Solved

Hi everyone,I am having the biggest of issues when it comes to getting the MCLK on the STM32 working with a FWS = 192kHz.I followed the Clock generator cheat sheet in the reference manual and still not working.The SCLK and FWS are working perfectly as I can measure it with an oscilloscope, but when it comes to the MCLK the signal is so faint which is where I presume the issue is coming from.I have tried other FWS modes such as 96kHz and it works perfectly, even the MCLK signal is most more noticeable to be seen on the oscilloscope.What's going on? The only difference in master mode from 96kHz to 192kHz is just "DIVP" 8 to a 4. So I dont know whats causing such issues. CODE:void init_I2S_Inline(int * RxBuff_inline, int * TxBuff_inline){   //Setting Clock for 192kHz //N = 122 //P = 4 //M = 10 //FRACT = 7209   // RCC_PLL2DIVR // MASKING: RCC -> PLL2DIVR &= ~RCC_PLL2DIVR_P2; RCC -> PLL2DIVR &= ~RCC_PLL2DIVR_N2; // WRITING: RCC -> PLL2DIVR |= RCC_PLL2DI

Hello to all.I'm coding an I2C comunication and the IDE (1.4.0) create the Private variable I2C_HandleTypeDef hi2c2; and then the function MX_I2C2_Init. Everithing ok.I'm using an external .c file to handle the I2C communication and how can I access to the hi2c2 from my read/write functions in my .c module?Thanks in advance, Manu.

Hi,I cannot import existing project into Workspace.

Datasheet of STM32WB55 mentions that the Maximum voltage that can be given to VBAT is 3.6 V. But, it is also said that there is an internal voltage divider so that voltage to the ADC is 1/3 of the voltage at the VBAT pin So, is it possible to connect 4.2 V LiPo battery to VBAT pin for voltage monitoing?

Hi, I'm working on Stm32CUBE IDE with STM32LO71RB. I would like to write a version number when I am flashing my device at EEPROM Flash memory address 0x08080000. I've tried HAL_FLASH_Program(), but I have to execute it at each reset. I would like to do the same as an One-time programmable memory but it's not availlable in STM32 cortex M0+. Is there any other possibilities to write directly in EEPROM memory? best,

Is it possible to group open tabs in the CubeIDE by the projects they belong to?If I have two projects open at the same time it becomes pretty confusing which source file belongs to which project.

I need to know how to write some code to simply transmit a continuous modulated signal for compliance testing.

We have a custom board which have a ST25R95 transceiver with a PCB copper made NFC antenna/coil that is double side. Now we want to switch to ST25R3911B transceiver to be able to reach a higher reading distance for NFC tags. We do have some bare boards to make tests with the antenna/coil alone.When I calculated the components for RF circuit of ST25R95 through a spreadsheet, it was required to input only the inductance and the DC resistance values. But for ST25R3911B there are other inputs like "Parallel resistance" and "Self resonance frequency". This is required by the tool "ST25R Antenna Matching Tool" in order to calculate the values of components for the RF circuit.The "Parallel resistance", should it be measured at 13.56MHz or other given frequency?And about "Parallel resistance" and "Self resonance" parameters, which kind of equipment could be used to measure them? Regards.

Hi,I'm making a new prototype based on the design/layout of the NFC06A1 evboard with minimal differences as for example : I don't use the capacitive electrodes in my design for wake up feature (but I put test points to CSI and CSO pins).And I want to get through CE/FCC certification, but before I have to do some pre-compliance testings for the device. Therefore I have some questions regarding the NFC part.1- The NFC06A1 design (st's) is already NFC compliant and has FCC & CE certifications I guess. Do we need to redo any testings for this part of my final product ?2- How can I access to (RF) test mode in the ST25R36 if I need it? I just saw in the datasheet test access but I cannot figure out how to do that?3- What are the important points that we should verify in pre-testing process?Please see the schematic capture below (any observations ?): Thanks in advance,

Under SBSFU, I am able to run my custom application, and everything run fine. But changing the SFU defualt UART.with USB throughing error "USB Device not recognize!!!", I debug through SBSFU code, and USB stack(CDC and Devi ce only Configuration) initialize correctly.I will highly appreciate for any help.With regardsJitu

HiI'm currently using STM32H743 and I'm trying to Read Data in multiple GPIOx_IDR registerPreviously, I was using 16 bits and trying to change into 32 bits for IDR.When I debug, I could find correct data on SFRs -> Register -> GPIOA -> GPIO_IDR with below code.previous codemain.h#define my_data_Pin (0xFFFF) // Use all PA0-PA15 pins#define my_data_GPIO_Port GPIOAotherfile.cvoid read_my_data(uint16_t *pbuf){*pbuf++ = (uint16_t)my_data_GPIO_Port -> IDR;}Now, I'm not sure how to define the code for using all PA0-PA15 pins & PB0-PB15 pins for 32bit data. I've tried something like below, but it didn't work.#define my_data_Pin (0xFFFF) && (0xFFFF)#define my_data_GPIO_Port GPIOA && GPIOBCould somebody help me out with this please?Your help will be highly appreciated.

I've been using Ecosystem v2.0 without any issues now. We decided to move to v2.1 recently, followed the instructions from https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package to get the latest package. Then, as I did before, followed the instructions from https://wiki.st.com/stm32mpu/index.php/How_to_create_your_own_machine to create the distribution for our custom board. But running bitbake-st-image-weston failed because it could not create project.dtb as the project.dts files were not copied from the meta-st-stm32mp-addons folder to their respective folders in tf-a, u-boot and kernel.Has anything changed in v2.1 with regards to custom device tree file placement?

Hi,STM32 is working very well with the Windows application ST Motor Control Workbench Monitor. I want a interface document or manual for the serial communication which is happening between the STM32 and Control bench application. So that I can use the same communication protocol for master controller to interface with the BLDC driver controller instead of PC application.Regards,Nishanth M

Are there pins which enable external operation of the pushbuttons, the Black (Reset) and Blue (User) pushbuttons?Where is their operation described (and what are they named in that document so I can search for the details in the document)

If I tick the enable box in STM32CUBEMX the interrupt is enabled when MX_GPIO_Init() is executed. Since this is prior to the initialisation of FreeRTOS queues etc this turns into a disastrous mess.If I leave the box unticked then everything assoociated with this interrupt must be written manually.It's a shame that the interrupt can't be setup in the MX and then manually enabled when the appropriate FreeRTOS task becomes active.

Often I call the C function from the hardware in Model::tick() function. But how can I call the function of Model outside.If I add a member variable to get the Instance(this) of Model, is there any risk? I mean if Model writed by Singleton mode.

I am using the MCU STM32H750VBT6 and I am trying to configure the ADC1 to take readings from a sensor, but I am not using DMA, only that the DMA is not returning the correct value to me, it would give me an example code of how to read a ADC1 channel? Also what settings are used?

Hello,I'm back with some new questions! Thanks for always being helpful... here we go.From within a class that I have extended the Container object, I am unable to simply use my object as such:application().getCurrentScreen()->getRootContainer().add(myObj);then my compiler throws this error:no known conversion for argument 1 from 'modalBase*' to 'touchgfx::Drawable&'If I try the same thing with a custom container that I created from within TouchGFX designer, I can compile just fine, and the code works as expected.I am extending the Container object just as TouchGFX does:class modalBase : public touchgfx::Container { public: modalBase(); virtual ~modalBase() {} virtual void initialize(); protected:   private: }

So I started a Project in CubeIDE with the standart settings and the resolving integration issues Video.All worked well. But now i enabled LwIP with standart Settings and I get the Error, that the SDL2/SDL_video.h File in the HALSDL2 Header couldn't be found. But shouldn't this File be excluded from the Build? How can it throw a Error in there?Also if i restart CubeIDE and build again, sometimes i get a lot of errors in the TouchGFX/Simulator Folder, which also should be excluded. If I disable LwIP again and restart CubeIDE it wil work again.Versions:CubeIDE: 1.0.1TouchGFX: 4.10.0MCU: STM32F746G-DiscoverySincerly,Kevin
