I learned from the user manual UM2389 that I can get the app from the GooglePlay, but I can't find it.

I'm working on an STM32L431 and I never be call on HAL_CAN_RxFifo0MsgPendingCallback. I have set a break point in this function but the debugger never stop on it.In my program:I have generated the code using CubeMx and I set NVIC on CAN1: Tx, RX0, RX1 and SCEThe cubeMx init is:void MX_CAN1_Init(void) {   hcan1.Instance = CAN1; hcan1.Init.Prescaler = 5; hcan1.Init.Mode = CAN_MODE_NORMAL; hcan1.Init.SyncJumpWidth = CAN_SJW_1TQ; hcan1.Init.TimeSeg1 = CAN_BS1_13TQ; hcan1.Init.TimeSeg2 = CAN_BS2_2TQ; hcan1.Init.TimeTriggeredMode = DISABLE; hcan1.Init.AutoBusOff = ENABLE; hcan1.Init.AutoWakeUp = DISABLE; hcan1.Init.AutoRetransmission = DISABLE; hcan1.Init.ReceiveFifoLocked = DISABLE; hcan1.Init.TransmitFifoPriority = DISABLE; if (HAL_CAN_Init(&hcan1) != HAL_OK) { Error_Handler(); }   }I have disable CAN filtersI already call HAL_CAN_ActivateNotification w/o any error returned:(HAL_CAN_ActivateNotification(&hcan1, CAN_IT_RX_FIFO0_MSG_PENDING)Please see my CAN

Hello.I have a Nucleo board with stm32f302r8. I want to set a state variable for voltage window:state = STATE_OK if higher threshold > current voltage >  lower thresholdstate = STATE_AWD if higher threshold < current voltage or lower threshold > current voltage.I set up a ADC1 with AWD1 and enable interrupt for AWD1 and EOS flags.My handler:void ADC1_IRQHandler(void){   // debug_send(NVIC_GetPendingIRQ(ADC1_IRQn)); //simple uart sender   if (ADC1->ISR & ADC_ISR_AWD1) {      // Exclude the cause of the interrupt      ADC1->ISR |= ADC_ISR_AWD1;      state = STATE_AWD;   } else {      state = STATE_OK;   }   ADC1->ISR |= ADC_ISR_EOS; // Exclude the cause of the interrupt   debug_send(state); // simple uart sender}If current voltage has a permissibl

Hello,I am building the firmware on the M4 core. I have allready modified the 'demo_launcher.py' script to launch my code via the GUI (for demonstration purposes). As the Linux application will be built by somebody else, i only need to do the M4 firmware and use simple script to send and receive messages. I see a lot of info about on the Wiki about the protocol, but my knowledge of Linux is not that great to code this from scratch.Is there a basic example script that i can use and modify for my purpose ? I see a C app here:https://github.com/STMicroelectronics/meta-st-openstlinux/blob/4e36cf0c7c7bdb24700a990f73afcda84cdcf0cf/recipes-samples/ai-nn-application/ai-hand-char-reco-launcher/ai_char_reco_launcher.cthat is used by the 'demo_launcher.py', but i don't currently have a PC set to build this. Thank you!K.

I had my C code running on NUCLEO-F411RE last week. I downloaded it with Keil uVision and STLink driver.  But, I did something when I tried to flash it today with an assembly code instead of the C code.  Now, I cannot flash the device.* A pop up window with the following message."No target connected. "* I get another error message in the Build Output window.Error: Flash Download failed - Target DLL has been cancelledST Link driver is still working.  When I plug in the board, I get STMicroelectroinics STLink Virtual COM Port (COM15) in Windows' Device Manager.  My Keil IDE can detect the board with the correct serial #.  Last week, I had upgraded the firmware on the board through Keil IDE.  I tried to uninstall and install ST Link driver again.  It did not fix the problem.  Could the boot load firmware have been corrupted? Thank you for any help you can offer.Michael

I need to simply add VL53L0x API STSW-IMG005 to my project without any compilation errors. And need to know the necessary functions to get the distance.Regard

Fig. 2 (Memory map) seems to be incorrect as it statesOctoSPI bank2: below 0x60000000FMC bank1: 0x60000000 - 0x6FFFFFFFReserved: 0x70000000 - 0x7FFFFFFFFMC bank3: 0x80000000 - 0x8FFFFFFFOctoSPI bank1: 0x90000000 - 0x9FFFFFFFBut OctoSPI bank2 is certainly at 0x70000000 - 0x7FFFFFFF (verified on hardware). Probably the 'Reserved' and 'OctoSPI bank2' are swapped. The same error appears in the corresponding datasheet for STM32L4R5xx, STM32L4R7xx, STM32L4R9xx.

Hello,I would like to start new design with STM32MP157A in next weeks, but various AppNotes topics, usual for STM32 MCUs was not published, but are mentioned in other AppNotes, exactly:AN5275 - STM32MP1 Series: USB DFU/USART protocols used in bootloadersAN5089 - STM32MP1 Series and STPMIC1 hardware and software integrationAN5256 - STM32MP1 Series discrete power supply hardware integrationBesides this, exact description of default boot pins mapping for respective peripherals and their conditions in embedded bootloader, something equal to"AN2606 - STM32 microcontroller system memory boot mode" just for STM32MP1, etc.In what timeframe will be remaining documentation published ?The only remaining issue is still missing STPMIC1 datasheet.Many thanks.

Hi,I am thinking if it is possible to connect a low power I2C sensor to ST25DC, and use a reader to read out the values through the ST25DV(Powered by the Veh from ST25DC), or do I need extra MCU between the ST25DV and the I2C sensor to done the communication?

Hello All,I received my MP157C-DK2 kit. How do I download the image on it?Thanks,Gil

I have a 32F412GDISCOVERY and I'm interested by the things happening in the demo of the board but I'm not able to find any code. So does anyone have it or have an idea how to get it? I appreciate any help.

I am currently working on the LIS2DE12 accelerometer. I've been reading the datasheet and I was a little confused with the interrupt configuration. The datasheet says the device provides 2 interupt pins (INT1 and INT2). 1. My understanding is that you can use either the INT1 pin or the INT2 pin. Is this correct?What's the reccommended practice?2. In the CTRL_REG6 register, there are two bits I2_IA1 and I2_IA2 for configuring interrupts. Specifically what does "interrupt 1 function", interrupt 2 function" and "activity interrupt" mean?Thanks

I have the following code to perform a serial transaction. The idea is that RX DMA is configured first to catch bytes as soon as they are transmitted in response from the other device. TX works great, but RX does not. Interestingly enough, if I use a different UART with its corresponding DMA, both RX and TX work great (UART5, DMA1 Stream 7, DMA1 Stream 0). This exact code with these settings does not through. Shouldn't it all be exactly the same? This code bails out in the RX timeout.bool UartInit(void) { GPIO_InitTypeDef GPIO_InitStruct;   // Enable clocks __GPIOB_CLK_ENABLE(); __USART1_CLK_ENABLE(); __DMA2_CLK_ENABLE(); // Configure GPIO GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; // TX GPIO_InitStruct.Pin = GPIO_PIN_14; GPIO_InitStruct.Alternate = GPIO_AF4_USART1; HAL_GPIO_Init(GPIOB, &GPIO_InitStruct); // RX GPIO_InitStruct.Pin = GPIO_PIN_15; GPIO_InitStruct.Alternate = GPIO

Hi, I want to create custom SD card for STM32MP157A-DK1board but I did not find any script for it in SDK available. Could you please let me know the procedure to create SD card and how to flash images in it?Thanks,Deshvir Malik

Hi, my custom board has OTG interface. So I reference the dk2 board to configure usbotg_hs as otg mode. But now, the otg interface only recognise on system starting up. It's can not recoginse the hotplug devices. Below is my dts code.

The clock and data lines on SPI seem to go tri-state off when not in use even though the SPI channel is left open. Is this expected behaviour? It causes issues with some connected chips as they see the re-establishment of the driven clock signal as a clock pulseCode is:HAL_SPI_TransmitReceive(&hspi3, mybufft.cTxBuffer, mybuffr.cRxBuffer, 1, 5000);

It seems parallel RGB on the MP151 is supported on the TFBGA361 and 448 package.  Is there any manufacturer of SOM modules (preferably DIMM socket based) with a parallel RGB header ?

Hi, Is it possible to use multiple models in touchgfx. I have designed six screens for my application and all the screens are interacting with a single model. I would like to use separate model for each of the screens. Is it possible to do that. If yes, give me an idea to implement that.

Is there any way to change font of an application? I have a button that change the application style( buttons image ecc) but i need (graphic guy want) also to change the font, size and colout of the text. Is it that possible?

Hello,I used the following "Target Software Startup Script" in the debug configuration in Atollic TrueStudio (this is necessary since we're using a bootloader and our application binary which I would like to debug is not placed at the beginning of the STM32 flash):How to enter this in STM32CubeIDE?I would really need to debug my firmware, but can't figure out how to do the required settings...Any ideas?Kind regards,Markus

We are building a customized board with processor STM32MP157AAD3 and DDR3 of 1GB. I am able to download the source for STM32MP157 from the STM website, and I am not sure with what DDR configuration it has been done.So how to set ddr configuration of 1 GB in the BSP ?Regards, Nitish

Hi guys,I program an application with a STM32LO-LRWAN1 module who does the connection with a sensor by I2C and i would like to integer my application in the "Ping Pong" example for proving to my boss that the connection between two modules is possible. I tried to do that manually but my method look hard and i have problem with multiples define.Do you have any advices for simply put the project who only use the stm32 in the "Ping-Pong" projet on Keil uvision 5. Because i don't think that we have the possibility to modifiy the project with CUBEMx.Is someone has yet done this kind of think or know an other possibility to do that. I appreciate your help.Thanks

I am looking for an accelerometer we can use for motor condition monitoring. Which one would you recommend ?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.

I am using the CCMRAM to store some large array which should be zero-initialized.My definition for the arrays is similar to:__attribute__ ((section (".ccmram"))) uint32_t large_array[4096];Obviously, there is no constructor for these and there should not be a need to store the initial value of this array in flash. However, that is what the linker is doing.The relevant portion of my linker script is as follows:CCMRAM (rwx) : ORIGIN = 0x10000000, LENGTH = 64K   ...   /* uninitialized data in CCMRAM */ .ccmram : { . = ALIGN(4); _sccmram = .; /* create a global symbol at ccmram start */ *(.ccmram) *(.ccmram*) . = ALIGN(4); _eccmram = .; /* create a global symbol at ccmram end */ } >CCMRAM AT >FLASHHow do I get the linker to not store these in flash?I tried removing the ">FLASH" from the previous line, however the binary file produced grew fro ~200kB to 200MB, which is not desired.If I move these arrays to RAM and remove the __attribute__ line, it works as
