STM32 MCUs Products

Anyone who knows that Development kit for below given part number(Connect D[7:0], PCLK, HSYNC, and VSYNC), and Can we video streaming via USB?STM32F407VET6.  

I have an STM32L011 on a board I am developing.I can enter the bootloader no problem, as per AN2606/AN3155.  I am using USART2, 57600 baud.I can program FLASH/erase FLASH/read FLASH - all works as expected.I note that the bootloader reserves 2048bytes of SRAM, I assume it's the addresses 0x2000_0000 .. 0x2000_07FF.When I try to use the memory read command to read from anywhere in SRAM (whether the bootloader reserved area or any other address) I get a NACK just after the address+xor-check-byte.I believe the protocol is correctly implemented because the same thing works reading from FLASH addresses (e.g. 0x0800_0000).Is there a known issue here (I have seen other posts on this forum with similar problems on other STM32 parts - but these are either unresolved or they are trying to read from the reserved SRAM which is expected to be NACK'd). 

I am working with a dual core STM32H755 and attempting to create a shared memory location for the two cores to access. I am attempting to do this by modifying the linker script.  I have added the following lines to the M7 core linker script, in the SECTIONS block:/* Shared Memory section for inter core comms */ .sharedRAMsection 0x30040000 : { .= ALIGN(4); KEEP(*(.sharedRAMsection)) . = ALIGN(4); } > RAM_D2 Then in one of my .c files, I have declared the following global variable:RegisterMap_t __attribute__((section(".sharedRAMsection"))) g_RegisterMap; However, when I debug I can see the address of this variable has been assigned to memory location 0x24000064, as seen in the watch window: I am using visual studio and visual GDB, and I am debugging with 2 separate VS instances for the two cores. Is there something else that I need to do in order to get this variable into the correct memory location? Thanks 

用SPI+DMA驱动AD4001，用片选信号代替 CONV，采集一个正弦信号。Normalnormal正常，循环模式却不对，求大佬解答！！Normal模式下，每次在 HAL_SPI_RxCpltCallback 函数里面重新启动数据正常，能看到正弦变化规律                                 循环模式下数据就不对了，采集的同样一个交流信号，我在半传输完成回调里面查看，按道理后半部分的数据应该是正常的正弦变化才对，实际却不是，但是去采集直流时又是正常的。                PS：缓冲区开的1200，感觉应该不会更新这么快，就算更新应该局部的数据具有正弦规律    我得猜想：是不是因为我再keil里面是打断点查看的数据，并不会停下SPI+DMA 在循环模式下的硬件工作，导致后台一直在更新，keil显示的数据其实不对配置：配置的区别只修改了DMA是正常还是循环void MX_SPI1_Init（void）{/* 用户代码开始 SPI1_Init 0 *//* 用户代码结束 SPI1_Init 0 *//* 用户代码开始SPI1_Init 1 *//* 用户代码结束 SPI1_Init 1 */hspi1.实例 = SPI1;HSPI1 的。Init.Mode = SPI_MODE_MASTER;HSPI1 的。Init.Direction = SPI_DIRECTION_2LINES_RXONLY;HSPI1 的。Init.DataSize = SPI_DATASIZE_32BIT;HSPI1 的。Init.CLKPolarity = SPI_POLARITY_LOW;HSPI1 的。Init.CLKPhase = SPI_PHASE_1EDGE;HSPI1 的。Init.NSS = SPI_NSS_HARD_OUTPUT;HSPI1 的。Init.BaudRatePrescal

Hello Tesla I need to run M4 from 0x08000000  and then M7 from 0x08100000. Is there any example ?   Exactly I v'done my BOOT that runs on M4 (0x08000000) loads the Flash , then jumps into M4 (0x08040000). Now i have to run M7 from 0x08100000, but i don't know how... Please help :)

I am trying to debug some functions to write to the memory mapped QSPI. When I go to debug it, I notice that before any functions even run the QPSI is in HAL_QSPI_STATE_ERROR, therefore I cannot test my code to see if is running because it is dependent on the State of the QSPI. My QSPI is a WinBond25Q128JVSQ. Is there a way to trouble shoot this?

Are the steps followed for RTC calibration the same for crystal and temperature variation?How is the calibration register value selected for temperature variation?

I have selected the RTC calibration as 512Hz. Will I be able to perform RTC smooth calibration if my frequency obtained on the RTC calib pin is beyond the range 511.75Hz - 512.25Hz. How do I calibrate the RTC beyond this range ??  

When trying to program the STM32L4P5RE, I get an assertion failure when trying to program the second bank like this:HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, address, data)This call fails if my address is in the second bank `0x08080000`.  Looking at the source code, I get an assertion failure here: static void FLASH_Program_DoubleWord(uint32_t Address, uint64_t Data){ /* Check the parameters */ assert_param(IS_FLASH_PROGRAM_ADDRESS(Address)); <---- HEREI understand when DBANK (Or DB1M) is set, we cannot read the other bank.  So how are we supposed to actually program it?

Hello, I am working with an STM32G4 microcontroller and noticed an unexpected behavior regarding Bit 20 (BFB2) in the User & Read Protection Option Bytes.According to the reference manual, BFB2 is a read-only bit.After performing an option bytes erase in Keil, I expected BFB2 to be cleared to 0 (default).However, after a system reset, I observed that BFB2 is set to 1.I would like to understand:Who sets BFB2 to 1 after an option bytes erase?Is this controlled by bootloader behavior, internal flash controller logic, or some default hardware mechanism?

I have two Nucleo boards that are connected with a CAN bus (Transceiver SN65HVD230). I would like to communicate with standard CAN, eight data bytes, data rate 50000 bit/s. For the F407 all TX & RX events are triggering (reused old working code) the CubeMX settings (HCLK 168 MHz, periphiral clk 42 MHz) are: The G431 is not working as expected, the CubeMX settings (HCLK 170 MHz, peripheral clocks 170 MHz) are: The G431 TX/RX interrupts are working only in external Loopback mode in normal mode nothing triggers. Some code for the configuration of the G431 CAN:   HAL_StatusTypeDef CAN1_Start(int8_t CAN_HW_init) { HAL_StatusTypeDef status; FDCAN_FilterTypeDef filterConfig; if(CAN_HW_init == 1) { MX_FDCAN1_Init(); } // Configure Rx filter filterConfig.IdType = FDCAN_STANDARD_ID; filterConfig.FilterIndex = 0; filterConfig.FilterType = FDCAN_FILTER_MASK; // FDCAN_FILTER_RANGE; filterConfig.FilterConfig = FDCAN_FILTER_TO_RXFIFO0; filterConfig.FilterID1 = 0x000; filter

I'm trying to understand how the CSR register works. I though initially that the various reset reason bits are mutually exclusive. That turns out not to be the case. For example, I'm seeing SFTRSTF and PINRSTF together, and also BORRSTF with PINRSTF. I'm curious to know the possible combinations and what they mean.Looking at the reference manual, it looks like the bits *are* mutually exclusive, with exception of PINRSTF. This is presumably set because the other signals are ORed together and used to create a pulse on NRST. Is this reading of the manual correct?There is no PORRSTF in the CSR register. My guess is that a POR is signalled by having PINRSTF alone set. Is this correct?On a not unrelated topic, what is the minimum Vdd at which the flash can safely be written? I'm seeing ECC faults and flash corruption, which seem to be due to writing a flash log entry when the battery is almost exhausted. I want to mitigate against this by detecting BOR or another low voltage condition,

Hi,I am using nucleo-l476RG board.I am new to USB audio, I am trying to create USB Audio class (Speaker/MIC) using HAL. I am sucessfully able to create a node for speaker and MIC in my laptop. But unable to send and receive the data over USB. Can anyone suggest me any example or any documentation which can help me to achieve my goal.Thanks 

I have WeAct studio's STM32h750VBT6 board. i am trying to access Sandisk's 64 GB MicroSD card (formatted as FAT32) through MicroSD card Adapter using SPI1. I am not able to access memory card. i have enable SPI1 and made enable PB1 (SD_CS) as gpio_output and made it high. Also cross checked the hardware connection too, they are properly connected. i have provided 5v to Micro SD card adapter. still it issue persist. while debugging, i observerd fres is showing FR_NOT_READY. i am not able to figure out what's the issue. i have tried pull up on all pins as well  as pulldown but still the same. tried different prescaler too but same. i have use Tutorial-STM32CubeIDE-SD-card for reference.fres = f_mount(&FatFs, "", 1); if (fres != FR_OK) { printf("f_mount error "); while(1); } 

I made a custom board using a C091KCT6. I assumed I would be able to figure out a way to display data in real time using printf. Unfortunately, I did not make provision to expose PA2 and PA3 (or indeed any pins other than the ones used by my board). PA2 is in any case in use as SPI1 MOSI. So I have pretty much accepted that I need to make a new custom board, and I am keen to ensure that I will be able to use printf this time!I believe that two good solutions are to buy the STLINKV3-SET and either a) re-design the board to expose the PA2 / PA3 UART to that ST-LINK or b) re-design the board with an MCU that has a SWO pin and expose that to the STLINK-V3.I would like two kinds of help, please: if I do not need to buy a new debugger or re-design the board, it would be great to hear how I can use printf with the setup I have, or avoid one of i) buying a new debugger and ii) re-designing the board.If I do need to buy a new de-bugger and re-design the board, it would be great t

Hallo, the information written on rtcbackup register, is retained when micro is powered off?Or the information will be lost?

Split from:https://community.st.com/t5/stm32-mcus-embedded-software/how-to-use-analogue-pins-not-adc-to-read-voltage/td-p/792208Please keep to one question per thread.Hi, One more related question, I have changed the pins and now i am reading the voltage but all the pins are giving me a voltage of 1.7v while my actual value is 1.2-1.4v. I use Vref internal 3v. Can anyone guide me what i am doing wrong?I think it has to do with the value of my Vref How to use the STM32 ADC's internal reference volt... - STMicroelectronics CommunityI have read this but its not sufficient. I just have a simple question in order to read any voltage value under 3v what Vref internal i shoul use? Thanks in advance !

Hi,I am working with a custom board with the STM32L431CCU6 mcu. The bord consist of the mcu and 2 i2c units and one SPI.The board also has pin headers for BOOT0, SWDIO and SWCLK.Sory for paint... I am using the CubeIDE and a ST-LINK V2for programming the board and have successfully programed Blink on it. This was not problem free however since my coputer sometimes did not recognised the ST-LINK and sometimes failed to upload. Unfortuanatli I do not remember those errors in details.After succesfully uploading a program for i2c communication I could not program the board any more. The error i receive from the IDE is:STMicroelectronics ST-LINK GDB server. Version 7.9.0 Copyright (c) 2024, STMicroelectronics. All rights reserved.

板：STM32G431 NUCLEO-64我的目标是在 ADC1 和 ADC2 上实现 4 MSPS 的采样率。通过使用交错采样，我的目标是获得 8 MSPS 的有效采样率。虽然我知道这可能与数据表中针对多通道 ADC作的声明限制不严格一致，但我相信这种差异与我遇到的问题没有直接关系。根据数据表中的图1、ADC 时钟应低于 52 MHz。图 1在我的设置中，我在交错模式下使用 TIM + DMA + ADC，配置如下：定时器触发频率：4 MHzADC 分辨率：12 位ADC 时钟：60 MHz采样时间：2.5 次循环我的输入信号是由板载 DAC 生成的连续正弦波，频率为 50 kHz。在查看与 timing calculations相关的 datasheet 部分后，总转换时间似乎应该在7.5 cycles 左右。但是，STM32CubeMX 只允许采样时间设置介于 1 和 12 之间的整数值，因此我选择了 7 个周期。以下是我观察到的：当我将“Delay between 2 sampling phases”设置为 7 个周期时，采样间隔看起来不规则，并且与预期的交错模式不匹配（参见图 2）。当我将“Delay between 2 sampling phases”设置为 12 个周期时，得到的采样间隔看起来是均匀分布的（参见图 3）。  图 2 Figure 3What I want to understand is:What is the correct value to set for “Delay between 2 sampling phases” to achieve ideal interleaved sampling with evenly spaced samples?  

Dear forum mmebers,I am trying to use an STM32U5G9 MCU to drive a Ti SN65DSI86 DSI to eDP converter with no success.Previously I have evaluated the SN65DSI86 with a Xilinx FPGA as a DSI source where it was working perfectly from 640x480 to 1920x1200 resolution at 60Hz refresh rate. The line rate was up to 900Mbps/lane. At 640x480@60Hz I used 2 lanes and 250Mbps/lane. The SN65DSI86 can be configured to output the VSYNC on one of its GPIO which can be used to verify that DSI data is at least partially correct.I have also succesfully evaluated the STM32U5G9J-DK1 evaluation board with its display (round, 480x480) so both the STM32U5G9 and Ti SN65DSI86 works.Now we have manufactured an extension board for the STM32U5G9J-DK1 which has the Ti SN65DSI86 and a DisplayPort connector to drive a monitor. I am trying to use 640x480@60Hz and the STM32's internal test pattern generator in the DSI. Now I can see that the 60Hz VSYNC signal is present on the SN65DSI86 but it gives no picture at all.What

Hello,I'm using in my projects with ports PA10,PA11 (for Logs - uart), and PB14 and PB15 as normal GPIO.They didn't works.After long troubleshooting.... I found out that is because these ports are supply separately by the VDDUSB pin which was disconnected.I couldn't find the reason in the datasheet, I'll be happy to understand the construction and the reason.  

I2C slave that needs to act differently depending on the first written byte in a write request with unspecified length [1 or 3 bytes]Hi!I am trying to emulate MCU master to I2C slave devices using two "black-pill" MCUs  (STM32F411CEU6 @100MHz) and STM32CubeIDE (STM32Cube_FW_F4 V1.28.1).I have mainly studied the following I2C tutorials (part1 - part6): https://controllerstech.com/stm32-as-i2c-slave-part-1/  I have managed to get the following scenarios to work as expected(M: Master, S: Slave, the slave operates in interrupt mode):M perform a simple read from S M [Read Request - 2B] -> S[Detects Read Request and answers with 2B or more if M does not stop]M reads 3 times from Slave with different offsets (S continues to send incremented data with offset until M stops)M[Write offset 1 -> 2B] -> S[Detects/Determines offset and Transmits data correctly]M[Write offset 2 -> 2B] -> S[Detects/Determines offset and Transmits data correctly]M[Write offset 3
