How to change the operation cycle of each server and scanner in iBeaconI want to shorten the transmission interval between iBeacon server and scanner

For the test of 'Vibration monitor' in the SensorTile.box example apps, I made data with 'Vibration monitor Training' and tried to test 'Vibration monitor Comare', but an error message 'SDfile needed for the app not found' appears and I can't run the app.​ ​in USB virtual disk, There are files logged by the App 'Vibration monitor Training'​​​

Hi, Community,​SDMMC3 is not working on STM32MP157F-EV1 board.I'm not sure what's wrong.​I can confirm that SDMMC3_CK/CMD/D0 signals are input and output by osilloscope,but SDMMC_FIFO is empty.The following code is part of the SD_SendSDStatus function in stm32mp1xx_hal_sd.cstatic uint32_t SD_SendSDStatus(SD_HandleTypeDef *hsd, uint32_t *pSDstatus) { : : : /* Send ACMD13 (SD_APP_STAUS) with argument as card's RCA */ errorstate = SDMMC_CmdStatusRegister(hsd->Instance); if(errorstate != HAL_SD_ERROR_NONE) { hsd->ErrorCode |= HAL_SD_ERROR_NONE; return errorstate; } /* Get status data */ while(!__HAL_SD_GET_FLAG(hsd, SDMMC_FLAG_RXOVERR | SDMMC_FLAG_DCRCFAIL | SDMMC_FLAG_DTIMEOUT | SDMMC_FLAG_DATAEND)) { if(__HAL_SD_GET_FLAG(hsd, SDMMC_FLAG_RXFIFOHF)) { for(count = 0U; count < 8U; count++) { *pData = SDMMC_ReadFIFO(hsd->Instance); ★★★NOT REACHABLE!!!★★★ pData++; } } if((HAL_GetTick() - tickstart) >= SDMMC_DATATIMEOUT) { return HAL_SD_ERROR_TIMEOUT

Hi,How to use I2C with BLE , I got return HAL_ERROR when I read/write register data from sensor. Thanks. 

Please suggest me some documents explain about RadioSetRxDutyCycle.Thanks.

Our hardware, based on the ST25DV, needs to communicate with a smart phone and send/receive short bursts of data. I have the FTM already working but we are also looking to use the NDEF protocol so we would be compatible with the iOS/Android standards. I will be glad to hear your professional opinion on this since this is our first NFC project.Thank you,Nir.

Once I generate it. It deletes all the code work I have done.How can I disable that happening.

Hello,I am trying to do this tutorial that I found online for measuring an ADC continuously and displaying the voltage read on an LCD Display:https://www.youtube.com/watch?v=EbWOv_0Lp-UI am not using the same board though. He is using STM32F746G-DISCO. I am using the STM32H7B3I-EVAL board, which has a built in potentiometer connected to ADC1 (PA0_C). It measures the 3.3V and changes the measured voltage based on the potentiometer position. I am trying to enable the ADC according to that tutorial (Starting at time stamp 5:15), he enables Scan Conversion Mode, then goes to DMA Settings, adds ADC1, makes it circular, then enables DMA Continuous Requests and sets End of Conversion Mode to "EOC Flag at the end of all conversions". This is also how his menu looks: Mine, however, is different. I cannot enable Scan Conversion Mode. Only option is disabled. Additionally, there is no "DMA Continuous Request." Finally, the End of Conversion Selection menu only has "End of sequence of convers

I'm trying to use the QSPI interface in Indirect mode to read, write, and erase to an MT25Q Flash chip that is found on the B-L462E-CELL1 development kit.Using the HAL QSPI initilization included in the STM32CubeL4 package, I am finding the interface misconfigured. The IO3 data line idles high, while all others idle low.Additionally, it looks like the QSPI peripheral is using all 4 IO lines for instructions, addresses, and data even though I am specifying 1_LINE in each QSPI command, as evidenced by the number of cycles Are there any known issues with this HAL package?

Hi,I am trying to measure the duty cycle and the frequency of a standard servo PWM signal (50Hz and 5% to 10% duty cycle) using STM32F446. I have configured the timers to be in PWM input mode, and I can read both the frequency and duty cycle. The measurement is very accurate with the 32 bit timers (TIM2 and TIM5) down to sub uS for pulse length. However, with the 16 bit timers the frequency and the duty cycle measurement is very inaccurate. I believe this is due to the prescaler I used. I had to use a prescaler greater than 50 with the 16 bit timers to avoid overflow. However with the 32 bit timer I used a prescaler of 0. Interestingly, it is also very inaccurate when I used the same prescaler on the 32bit that I had to use for the 16 bit timer. Below are some tests I did to measure 50Hz and 2000uS pulse length, the clock frequency to the timer is 84MHz.50 Prescaler -> 51.5Hz; 1960.714uS75 Presclaer -> 50.667Hz,1973.214uS100 Prescaler -> 50.49Hz, 1979.76uS500 Prescaler -> 5

I'm bringing up a new project using STM32F733, with code generated from CubeMX version 6.6.1, with difficulty. Looking for suggestions.1) When I change the HAL timebase source from the default SysTick to something else, I've tried TIM2 and TIM10, then the call to HAL_Init() never returns, it runs out of stack. I've increased stack from the default 0x200 up to 0x2000, still runs out of stack. This is before any of my own code is called, only cube generated code.2) Leaving the HAL timebase source set to SysTick, it steps through ok with the debugger (Segger J-Link). If I add a tight for loop doing nothing but incrementing a variable, stepping through, looking at the call stack, things look normal for a short while. The variable looks like it increments about 1,500 times when I let it run and then the micro starts stepping through unexpected code. The call stack showing nothing but __iar_SB + 0x1fcfed56, example, the offset from __iar_SB increments as it runs.Where should I be looking? Ha

From the datasheet PA0 is listed as a 5V tolerant IO (FT type). Does this maximum of 5V still hold if the pin is mapped to the ADC input? If not, what is the maximum reading for this case?

I'm now trying to blink a LED on my STM32MP157-DK2 board.I have managed to run and even modify the GPIO_EXTI example, but I'd like to do this from scratch.1) I first created a project using CubeMX and wrote my code in the IDE.It seems that I can't use the BSP_LED_*** instructions as the build gives compilation errors : why can't I build my code when using these instructions ? Do I miss an include​ ?2) Then I tried to use the HAL_GPIO_*** instructions. This time, the build is successful, but the debug does not blink the LED.I have seen in the manual UM2367 that the blue LED is connected to PD11, so I try this:HAL_GPIO_TogglePin (GPIOD, GPIO_PIN_11); HAL_Delay (100); /* Insert delay 100 ms */but it doesn't blink. What did I miss?Thanks for your help.

i have set enables 1,2,3 and 4 as 1100 which is address 2 , but for some reason the speaker is not open and voltage is not passing through it which means i cant move on and give orders through i2c registers, can you please explain what the reason might be?

STM32F767 SAI SPDIF Output, NODIV and Clock GeneratorWhen NODIV bit is set in SAIx->CR1, the SPDIF output frequency is as it should be.Example:clock in is 25.6 MHz, sampling rate is 200 kHz, factor is 128, as it should with "symbol rate" (2 channels with 32 bit -> 64) times 2 (biphase mark code).But when the NODIV bit is cleared (MCLK divider is ON), and MCKDIV[3:0] is set to 0000, the clock is divided by 4. (clock in 25M6 -> sampling rate 50k)Why's that so?And why is that not documented? (RM0410, latest)Or what am I mssing?Thanks in advance.

We have custom board design based on stm32157C-DK2. We just ise other LCD panel. We have updated device tree and probe function of panel is called. But in method: ltdc_load it fails to find any panel.bridge when calling: drm_of_find_panel_or_bridge (return -517 EPROBE_DEFFER)Is there something else to check if we want to use other panel please? Thanks.

I'm developing my custom board using a STM32WB55VGY6TR microcontroller and I want to use the Nucleo-WB55 developer kit as a programmer for my custom circuit board.However, I cannot start debugging using STM32cubeIDE. The IDE said that failed to start the GDB server and error in initializing the ST-LINK device.I agree my chip assembly could have a problem, but I feel that the chip is rigidly bound to the board. So, I am pretty sure there is no miss connection.I connected the programming Jumper pin of Nucleo-WB55 to the STM32WB55VGY6TR below.GND => GND of microcontroller (Vss in right-top side)NRST = NRST of microcontroller pin with a 10k resistor, 100 nF capacitor, and Schottky diode. (the circuit is fully same with reset part of Nucleo-WB55)SWDIO => PA13 of microcontroller that is described as "SYS_JTMS_SWDIO (no mode)" in the STM32cubeMXSWCLK => PA14 of microcontroller that is described as "SYS_JTCK_SWCLK (no mode)" in the STM32cubeMXSWO => PB3 of microcontroller that is d

Hi! I'm really new to this world, so I'll appreciate the simplicity of your answers.I have an STM32MP157F-DK2 at the University and I need to measure a voltage signal and an UART signal. Can I use only the dual Cortex®-A7 32 bits for configuring the board pins? Or do I must use the Cortex®-M4?Either way, I'm having problems with understanding all this. I have finished reading the instalation wikis, what's the difference between working with the Cortex®-M4 with STM32CubeMP1 installed, and working with the Cortex®-A7 32 bits with the Linux Kernell?I need to create a GUI that shows the voltage signal an the UART that represents temperature, but I need the pins of the board for detecting those signals.

HiI am a little bit lost on this particular discovery board. I connect it via CN7 (STLink V2 connector), and jumper settings are as supposed. The user guide says that LD6 should be red, and LD5 should be green. LD6 blinks red, and LD5 is constantly green.However, my STLink does not emulate and does not show up in the device manager. STM32CubeProgrammer does not recognize any STLink, either.So even though I am having power attached to my board, the STLink does not emulate.Any ideas what I am doing wrong? Isn't the STM32F103 (the STLink) supposed to be preprogrammed, so that I can flash the actual MCU on the discovery board?Thank you,

I am using a nucleo l4r5zi.​I would like to use the GPIOs on this board as inputs and get the value of those inputs from software.Specifically, I would like to use PG2 to accomplish this.​I have the following setup and am inputting 3.3v into PG2, but for some reason I cannot read the value of the input.​・Pin initilization​static void set_pin(void) { GPIO_InitTypeDef GPIO_InitStruct = {0}; __HAL_RCC_GPIOG_CLK_ENABLE(); HAL_PWREx_EnableVddIO2();   /*Configure GPIO pin : PG2 */ GPIO_InitStruct.Pin = GPIO_PIN_2; GPIO_InitStruct.Mode = GPIO_MODE_INPUT; GPIO_InitStruct.Pull = GPIO_NOPULL; HAL_GPIO_Init(GPIOG, &GPIO_InitStruct) }​・ReadHAL_GPIO_ReadPin(GPIOG, GPIO_PIN_2)Are there any settings that are missing?
