Hi I would like to know whether the interface is cubic-bezier left in touchgfx.I noticed that there's a little bit less description of the easing equation .Thank you.

Hello,I try to play a sound using stm32h747i_discovery_audio.c. Initialization goes well void CAudioController::AudioOutInit() { BSP_AUDIO_Init_t audioOutInit;   if (!audioOutInitDone_) { audioOutInit.Device = AUDIO_OUT_DEVICE_HEADPHONE; audioOutInit.ChannelsNbr = 2; audioOutInit.SampleRate = AUDIO_FREQUENCY_44K; audioOutInit.BitsPerSample = AUDIO_RESOLUTION_16B; audioOutInit.Volume = 50; if (BSP_AUDIO_OUT_Init(0, &audioOutInit)!=BSP_ERROR_NONE) { while(1); } audioOutInitDone_ = true; } } But first call BSP_AUDIO_OUT_Play callBSP_AUDIO_OUT_Play(0,playBuf,1024);ends up in the default handler. It is a bit strange but while debugging the program jumps to the default handler either from HAL_DMA_Start_ITcall or from __HAL_SAI_ENABLE_IT(hsai, SAI_InterruptFlag(hsai, SAI_MODE_DMA));inside BSP_AUDIO_OUT_Play().The BSP_AUDIO_OUT_Init() initializes Sai and DMA. Does anybody have a hint in which direction to look for the root cause?Best Regards,Anton

Hi, I would like to know the current consumption of a LSM6DS3 with it's accelerometer and gyroscope running at 52 Hz and 104 Hz. The LSM6DS3 will be powered by a 2.8V source. Are there any official numbers or documents available for this?

Hi supporter, I installed the STM32CubeIDE v1.3.0 on my macos. After install success, I try to debug example project. The console window show "stm32mp1x.cfg can not found".

I am trying to interface another cpu to ST25RU3993 EVAL using the serial port. what are the serial port settings? baud rate 3000000, 8N1, RTS_CTS on ? Can i change the baud rate without uploading new firmware to the board?

Posted on February 21, 2018 at 13:01Hi;I have a problem.I want to be output pins PC14 and PC 15, so make the registers PWR -> CR = 0x00000100, RCC-> BDCR = 0x00000000. probably  LSE ocillator isn't off. thim my code :#include 'stm32f10x.h'#include 'stm32f10x_gpio.h'#include 'stm32f10x_rcc.h'int main(void){PWR -> CR = 0x00000100;RCC-> BDCR = 0x00000000.;RCC_APB2PeriphClockCmd(RCC_APB2Perirh_GPIOC, ENABLE);GPIO_InitTypeDef control;control.GPIO_Pin = GPIO_Pin_14 | GPIO_Pin_15;control.GPIO_Mode = GPIO_Mode_Out_PP;control.GPIO_Speed = GPIO_Speed_2MHz;GPIO_Init(GPIOC, &control);      while(1){                  GPIO_SetBits(GPIOC, GPIO_Pin_15);          GPIO_SetBits(GPIOC, GPIO_Pin_14);      }}How can do this ?Thanks,

Hello!Dear ST technician!Using the chip STM32L476 +3993 provided by your company and the original code provided by the official,I have encountered a problem of operating tags. I sincerely consult you here:When the tags of GB29768 is inventory,In tag memory, read from area:Read operation of coding, Tag Information, Security, User,"Could not read tag..." Warning, unable to operate,Compared with gen2 tag, the above functions can successfully perform read and set operations,detailed reading of the source code, see a complete preparation of GB29768 tags operation procedures,the ST25RU3993 Reader Suite also feels perfectly functional,So I'm glad to consult you, could you tell me what caused it?I wish you good health!ST loyal user

Hello, I could not infer from the datasheet that ST25DV04K could be used at fast mode I2C speeds (400 kb/s). The datasheet states "Two-wire I2C serial interface supports 1MHz protocol". The datasheet does not mention compatibility with other I2C speeds. I want to confirm that the IC will work for I2C@400 kb/s operations smoothlyThanks,Eshwar

Hello, I would like to know in detail how exactly does the Engineering mode work on this platform. The information at https://wiki.st.com/stm32mpu/wiki/STM32CubeMP1_development_guidelines are kind of vague and a little confusing. Is the Cortex-A7 being used in this mode at all, or it goes straight to an infinite loop? Where is the secure debugger running, if the A7 is not used? Is the ROM code executed by the Cortex-M4? The figure shows that the debugger runs on the Cortex-A7, which technically means it also loads and runs the co-processor firmware, so it can not go into an infinite loop?

Hello,I am trying to read some NFC tag with a X-NUCLEO-NFC03A1 attached to a NUCLEO F091RC board. I am a beginner into those technology, so basically I was trying to load the sample "NFC Detect " from the package "X-CUBE-NFC3" wich can be found on ST official website to understand how to use NFC stuff. The problem is, I tried to build the project on the STM32 IDE Cube, and it worked fine, but i can't read anything on the NFC NUcleo's antenna after running the programm. I suppose there are problems of initialisation , but i have no idea how to debug this. Thanks you for your time,Best Regards,Karim

Dear all, I am using SAI in STM32H7 to control an external audio codec. Everything works fine except the fact that when I look at the actual sampling frequency (SAI FS signal ) I measure 45.5kHz rather than 44.1kHz as specified in the init. The clock of the SAI is 128M. Do you know what i should look at to get the closest frequency possible ?

Can I use only the TX and RX pins of an USART and make it work exactly as an UART?

Hardware Setup: MCU: STM32L496ZG (Nucleo- L496ZG board) connected to ST25R3911B over SPI, tag is ISO15693 compliant Software: Using the rfal library and the iso15693 APIs in en.STSW-ST25RFAL001 (V2.1.2)IDE: Atollic TrueStudio V9.3.0Is it possible to use non-blocking SPI drivers to create an RFID comms interface using the ST25r3911B and STM32L496 MCU?So far I have successfully implemented RFID comms using blocking drivers that involve using the `spiTxRx` function in the platform.h file and calling the `st25r3911Isr()` in the ISR for the INT pin of the STM32L496.But what happens if I have non-blocking SPI drivers that implement a state machine to handle SPI transactions and is not a single function call like `spiTxRx`? How do I modify the `platform.h` file and use the rfal in that case?Does the ST25R3911B support RFID comms using non-blocking SPI drivers?

Hello,After copying an STM32CubeIDe project using the New → Project from .ioc file and then importing old project version into the one, the IDE wont let me program the device.With old project version, I can run the programming Run settings and the STLinkV2 reflashes the MCU.With the new project version, STLink cannot find the device.The Run settings are the same...Any suggestion ?Thanks.s.

Hi,i want to add a transition animation when the animation is over,i know the  Animated Image contain a callback name setDoneAction(), but i want to realize like H750 demo,when the button is clicked,the fan is still turn for a moment and then stop, i want to do that.what should i do in the code?Thanks.

I was wondering how I can measure a pulse duration that is greater than the timer resolution of 16 or 32 bits. More specifically, I would like to record the absolute timestamp of captured input pulses on multiple timer channels. These timestamps can then be used to calculate the intermediate duration. My feeling is that this is a common timer application but I can only think of a rather complex solution. Below I will describe my solution with a STM32F302CB MCU and HAL drivers. Because it requires both HAL driver modifications and race condition detection, I am curious if there is a simpler solution for this.Absolute timestamp calculationSince the timer period is too small for my application with the desired frequency, my idea is to combine 'input capture' and 'timer update' events. When HAL_TIM_IC_CaptureCallback() is called for a particular channel, the absolute timestamp is (TIMx_Overflows * (htim.Init.Period + 1)) + HAL_TIM_ReadCapturedValue(htim, channel), where TIMx_Overflows

Hi,Can anyone help me identify what ST component this is? It's used in an R/C transmitter I have, it's not old, built in 2019...But I cannot figure out what ST Micro part this relates to?I found the 'STUSB1600', but that doesnt seem to fit with the design in this circuit, and also the circuit design doesn't line up with how it's wired on this board..Thanks so much,Mike

Hi,We are facing a lot of problems with the SPI communication with an ST25R95 device. We are using as a main CPU an Silicon Labs EFR32MG13 with the next configuration: config.master    = true;      // master mode config.baudrate   = 1000000;      // CLK freq is 1 MHz config.autoCsEnable = true;      // CS pin controlled by hardware, not firmware config.clockMode  = usartClockMode0; // clock idle low, sample on rising/first edge config.msbf     = true;      // send MSB first config.autoCsHold = 1; /** Auto CS hold time in baud cycles */ config.autoCsSetup = 1; /** Auto CS setup time in baud cycles */For example, if we send the next stream of bytes in order to execute an echo command:{0x01, 0x55, 0x03, 0x03, 0x02, 0x03}We receive the correct answer only if we stop th

Hey there,I have an STM32F042K6 with 32 KB flash which works with a whole bunch of peripherals using STM32 HAL and a lot of code. Now that everything is configured, it is overflowed by nearly 1.5KB (region `FLASH' overflowed by 1464 bytes).What I'll need to do is a significant reduction of code size. I've already turned on all optimization flags -Os, -fmerge-all-constants, -ffunction-sections and -fdata-sections. What else do you do to reduce the code size?Active peripherals:ADC1, I2C1, SPI1, DMA for SPI1, Timer 2, Timer 16, DMA for timer 2, UART2, USB CDC as VCPI'm not using any (emulated) floating point and no division at all which saved a lot of space already, but 99% of the code feels like is taken away by HAL.Thank you for your help.
