80, so they both succeed. However now I am getting in more detail on how answers work, and I see that sometimes I get a long response while at others I get 8000.Example:---------CR95HFDll_SendReceive strRequest:---------952008---------CR95HFDll_SendReceive strAnswer:---------8000---------CR95HFDll_SendReceive strRequest:---------952008---------CR95HFDll_SendReceive strAnswer:---------80085A734D80E4280000What causes this difference in response and what does it mean? -------------------------------------------------------------Also I am getting into CRC. I see that sometimes response ends with 280000, but it seems the command has been executed properly. Should I always retry unless the answer ends with 080000?

Hi,First of all I am really loving the ST25DV dynamic tags. I am currently trying to write sequential write of 200 bytes of data using I2C. I am able to write the the chip, but I was curious of how many write cycle is this considered. I am writing 200 bytes to the chip every 10mins and I want the device to last atleast 10 years. So I would like some information on the write cycles which would help me in calculating the life expectancy of the chip.ThanksAnish

For STPMIC1, when it is powered on by asserting the PONKEYn signal low, what would happen if the PONKEYn remains asserted low even after the initial POWER_ON trigger? Would it subsequently trigger a POWER_DOWN if PONKEYn long press turn off is activated? Or is the PONKEYn event triggered only when there is a HIGH to LOW edge transition (edge trigger) ?Thanks.Steven

I setted it by stm32cubemx, and just used ucpd1 as source, but it won't send source capabilities when connected the sink devices. I'm not sure it's the code or the hardware influenced it. I tested it in nucleo-stm32g071rb, and connected sink devices by ucpd1_cc1, ucpd1_cc2 and GND. And I try to use USBPD_PE_Request_DataMessage(port_num, USBPD_DATAMSG_SRC_CAPABILITIES, NULL); to send a source capabilites, but return USB_BUSY.

I 'm using Atollic TrueSTUDIO 9.3.0 with STM32CubeMX 5.2.1 and target MCU is an STM32F030F4P6.I 'm building my project but I get this error:Undefined referrence to 'ITM_SendChar'.In the second photo you can see that the folder that contains the file (core_cm3.h) that contains the 'ITM_SendChar' function is included in my project.(Properties->C++->BuildSettings->ToolSetings->C Compiler->Directories->Include Path)What have I done wrong?

I'm a relatively new user but am just about getting up to speed with STM32 family and STM32CubeIDE. I love that there is a gui that helps to generate code to configure peripherals, however I am learning to distrust some of the detals of the code generation :(One that just cost me a few hours of head scratching:I was setting up an STM32L4R5ZI (nucleo) board as a full duplex SPI slave, and had configured all the pins & settings correctly. Blocking mode HAL_SPI_TransmitReceive was working, but when I configured DMA and used the _DMA variant of the function, I could not get any of the DMA complete interrupts or callbacks to fire.I compared my code over and over again to an example, until I randomly looked at the initialization code that Cube had generated for me, which included this block: MX_GPIO_Init(); MX_LPUART1_UART_Init(); MX_USART3_UART_Init(); MX_USB_OTG_FS_PCD_Init(); MX_SPI1_Init(); MX_DMA_Init();I found that if I moved the DMA_Init line before t

I'm still using v4.10.I've read through the following tutorial and also looked at the example demo.https://touchgfx.zendesk.com/hc/en-us/articles/360018398832-Scroll-WheelNeither the item.updateText() nor the item.setIndex() functions are recognized. void Screen1View::scrollWheelUpdateItem(textContainer& item, int16_t itemIndex) { item.updateText(itemIndex); } void Screen1View::scrollWheelUpdateCenterItem(textCenterContainer& item, int16_t itemIndex) { item.updateText(itemIndex); }Can someone please shed some light.

I generated my code by stm32cubemx, and use ucpd1 as sink&dead battery, use ucpd2 as drp. But got USBPD_ERROR in USBPD_DPM_InitCore after execute " CHECK_PE_FUNCTION_CALL(USBPD_PE_Init(USBPD_PORT_0, (USBPD_SettingsTypeDef *)&DPM_Settings[USBPD_PORT_0], &DPM_Params[USBPD_PORT_0], &dpmCallbacks));"and USBPD_PE_Init success when just use ucpd1, ​why the added ucpd2 caused the ucpd1 USBPD_PE_Init error? thanks.

This is a documentation bug/request really, but I recently was trying out the HAL_SPI functions for the first time, and had set up the peripheral for 16 bit transfers.The documentation for HAL_SPI_TransmitReceive and related functions, for several of the families, across several documents and pdfs found on the internet and ST's site, all simply say that the size parameter 'Size: amount of data to be sent and received'I found a number of erroneous exmaples that use sizeof(buffer), as well as several question on this forum with incorrect information; for the record, from reading the HAL code, the size is measured in units of 16 bits (or whatever your SPI is configured for). while that makes total sense, I wish the docs made this clearer as it tripped me up - and many others. I was overrunning my buffer by a factor of 2, leading to bizarre behaviour, faults etc.took a while to unpick.For the DMA functions, I dont know yet if the size of the DMA transfer configuration (half word or word) m

Hi experts, I am designing a circuit using STM32 MCU, my application doesn't require strong MCU , so i decided to use 2 type of below MCU: STM32F103C8T6STM32F030F4P6But i want to load the hex file to chip via on board designed circuit by micro USB port. I Researched about ST-Link circuit, but it's too difficult. I don't need debug, is there any basic circuits to help me load Hex file to chip ?Thank you in advanced !Have a nice day :smiling_face_with_smiling_eyes: !

I have a simple calculate#define VREF ((uint16_t) 3300)   float X = VREF / 2000;Why X result is 1? This happen with another calculate like xx00 / xx000Thanks

Dear all,I am in difficulty to adjust Timer 3. Let me explain with examples:Internal Clock is 72 MHz and it is used for also Timer 3 as an input clock.1- When PSC: 36 and ARR: 124 it should generate an interrupt every 62,5 us (we can assume it generates exactly every 62,5us because there is tolerance due to crystal oscillator and interrupt latency. One of GPIO toggles when interrupt services and the duration is measured by a scope. Duration is measured about 64 us. We can assume it is acceptable. (72MHz/36 = 2 MHz CLK --> 125/2MHz = 62,5 us, if I do correct calculation)2- When PSC: 72 and ARR: 77 it should generate an interrupt every 78 us (it is measured 79us with the scope)3- When PSC: 36 and ARR: 155 it should generate an interrupt every 78 us (it is measured 80us with the scope)4- When PSC: 18 and ARR: 311 it should generate an interrupt every 78 us (it is measured 82.3 us with the scope)5- When PSC: 9 and ARR: 623 it should generate an interrupt every 78 us (it is measured 86.5

I'm using an STM32F030R8T6 chip on a breadboard. Everything works fine with Atollic TrueSTUDIO, but I decided to download STM32CubeIDE and create a basic empty project.In the Device Configuration Tool, all I did was enable "Debug Serial Wire" so that I can debug using ST-Link. No user code in the main loop yet. After hitting the debug icon, this is output and I get a break point on HAL_Init()STMicroelectronics ST-LINK GDB server.

I created a fresh C++ project and copied over some existing C files from another project. I then renamed them to .cpp and started porting them. First I renamed the system include files from foo.h to cfoo. With this, CubeIDE complains about cstdint not being found. It compiles the file with gcc -std=gnu11 instead of -std=gnu++14.I tried setting the C Compiler to g++ but then CubeIDE chokes on C files using C++ keywords as identifiers.I also tried renaming my own header files to .hpp (because the error occurs in the header file) but the error message remained the same.error: cstdint: No such file or directory foo.hppHow can I tell CubeIDE to compile the file with the correct compiler?

I'm working on STM32F746 Discovery try to use STemWin. I using cubeMX to gen code for cubeIDE. But i'm stuck, sprintf %f not working. It's return 0x00 and dot instead. For example char str[32];float a = 123.456;sprintf(str, "%f", a);the resultstr[0] = 0x00str[1] = 0x00str[2] = 0x00str[3] = 0x26 '.'str[4] = 0x00str[5] = 0x00str[6] = 0x00Then i try to test whats wrong. I tried to gen a project without freeRTOS and test sprintf %f. And it's work fine.Then i found this http://www.nadler.com/embedded/newlibAndFreeRTOS.html I try to follow this step.·        Exclude from all builds any current FreeRTOS heap implementation, typically something like:·        Middlewares\Third_Party\FreeRTOS\Source\portable\MemMang\heap_4.c·        Add the module ·        heap_useNewlib.c·         I've pr

HiJust started to use the TouchGfx, notice an issue with fonts in the designer.I added a new typographies for a font i want to use in a new project, up to this part no problems. But when introduce a text area in the designer and select the new font, the designer does not render the correct font. The correct font only appears when running the simulator.Is this behavior expected? In this case (since the real font is larger) it becomes tricky to put / align things in the designer since the real font size is different from the one shown.I have attached an image to show it (the left panel is the TouchGfx Designer, the right panel is the simulator).Thank You
