I use M24C64-R eeprom. If power is cut off during its write cycle, the data in writing address will become corrupted. In the other hands, will the data out of writing address be kept or become corrupted too?

Hello,Can we generate analog output from MLC instead of a statement? If we can, could you explain how to do it? I plan to use MLC output as a part of my control algorithm. What is the most efficient way to achieve this?

Hello ST electronics,I wanted to know if there are any implementation of T= 1 protocol available with cube MX configurations.Please do let me know.Regards,Adarsh T R

Dear @KDJEM.1 when I read the manual "rm0432" It is given thatThe Flash memory programming sequence in standard mode is as follows:1. Check that no Flash main memory operation is ongoing by checking the BSY bit in theFlash status register (FLASH_SR).2. Check and clear all error programming flags due to a previous programming. If not,PGSERR is set.3. Set the PG bit in the Flash control register (FLASH_CR).4. Perform the data write operation at the desired memory address, inside main memoryblock or OTP area. Only double word can be programmed.– Write a first word in an address aligned with double word– Write the second word5. Wait until the BSY bit is cleared in the FLASH_SR register.6. Check that EOP flag is set in the FLASH_SR register (meaning that the programmingoperation has succeed), and clear it by software.7. Clear the PG bit in the FLASH_SR register if there no more programming requestanymore.My code isuint64_t data=0x1234567890ABCDEF;HAL_FLASH_Unlock();HAL_FLASH_Progr

I modified the LoRaWAN_End_Node sample program for measuring the external pulses input to the COMP1. I register a task in the sequencer and set up the timer in timer server. It is no problem to run a test task by just toggle the LED. When I initialize the lptim1 timer to count the external pulse, the program jump to the while(1) loop in Error_Handler. Checking by breakpoints, it is because the LPTIM_WaitForFlag function resulted HAL_TIMOUT. Below is the code of lptim1 initialization.void LPTIM1_Init(void){hlptim1.Instance = LPTIM1;hlptim1.Init.Clock.Source = LPTIM_CLOCKSOURCE_APBCLOCK_LPOSC;hlptim1.Init.Clock.Prescaler = LPTIM_PRESCALER_DIV1;hlptim1.Init.UltraLowPowerClock.Polarity = LPTIM_CLOCKPOLARITY_RISING;hlptim1.Init.UltraLowPowerClock.SampleTime = LPTIM_CLOCKSAMPLETIME_DIRECTTRANSITION;hlptim1.Init.Trigger.Source = LPTIM_TRIGSOURCE_6;hlptim1.Init.Trigger.ActiveEdge = LPTIM_ACTIVEEDGE_RISING;hlptim1.Init.Trigger.SampleTime = LPTIM_TRIGSAMPLETIME_DIRECTTRANSITION;hlptim1.Init.Outp

Hello all,I am trying to send "Hello World" to my computer through using the guide below but nothing is sending to the port. I cant see anything on Tera Term. (https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step3_Introduction_to_the_UART) (of course I selected STM32F0disco instead because I am not using the board in the example) I have also tried following this tutorial (https://www.youtube.com/watch?v=isOekyygpR8) but I have still seen nothing.I am using a STM32F051 Discovery Board and I am using UART2. PA2 is Tx and PA3 is Rx. When I put an oscilloscope to PA2 I can see quite clearly that the Tx is working and transmitting the data, but it does not look like it is making it to the USB. I don't really care too much about the Rx because i am only trying to send data from the board to the PC. (I am using STM32CubeMX/STM32CubeIDE by the way).I have tried switching cables, switching OS, switching PC's, Switching to UART1 (Which also work fine). I looked at the user manual (UM1525)

Hi,I'm currently working on sending signals through FDCAN or UART of B-G431B-ESC1 while driving a motor.I have written a debug code which sends UART data when a button is pressed.However, the function is called once and never called again, nor the motor won't start."stm32g4xx_mc_it"uint8_t mc_it_debug[64];void EXTI15_10_IRQHandler (void){/* USER CODE BEGIN START_STOP_BTN */  sprintf(mc_it_debug, "StartStop Button Pressed\r\n");  HAL_UART_Transmit_DMA(&huart2, mc_it_debug, sizeof(mc_it_debug));  if (  0U == LL_EXTI_ReadFlag_0_31(LL_EXTI_LINE_10) )  {    /* Nothing to do */  }  else  {    LL_EXTI_ClearFlag_0_31 (LL_EXTI_LINE_10);    ( void )UI_HandleStartStopButton_cb ();  } } in the main.c file, /* Reset of all peripherals, Initializes the Flash interface and the Systick. */HAL_Init();/* USER CODE BEGIN Init *//* USER CODE END Init *//* Configure the system clock */SystemClock_Config();/* USER

Hello,I have second stage bootloader in place and want to change RDP level from it (0 to 1 and roll back when doing firmware upgrade).However, the problem is, once RDP level is changed to 1, bootloader is not able to change it back to 0. I've to change RDP level 0 from ST-link v2 and stm32cube programmer which results in mass erase of the chip (which ends up erasing my second stage bootloader).Is there any way around it ?My actual issue is : I want to disable read from mcu. Either through RDP or any other mechanism (which i'm not aware of at this moment).Device : STM32F767Thanks,Shriram#STM32F767 #RDP

Hi,I m testing SPI TXE flag with the following code:void TestSPI(void){ GPIO_ResetBits(GPIOA, GPIO_Pin_4); SPI_I2S_SendData(SPI3, 0); while (!SPI_I2S_GetFlagStatus(SPI3, SPI_I2S_FLAG_TXE)); SPI_I2S_SendData(SPI3, 0); while (!SPI_I2S_GetFlagStatus(SPI3, SPI_I2S_FLAG_TXE)); GPIO_SetBits(GPIOA, GPIO_Pin_4);}The SPI is set to work with 16 bits.Checking the pins on oscilloscope (see picture attached with yellow for GPIOA 4, blue for SCLK, purple for MOSI), you can see GPIOA pin 4 going high before the second half word is fully sent.Would someone know why the second TXE flag is set while transmitting the second half-word?Thank you.

Hi everyone,I have configured my ADC on STM32F405 in Scan mode to read 5 channels. What I like to do ist to make a single DMA transfer to sample the 5 channels more than one time (e.g. 10x5channels = 50 elemet DMA transfer) To average the data after the transfer.However, I could only run a DMA Transfer with more than 5 elements if I set the ADC to contonious mode. But in Continiues mode, the beginning of the channel order is not aligned to the first element of the DMA buffer (first channel in the sampling order is not necessarily in DMA_Buffer[0]).Is there any solution to this problem, or is the ADC not intended to be used in that way.Best regards 

I want to use a MEMS oscillator driving the XTI pin instead of just a crystal between XTI and XTO.  What are the specifications on the input signal?  AC coupled? Amplitude? Drive impedance? Suggested circuit for a 0V to 3.3V output oscillator?

The output push-pull implies either 0 or 1 - never floating. When do we use the output push-pull with pull-up or pull-down capability? What is the application for the output push-pull with pull-up or pull-down configuration?

Hi. Setup is simple:TIM2 creates the ADC_EXTERNALTRIG_T2_TRGO signal, which starts ADC.

The new mods variant comes without a connector. Do the 14 strips on it’s down side correspond to the CN5 STDC14 connector of st-link mini? Cannot find this in the UM2502. Would like to solder wires to these strips rather than to castellated edge. And what are the 4 strips on the upper side?

Hello. I'm trying to use the st25dv64kc with FTM and energy harvesting and a modified version of the reference ST android application. According to the scope it appears that power is available from the energy harvesting, but there seems to be a pinging sequence occurring from the android side which makes a continued connection to the NFC chip difficult to maintain. Are there any features in the ST android SDK to help with maintaining a connection to the NFC chip or any best practices for maintaining FTM transfers while energy harvesting?Thanks!

Hi!   I have a problem with reading data from M24LR16E. First time i used Android ST25 app.  Then, i tried to write some default data ("This is a text of 64 characters ====...") on NDEF tab, and after the connection lost (Start screen "Please tap an NFC tag..." not changed, the tag not detect). After I tried to read tag on iPhone (NFC Tap application). It detected the tag, but on start application shows the error "Error while processing CCFile".   How i can reset the tag? The ways to restore?   BR!   Anton Ingerman.

Can you please suggest how this issue can be solved.

Hi, can anybody tell me what type of diode I see here?Marking is:VUE XGP 842Must be TVS for low voltage application (24 & 48 VDC)Thanks David

Hello!I'm using ST25R95 with X-CUBE-NFC3 library for an application.I have successfully tried the default PollingTagDetect example. But now, our application requires the usage of interrupt mode for card detection instead of looping NFC_Cycle(); in infinite loop.Application is to just read the UID of the card.@Brian TIDAL @unknown Any help will be appreciated.Regards,Keshav Aggarwal

I have a very simple question concerning the size of the zones and the field of view for (for example) the VL53L8CX sensor. which has a diagonal FoV of 65 degrees. Can anyone provide a simple answer to this question:If the sensor is 1 meter from the target, what size is each (8 x 8) zone at the target?I have tried to follow the app note and calculated 0.37 x 0.37 meter - but I have little faith in my calculation. Thanks

HI, i am studying how to controll vl6180 with a custom board which MCU is STM32L452CCU6. At the beginning , i tried to avoid implementing the api by changing register directly using i2c, however,0x018 is set to 0x2 or 0x0 both did not generate the raw value in 0x064. Therefore, i think there are more config i need to be made before the sensor start reading and an API is required . During searching in the internet, i only found STSW-IMG003 for VL6180X, can i use it for VL6180?Which example could i use just for 1 sensor read range?
