Usually the ST has a lot of documentation of their products. I also found few people also write in Internet that it is impossible to find any information about this ST productIf somebody can share more information about this IC

We have facing issue on microntroller we have recieve we have serial product and curretly we are using STM32F072VBT6 controller but we have order new lot and we are recieve STM32F072VBT6 2 and both are behaviour diffrent so what is major diffrence between them ? please suggest me.

My setup is:STM32H753 eval boardSTM32CubeIDE 1.10.1code generated with arm-none-eabi-gcc (no stdlib, no semiihosting, no ITM)The code is located in AXI-SRAM memory.I can execute the code and break wherever I want. However when I break I cannot step into the code (or continue execution). When i do so (whether it is Step into or step over, assembly mode or normal mode) the code remains at the same instruction (everything happens as if the instruction is not executed). The disassembly is correct. There is no "bkpt" or other particular instruction.I obviously tried to set the bkpt at different locations.i also tried to set it up after the code is loaded to RAM. I also set the bkpt as "hardware" instead of "regular"When the code is executed from somewhere else (like ITCM) it works just fine.Any idea ?

Is stated on STM32MP157 datasheet's boot mode table that the MPU can be booted through UART: – USART2/3/6 and UART4/5/7/8 on default pins Nevertheless, I wasn't able to find which are the default pins for the UART interfaces, on the datasheet or reference manual. Where can I find those? STM32MP15-DISCO schematics uses UART4 pins PG11 and PB2 routed back to the Serial/USB bridge, are those UART4 by default?   GPIOx_AFRH/L reset value is 0 for all ports, and no UART pin is selected on AF0.

I'm using i2c interface to communicate with a eeprom memory, by dma. It's working, however, when I put a wrong address to write in the memory (to test the errors), I get as return HAL_ERROR, but the function HAL_I2C_ErrorCallback (that i implemented) does not called.How can I get a callback from this function in a error situation?Part of my code is available below:status = HAL_I2C_Mem_Write(&hi2c3, 0xB4, (0<<8), 2, dataWrite, 270, 1000); //Wrong Address   void HAL_I2C_ErrorCallback(I2C_HandleTypeDef *hi2c){ HAL_UART_Transmit(&huart1, errorMsg, sizeof(errorMsg), 1000); }

Hello, I'm having trouble inserting my own header files. No error is displayed in the STM32IDE when compiling, but when I compile in the GFXTouch, the errors are in GFXTouch.png.I've already included the paths include in c and c++. How can I include my header files in GFXTouch.Thank you

I am developing on the STM32U5 family and i need to use UCPD. As far as I know the UCPD middleware is no supported on this family, so I need to implement my functionality using the LL driver for the UCPD module. I am not experienced with usb power delivery. It would be nice to see and example of the ll_ucpd usage.

Hi,May I exchange the in/exit of the EMIF03? As the pin name indicate there are in pins and exit pins. But from the internal diagram, the ins and outs are exchangeable.Thanks.

I'm using the STM32F746 discovery board and I'm trying to display the images captured by the camera. The problem is that only one frame is displayed on the LCD display. The camera don't send more captures I think.Code of the DCMI setup:1.- Fist I setup the DCMI peripheral using the CubeMX wizand integrated in the STM23CubeIDE and the output of the wizard is:static void MX_DCMI_Init(void){ hdcmi.Instance = DCMI; hdcmi.Init.SynchroMode = DCMI_SYNCHRO_HARDWARE; hdcmi.Init.PCKPolarity = DCMI_PCKPOLARITY_RISING; hdcmi.Init.VSPolarity = DCMI_VSPOLARITY_HIGH; hdcmi.Init.HSPolarity = DCMI_HSPOLARITY_LOW; hdcmi.Init.CaptureRate = DCMI_CR_ALL_FRAME; hdcmi.Init.ExtendedDataMode = DCMI_EXTEND_DATA_8B; hdcmi.Init.JPEGMode = DCMI_JPEG_DISABLE; hdcmi.Init.ByteSelectMode = DCMI_BSM_ALL; hdcmi.Init.ByteSelectStart = DCMI_OEBS_ODD; hdcmi.Init.LineSelectMode = DCMI_LSM_ALL; hdcmi.Init.LineSelectStart = DCMI_OELS_ODD; if (HAL_DCMI_Init(&

STLink Debugger is not listed in Keil for NUCLEO-L55E (Cortex M33) project, but if I open any other project for other STM32 Cores, I can see the STLink debugger in the "Debuggers" list.It was working before, I have now a new setup and I cannot find the STLink option, so I cannot program/debug my codeAny recommendation?

Using an STM32F107 without an operating system. Looking for an open source SSH library that can be used along side LwIP.Has anyone had any luck doing this previously?

I am having some issues getting meaningful values out of my ADC. At the moment I am capturing ADC samples with the polling mode with the ADC pin being set to approximately 3.2v and 0v. When I check the sample results I am seeing around 20000 for captures taken with the ADC input pin is set to 3.2v and around 14000 when the ADC input pin is set to 0v. Below I have included the current settings for ADC2:static void MX_ADC2_Init(void) {   /* USER CODE BEGIN ADC2_Init 0 */   /* USER CODE END ADC2_Init 0 */   ADC_ChannelConfTypeDef sConfig = {0};   /* USER CODE BEGIN ADC2_Init 1 */   /* USER CODE END ADC2_Init 1 */   /** Common config */ hadc2.Instance = ADC2; hadc2.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV1; hadc2.Init.Resolution = ADC_RESOLUTION_16B; hadc2.Init.ScanConvMode = ADC_SCAN_DISABLE; hadc2.Init.EOCSelection = ADC_EOC_SINGLE_CONV; hadc2.Init.LowPowerAutoWait = DISABLE; hadc2.Init.ContinuousConvMode = DISABLE; hadc2.Init.NbrOfConversion

Hello, I have one ST25R3916B which is connected to 16 PCB spiral antennas, through DPST relays. It works well. To select the antenna I want to use I just power that relay and leave the other relays off. However, the sound of the relays clicking is not advantageous. So I'm looking at antenna MUX ICs from Skywors, pSemi, etc. (example PE42582) but these are all 8:1, so I would need to use one on each RF output of the ST25R3916B.Questions:What do I modify in the driver code to support single ended operation?In the driver code, how do I switch on the fly between the two single-ended outputs?How do I change the antenna match to support single ended operation? I'm using the AAT with variable capacitors from the NFC08 reference design.

Hi... for some reasons I cant regenerate my code from CubeMx but I need to change crystal 8M to oscillator 14.7456... in spite of replacing the clock function (void SystemClock_Config(void) ) with new one, my project does not work. what other changes do I need to consider for changing the clock in a project generated by CubeMx?thank you in advance

Hello *,I'm currently trying to use a micro-sd card breakout board on my Nucleo-H743ZI to store some data using the SDMMC interface and the FatFS middleware v0.12c (The breakout board is just here for the pull-up resistors on the lines).I've setup the SDMMC1 interface without any IT or DMA, and a clock running at 25 MHz from a PLL divider.So my problem is that, during the Init phase (1-bit SD mode running at 400KHz max) the "basic" commands that receive a response on the CMD line are fine, but as soon as I run an ACMD (CMD55 followed by CMD13 is my first problem), the R1 response is read, but then the data that is supposed to be read is never read in the FIFO, thus blocking the polling loop.I've seen on the scope that the command, R1 response and D0 line have content on them and that the CLK line is less than 400KHz (but close enough).I've checked the DPSM with a breakpoint just after the ACMD13 is sent, and the registers indicate that the state machine is not in Idle, so I guess it sh

Hello. I'm trying to make a code to show some menús (configuration and user menús) in a LCD screen, but something goes wrong when I try to write the year, and read it later, from the RTC calendar registers.My main code begins with the cube MX function that sets a initial value to all the RTC calendar fields:sTime.Hours = 0x09; sTime.Minutes = 0x30; sTime.Seconds = 0x00; sTime.DayLightSaving = RTC_DAYLIGHTSAVING_NONE; sTime.StoreOperation = RTC_STOREOPERATION_RESET; if (HAL_RTC_SetTime(&hrtc, &sTime, RTC_FORMAT_BCD) != HAL_OK) { Error_Handler(); } sDate.WeekDay = RTC_WEEKDAY_FRIDAY; sDate.Month = RTC_MONTH_MARCH; sDate.Date = 0x31; sDate.Year = 0x23;   if (HAL_RTC_SetDate(&hrtc, &sDate, RTC_FORMAT_BCD) != HAL_OK) { Error_Handler(); }Later, I can configure the time and date, using some enums to do it more human, in the exit section of a configuration menú:if (new_exit == 1) { date_final.Date = day_enum; date_final.Month = month_enum; date_final.Ye

I am trying to achieve hard real-time under 100us on the STM32MP157f-eval, specifically, on the Cortex A7 dual core.Note: I specifically target the Cortex A7 cores because the M4 is already taken for other tasks which requires much smaller latency.What I did so far is:Build the Yocto openst-linuxAdd Preempt-RT patchAdded several software: irqbalance, tuna, hiccups... to monitor and tune the system.Isolate one coreTested high-priority process, also IRQ. Tested with internal clock and external oscilloscope.Tried to disable most driversAfter all those efforts, the jitter did not improved, and I still get >1ms jitter when applying load for enough time.------------------------------My next step is to ensure that the cpu frequency is not throttled. I read https://wiki.st.com/stm32mpu/wiki/How_to_change_the_CPU_frequency but it's not yet clear to me how to check and set this.Also, most general questions found on internet don't seem to apply to this architecture.How to check that cpu freque

Hello, i want to measure the power consumption of STM32F767zi only MCU Part using X-NUCLEO-LPM01A. The step of manual says to "open the SB110" by default SB110 is ON what are the ways to make it open ? can we do it through wires or some jumpers? 

This was reported for older CubeIDE version and now reproes in v 1.12.When the selected builder is "internal", the build runs normally, but .bin and .list files are not created (the checkboxes are enabled and selected), the size info is not printed.However, the user post-build command is executed normally.Workaround: .bin, list and size can be created in user port-build script.Would be nice to fix it - I prefer the internal builder because it does not drop a lot of junk useless artifacts.

Moving from a audio effect prototype based on the STM32F407 to the STM32H757. Did a lot of stuff on the F4 with audio but on the H7 I'm getting stuck and can't get a simple audio loopback with DMA. I'm using Cirrus Logic's CS5343 and CS4344 as external ADC/DAC connected to the I2S interface. I2S data frames are read and written in memory with DMA configured in circular RX/TX mode.Without DMA, audio loopback is OK. However, with DMA, the RX buffer isn't filled. The half complete and complete callbacks are triggered tho.I'm aware that DMA can't access DTCM RAM and that with cache enabled, data coherency should be taken care of thanks to the MPU configuration and modification of the linker script :MPU creates a region of 128kB device memory type (TEX : 0b000, not cacheable, bufferable, shareable)RX and TX buffers (8kB each) subsections have been placed at 0x30010000 and 0x30012000 (SRAM1 in D2) in the linker script.I tried to move the buffers in other RAM domains, make the MPU Region as s

I have a specific application where I need to detect the presence (or absence) of a ISO15683 tag at a range of about 10 cm using a Molex 146236-2102 NFC Antenna. Is there an appropriate STMicro product?
