Solved

Hello, I have the STM32G474 Discovery Kit and am just attempting to get a blinky LED program to work on it for right now. In the STM32CubeIDE, I imported an example, was able to get it to build correctly (after changing references from caddr_t to void*)  and it seamed to download to the device correctly (verified and everything) after hitting the debugger button. When I pressed run, however, nothing changes on the board. I ended up using the STM32G474E-EVAL example since I was not able to find a blinky LED program for the Discovery Kit. Or any example for the Discovery Kit.  Maybe I am not looking in the right place or perhaps searching for it incorrectly?Are there examples for the G4 discovery kit? And if not, how easy is it to port the examples that I do have to my specific board?Let me know if I can provide any more information that might be helpful. Thanks, Emma 

If I register a callback function for GPIO EXTI and I have EXTI on multiple ports for the same pin (e.g. PA0 and PB0) how does the callback distinguish between the ports when the event triggers?

Hello I have set the timer7 for 1 minute interrupt. It is working at every minute as expected. But the interrupt is also triggered as MCU is reset. I have set global counter for increment in timer7 callback. As soon MCU is reset , Timer7 callback is called and counter is incremented. Please suggest why it is happening.static void MX_TIM7_Init(void){/* USER CODE BEGIN TIM7_Init 0 *//* USER CODE END TIM7_Init 0 */TIM_MasterConfigTypeDef sMasterConfig = {0};/* USER CODE BEGIN TIM7_Init 1 *//* USER CODE END TIM7_Init 1 */htim7.Instance = TIM7;htim7.Init.Prescaler = 65400;htim7.Init.CounterMode = TIM_COUNTERMODE_UP;htim7.Init.Period = 44035;htim7.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_ENABLE;if (HAL_TIM_Base_Init(&htim7) != HAL_OK){Error_Handler();}sMasterConfig.MasterOutputTrigger = TIM_TRGO_UPDATE;sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;if (HAL_TIMEx_MasterConfigSynchronization(&htim7, &sMasterConfig) != HAL_OK){Error_Handler();}}//***********

Hi,a footnote(4) in STM32H7 reference manual RM0468 Table 56 regarding the maximum allowed frequency for ADC says"With a duty cycle close to 50%, meaning that DIV[P/Q/R]x values shall be even".Does this recommendation apply to the actual DIVXx register bits value or the resulting actual divisor /(DIVXx + 1) ?Or, in other words, is DIVR2[6:0]=0000010 (ie. /3) be regarded even (0000010) or odd (/3) and thus not well suited in this context? I assume the latter?Thanks for clarificationKolja

Hi, I am trying to synchronize a SPI Block data transfer between two MCU's (Ti MSP430 Master, STM32G0 Slave). The idea is to use the DMA to transfer the data to memory and use the DMAMUX to Sync with a timer. For demonstration, the data is transmitted to USART.Here is my result:The red cycle mark the sync point generated by the timer interrupt of LPTIM1.For testing, a defined pattern with 6Byte is transmitted via the SPI. And you can see that the data is not in sync with the block transmission. Has anyone an idea how to solve this?SPI1 is configured to receive the data in Slave mode and use DMA.DMA Channel 3 is configured to transmit data from SPI1Rx to memoryDMAMUX Channel 2 is configured to SPI1Rx synced by LPTIM1 

There is mistake in either the documentation or the source code, which one is correct please advise. __weak uint16_t PWMC_SetPhaseVoltage(PWMC_Handle_t *pHandle, alphabeta_t Valfa_beta) { wUAlpha = Valfa_beta.alpha * (int32_t)pHandle->hT_Sqrt3;  wUBeta = -(Valfa_beta.beta * ((int32_t)pHandle->PWMperiod)) * 2; }   But if you compare with the documentation In the alpha code the PWM period (T) is missing. In the beta code additional 2 is found. Why there is a difference? Please help.

LPUART1_TX - PA2LPUART1_RX - PA3I'm having trouble testing because I'm getting frame errors by UART1.My PCB didn't design any circuit for PA2 and PA3 because the IC that connects to the MCU's UART pin uses 3.3V TTL communication.However, using the HAL code, the HAL_UART_Init function automatically enters the HAL_UART_ErrorCallback function even if the IC is not connected.Interrupt and DMA methods are the same.I am not considering the Polling method because of the possibility of missing bits.I also use UART2, but UART2 is not a problem.Only UART1 is the problem.My board might be the problem, so I tested it on the NUCLEO-L031K6 board, but the result is the same.Is there any way to solve this problem?I am attaching the code, which is very simple, but outputs an error.In fact, there are only three functions in the code that need to be executed to see the same problem.MX_LPUART1_UART_InitHAL_UART_Receive_DMA or HAL_UART_Receive_ITHAL_UART_ErrorCallbackHopefully we can resolve this issue.

Hello, hope this message finds you well.So, I'm on a project that requires multiple timers to generate 7 variable pulse waveforms in master/slave mode and I'm hoping to get parallel synchronization at startup, I'm using timer 1 as master, and timer 2 as a slave.I have done things as per Reference Manual and ST knowledge base videos and articles, so can't see any extra detail that might cause this issue described below.The device is STM32F103C8T6, and I am using HAL libraries.The issue:Tim2 does not align with Tim1, seems to me their alignment is code dependent, so sometimes they align perfectly, and when you change the code even in non-timer-related sections they get out of alignment.more useful info for you:TIMER 1 (Master) settings:CH1,2,3 are "PWM Generation" and CH4 is either "PWM Generation NO Output" or "Output Compare NO output" have tried both, does not make a difference.No Prescaler is used so Clock is 72Mhz, only using ARR for Frequency adjustments.  RCR => 50. T

Hello I am using STM32F0 Series MCU. I am saving some data every 10 minutes on external Adesto flash. I am able read data from ext flash and display on console using printf command. Now I want to save the data on external file rather than just display only. please suggest a way so I can save data  in .txt file

I am trying to setup stm32h745 Nucleo board. Is the yellow triangle issue of concern or not ?I am using internal oscillator. 

Hello everyone,I try to check the LOOPBACK mode on the NUCLEO-L432KC board, but doesn't work. The CAN frame transmitted is correct, but I don't receive anything. I'm checking the TX frame output correctly with an oscilloscope.The code is very simple, but I suppose that has a bug (attached), ...could anyone help me? 

I have been trying to install STM32CubeMX (SetupSTM32CubeMX-6.9.1-Win.exe) for a *while* and yes I right-clicked and chose "Run as Administrator". It always fails during step 8/9 with the same message that "'C:\Program' is not recognized as an internal or external command, operable program or batch file."  which is something anyone who has written many scripts or installers has overcome a couple times before not making that mistake again (or at least very often). If I choose "No" here, I can then get to the error details window:The full text from this window is :com.izforge.izpack.api.exception.IzPackException: An error occuredin java.lang.Thread.run() at Thread.java:833in com.izforge.izpack.installer.unpacker.UnpackerBase.run() at UnpackerBase.java:241in com.izforge.izpack.installer.unpacker.UnpackerBase.unpack() at UnpackerBase.java:319Caused by: com.izforge.izpack.api.exception.InstallerException: File execution failedin com.izforge.izpack.installer.unpacker.UnpackerBase.u

Hello,I am running on the STM32H725AGI6 on a custom board. I am trying to use the TouchGFX GUI with the LTDC interface (RGB565). I am trying to run a firmware that I had previously working on another of the H7 series (STM32H7B3IIT6). The hardware is identical in all aspects, except for changing to the AGI6 MCU.  I am running the debugger to try to isolate the issue and I observed that the model::tick() function was only called once. Additionally, the TouchGFXHAL::taskEntry() is also only called once. On the IIT6, this problem was not present.  I have tried the following so far:- Increased the heap size (it says I still have plenty of heap available)- Increasing priority of the TouchGFX- Removing the BLE_Task I have to prevent multiple tasks from causing issues None of these solutions have worked yet. Does anyone know what would cause a task to only be called once? Edit:I also enabled vApplicationMallocFailedHook(void) to see if it entered this functio

Hi,someone can explain me how to calculate the "dummy cycles" number reading an external flash qspi such as the Winbond W25Q64JV ?I have to read in qspi mode with the Fast Read Quad I/O (EBh) command in SDR mode. The flash memory datasheet asks for 4 dummy cycles between addressing and data available.In effect, if I set 4 dummy cycles, the first data byte is lost. On the contrary, if I set 6 dummy cycles, the read operation success.I think this depend to the Pre-drive time, but how can I calculate the effective dummy cycles to apply, to be sure that all the reading will be done correctly ?Thank you.

I am using multiple VL53L5CX sensors to measure distances around a robot using the 4x4 resolution, target order closest and ranging in countinuous mode. When I'm measuring a distance close to the sensor ~500mm and then the object is suddenly removed so the distance becomes very far +3500mm, I get strange readings. The distance measured just freezes at the last measured distance, for example ~500mm and I get no weird target status exept for maybe a 10 in a few zones. Is there a way to detect this 'out of bounds' so I know to ignore the last reading and just set my measured distance to a certain out of bounds value?

I am using the STM32G474 and have the following situation:I have configured a Timer to run continuously at 25 kHzThe Timer triggers the ADC to start a sequence of 6 conversions (i.e. 6 ADC channels)Upon completion of each ADC conversion, DMA transfers the sample to memory (repeat for the entire sequence of conversions)Repeat steps 2-3 until the buffer is full (ADC DMA half-conversion/full event & double buffering is used)This buffer now contains interleaved samples from the ADCSome magic de-interleaving needs to happenA de-interleaved buffer of ADC samples (i.e. for a single ADC channel) is passed to the FMAC (filtering) peripheral using DMAThe output of the FMAC peripheral is transferred to memory via DMARepeat steps 7-8 until the sample buffers of all 6 ADC channels have been filtered via FMACIdeally I want to keep the CPU asleep for this whole process; the CPU should only wake up at ~100 Hz to process the filtered data (i.e. FMAC output stored in memory) and perform other functi

With SYSCLK set to 400MHz in MX Clock Configuration there is no problem, but any setting above ~420 up to the maximum of 480Mhz causes the system to 'crash' during initialisation in HAL_RCC_ClockConfig(..). More specifically when or after RCC->CFGR is updated with the clock source. Cortex_M7 is not currently configured. Has anyone experienced something similar?

Hello, I am currently using the STM32F407IE (Board A) and want to use another STM32 (Board B) with it, but I want to be able to program board A via board B using a SPI interface as I can use this as a general comms interface as well. I know you can program through the SPI interface from AN4286 but it doesn't specify if any specific port needs to be used. my question is can I use any SPI port on the STM32F407IE to program through the bootloader? or does it have to be  a specific SPI port? assuming I have access to the BOOT0 pin and the NRST pin from board B. Thank you in advance. 

Hello,I am currently working with the ST25RU3993 SDK in C language to develop a program that retrieves RSSI linear in I and Q mode. However, I've encountered an issue where the RSSI linear values remain constant every time I run the code. I could use some assistance in resolving this problem. Would you be able to provide some guidance? Thank you.This is my code:STUHFL_T_Gen2_QueryMeasureRssi queryMeasureRssi[1] = { STUHFL_O_GEN2_QUERY_MEASURE_RSSI_INIT() };setupGen2Config(false, true, STUHFL_D_ANTENNA_1);Gen2_Inventory(&invOption, &invData);demo_gen2Select(invData.tagList[0].epc.data, invData.tagList[0].epc.length);Gen2_QueryMeasureRssi(&queryMeasureRssi);int RSSIlinI = queryMeasureRssi->rssiLinI[0];int freq = queryMeasureRssi->frequency;int RSSIlinQ = queryMeasureRssi->rssiLinQ[0];printf("freq= %d", freq);printf("RSSI_I= %d", RSSIlinI);printf("- RSSI_Q= %d\n", RSSIlinQ);

The SPI2_MISO pin (PI2) at the arduino connector of the STM32H745XI board was accidentally connected to the MOSI of another SPI device giving around 5V and now the board red LED (LD3) keeps being on...According to the user manual, this means STLK Over Current. In the FAIL.TXT file: The interface firmware FAILED to reset/halt the target MCUIs there a way to fix that? I am afraid that the Core is permanently damaged??

Hi,I am on a steep learning curve here. There are huge gaps in my understanding of the field, so any help will be most appreciated. Basically I am trying to connect to AIS2ih accelerometer (on Steval-mki218v1) with my Nucleo board, and try to communicate with it. So far I do fail miserably, and have no idea what am I missing. Basically I am getting the i2c slave address of the AIS2ih, and some register addresses (CTRL1, and CTRL6), than I try to write to them to start the accelerometer, after that I am trying to read Who_am_I register just to get some feedback that the concept is working, but it is not.Here is my code (not really mine, but an adaptation really), and photo of my wiring.
