Hi everyone,TouchGFX Version: 4.19.0STM32CubeIDE Version : 1.9.0Card : STM32F429I-DISC1OS: Windows 10HAL: STM32F4 1.25.0I have created a TouchGFX project, rename in all ioc , touchgfx and project file the project name give by touchgfx.I have keep the HAL use by touchGFX 1.25.0When i compile first in CUBE IDE it's compile and run well on card, but when i regenerate code with the ioc in CUBE IDE i get a lot of compile error.I would like to be able to update the .ioc for a custom card that will have an Ethernet and many other features.What i have done wrong ?Thanks in advance.arm-none-eabi-gcc "../Middlewares/Third_Party/FreeRTOS/Source/queue.c" -mcpu=cortex-m4 -std=gnu11 -g3 -DUSE_HAL_DRIVER -DDEBUG -DSTM32F429xx -c -I../../Core/Inc -I../../Drivers/CMSIS/Include -I../../Drivers/BSP -I../../TouchGFX/target -I../../Drivers/CMSIS/Device/ST/STM32F4xx/Include -I../../TouchGFX/App -I../../Middlewares/Third_Party/FreeRTOS/Source/CMSIS_RTOS_V2 -I../../TouchGFX/target/generated -I../../Middleware

Hi, I have tested my 4.3" TFT-LCD by write the whole screen with one color blue or orange freshing with about 34hz, but it blinks.the test code run in main function:  int ii=0;  int cl =0x0;//color  while(1)  {   if(ii==0) {  ii =1; cl =0xFF00; }else { ii =0; cl =0x00FF; }  LTDC_Clear(cl);//change the sceens color. HAL_Delay(30);  }​the clock of tftlcd is 10Mhz, and its resolution is 480*272, LTDC_Clear() runs DMA2D to freshing data like this: CS_UINT32 timeout = 0; DMA2D->CR = DMA2D_R2M;  // dma2d mode: register to memory.  DMA2D->OPFCCR = DMA2D_OUTPUT_RGB565;  DMA2D->OCOLR = color;  DMA2D->OMAR = (CS_UINT32)addr;  DMA2D->OOR = offsetLine;  //offset  DMA2D->NLR = (CS_UINT32)(xSize << 16) | (uint16_t)ySize;     DMA2D->CR |= DMA2D_CR_START;  while (DMA2D->CR & DMA2D_CR_START) 

I'm using the LTDC peripheral to interface with a TFT LCD. It works great. Now I'm interested in rotating/orienting the display by 90 degrees. I have a couple approaches in mind - Doing some pointer gymnastics into the frame buffer that basically writes the pixel information into precise addresses that results in a "rotated" image. Somehow tell the TFT LCD panel to start writing the pixel information from the bottom to the top of the display. Instead of the default top to bottom.I'm open to other approaches or maybe I'm missing an obvious way to do this. Maybe leveraging the 2 layers that the LTDC makes available? Somehow have one dedicated for landscape the other for portrait mode? I am not using the touchgfx library since I'm only interested in displaying still images and it looked to be more helpful for applications with UI's.I'm researching the 2nd approach. Page 15 of the ILI6480BQ data sheet states that there is a register R1 in the TFT LCD driver that controls the scan direction

When STM32WB is used as slave device, how to actively disconnect Bluetooth connection of mobile phone?

Hello,I was creating a new project for STM32WL in STM32CubeMX today, and I wanted to use the "register callbacks" functionality for a timer peripheral. So I have enabled the callback feature and generated the project. When I opened it the symbols for callbacks were not defined. I started digging around and found out that the symbol **USE_HAL_TIM_REGISTER_CALLBACKS** was set to value **1** in the *stm32wlxx_hal_conf.h*. But this header is not included in the *stm32wlxx_hal_tim.h* so callbacks enumeration is not created. The *stm32wlxx_hal_tim.c* is including the *stm32wlxx_hal.h* so the register/unregister functions are created correctly.Am I missing something? How the HAL driver can work if the structure defined in the header file does not contain callbacks definitions?Sorry if someone already asked, but I couldn't find any topic that addresses this.Best regards,Tomas.

When I run this code, the value stored in colourBuf[0] changes after the for loop at line 73 completes. The colour0 value doesn't change.

Hi everyone,I can not get SPI using the DMA to work. The MOSI line stays zero all the time. The result is the same using my own and also the example code provided with the firmware package for the MCU (STM32CubeL5\Projects\NUCLEO-L552ZE-Q\Examples\SPI\SPI_FullDuplex_ComDMA_Master).On the other hand, if I use a busy transfer (HAL_SPI_Transmit(&hspi1, aTxBuffer, BUFFERSIZE, 100);) the MOSI line outputs data as expected, which makes me believe that on the SPI, GPIO side things are working fine.I guess there must be some configuration that I am overlooking. Still, it surprises me that the example is not working.Any ideas?

I am having trouble getting the TIM1 timer on the STM32F413VG chip to output PWM to pin PE9. My configuration and code in STM32CubeIDE can be seen in the attached images. Have I done something wrong? Every example I have found out there skips TIM1 and goes straight to TIM2, could it be that TIM1 does not support PWM generation, even though it is an option in CubeIDE?

HI! I have a L4960 switching regulator, I want to know if there is a formula to calculate the switching frequency in fuction of the resistor and capacitor connected to pin 5. Also if you know more information about the pin 3 and pin 6 functionalitys it will be very helpful. Thank you.

I am stuck trying to get the STM32L552E-EV evaluation board running with SPI using the DMA. Neither the mentioned example (STM32CubeL5\Projects\NUCLEO-L552ZE-Q\Examples\SPI\SPI_FullDuplex_ComDMA_Master) nor the code created via the wizard, nor my own code work. I end up always with the same problem of the SPI clock running and also the HAL_SPI_TxRxCpltCallback function getting called, but the MOSI line staying low (see figure). At the same time, transmits triggered via the HAL_SPI_Transmit function are clocked in just fine. I posted a question to the same topic before, but I guess the title was not descriptive enough, and I did not mange to draw further attention to it. (https://community.st.com/s/question/0D53W00001uaQ9aSAE/spi-using-dma-not-outputting-data-on-mosi-line-on-the-stm32l552eev-evaluation-board) It would be great if someone (maybe at ST) could try to run the example on the mentioned evaluation board and check if it is working fine. At the same time, I am open for any advic

I'm using an ST MCU (STM32F765VGT6) on a custom board, wired to an X-NUCLEO-NFC06A1 communicating via I2C. I've integrated the RFAL library into an existing codebase. I've taken elements of the Disco demo code into our codebase, to exercise the RFAL. (It is based on the PollingTagDetect example, demo_polling.c, from STM32CubeExpansion_NFC6_V1.1.0)I am able to detect a tag, but the UID is returning as blank. I'm not seeing any I2C traffic on the Saleae analyzer that looks like the ID, so I don't think it is being retrieved from the reader. The code isn't breaking anywhere that seems to write to nfcId1, but it's a little hard to track down which variable it's actually stored in. Can you point me to where in the RFAL library you'd expect the nfcId1 variable to be stored for a NFCA type 2 tag? For I2C are there any gotchas similar to the SPI gotachas (where you need to have a separate GPIO controlling CS)? Any other suggestions for tracking this down? Thanks,Katie

Hello I am using nucleo G031K8 with STM32 cube ide and I am trying to initialize the SPI1 peripheral with registers.Here is my init code and the corresponding wrong registers. The RCC and GPIO registers are fine. Only SPI1 registers are wrongHow can I solve this?Thanks

I know the microcontroller has built-in comparators and I'm trying to use it as a transimpedance amplifier. So, I want to test the comparators but the Necleo-WB55 developer kit doesn't have built-in comparators. So, I have to test it on my custom board with the STM32WB55VGY6TR microcontroller.However, there is two big concern.The one is that I didn't connect any output pin of the comparator to ADC in my custom board.The other is that ADC cannot read negative voltage but the transimpedance amplifier is inverted OP-AMP. So, the output could be negative.So, I have a question here.Is there any way to read the comparator's output voltage without connecting the output pin to the ADC? (or is the microcontroller designed already for this purpose? because I found that it is not mandatory to assign the output pin in STM32cubeMX.If not, can I connect the output pin to the ADC even though the comparator may generate a negative voltage?
