I connected JP1 part to 3.3V pin, Gnd to Gnd pin, Mosı, Mıso, CS and Clk pin to CS,Mosı,mıso, sck pins of the microcontroller in CN7 with the help of jumpers.Bu't I dont know where my DCMI connection(CN4) and shutter, flash connection get interacted with nucle 144 board via using only jumpers. My aim is to get live view from the camera to control my output with buzzer or something else. All connecitons I checked from the internet are done with a display camare done with FFC Cable but ı am trying to connect the module to microcontroller via only using jumper cablesthanks

My test program for my STM32F746VET6 is extremely simple. Other than MX configuring the clock and GPIO, I only have a while loop that flashes some LEDS and then divides by zero. while (1) { /* USER CODE END WHILE */ uint32_t bobbycounter = 0; uint32_t bobbycounter2 = 0; while(1) { if(bobbycounter++ & 0x100000) { STATUS_LED_1_GPIO_Port->ODR &= ~STATUS_LED_1_Pin; STATUS_LED_2_GPIO_Port->ODR |= STATUS_LED_2_Pin; } else { STATUS_LED_1_GPIO_Port->ODR |= STATUS_LED_1_Pin; STATUS_LED_2_GPIO_Port->ODR &= ~STATUS_LED_2_Pin; }   if(bobbycounter > 0x800000) { bobbycounter = bobbycounter / bobbycounter2; } }When I debug in MX, I get the expected behavior where I enter the HardFault_Handler and then flash the LEDS at a faster rate forever:void HardFault_Handler(void) { /* USER CODE BEGIN HardFault_IRQn 0 */   /* USER CODE END HardFault_IRQn 0 */ uint32_t bobbycounter_hf = 0; while (1) { /* USER CODE BEGIN W1_HardFault_IRQn 0 */ if(bobby

My biggest issue currently is on my external app which is connecting to the WB that it cannot get the descriptor.As I debug using BLE using LightBlue there is no descriptor in my characteristic. As I notice recently by reading again the manual there is a command aci_gatt_add_char_desc() which in my opinion add the missing descriptor. By generating the default project with cubeMX, this function is never called. As there are no comments in the code, neither any documentation about this routine, this makes it hard to implement correctly. This would really helpful if the documentation could be extended (@Remy ISSALYS​ ). Thanks in advance!

HiI try to read the WHO_AM_I register using SPI but I get 0xB3 instead of 0xB1. Is this correct?Regards

I am using a STM32H723zg board for a project and I must read analog signals so I am using one 16-bit ADC. Based on the datasheet of this microcontroller serie, the maximum ADC clock frequency is 50 MHz for BOOST = 11.However when I am configuring the ADC clock frequency with the STM32CubeMX, the ADC clock is automatically set with 96 MHz with no error. I would like to know if this ADC clock frequency configuration (96 MHz) affects negatively to the performance of the ADC (noise or erros in measurements) and if this ADC clock frequency is actually used by the microcontroller or if the microcontroller automatically uses another frequency that does not exceed 50 MHz.I didn't find anything very useful in the documentation related to this question.

I am using a Nx_Webserver application example from STM32H735G-DK modified for STM32H743i-Eval. I have moved the Rx, Tx, NetXPool references to RAM_D2 and I find that I get an error when the linker runs if the RxDecripSection and TxDecripSection name matches that which is in main. If the names are different it links fine and the map shows the sections mentioned in 0x240xxxxx. Not what I want.the likker script looks like this:/* Entry Point */ ENTRY(Reset_Handler)   /* Highest address of the user mode stack */ _estack = ORIGIN(RAM_D1) + LENGTH(RAM_D1); /* end of RAM */ /* Generate a link error if heap and stack don't fit into RAM */ _Min_Heap_Size = 0x200; /* required amount of heap */ _Min_Stack_Size = 0x400; /* required amount of stack */   /* Specify the memory areas */ MEMORY { FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 2048K DTCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K RAM_D1 (xrw) : ORIGIN = 0x24000000, LENGTH = 512K RAM_D2 (xrw) : ORIGIN = 0x30000000, LENGTH =

We've been building a PCB with four STM32F091s on each PCB and we've built about 50 units by now (over about 3 years). I have now seen three PCBs where the ADC readings are 'bad' on two of the four micros. By 'bad' I mean conversion values are 30% ish low. With the design having been stable for quite a while, the chances of uncovering a new bug seem slim, but chip damage seems even more unlikely. The fault also 'went away' on one of the PCBs, so more evidence that it's not damage.The ADC reference is VDD 3.3V on all the chips, and they all run the same code.Anyone got any thoughts?

Hi!Our incoming inspection unit failed to find any information on LSM6DSLTR device marking. We got parts with 2 lines on it.SF2D code106 Could you please confirm it is a LSM6DSLTR device? Is there date code on it?

I using STM32CubeIDE and STM32L03.I don't understand how to make a simple sample of a ADC channel (in blocking mode). I had config the Cube to generate a ADC_Init() that contains my 6 Analog In channels. I want to have a function that goes like this: uint16_t AD_Read(unit32_t channel) { ... }I make a ADC_Start and then HAL_Polling() and then get the ADC value. Doing that for 20 samples. But where do I set what ADC channel I want to read? Is it the rank member I set before I calling HAL_ADC_Start() or what? The first channel in ADC_Init has this "rank" member set.The config I tried to keep as simple as I could. No group scanning or continuous scanning and no interrupt.The ADC_Inithadc.Instance = ADC1; hadc.Init.OversamplingMode = DISABLE; hadc.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV4; hadc.Init.Resolution = ADC_RESOLUTION_10B; hadc.Init.SamplingTime = ADC_SAMPLETIME_19CYCLES_5; hadc.Init.ScanConvMode = ADC_SCAN_DIRECTION_FORWARD; hadc.Init.DataAlign = AD

I'm working on a project where I need to send and receive http requests/response over tcp/ip, I can get only 3 ethernet modules from my local store - ENC28J60/W5500/W5100. After doing some research I found out basically all 3 of them can work for me, but at the same time none of them have proper HAL library I can use to easily implement them in my project.So I need an advise on whichever one of those 3 I should use, which would be simpler to add and work on?If anyone already used them in HAL previously and already has a working library I'd appreciate it, otherwise I'll need to port them from Arduino libraries.

I'm using the latest 6.7.0 version of STM32CubeMX for generating the code. I'm selecting just the serial wire and the a different timer for tick generation and nothing else. The code generation is completed without any errors. But when I try to compile I get about a zillion errors regarding FreeRTOS. Did a lot of search and tried different solutions provided. Like this one here. But nothing worked so far. :weary_face: Has anybody tried similar config ? Thanks in advance for your help :smiling_face_with_smiling_eyes: Here is the starting and ending lines of the build output. Had to snip off a bit as the post was getting too long. :grinning_face_with_sweat: Build started: Project: Test *** Using Compiler 'V6.19', folder: 'C:\Keil_v5\ARM\ARMCLANG\Bin' Build target 'Test' compiling stm32g0xx_ll_rcc.c... compiling stm32g0xx_hal_timebase_tim.c... compiling app_freertos.c... compiling main.c... assembling startup_stm32g030xx.s... compiling stm32g0xx_it.c... compiling stm32g0xx_hal_msp.c... co

I have the latest CubeIDE and have selected SDIO 1-wire and FatFS. As stated numerous times in the past it doesn't work. The funny thing is, years later and it still doesn't work...Can someone (preferably an ST employee as they get paid) post a written tutorial?

is there any STM32 variant which has on chip IoT/ WiFi connectivity module. So that it can be configured and used just like USART or timers.Regards

HAL_I2C_IsDeviceReady is good option to check sensor presence but while i2c sensor working incase of error occurrence will error interrupt will be triggered ?

I have a large firmware that the MCU must execute. It will not fit into SRAM1-4, so I am trying to move the entire code (or a portion of it) to DDR RAM. I have no problems reading and writing DDR memory from the MCU, as long as it's just data, but for some reason when the PC jumps to an address in DDR, execution halts (or we get a HardFault, depending on if a debugger is attached to the MCU). If I move this section to SRAM, then everything works fine (except that my MCU firmware is limited to 384kB).I have set the linker so that the MCU code's entry point and Reset_Handler is in SRAM, and one particular linker section is in DDR RAM (0xC5000000 for example). I've verified the M4's elf file contains the proper sections. When I run the program, the A7 MPU properly loads the raw data of the M4's code into 0xC5000000, and I can confirm with a debugger that these addresses contain valid Cortex-M4 instructions.After that, the A7 releases the MCU HOLD on the co-processor. With a debugger attac

hi, i'm trying to make USB_FS work on my custom board. my desired configuration is peripheral (otg can be ok, i have jumper on id: PA_10)i already have 2 USB HS so i can use only USB_FS mapped on PA_11 and PA_12 as OTG. i follow the st wiki at the point 3.3.1 witn dr_mode = "peripheral";my result is: i can see 49000000.usb-otg under /sys/class/udc/i can create one gadget device in /sys/kernel/config/usb_gadget/g1 (i created serial over usb) as i assign 49000000.usb-otg > /sys/kernel/config/usb_gadget/g1/UDC, usb does not turn on, i always have 0V on PA_11 and PA_12 if i follow the st wiki at the point 3.3.2 witn dr_mode = "peripheral";all works great and i can create my usb gadget more info: my micro is STM32MP157F i'm using linux 5.10.10i have NO hardware pull_up or pull_down on any line i have VDD3V3_USBFS shorted with VDD3V3_USBHS (both connected to 3.3v)my otg port is B_TYPE and i have one jumper to select OTG mode (i need only peripheral) can anyone help me?

Hello everyone, I have been working with stm32h747xih6 MCU for a while now. I'm trying to establish ethernet communication with the MCU. if (netif_is_link_up(&gnetif)) { /* When the netif is fully configured this function must be called */ netif_set_up(&gnetif); } else { /* When the netif link is down this function must be called */ netif_set_down(&gnetif); }My code always goes to the else condition in the above snippet of the code.I have attached my .IOC file below for reference.At times when i do arp -a from command terminal my device IP comes on the command prompt but when I try to ping the connection is lost.Kindly help me out with this issue

STM32F207IGH used in the existing product. We see that we need more Flash & SRAM to include more software features. STM32F427II is having double the size of both Flash & SRAM. What is the process to migrate software to STM32F427II? Micrium RTOS used in the existing product. Is there any easy way to migrate software code?

I am looking for an example for USB audio device class UAC1 for NUCLEO-H723ZG.The aim is to stream audio data from STM32 onto an android device (and there to a spectrum app). Many thanks to any hints.
