Solved

Dear ST Community,   I need to use an SRAM with the STM32H743AII6 MCU. When I try to configure the project on CubeMX, a warning appears next to the FMC line. I feel like I should fix this before going further with the configuration. I am curious why I am getting this warning even when FMC is the only peripheral that was already configured. Has anybody experienced this before? Are there any suggestions to resolve this? Here is a summary as background information: The warning text says "Partly disabled conflict with FMC Chip Select NE1". Warning stays even if I use NE 2/3/4. The package is UFBGA169, and NE1 pin is available on that specific pinout. CubeMX version is 6.11.0 but the issue was present with earlier versions as well. A screenshot is attached below. Thanks, JD

Hi,Hope this is a simple question.I use this device: STM32H753ZIT6I don't intend to use USB so looked in the datasheet and found the belowDoes that mean I can safely connect VDD33USB to GND?Thank you. 

Dear experts,  I have worked with the SPI of  SPC563 without any problem before. Also, I checked the example of the SPC564 and I am not seeing any differences. now I am trying to config the SPI of a SPC564A70 myself. When I monitored the chip select pin with osciloscope, I saw that the logic of CS pin is inverted. meaning that it is low all the time and when I send the message it becomes high. I also checked the inactive state of the pin in configurations and all of them are "inactive high". can you help me regarding this issue? Thank you

Hi Everyone, I'm working with a SPC570S discovery board. I uploaded a code with my SPC5-UDESTK debugger and the codes were successfully uploaded. But suddenly I couldn't upload any code using that, and its green LED still works. But I tested the same code with another similar SPC5-UDESTK debugger and it worked. I checked my SPC5-UDESTK debugger with other development boards also. Unfortunately, it is not working but its green LED is working. Please help me to sort this issue out.Thanks Yohan 

Good Day,I've been experimenting with transitions on TouchGFX. I'm not a huge fan of the 1990's style transitions that come out of the box, and wondered if I could define a transition myself with custom behavior. Basically, I want sections of my screen to slide off in different directions before going to the next screen.Using the transitions already defined as an example, I was able to use the Snapshot widget to do what I want to do, but I'm currently unable to compile, as the transitions that come with designer are declared in `FrontEndApplictionBase` which is generated code.I guess I'm not looking for a hard and fast solution here, but more just asking the open-ended question of, "has anyone else tried/succeeded in doing something like this?" I'm also open to suggestions of better solutions, but I really like the idea of this clean implementation.Thanks,Jack

Hello! I bought the development board for SPC560B! When using SPC5STUDIO programming software, I found that I don't know how many functions defined in C language are defined! I just want to ask if you have explanations for the initialization definitions of functions such as clocks, SPI, interrupts, etc., so that I can understand them better! Also, is there any documentation and a summary of common problems related to the programming software SPC5STUDIO that I would like to learn and use!Thank you!

hi community,can I use  "SPC5-UDESTK-PLUS" for flashing and debugging for "AEK-AUD-C1D9031", which contain"SPC582B60E1" microcontroller. Regards,Shiva

Hi all,I'm trying add FPU exception to my project and I'm bit confused because two sources points two different interrupt vectors for this. Book E says, FPU exception is under IVOR33 but SPC58xH manual points IVOR10. And SPC5Studio libraries have "decrementer support" under IVOR10. I suspect SPC58xH is right for me but I want to be sure.  regardsMichal

Recently started working on the L9026 Device,  as an initial setup, trying to read the Device ID.   With The L9026 Evaluation board Device ID is read as 0x55, With L9026 Placed on the Our Target Board, Device ID is read as 0x56,  Was surprised with the response of Target Board, Would you please us, what is the Device ID expected for this Chip and How it is programmed? Quick response will be greatly appreciated.

Hello,Just a clarification question. When going through the application note (AN5248) for ST25R95. It mentiosn at one point there is a maximum allowed voltage on RX1 and RX2 which should be below 7V.Where in the datasheet is this specified? Thank you. 

Hi,We're using the STM32 HAL layer(STM32G0xx_HAL_Driver v1.6.1) for I2C and see that when re-enabling the I2C listen interrupt, the HAL_I2C_ListenCpltCallback is called twice. This results in that the first I2C read cmd works but the second after that fails.Our callback:void HAL_I2C_ListenCpltCallback(I2C_HandleTypeDef *i2c_handle){ if (my_i2c.state == MY_I2C_STATE_DONE) {   my_i2c.state = MY_I2C_STATE_RX_ADDR;   HAL_I2C_EnableListen_IT(i2c_handle); }}The reason for this seems to be that we're calling HAL_I2C_EnableListen_IT from interrupt/HAL context.What seems to happen in I2C_Slave_ISR_IT are these calls:1. I2C_ITSlaveCplt(5036) -> HAL_I2C_ListenCpltCallback(6173) -> our function above2. our function above -> HAL_I2C_EnableListen_IT3. I2C_ITListenCplt(5053) -> HAL_I2C_ListenCpltCallback(6256) -> our function aboveWhat happens is that function in 2 above changes the HAL internal state to:hi2c->State = HAL_I2C_STATE_LISTEN whil

Bug DescriptionSTM32CubeMX offers the user an option to register their own callback functions under the advanced settings tab:In this example i have enabled the callback registration for CAN aswell as the SDADC. After generating the code my stm32f3xx_hal_conf.h file looks like this: ... #define USE_HAL_ADC_REGISTER_CALLBACKS 0U /* ADC register callback disabled */ #define USE_HAL_CAN_REGISTER_CALLBACKS 1U /* CAN register callback enabled */ #define USE_HAL_COMP_REGISTER_CALLBACKS 0U /* COMP register callback disabled */ #define USE_HAL_CEC_REGISTER_CALLBACKS 0U /* CEC register callback disabled */ #define USE_HAL_DAC_REGISTER_CALLBACKS 0U /* DAC register callback disabled */ #define USE_HAL_SRAM_REGISTER_CALLBACKS 0U /* SRAM register callback disabled */ #define USE_HAL_SMBUS_REGISTER_CALLBACKS 0U /* SMBUS register callback disabled */ #define USE_HAL_NAND_REGISTER_CALLBACKS 0U /* NAND register callback disabled */ #define USE_HAL_NOR_REGISTER_CALLBACKS 0U /* NOR register callbac

I'm having an error where i get not such file or directory in an include but the file is there exactly where its located in the project that that touchGFX generates for my boardAnd while reading the documentation I saw that In Project manager, the option generate code under root should be off, and I thought maybe this was the cause, but I don't know, The thing is i can't disable this option, it appears in grey and i can't disable it, I get that I can't change the structure of an already created project, but even if i create a new project by doing new--> STM32 Project, when the .IOC files open some files are already created and I can't disable it either. I'm using STM32CubeIDE.

Spoiler (Highlight to read)  Hi, I have a question about the size of the flash of STM32G0J6. When i use STM32 cube programmer - CLI i saw that the size of the flash of the STM32G0J6 is 64Kb. I try to write everywhere in this memory it works. The datasheet say that the STM32G0J6 flash size is 32Kb and when you look at register 0x1FFFF75E0 it says that the flash size is 32Kb. Is it  normal ?

I'm new to TouchGFX and I'm trying to use a toggle button to send a data frame to a car display via the FDCAN bus using STM32 microcontrollers. I'm not sure if it's possible to achieve this functionality with TouchGFX and STM32, and if it is, I'm unsure where i  configure the filter, transmit header, and add messages in the main.c function!! If anyone has experience working with this setup, I would greatly appreciate any guidance or assistance you can provide.

MCU = STM32L433RCTxSTM32 CubeIDE version - 6.8.0I'm working on sd card operation using sdmmc 4-bit mode but it is not working. but when I select 1-bit sdmmc mode so it is working as well.I want to know how can I resolve this issue. my sd card connector is MSD-4-A and there are all line connected with 47k pullup resister leaving CLK pin.SDMMC Init -hsd1.Instance = SDMMC1;hsd1.Init.ClockEdge = SDMMC_CLOCK_EDGE_RISING;hsd1.Init.ClockBypass = SDMMC_CLOCK_BYPASS_DISABLE;hsd1.Init.ClockPowerSave = SDMMC_CLOCK_POWER_SAVE_DISABLE;hsd1.Init.BusWide = SDMMC_BUS_WIDE_4B;hsd1.Init.HardwareFlowControl = SDMMC_HARDWARE_FLOW_CONTROL_DISABLE;hsd1.Init.ClockDiv = 4;there are lots of post available related this issue but can not clear proper solution. In some post there are talking bug in firmware in latest version. if yes so how can I resolve it.Thanks in advance.

Hi all,I have a simple project using a STM32C011J4. Using STM32CubeIDE V1.15. I compile it for both Debug & Release.I program it via STM32Programmer V2.10.The Debug elf file works okay, however, the Release elf does NOT run…Yes! I have checked that the Debug & Release files are up to date (and time)...Yes! The NRST pin is correct level…What else should I check?Kind regardsPedro

Hello, I would like to use the offical VScode extentention together eith STM32CubeMX.The guide says I need to set up MX generator Toolchain / IDE to Cmake.However I have no such option: How could I use the extention with CubeMX?I remember the option was there about a year ago on a different MCU (F3).I have STM32F103C8.Thank you!  

I have implemented a hallinterface (tim 1), to update my pwm timer (tim 8). But the delay i set is rather fluctuating.Disabling interrupt inside of the tim 1 interrupt did not help. And i think, outside of the interrupt it should not matter, since this is only hardware that is not influenced by software really? At least i would not think that it should fluctuate in a scale of about 2us. Init of interfacing timer 1: /** * Timer for hallsensors (Rotor speed for FOC later) * Delayed execution of interrupt comes from filter!!! */ void initHallTim1AndDriverTim8(){ __disable_irq(); __HAL_RCC_TIM1_CLK_ENABLE(); SET_BIT( TIM1->CR2, TIM_CR2_TI1S); // config all 3 hall signals (PC0-2) via XOR to timer 1 WRITE_REG(TIM1->ARR, 0xFFFF); // Max value (is reset by input signal) WRITE_REG(TIM1->PSC, TIM1_PRESC - 1); // Mind the 1 that is added in the uC ! SET_BIT( TIM1->CCMR1, TIM_CCMR1_CC1S_0);// | // TIM_CCMR1_CC2S_0); // channel is configured as input,

Hello,I'm working with STM32H7A3, STM32CubeIDE Version: 1.14.1 and TouchGFX Designer 4.23.2.If I add a simple button to my project, when I press the button on the touch screen I see the image change but the buttonCallbackHandlerdoes not trigger, while if I add for example a toggle button the callback triggers correctlyI attach part of the code generated by TouchGFX Designer.void Working_menuViewBase::buttonCallbackHandler(const touchgfx::AbstractButton& src) { if (&src== &toggleButton1) { //Interaction1 //When toggleButton1 clicked execute C++ code //Execute C++ code static int i; i++; } if (&src== &button1) { //Interaction2 //When button1 clicked execute C++ code //Execute C++ code static int i; i++; } } class Working_menuViewBase : public touchgfx::View<Working_menuPresenter> { public: Working_menuViewBase(); virtual ~Working_menuViewBase(); virtual void setupScreen(); protected: FrontendApplication& application() { r

I would like to know the working principle of the charger bump for MH98, as well as the working principles of CPOUT, CP1, and CP2. Why can the voltage of the bootstrap capacitor reach 11.3V when VDH = 6V? In other words, why can the voltage of CP reach VDH+11.3V?
