Solved

I have a project where I want to place the TGFX resources (images, translations, fonts) in a memory mapped QSPI flash. In this instance I have placed them in this flash via the linker (.o files) rather than using binary fonts etc. The crash occurs generally when switching screens. I can usually switch screens successfully a number of times. Sometimes it fails after 30 screen switches, sometimes 5. I've also seen it fail when updating smaller elements. The crash also prevents the debugger (IAR / I-Jet) from stopping, so I've had no luck there. Debug log: "CPU did not stop"I find the problem goes away if I put the TGFX fonts back in internal flash. It also goes away if I switch back to full frame buffers rather than using partial frame buffers. ( I have restrictions on ram usage, so partial frame buffers are needed)I've given the TGFX FreeRTOS task lots of stack but that doesn't fix the problem. I put a scope trace around the TouchGFXHAL::flushFrameBuffer(const Rect& rect) routine. I

The prototype of the generated function by STM32CubeMx when using FATFS is:int32_t MX_FATFS_Process(void) This cannot be used with FreeRTOS as a task entry function since it has the wrong return and argument type. The function prototype should be :void MX_FATFS_Process(void *argument)So that it could be accepted while creating FATFS task: FatFsTaskHandle = osThreadNew(MX_FATFS_Process, NULL, &FatFsTask_attributes); In the example project provided in STM32Cube MCU Package for STM32L5 series, the function prototype is correct. The code generated by STM32CubeMX does not match this example.

I want to implement writing of data on password-protected NFC 25 tag) ST25DV04KIn my case, I have enabled write protection on Area1 with password 1 set using the NFC tap App.I want to use a known password to enable my Android and iOS to write the data on these tags.Could you please point ot to the example or resources to implement this feature?

Hi everyone ! After successfully launched ST25R3911 (in 14443-A smart card reader mode) without RFAL , using only analysis of dialog on ST25R3911B-DISCO there was a need to implement an 14443-A emulator based on ST25R3916. With the DISCO everything is easy : logic analyzer, datasheet, and a week to learn and reproduce control commands for ST. The result is a sequence of instructions and register values to implement read mode, sleep mode and so on.ST25R3916 it’s difficult here, let’s say I’m not friends with RFAL in the context of integration into my project and I don't have access to something like DISCO for 3916.The Q is : in which document can I find a sequence of commands using RFAL or register values / direct commands and algorithm for implementing the emulation mode ?

Hi thereIs there a way to have one ID with different Fonts?I don't see the point in generating the same string multiple times with different fonts. That is event cumbersome with the translation offices who have to translate the same string multiple times.We use a lot of the same strings in different places in the GUI.For example I get a String ID from a TCP/PI packet and want to display it on the screen.The sender of the packet does not care which font / typography is used, but I do, so with our old GUI library I could do something like "show_text(TEXT_ID, FONT_A_30px)"How can I do that with TouchGFX? Is there a workaround?Thanks,jimmii

We have to make minimal changes to parts of the HAL code, which would be overwritten by code generation.Is there a recommended way to implement such changes, such that they don't get reverted by generation?The two ways I can think of both have their problems:patch the firmware pack files (i.e. in our case the extracted stm32cube_fw_g0_v151.zip files). This way, the changes would be part of the generated code. This would have to be part of the workspace setup for each developer, and would have to be repeated when the pack is updated.patch the generated code after generation. This would be an additional manual step after code generation. Lacking a "post-generation" hook (see my other post), this is easily forgotten by developers.Is there anything obvious that I'm missing to achieve modifying the HAL code?

I'm working on a project with a STM32F407 using the STM32Cube Ide.I'm trying to add a new library (coded in ANSI C) that manages Zigbee frame encapsulation https://github.com/digidotcom/xbee_ansic_library. My problem is that in some files of that library there are includes such as#include <endian.h>that are not present in the GNU tools for STM32. From what I see, this kind of system libraries are in the following path:STM32CubeIDE_1.4.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.0.202111181127\tools\arm-none-eabi\includeWhat I'm trying to do to fix this is to download the original GNU endian.h library and add it to this path, but I have 2 problems arising from that:1) There are conflicting declarations between the GNU libraries and the IDE libraries, because, the GNU libraries are not exactly the same as the GNU tools for STM32. This throws hundreds of compile errors.2) This way of fixing it will only work in my current

We have a project where, due to various issues found during development, I've modified the PCB layout and changed a few pin allocations.Is there any way to include multiple configurations from CubeMX and select between these at compile time?This would allow us to gradually transition from the old hardware to the new rather than having to upgrade all units to the new PCB before we can release any software updates.It's something I've done many times in the past on the PIC where I/O was configured in the code, but as it's all handled within Cube for the STM32 it isn't as obvious how to achieve it.

I am trying to create a 50ms timer using the above reference. The clock is 16MHz, I have a divisor of 16 and have the NVIC enabled (all this is done in cubeMX). I have the following ISR void HAL_LPTIM_AutoReloadMatchCallback(LPTIM_HandleTypeDef *hlptim) { hlptim1.Instance->ISR |= (LPTIM_ICR_ARRMCF | LPTIM_ICR_CMPMCF); }Prior to the while 1 loop I call:HAL_LPTIM_Counter_Start_IT(&hlptim1, 50000);It doesn't appear to me to be working correctly.....At start up I get into the ISR and count is way less than it should be....Can someone tell me what I am doing wrong? This should be pretty simple as I just want the timer to count to 50ms (using 16mhz with /16) and every time it rolls generate an IRQ.... 

I have a short strip of tape that's supposed to be LSM6DS3's, but the SMD marking code on them is different from the other tapes I have (which where correctly organized and labeled). So, is there a table where I can look up the codes that refer to the LSM6DS3 to find out if these chips are indeed what they're supposed to be? I tried looking for this info in the datasheet and product info page but could not find anything...Thanks!

I have set the clock for the ADC to 51.2MHz by PLL2P with the DIV set as seen below. Without reprogramming the STM32H7A3 I would like to change DIVN2 to x16 and DIVP2 to /32 to give me 4MHz clock to the ADC, but I can not seem to find where these are set in the code.I Have checked the auto-generated code within main.c and there are no options for x32 and /5. Are DIVN2 and DIVP2 set outside of main.c, and if so where?Also is there anything else I need to know/do when changing the clock division via the code?Thank you for any helpCurrent clock configuration that is uploaded to the microcontroller, but DIVN2 and DIVP2 will needed to be changed.

If so, can you tell me what LCD you targeted?

Hi, I have STM32F407 and trying to write log file (in main loop) with FATFS R0.12c over SDIO. But after few writes I get error:FR_LOCKED // (16) The operation is rejected according to the file sharing policyPreviously I was using STM32F103 and was writing to log file using same algorithm with FATFS R0.11 over SPI without this issue. So I suspect the issue should be in "FATFS R0.12c" or "SDIO"?What could be the issue and how could I fix this?

Hello STM32 Community.I need your support, I am trying to do a small project where I need to use for example a var where PWM frequency is saved, as I need to calculate the period I just write a division 1/test_float and the result must be the period.... but the result is zero...I am using a Blue pill board, STM32F103 and STM32Cube IDE.I run this small example in order to show you my issue. float test_float =0; test_float = 1/10;    // ====> test_float=0 test_float = 1/1000;   // ====> test_float=0 test_float = 1/10000000; // ====> test_float=0 test_float = 0.0000001;  // ====> test_float= 9.9999999999999995e-008  that is OKWhy first four lines are equal to zero?, last line (test_float = 0.0000001; ) it has the right value ...100 nsany comment/advice is welcomeregardsAlfredo

Hi,I am using STM32f413zh i build the code in release mode. After that i put break points on inside the code some places, None of the break point is hit. But i flash the binary file the code was running. Please give guidance for hit the code on main() or inside the code.Thankyou.
