Hello,We have a touchgfx project. I design main screens and write board specific codes to project. My colleauge design some other screens for same project . Is there any way to import his screens to my touchgfx project (with protecting my screens) ?I use import GUI function from touchgfx IDE but it deletes my screen and import his screens. How can I solve this issue ?Regards

Hi,I am trying to interface an I2S MEMS microphone (SPH0645) with the STM32F446RE MCU for keyword spotting application. The mic produces PCM signal. Unfortunately, I have no idea where to start on receiving and processing the data from this MEMS mic. The resource regarding interfacing this particular microphone is hard to find on the internet. Could anyone please kindly guide me on this issue? Thanks in advance.

I selected the LQFP176 package, because the datasheet expresses a 32bit data bus. However, ST development tools are limiting me to 16bit. Has anybody taken the generated 16bit code and expanded it to 32bit or would I be wasting my time? Thank you for any feedback.

Why did they use such a strange new design for the ST-Link interface on this Nucleo board?The "older Nucleo/Discovery" ST-Link-Target connector (6 pin, e. g. CN11 on the Nucleo-LQFP64 boards) is missing.There is some "strange new mini size MIPI connector there" ... really very ugly with its 1.27mm design ... should this be the new world replacement? And then were is the 2x jumper block to switch between internal and extrenal target connection?... and somehow the schematics of this Nucleo board is not complete ... if I try to check the SWDIO line in this schematics, it is marked only exactly one time, at the target H723 uC there ... but the other end seems to be missin.... at least Adobe find function does not find it... .Maybe these STM32H730 / STM23H723 chips have some different new debug interface? (Is it possible to connect to these chips with the older style discovery / nucleo board st-link interfaces?).PS: Nasty side question: Why do they always place this Ethernet interface on th

Good day, I'm trying to interface the STM32F401RE with a DS3231 RTC module. The idea is to read from the time-keeping registers of the RTC module. Based on the code, I decided to set the 'hour' register to 6 and when the register is read, 6 is expected to be read. This code only works while single stepping in debug mode and not at runtime. I don't know why this is happening but if there's something I'm missing or getting wrong, I'd be glad to know. The source code is in the attached file below.

HelloI am basically designing an interrupter for plasma arc speaker. I have a small signal amplifier which I connect to STM32F746 and perform FFT to determine which note was played. Whole process takes about 2ms. My transformer works with 25khz. I want to turn it off and on again on the note frequency I want to play. For that I need to implement PWM repetition mode.signal will look like thisHowever I am not sure how to do that without software and making unnecessary delay to turn the timer off and on again. What is the best option to save processing time and achieve this kind of signaling ?

Hi,do you know if the STM32H745I-DISCO Board will ever be supported by TouchGFX. Or is there already an easy way to use TouchGFX with this board?

Looks like the Scheduler, SCH_*, have been replaced by the Sequencer, UTIL_SEQ_*. Does anyone know where there is detail description of the Sequencer, along with examples?Thanks,Mark

Hi,I need to write some data in the flash memory of my STM32H743ZI MCU, for example serial numberCan I write this data in something smaller than a whole flash sector ?Regards,Gabriel

I have set the jumpers as per the demonstration video for the device but I cannot get the in-built apps to activate. I am wanting to utilise the DAC input for the microphone and an ADC output for the headphone jack. I can only assume the in-built applications will not operate until programming software has been uploaded to the device.Please can anyone advise if I have the right pin configurations set. Is pins PA1 and PA5 for the microphone and pins PB6 and PB7 for the headphone jack?

Hello, I'm having troubles with a library in CI've made a library named "LedControl" divided in "LedControl.h" and "LedControl.c"So far the header file is like this:#ifndef SRC_CUST_LEDCONTROL_H_ #define SRC_CUST_LEDCONTROL_H_         #define LC_POINTER_LIST_LEN 255       // VAL1 VAL2 END ON/OFF TR1 TR0 PWMv FLOAT 32 CHANGE uint8_t WORD_IT[] = {0x00, 0x01, 0xFF, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}; uint8_t WORD_IS[] = {0x03, 0x04, 0xFF, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}; uint8_t WORD_TWENTY_MINUTES[] = {0x0D, 0x0E, 0x0F, 0x10, 0x11, 0x12, 0xFF, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}; uint8_t WORD_TWENTYFIVE_MINUTES[] = {0x0D, 0x0E, 0x0F, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0xFF, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}; uint8_t WORD_FIVE_MINUTES[] = {0x14, 0x15, 0x16, 0x17, 0xFF, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00};   //[... more array definitions]   void LC_transitionIn(

Using a STM32F091.I was thinking whether one could detect certain kind of boot / power issues where the VDD would be briefly interrupted, by buffering the VBAT with a sufficiently big capacitor, separated by a diode with low Vforward from VDD, so the cap won't get sucked dry by the rest of the circuit when VDD fails.Is this a common thing to do / makes sense? (given that the system cannot have a battery to permanently power VBAT)I also wonder what happens when I write to a backup register and inmidst of it, VDD fails.Is there a way to make use of the backup registers to detect boot loop / power instability issues reliably? Garbled register content would not help so much.I was thinking of a scheme like this to deal with that:I use 2 of the backup registers as a double buffer (i.e. for each next frame, the other one of the two gets written) for a time value (that I get from a connected I2C total runtime counter chip). I use a 3. register as an index as to which of the two is the cur

For a given application I am trying to control the main loop speed thorugh the ADC sampling rate. My objective is targeting a fast embedded control application so I plan to go in the 100kHz-10MHz range (yes, I am aware of the STM32H7 limitations for GPIO manipulation at high loop frequency). Relevant parts of my main.c are: MX_GPIO_Init(); MX_ADC1_Init(); MX_ADC2_Init();   HAL_ADC_Start(&hadc1); HAL_ADC_Start(&hadc2);       while (1) {   g_MeasurementNumber++;   GPIOE->BSRR = (1<<1); //set to high while((ADC1->ISR == (0<<2))){ //wait for EOC }; g_ADCValue0 = ADC1 ->DR;   while((ADC2->ISR == (0<<2))){ //wait for EOC }; g_ADCValue = ADC2 ->DR;   GPIOE->BSRR = (1<<17); //set to low 1+16 }There, GPIOE registers are manipulated for generating a signal I can easily measure in the oscilloscope. ADC1 and ADC2 are configured for continuous acquisition with data override, and values i

I have a product using a 14-pin STM324 MZ79017—I am unable to find any technical literature on this IC. What type of component is this?

Hello,I was reading the reference manual of the STM32F091, in particular the RTC chapter.Then I looked at what the CubeIDE generated (set all to LL, not HAL) init code does.So it has this function SystemClock_Config() where all clocks are configured.There it :enables backup access (set DBP in PWR->CR)resets the backup domain (setting and then clearing BDRST in RCC->BDCR)sets the clock source to HSI (RTCSEL bits in BDCR), as I don't have an external clock crystalenables RTC (set RTCEN in RCC->BDCR)From what I took from the manual, 2. will clear the backup registers.So if I want to use them, among other things, as a communication method between an application and a bootloader, I need to modify that to not do that - if I determine, well, what exactly?That's still unclear to me.Will any part of the RTC stuff still be enabled after a sysreset / or even power off/on (while VBAT was still buffered)? I.e. can I check any of the register flags to determine that I do not need to do the

Hi, In the evaluation board of SPV1050 (STEVAL-ISV020V1), it is mentionned that the maximum voltage from the PV cell (VMP) is to be equal 9V, but there is no indication about the absolute values that I can be supported without damaging the board. I'm working with a PV cell having an open circuit voltage of 9.6V with a voltage at the maximum power point of 9.2V. Would you think under these conditions, the evaluation board will be damaged ? Thank you for your reply.Georgina

I have Pololu breakout containing a LSM6DS33 connected to a ESP32 module via I2C. INT1 is connected to GPIO15. I am driving Activity and Wake Up to INT1. The ESP32 picks up the interrupts reliably. I would like to know whether the LSM6DS33 is active or asleep after having received the interrupt. I read the WAKE_UP_SRC register to see the source of the interrupt. However, it almost always returns only FF_IA bit and Z_WU, and nothing other. I do not drive Free-fall to INT1. It returns the FF_IA bit even if the device is still. This is driving me crazy! I attach the simplified Arduino Sketch to help troubleshoot the problem.Your help would be much appreciated.Ben Zaaiman

Hello @Houssem CHAABANI​ ,Is there a setting with STM32CubeMX to change the Tick Init Priority value? I observe that example FreeRTOS project (generated with help of STM32CubeMX) have macroTICK_INT_PRIORITYset to 0xF, while the code generated with help of my IOC file has the macro set to 0.Please help.Thanks,Rajeev

Evening,I have been working on a FreeRTOS project for the last six months and all was going well until the last STMCubeIDE & CubeMX update.Rightly or wrongly, I have been using the usarts with the below interrupt config  /* UART8 interrupt Init */  HAL_NVIC_SetPriority(UART8_IRQn, 0, 0);  HAL_NVIC_EnableIRQ(UART8_IRQn);Preemption = 0.After the last CubeMX update, my four uart comms no longer worked.After much digging, I found that the CubeMX was setting the Uart Preemption = 5, thus generating the below code. /* UART8 interrupt Init */  HAL_NVIC_SetPriority(UART8_IRQn, 5, 0);  HAL_NVIC_EnableIRQ(UART8_IRQn);When it is set at 5, my code no longer works. The uart interrupts do not respond at all.A value of 5 appears to be a reasonable value or even in the range of 5..15.Why does my code no longer work??P.S. I used the CubeMX builder for the original project design and used it's defaults.It would appear that all  Preemption's

Hello,I'm creating application with STM32F072, with ADC DMA, USB, Timers and Uart.Last one is used to communicate with PC but i verify a strange behavior.First of all general information:generating this software with STM32cubeMx. using IDE openstm32priority level USB = 0priority level TIM3 = 1priority level DMA = 2priority level UART = 3The strange behavior is present when i'm debugging application for checking uart peripherals. I sent chars from MCU to PC, when these chars arrived on minicom see chars differets.When PC sent chars to MCU, MCU goes in error for noise.This happend in debug mode.In Run mode ( same configuration debug) this behavior not is present yet.Can you explain what i missed?Thank you in advancedAndrea
