I have tried several times to find the datasheet of the M4 coprocessor inside the MP15xx but actually I was not able to find it. Can someone please point me to the download location?

Hi ST Community,There is no software provided for the SPC5 47s 64E3 like low level drivers for the Controller.

Hello techies,I am using STM32H563MI for one of the embedded application, I have to start the design hence looking for readily available OrCAD library.Appreciate if anyone has the library for schematic and Allegro layout footprint.  This helps my team not to re-create same symbols/footprint. ThanksVignesh 

I have configured a STM32 project in the ioc interface to use SPI2 - I can see it having the green check mark in the ioc interface. However when I generate code I don't see any spi driver header, and when compiling I get a:error: unknown type name 'SPI_HandleTypeDef'; did you mean 'TIM_HandleTypeDef'? I am using the STM32CubeIDE version 1.16.0 on mac.

I am attempting to get the GHS compilier to build with SPC58NG dev kit and have switched the Build settings to below  I have updated the project to include the path and commented out the error statementifeq ($(GHS_PATH),)export PATH := C:\ghs\comp_202114\$(PATH_SEPARATOR)${PATH} # $(error Please specify a valid path into GHS_PATH for ccppc (GHS) compiler)endifand it will compile but then include some strange error that doesn't really help. Is there any setting I need to fix it looks to be something in the linking process.

I used CubeMX to generate CMake project for STM32H750XBH6.Then I have to modify STM32H750XBHx_FLASH.ld because DMA1 can't access the DTCMRAM./* Specify the memory areas */ MEMORY { DTCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K RAM_D1 (xrw) : ORIGIN = 0x24000000, LENGTH = 512K RAM_D2 (xrw) : ORIGIN = 0x30000000, LENGTH = 288K RAM_D3 (xrw) : ORIGIN = 0x38000000, LENGTH = 64K ITCMRAM (xrw) : ORIGIN = 0x00000000, LENGTH = 64K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 128K } /* Uninitialized data section */ . = ALIGN(4); .bss : { /* This is used by the startup in order to initialize the .bss secion */ _sbss = .; /* define a global symbol at bss start */ __bss_start__ = _sbss; *(.bss) *(.bss*) *(COMMON) . = ALIGN(4); _ebss = .; /* define a global symbol at bss end */ __bss_end__ = _ebss; } >DTCMRAM But everytime I use CubeMX regenerate the project, STM32H750XBHx_FLASH.ld will be recovered.

Is the VL53L7CH software (STSW-IMG043_ULD) a superset of the VL53L7CX (STSW-IMG036) software? That is, can I use the VL53L7CH software with both devices?Best,Anton

Hello everybody,This is my first post hope i wll get the answer.I am building a spectrometer for which i am using a stm32f401re board and i need to sample the data coming from a sensor at 250kHz which nearly gives a data rate of nearly 4Mbps so do i need to use 4Mbps baud rate to read that and if so how to achieve such higher baud rates.Thank you.

I am using STEVAL-CTM009V1 (Eval Board) and STEVAL-TTM002V1 (Control Board) for Motor Control, by software side (SPC5 and MC Monitor Live), it is controllable. I want to interface throttle with it but i am unable to find throttle signal in eval board, have gone through the documentations but no use, Please Suggest !

Hi all,I am facing issue with Open Load detection in PLAY mode and it is working fine in MUTE mode.I have flashed and tested  the example base code from STM(Autodevkit), Open Load Detection is not working in PLAY mode in this code(Placed the example code snippet below). In MUTE mode, If either or both speakers are disconnected the signal is updating with value FAULT_OPEN_LOAD_MUTE as shown below-In PLAY mode, If speakers connected or disconnected also both both conditions the value of signal is updated with "NO_FAULT_PLAY" as shown below-The structure member "OPENLOAD_PLAY" of structure "FDA_Errors_t" which is getting value from the registers is itself not updating during PLAY mode.Can anyone help me to come out of this issue. Thanks,Aishwarya UM

I am using TouchGFX 4.24.0(The newest version). It does not seem to generate the newest version of code for STM IDE to use. I think this causing problems when I need to make changes between the script and the gui. Is there a way to change what version of code is generated?  I have no examples to show, other than it prompts me to "Migrate" to a newer version when I go to the IDE. When I start to make changes to the original gui it obliterates my code, Wigits go missing, screen flickers. I am using the board STM32H735G-DK.

Hi,On an Stm32f4 based board, we have the external crystal (8MHZ) mounted. The Firmware however uses HSI clock. Does the HSI drift have an impact on CAN communication with another device over a long period of time(say weeks)? Is it recommended to use HSE instead? Thank you in advance for your inputs.

Hi is the stack stm32wb5x_BLE_Stack_full_fw.bin and the one which we generating through cubemx(BLE Wireless stack Full) are same?

Hello!I'm using a 320x240 TFT display with ST7789V driver and SPI interface by X-CUBE-DISPLAY. Pixel transfer works correctly when I use the BSP_LCD_WriteData function. I can also display images and animation using the TouchGFX framework.However, when I use the BSP_LCD_WriteDataDMA function to perform the same process but with DMA, I encounter an anomalous behavior that I cannot explain.The code transfers the data successfully and the display show the image during the first execution. Then, on the second execution, the display suddenly turns off, blacking out all pixels, as soon as the BSP_LCD_SetDisplayWindow function is called. Despite this, neither the driver nor the DMA reports any errors. uint32_t Display_TransferData(uint8_t useDMA, uint8_t * data, uint32_t size) { uint8_t * ptr = data; uint32_t i = 0; while(i < size) { uint32_t n_byte = 65534; if(size < i+n_byte) n_byte = size - i; uint32_t ret; if(useDMA) { ret = BSP_LCD_WriteDataDMA(0, ptr

Hi, I am experiencing a problem on the STM32F411RET6 and STM32F411RCT6 MCUs. When programming these devices I am getting a repeated "Target is not responding, retrying..." message until the debugging session shuts down and exits. I have managed to narrow it down to the something related to the Main PLL. The MCU works if the 16MHz HSI RC clock or the 8 MHz HSE clock is selected as the System Clock Mux source, but fails with the "Target is not responding, retrying..." message if the PLLCLK is selected irrespective of whether the HSI or HSE is selected as the PLL Source.In a desperate effort I've also replaced the STM32F411 with a STM32L433RCT6 which pins are almost an exact match to that of the STM32F411. Using this MCU the PLL works as expected and I can use either the HSI or HSE as the PLL Source.I've attached the non-working STM32CubeIDE STM32F411 project which toggles pin PC8. Any assistance will be greatly appreciated. ThanksRenier

Hello everyone,I have recently been trying to get the CAN1 bus working on the STM32F427. So far, however, it has not worked in either loopback or normal mode. For the normal mode I had a CANCaseXL Analyzer available. The problem, however, is that not even the loopback works. I have attached the main.c file and the ioc project file.When I call HAL_CAN_AddTxMessage(), I get HAL_OK back, so that seems to work. However, I have set a breakpoint in the CAN interrupt handler (HAL_CAN_IRQHandler() in file stm32f4xx_hal_can.c) and there I see that the TERR0 bit gets set. Accordingly, the transmission process has failed. I have already tried many other possibilities, which unfortunately did not work either.Maybe someone has an idea. Many thanks in advance!Louis

Hi guys,I've trying to use the S2-LP DK v1.3.5 with the STM32L053R8 and STEVAL-FKI868V2.However, I can not open "COMx (ST DK)". The S2-LP DK shows  "Wrong firmware detected".I've flashed and uploaded the "S2LP_CLI_NUCLEO_L0.bin" but still shows same "wrong firmware detected" message.I've also downloaded the same firmware by using the IAR EW, but still have same message by S2-LP DK.Would please resolve this issue.I wonder the my board or the ST-Link driver for the windows 11 have some issues.Regards,- ChutaTheCat2024 

Hello! I'm new to STM32 hardware, and I'm having some difficulties getting it running on my Black Pill board with an STM32F411CEU6. It has both Read and Write Protection enabled, and I am trying to disable them using STM32CubeProgrammer through an STLINK V2. However, upon trying change option bytes, it gives me a weird error.For attempting to change read protection from value 0xFF to 0xAA it gives me this:16:24:25:038 : Error: Expected value for Option Byte "RDP": 0xAA, found: 0xFF 16:24:25:044 : Error: Option Byte Programming failed Or modified by application after OB_LAUNCH And similar story for trying to change the write protection values from true to false for all flash sectors: 16:26:41:386 : Error: Expected value for Option Byte "WRP0": 0x0, found: 0x1 16:26:41:391 : Error: Expected value for Option Byte "WRP1": 0x0, found: 0x1 16:26:41:395 : Error: Expected value for Option Byte "WRP2": 0x0, found: 0x1 16:26:41:399 : Error: Expected value for Option Byte "WRP3": 0x0, fou

Hello my friends,I am trying to setup an I2C slave that is being addressed with a read-request and then answers a fixed number of bytes. I was trying to find out what the XferOptions do, but after I could not find out I went through the HAL-driver code myself and found no location where they are actually being used. The basic procedure is, that interrupts are being generated by the hardware, set some flags, and in the TX-Slave part of the code, nowhere the XferOptions are used (am I right?). So I dont know what to do with them, just write anything in? Is this a "Bug" in that sense that the lib asks you for a parameter that is never being used? void HAL_I2C_AddrCallback(I2C_HandleTypeDef *hi2c, uint8_t TransferDirection, uint16_t AddrMatchCode){ if (TransferDirection == I2C_DIRECTION_TRANSMIT) // if the master wants to transmit the data { //HAL_I2C_Slave_Seq_Receive_IT(hi2c, &dummy_in, 1, I2C_FIRST_FRAME); RINGBUFFER_reset(); } else{ RINGBUFFER_dequeue(&data);

I am controlling a VN9D5D20FN high side driver with the SPI2 interface on an STM32F373.  I can communicate with the high side driver, and sometimes briefly get an output to turn on using SPI control.  However, frequently the high side driver sets the SPI Error bit in the global status byte, mask 0x20.I cannot determine why the high side driver is reporting a SPI error, and the datasheet is not clear on what causes that bit to be set (or at least I haven't been able to find it).  The datasheet is here: https://www.st.com/resource/en/datasheet/vn9d5d20fn.pdfOn page 23, it states:"The SPIE is a logical OR combination of errors related to a wrong SPI communication (SCKcount and SDI stuck at errors).The SPIE bit is automatically set when SDI is stuck at High or Low.The SPIE is automatically cleared by a valid SPI communication."So, it appears SPIE gets set if SDI is stuck High or Low, or there are not enough SCK counts when receiving (24 bits per SPI transaction).  From

Hello, I am trying to read battery voltage within a task called by sequencer on STM32WB55CEU.I am following this post: https://community.st.com/t5/stm32-mcus/how-to-use-the-stm32-adc-s-internal-reference-voltage/ta-p/621425I verified that I can measure both VREFint and Channel 10 separately in Single Mode, however combining 2 measurements in Scan mode does not work. I am not sure whats causing this, considering I am doing everything as recommended in the provided post. It may not be related to BLE. I must be missing something obvious.In the following code, the call to  /* * Rank 2: measurement channel */ stat = HAL_ADC_PollForConversion(&hadc1, 0xffff); uint32_t measurement_raw = HAL_ADC_GetValue(&hadc1); takes about 10 seconds and measurement_raw becomes same value as vrefint_raw. The Vrefint conversion seems ok.This is the whole code: void ADC_BattMonitor_Init(void) { HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED); __NOP(); }

Hi,I have a custom master PCB connected to a few slave custom PCBs via serial. In some systems they are connected via I2C and in other systems they are connected via RS232.They all run STM32 micros.I am looking for two out-of-the-box protocols with source code available, one for the I2C and one for the RS232. They need to be very simple because only very little and simple data is exchanged (enable motor, change state machine state, turn LED on/off, etc) and none of it is time critical either.Which protocol would you suggest and where can I find the source code?Is there any such or similar solution provided by ST?Thank you :) 

     Hallo everyone,Since some time I struggle to get DMA access working on a STM32H723. I was pointed out this MCU is a complicated beast, but I would at least expect sensible, coherent documentation for it.When I look at page 683, I see:on next page: and on page 691:At the bottom of page 672 I read:These pieces of information confuse me: the register name in the headers are different from the ones in the Register Map, and it looks to me there is no register for 'DMAMUX2CRxC'.Further, when I run the debugger on an application that intends to use DMA on SPI3_Tx, I failed to read the registers mentioned above in the column "Live Expressions", because I didn't know the correct names. Although the column 'SFRs' show:combinations like: DMAMUX1_C2CR, DMAMUX_C2CR, DMAMUX1.DMAMUX_C2CR, etc. did not result in showing values. I find it quite an omission in the documentation that an user gets bits and pieces information andmust guess how to put it together to one coheren
