I have insert a images in .png format in one screen. When the simulator run, i'm able to see all the screen but it freeze when it try to load the one with the image. The project is configured in 1bpp and I have edited the image to convert it in black/white without grayscale.

My goal is to have a timer that triggers an interrupt at 1kHz and for that to call a few lines of code that starts a HAL_SPI_TransmitReceive_DMA call (or possibly more than one on different SPI buses). Once the SPI calls are made, it enters a while loop waiting for the SPI communication to finish, then it interprets the data received.I've set up my timer (TIM3) and SPI (SPI1) peripheral using STM32CubeMX. The SPI bus and its DMA channel interrupts have NVIC priorities of 0 while the timer interrupt priority is set to 10. I added this code to the TIM3_IRQHandler function created in the STM32f4xx_it.c file by CubeMX.void TIM3_IRQHandler(void) { /* USER CODE BEGIN TIM3_IRQn 0 */   imu_Tx[0] = FirstData_Reg | SPIReadMask; while (completedSPI1 != 1);   //imu0 start HAL_GPIO_WritePin(ICM0.CS_Port, ICM0.CS_Pin, GPIO_PIN_RESET); completedSPI1 = 0; HAL_SPI_TransmitReceive_DMA(&hspi1, imu_Tx, imu0_reading, 15);   //imu0 end while (completedSPI1 != 1); imu_reading_to_

Hey,I configured the stm32h743 to transfer data with sai2 and read the same data with sai1. Sai2 is in IT mode and works fine (checked it with a logic analyzer).The SAI2 is totally working in IT mode, but when I put it in DMA mode i only receive 0's. Yes, i set the input buffer in D2, its address is 0x30000000 in the SRAM1.the interrupts all work good, no tranfer errors ect.This in my SAI init code:__HAL_SAI_RESET_HANDLE_STATE(&SaiInputHandle);   SaiInputHandle.Instance = SAI1_Block_A; SaiInputHandle.Init.AudioMode = SAI_MODESLAVE_RX; SaiInputHandle.Init.Synchro = SAI_ASYNCHRONOUS; SaiInputHandle.Init.OutputDrive = SAI_OUTPUTDRIVE_DISABLE; SaiInputHandle.Init.NoDivider = SAI_MASTERDIVIDER_DISABLE; SaiInputHandle.Init.FIFOThreshold = SAI_FIFOTHRESHOLD_HF; //SaiInputHandle.Init.AudioFrequency = AUDIO_FREQUENCY; SaiInputHandle.Init.Protocol = SAI_FREE_PROTOCOL; SaiInputHandle.Init.DataSize = SAI_DATASIZE_32; SaiInputHandle.Init.FirstBit = SAI_FIRSTBIT_MSB; SaiInputHand

Posted on August 17, 2017 at 13:48Hello,    I tried the example 'FDCAN_Com_polling' on STM32H743I-EVAL, it worked like it should be.Then I separated the example code into TX part and RX part, made one of my STM32H743I-EVAL board as TX and another as RX, but the RX did not work, it never received anything and the HAL_FDCAN_GetRxFifoFillLevel always get 0.All jumpers and SBs on the EVAL board were removed or connected following the instructions on the EVAL's reference manual, and I checked the waveform on the RX side and it seems correct.The filter setting should be good as well because the TX side can receive its own loop back frame by using the same filter settings.Any hint what went wrong or which part should check next? Thanks in advance.#fdcan #stm32h7

Hello, I'm testing the st-example-image-qt, but when I launch the Qt examples works extremely slow, looks like Qt doesn't use the hardware acceleration.Any clue about it?Best RegardsEduard

I am developing a project with LTDC and StemWin Multi-layer. When I add second layer in LTDC, an option of layer number in GRAPHICS section becomes alerting some strange stuff (if layer_num == 1 - no alert at all). Nevertheless if i generate project - everything seems to work fine. What's the matter?Pic. related:

HelloI'm using TouchGFX 4.10 with a custom board (STM32F767) and I have a problem, where old value/content will be displayed when updating another value on screen.Procedure in which the problem occurs:I have two textareas on screen (e.g. TextA and TextB)The initial values are: TextA: "ABC" / TextB: "DEF"In General: The values will be updated through Model->Presenter->View / Touch is not used(Step1) Updating TextA to "123" and invalidating TextAText on Screen -> TextA: "123" / TextB: "DEF"(Step 2) Updating TextB to "456" and invalidating TextBText on Screen -> TextA: "ABC" / TextB: "456"TextA is wrong!(Step3) Updating TextB to "789" and invalidating TextBText on Screen -> TextA "123" / TextB: "789"TextA and TextB are correct When I repeat Step 2 then I have the wrong values againI don't know where the problem is, but I assume it has something to do with the doublebuffering. When I invalidate both values in every steps, it works correctly. But this can/shoul

Is it possible to animate standard objects (e.g. box, circle, shapes, containers, etc.) with EasingEquations?For example take a circle with a small radius and a thin line and zoom it to a bigger radius and thick line smoothly in 1 second?

For X-NUCLEO-53L0A1, P-NUCLEO-IKA02A1 and X-NUCLEO-IHM03A1, we find libraries, but they don't work. Could you kindly help us? Thank you.

Hey.I just got the STLink V3SET today. I've connected it via usb to my MBP "15 running 10.14.4 (18E226) and the device is not recognized as an USB device. The PWR led is bright green, but COM is not lid I think (I only see a tiny green & red dot).lsbusb reports no new device. Subsequently, I can not use nor upgrade the device via st provided firmware upgrade tool, or use it in stcube programmer. Am I missing something to get this running on macOS ? I used a V2 before which worked just fine.Best,Raphael

Posted on July 05, 2018 at 00:09I am using an X-NUCLEO-IHM03A1 board (powerstep01) to control a stepper motor (17HS24-0644S) speed.When I use the command 'Run (DIR, SPD)' over SPI interface, I observed that the speed in step/s is not exactly the same as requested. (e.g requested 200 step/s, result is 198.4 step/s)I have noticed that by changing slightly the voltage value of the powerstep01 pin VDDIO the speed of the motor changes as well for the same requested value.For example:VDD = 3.3V speed = 198.4 step/s,VDD = 3.4V gives 196 step/sVDD = 3.2V = 201.6 step/sMy application requires to control the speed of several stepper motors precisely and currently this is an issue since the speed varies according to VDD and it is very sensitive.Does anyone knows about this issue, is there a workaround Note: I used the library from https://os.mbed.com/teams/ST/code/IHM03A1_ExampleFor3Motors/with the same initialization parameters.Datasheet: https://www.st.c

I have a STM32F091 Nucleo-64 and have the basic RS232 UART examples (ComPolling and IT) from the Cube working.I need to implement RS485 and was hoping to find a basic example to build upon.I'm currently going through the STM32Cube_FW_F0_V1.9.0 examples and RM0091 Reference Guide and am looking at USART_CR1_WAKE and USART_CR1_MME but a simple example would get me over this initial hurdle.

Hi i am using an cr95hf. After using an idel command and waking up afterwards any command I send after the idle wont work. I don't even get a polling response. Unfortunately I can't find anything in the cr95hf datasheet telling me if i need to reset or anything similar after exiting the idle mode. Also I am using the cr95hf as the plug and it is connected to an atmega 128 and I am communicating via SPI.

Nowadays nobody has single core CPU where project is building, so this option should be enabled by default, or configurable in CubeMX.

In my STM32F72xx/3xx project, I'm not allocating memory dynamically, i.e., I'm using neither malloc nor free. And I'm restricting myself to C, with no C++ parts.Is there a reason I shouldn't set the heap size to zero? Do any of the drivers, HAL or CMSIS, or FatFs, rely on the heap?

I have STM32H743ZI nucleo board. I want to generate code from CubeMx with FreeRTOS.But CMSIS RTOS API is mandotary. I dont want to use CMSIS RTOS API as interface. is there any way to generate code with FreeRTOS without CMSIS RTOS API.

There are multiple alternating functions for one peripherals. Why and what is the difference?

We are running up to 10 temperature sensors which are connected to PC with RS-485 via daisy chain topology. These sensors are placed across the line of sight.Now I am planning to replace RS-485 connection with wireless one while increasing the operating distance up to 2-3 km between the PC and the last sensor in the chain. The PC should collect results in real time every 1-2 seconds (the sensor's result consists of 3 bytes). Measurement results should be available in real time, i.e. received directly.Is it possible to use LoRaWAN for this application? Can you help with a starter kit and sample code, e.g. for longest connection: PC < 2-3km distance > sensor node (the last one in a future chain)?NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hello everyone, I am a beginner on STM32F4. I want to using DMA for receiving data via USART. But it doesnot work, please help me to solve the problem. Here is my code:void USART2_ConfigDMA(void){  DMA_InitTypeDef DMA_InitStructure;  RCC->AHB1ENR = RCC_AHB1ENR_DMA1EN;  DMA_InitStructure.DMA_BufferSize = 10;  DMA_InitStructure.DMA_FIFOMode = DMA_FIFOMode_Disable ;  DMA_InitStructure.DMA_FIFOThreshold = DMA_FIFOThreshold_1QuarterFull ;  DMA_InitStructure.DMA_MemoryBurst = DMA_MemoryBurst_Single ;  DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_Byte;  DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;  DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;  DMA_InitStructure.DMA_PeripheralBaseAddr =(uint32_t) (&(USART2->DR)) ;  DMA_InitStructure.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;  DMA_InitStructure.DMA_PeripheralDataSize = DMA_Peripheral

I want to use DMA on my stm32h7 board, but i can find which channel is used for what protocol ect.

I was wondering if it's possible to use dual-flash memory mode with TouchGFX, and if so is there any documentation available ?

Posted on October 11, 2017 at 17:26Hi,I have a L432KC Nucleo 32 and it never runs as fast as I expect it to.I have configured the clocks in STM32CubeMX as shown in my attached screenshot. I've configured MCO to match the SYSCLK so I can measure it with my oscilloscope.According to STM32CubeMX, the SYSCLK should be 80MHz, but when I measure it with my oscilloscope, it's only 8MHz. If I change some things (e.g. use HSI RC instead of MSI RC) then I can get different speeds, but they never match the value shown in STM32CubeMX.My only guess is that this being a low power version of STM32, does it work in some kind of low power mode with a lower clockspeed by default? If so, how do I get it out of that?Thanks for your help,Colin#nucleo-l432kc #stm32cubemx

Posted on January 31, 2018 at 16:47It looks like the latest STM32CubeH7 is still missing the LL low-layer API? Is it coming and if so, when please?#stm32h7 #ll-drivers
