Solved

Thank you for your help

I am using SPC560B microcontroller, I want to program in such a way that the module should produce a wakeup interrupt ever 0.1S once. What is the value to be loaded in RTCVAL field in the RTCC register for 0.1s interrupt.I have used a clock source of 128KHZ. So, to get the 0.1s interrupt the RTCVAL loaded 12800void ConfigureWKPU(void) { /* Enable WKPU PCTL */ SPCSetPeripheralClockMode(69, SPC5_ME_PCTL_RUN(2) | SPC5_ME_PCTL_LP(3)); INTC_PSR(46) = 7; WKUP.WRER.R = (1U << 1);                    // enable wakeup pin of:\n WKUP.WIREER.R = (1U << 1);                   // enable rising edge interrupt  WKUP.WISR.R = 0xFFFFFFFFU;       // clear interrupt flags that an external rs WKUP.IRER.R=0xFFFFFFFFU; WKU

@Imen DAHMEN​  Still looking here for a small-footprint solution in the stm32g4 line with hardware SPI flash (QuadSPI) handling. The WLCSP versions of the STM32G4x3 and STM32G4x4 lines might be viable. They are slated to be released in Q1 2020 (that is, by the end of March). In light of the covid-19 situation, is this release timetable still accurate?

Hello,I am trying to make SPC560B54L5 EVB in low power mode that is STANDBY mode.The measured current in normal RUN0 mode is 143 mA whereas while keeping in STANDBY mode, it is around 92 mA. But as per the AN3316 Application note the max current consumption is 314uA. So am I entering into STANDBY mode correctly?Because I could see that USB is getting disconnected during waiting for the S_MTRANS to SET. while (ME.IS.R == 0U){  ; }How can I make sure rather SPC560B54L5 EVB is in standby mode or not?

I am trying to setup the ADC channel on PA0. I have first set the pin mode to additional function. Then I have followed the examples provided in the reference manual. However, it doesn't turn on anything, either the calibration or the enable. It is not even selecting channel 0. Am I missing something or did something wrong? This is my ADC related code below:int main()   {   //Set PA0 to Additional function mode   GPIOA->MODER |= (3 << 0) ;   //Ensure ADC is Disabled   if ((ADC1->CR & ADC_CR_ADEN) != 0)   ADC1->CR &= (uint32_t)(~ADC_CR_ADEN);     //Start ADC Calibration   ADC1->CR |= ADC_CR_ADCAL;   //Wait for ADC Calibration to Complete   while ((ADC1->CR & ADC_CR_ADCAL) != 0)  { }   //Wait for TIM14 is Enabled //TIM14 is used as a forever interrupt loop in my while function as a clock while ((TIM14->CR1 & TIM_CR1_CEN) == 0) { }   //Select TIM14 by writin

Hi, ​I'm developing an application with freertos that starts from the address 0x08004000 instead of the standard 0x08000000, because at the start address I have a bootloader but I'm not able to debug the application. I changed the VTOR offset to 0x4000 in the startup file generated by the internal cubeMX, and I also added the following line in: startup - "Initialization Commands" of the debug configuration set *0xe000ed08 = 0x4000   set $sp = *(unsigned int*)0x4000   set $pc = *(unsigned int*)0x4004   tbreak main​I'm using jlink or in alternative stlink_v2 but nothing changes. The code is loaded always from address 0x08000000. Someone could help me? These settings are enough to debug a freertos application? Thanks in advance

part number: STM32F779BII am using clock frequency 108 MHz ( not system clock , system clock is 216 MHZ)I don't want to use loopif not possible what is the maximum value i could set using timer

I want to configure timer of 10 millisecondsso for that according to calcuationUPDATE Frequency = TIMCLK / ((PSC+1) * (ARR+1))   My clock frequency is 108 MHzso when i set prescaler is 107 and ARR value is 9999 it should be updated frequcy is 100 Hz which is 10 millisecond timerbut i am not getting desired output hereDipak Garasiya

I use online antenna design that provide from ST website. After i input some parameters i needed, then click and download design file. i cannot open in Altium PCB design by using import wizard. Is there any special program requires?

Hi,I use st25r3911 ev board with rfal on X-NUCLEO_NFC05A1.​First I tested below project in NUCLEO-401RE that I don't have any problem.But, I switched target board to NUCLEO -F429ZI that I have an interrupt problem.​​The problem that after an interrupt pin is not go low.As I know, after occurring interrupt and I read the interrupt register. And interrupt pin to go low.So, I insert delay for work around like below picture.And I add my project.​

HI all, I am Ragu, and I need to flash SPC560b50l5 chip using SPC560b54l5 discovery board. I use PLS adapter setting in document as they mentioned but it not works?. Below I attached JTAG connection circuit diagram which I use. I probe the JTAG pins with CRO and I confrim that data transfer is takes place from spc560b54l5 discovery board but spc560b50l5 controller is not respond after flashing. I need to know why it is not works. I think it maybe not flash correctly, isn't it? I any one face this issue, Please help me.With Regards,P.Ragu.

Hi, I'm evaluating on the STM32F3DISCOVERY board using STM32CubeIDE but I'm having trouble interfacing with the onboard E-compass. In the Device Configuration Tool, I've enabled I2C1, since the user manual states that the MCU controls the E-compass via I2C. However, when I try to read data from the E-compass using HAL_I2C_Master_Receive(), it always returns HAL_ERROR. Furthermore, when I call HAL_I2C_IsDeviceReady(), the E-compass never returns that it is ready? Below is my relevant code: void I2CTask(void* argument) { uint16_t CompassAddress = hi2c1.Init.OwnAddress1; uint8_t CompassData[255]; uint16_t CompassSize = sizeof(CompassData); uint32_t CompassTimeout = 200; HAL_StatusTypeDef CompassStatus; init_printf(NULL, putc); // Wait for compass to be ready while(HAL_I2C_IsDeviceReady(&hi2c1, CompassAddress, 64, HAL_MAX_DELAY)!= HAL_OK); for (;;) { // TODO: Debug compass read error CompassStatus = HAL_I2C_Master_Receive(&hi2c1, CompassAddress, &CompassData[0], Comp

I am porting a code written for the stm32f4 to stm32l0. The code uses the ll diver to configure USART1 with the following statement:LL_AHB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_GPIOA)The LL_AHB1_GRP1_PERIPH_GPIOA value is not defined for the STM32L0. Where can i found more information on the clock configuration?BRGilberto

Hello,I'm trying to connect SDRAM to STM32 for the first time and I'm having trouble understanding the specs.In the datasheet, it seems the FMC peripheral can support 32bit memory.But when I use the Cube MX setting, I'm only able to select 16 bits for the Data.Is there something that I'm missing in the data sheet?

I have a project based on an Stm32F767. If I load the hex file and then manually enable readout protection to level 1 with the STLinkV2 utility, the board fails to begin to execute code after reset. Why? What is the correct way to use this feature?

I have built a custom container (TextInput) where the user can enter a string of fixed length. It is relatively similar in structure to the existing Keyboard ContainerWhen the maximum string length is reached, a second custom container(TextValidation) becomes visible and shows the entire string, divided into several text boxes. If the user now clicks on a textbox, the TextValidation container should become invisible again and the substring should be available for modification in the TextInput window.Currently I have a public method setText in the TextInput class, which calls setWildecard.In the TextValidation container, after a button click, the getParent method is called, the drawable object is casted to a TextInput and from this the setText method is called.I am relatively new to c++ and probably there are much better ways to solve this problem.What is the recommend way to resolve this problem?

My question here is this: Can the STM32G4x1 line access external flash memory (e.g., via QuadSPI)?My confusion is as follows: the following page:https://www.st.com/en/microcontrollers-microprocessors/stm32g4-series.htmlintroduces the STM32G4x1, G4x3, and G4x4 lines. In the table (at the center of the page), Quad-SPI (for accessing external flash memory) is listed in the left column as a common feature across all three of these lines.In addition, the slides athttps://www.stmicroelectronics.com.cn/content/ccc/resource/training/technical/product_training/group0/42/95/f2/b1/78/5c/49/55/STM32G4-Memory-QuadSPI_interface_QUADSPI/files/STM32G4-Memory-QuadSPI_interface_QUADSPI.pdf/_jcr_content/translations/en.STM32G4-Memory-QuadSPI_interface_QUADSPI.pdfindicate that "The Quad-SPI memory interface integrated inside STM32G4 microcontrollers provides a communication interface, allowing the microcontroller to communicate with external SPI and Quad-SPI memories".

Posted on September 07, 2017 at 03:03HI,I'm currently test the STM32F429 Disco kit with some example on step by step.But I nerve that LCD always turn on, So Is there any way to turn off the lcd ? because I'm not ready to test the LCD.

Hello,For an end of study project, I use a STM32L073RZT6 MCU.I made an STM32 / Breadboard adapter. Like that : Now, I would like to program this MCU. For this, I was given a ST-LINK / V2. I used the MCU and ST LINK datasheet to make the following connections:I then used the ST LINK software to try to connect, impossible!I tried several things, with the BOOT, Reset .. But nothing helps.I checked the pins, but absolutely nothing.Did I forget something to keep it from working?

Im can not set SNSINC-bits from MACSSIR Sub-second Increment Register. Other Bits like SSINC I can set without problem ! (STM32H745XIH6U Discovery Kit ). Look like a Bug ?

Hi all,I am using the  ST25R3916 Discovery GUI to communicate with an NFC03 board in CE mode and so far I have been using the ISO14443A Tab and Debug tab to exercise the functionality. I have a few questions regarding the GUIIs there an updated or more detailed manual/documentation on the GUI -- the hosted version doesn't contain information regarding the ISO-DEP tab.What is the difference sending out a command via the ISO-DEP tab vs the Debug Tab.Can somebody point me to the firmware section that processes/interfaces with the GUI across the different tabs, fields and buttons?Is it possible to rebuild the GUI with some additional functions or buttons? Some additional functions that I would like to have is to be able to send a large chunk of data which then will be parsed into multiple frames and get sent across and likewise receive multiple frames and reparse them back into its original form.Would appreciate a PM if that would be easier for communication, thanks!!

Hi everyone,I am student who is new to STM32. I am trying to understand how to program the MCU and noticed GPIO_InitTypeDef data type. I went into the reference manual but did not find anything about it. Is there a document including all the functions a user can apply to the STM32 (and hopefully find information on GPIO_InitTypeDef) ? Thank you in advance.

According to product page X-NUCLEO-IHM03A, this motor driver voltage range should be between 10.5 V to 85 V. But I got a sample I do see Vin max printed as '50V'. Can someone from the nucleo explain which max voltage spec I should choose?
