Hello,I have a container that is present in every single view (namely a header that contains a clock).I need this header to read 12h/24h time setting, and then draw time accordingly.If I use Model-View-Controller, I must implement activate() method in every single Presenter to load this setting from Model, and implement "setTimeSetting()" in every single View, which will call the container "setTimeSetting()". This is a bit overkill, isn't it?So instead of that, I just implement the function in FrontendApplication, and call it in the container only using application().getTimeSetting().Is it appropriate to store a global variable in FrontendApplication instead, that the container reads directly? Am I missing something here, is there going to be problems with that?To me, this seems to be easier approach in most cases, and less risk of typing errors when making lots of function calls between M-V-C objects.Thanks!

For my first foray into the STM32 world I've been trying to get to read nfc tags with a STM32L475 and ST25R95 custom board. It is taking me a while to get used to the CUBE IDE, since including libraries many times results in errors, specially since I'm coming from the Arduino IDE.As the title says I'm trying to adapt the included polling example(for the L476 board) to work with a custom board based on the STM32L475. I'm using the SPI2 port which I have inited in the main code, (pins PB12-PB15). I have made the changes in platform.h and st25r95_com.h to change hspi1 to hspi2. But still I always get initialization failed... any more places I should be changing SPI1 to SPI2?Thank you for your time.

Also uVision 5.29 generates a bunch of Font missing .cpp file errors? Is there an install guide I'm missing?

I purchased two different ST controller boards:B-G431B-ESC1NUCLEO-G431RB and X-NUCLEO-IHM16M1I also have two motors:MIGE 80ST-M04025MIGE 130ST-M10010I've tried to profile the motors using the ST Motor Profiler but it always errors with "Profiling takes too much time" at 94% of Electrical parameter detection. The exact same thing happens with both controller boards and both motors. I've tried different combinations of voltage, current and max speed. The motors have 4 pole pairs.I also tried gathering the information from the datasheet (https://hzmgdj.en.alibaba.com/product/60120702270-200533488/SERVO_MOTOR_OF_80ST_M04025.html) and run the motor in Workbench but I cannot get the motors to run smoothly. They just rapidly move back and forth.Any help would be greatly appreciated.Here's an example of the parameters I've tried:

Hi everyone,I would like to know if is possible to add STM32F030K6 MCU at ST Motor Control Workbench. If it is possible, how can I do this?

Hello,I am new to NFC solutions and want to design a product that can read tags for 40cm distance with ST25R3911B , could you give me some suggestions ? And how to adjust the antenna driver output resistance (register 0x27) to match the impedance,also what is the suitable value for the capacitive voltage divider?​Thank you very much for your help. Best regardsSky​

Hi, how to add program to autostart in OpenSTLinux ?I tried adding initialization script to /etc/init.d and creating .desktop file in ~/.config/autostart directory, but nothing works.I will be very gratefull, if somebody could help me.

Hi, Is there a way to take screenshots on the STM32MP157C-DK2? thanks in advanceLukas

Hello,Is it possible to monitor local variables using STM32CubeMonitor?

Anyone know if the MCWB will include hall sensor control sometime soon? I don't see anything and the various documents are out of date and contradictory.

Not sure where to post this, just unpacked a STM32MP157C-EV1 and was following the Getting started instructions. The insctructions use USB to program a SDHC card. But, on this page:https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-EV1/Let%27s_start/Populate_the_target_and_boot_the_image"Connect USB Type A to Type C cable between PC and CN7/USB_OTG port of the STM32MP157x-EV1 board"But CN7/USB_OTG is on the STM32MP157C-DK2, not the -EV1 and there is no corresponding connector (I think). Will try to program the card using ST-LINK.Thanks!

Hi, how can I disable the autostart of the demo-application on the STM32MP157C-DK2 and make my own application autostart ?thanks in advanceLukas

When I tried to do it in STM32CubeProgrammer I receive the next error:18:37:09 : OPTION BYTE PROGRAMMING VERIFICATION:18:37:09 : Error: Expected value for Option Byte "SPRMOD": 0x0, found: 0x118:37:09 : Error: Option Byte Programming failed

I am using stm32G031K8 nucleo board. The board was working well, it started to reset itself continuously for some time, I could only see my uart message that says started, every time I erased the code and upload previously working versions. Then it started to not execute code, now I upload led blink project but still doesnt work. I can erase the flash then upload new code.When I try to debug it, run button is passive at the beginning.When I press the reset button registers filled with 0xffff.It cant go to reset handler at the beginning, how can I fix it? Thanks.

I started a project from scratch in CubeMX. and the set TouchGFX for portrait as :Middleware->Graphics->TouchGFX, changed width : 272 and Height : 480. In TouchGFX designer it displays correctly as Portrait(see PortraitFromTouchGFX).PNG) but when I compiled using IAR and deployed it on the target bd, it doesn’t display correctly (see From STM32F746-Disco Display.jpg )In Hal.hpp : It automatically sets the display orientation based on width/height, so I don't think I need to do anything else.

Hello, I am trying to write a simple hello world in order to make printf work with my setup. I have an own board, which I am programming it using ST-Link V3set (I also couldn't get it to work with ST-Link V2). I can program my board, debug it, I can see variables on live expression and everything is working perfectly. The problem is when I try to redirect printf to ITM. I overwrite the _write function, I can step through it, I can see it writing to the register, but I get nothing on my console. I basically followed this video and have also tried following articles, where everyone got it working. I have followed every possible step, but I still don't get anything on the console. What am I doing wrong?

Hello! I have 2 projects for two different controllers: one is the STM32F767 and the second one is the STM32H753. I'm using the Cube IDE 1.3.1.I have noticed , that when I generate a code, the the file structure looks different for both of them even when I try to ise exactly the same drivers.For example when I use GPIO and LTDC, the for the STM32F767 I get such a structure (looks better for me):And when I generate the code for the STMH753 then I get such a structure and the initialization functions are directly in the main (not optimal for bigger projects):My question: How to change the automatic code generator to use the same way of working like for the STM32F767 (modular code)?Regards,Gregor

Hi to all!I'm new to STM32, so i want to learn. I have a Nucleo-STM32F767ZI board and i try to interface this board with the MPU9150 sensor via I2c. The problem is that i can't able to communicate with the sensor. Using a logic analyzer i see that the board get-out the SDA and SCL signals, but the sensor answer with a NACK. Also If i use a read operation, i see the correct slave address (0x69) on the logic analyzer, but if i use a write operation i see a wrong value of the slave address (0x68).I use the STM32CUBEIDE to generate the project, and i use a default configuration for I2C1 with no filters enable, rise time and fall time set to zero. The output pins are mapped to the PB8 and PB9. Please, someone can help me to find where i'm wrong?

Hello,I am assigning pins on a STM32F446 micro in cubemx.I would like to give a pin name to NRST, but it is stuck in a reset_state, and won't let me change it. It is colored differently than other pins.Is it possible to change NRST, or does it stuck like that to signify that it is the reset pin? Still going to use it as the reset pin, but not sure if that has to be specified somehow. I have the same exact issue with the BOOT0 pin. Is it possible to change the BOOT0 pin?

Hi,I am trying to use the PA2 and PA3 Pins among others as Inputs with Pullups. The configuration is correct, since I am comparing what is in the GPIO Registers for Port A with another input pin PA8 which works fine. I have seen that the same pins use serial and analog input, however I have not initialized serial and I guess to use the analog input you have to initialize it in the mode register? I am using the ADC but I have not configured these pins for analog input.Am I missing something, that is keeping me from using these pins?

Hi there,My application is battery operated, so I’m trying to wake up atmega328p from deep sleep from an interrupt though the GPIO pin from the sensor. I'm using Thresholds, "inside window". If any object ditected inside the range, to fire a trigger to wake up the host. Is such thing possible?If yes, could you give me some pointers or code samples please?My host platform is Arduino Pro Mini @ 8Mhz 3.3v.Thanks!

I need to get some PCBs made by JLC but they are continually out of stock of the STM32H743IIT6 which is my target processor. They do however have the STM32H753IIT6. Is there any reason I can't substitute these to run identical firmware?Thanks

Hi,Master:​​Platform: STM32F301K8U​As shown below in Figure 1, PA7 (MCU_14) is a video signal (As shown below in Figure 2), which contains the line sync signal (A area in Figure 2, fixed frequency, there may be noise)​and the field sync signal(B area in Figure 2). I want to distinguish the line sync signal and the field sync signal . My question is as follows:Question 1: What is the purpose of PA4 in Figure 1 through capacitor to ground and PA2, PA3 short circuit?Question 2: I want to use the comparator to compare PA7 and DAC1_CH1 and then use the input capture to measure the period to distinguish between the two signals (As shown below Figure 3). Is it feasible? I worry that if there is a lot of noise on the PA7, it may be difficult to distinguish. Is there a better solution? Ask the master for advice.​Thank you very much!​​ Figure 1 ​ Figure 2​ Figure 3
