STM32 MCUs Products

Hi all   Is it correct that the flashing of STM32C071CB is not quite readily available?  I am using the newest stm32cubeprog, version 2.18.0, or Keil MDK version 5.41.   In both cases, I have tried to make a connection to the captioned MCU but I got failure in connection. In particular, in MDK 5.41, I get this screen shot: That the flashing driver of STM32C0x_64 is not the appropriate driver to being used for the 128K part.   I did look into the corresponding file folder, and I did locate STM32C0x_128.FLM file but some how I cannot get this in the file list for the selection. &n

I’m interfacing the STM32H755ZI-Q Nucleo board with an MTFC8GAMALNA-AAT eMMC. What configurations are necessary for this interfacing? I’m also getting warnings in the RCC configurations. Could you guide me on the settings needed for SDMMC1 and FATFS, and let me know if there are any additional configurations required?

Hi everyone,I am working with a NucleoU5A5 and a W25Q16 flash chip in quad SPI mode (using the OctoSPI peripheral). For a couple of days I couldn't get it to work reliably: reading multiple bytes would fail on certain byte values coming from the flash chip. Specifically it would fail if three or four data lines were pulled high, but not if fewer than three data lines were pulled high. E.g. reading the value 0x03 would work fine (2 data bits high), but 0x07 would fail (3 data bits high).  Failure in this case means that the flash chip just stops responding at all. It's not like the signal gets distorted in any way (I looked at the analog signal with a scope). As I am still in an exploratory phase, the flash chip is connected to CN10 of the Nucleo board with 100mm wires. I noticed exactly the same behavior with clock frequencies from 100 kHz to 16 MHz.I found

The FDCAN (in my case fdcan2) for a custom board based on STM32G474RCT that I am working on does not seem to work as expected. The transmission of messages is working OK. I can receive the test message from the board over to the host PC CAN sniffer at 250K baud. I have tried to use the example project for the Classic CAN Networking using FDCAN.So though transmission is working, reception requires an interrupt which never comes. I have traces from the oscilloscope that confirm the GPIO pin responsible for FDCAN2 Rx is receiving signal from the on board CAN Transceiver, but the controller does not respond reception with the interrupt call.I have attached the bare minimum example as a STM32CubeIDE project to help find a solution in my situation.Thanks for having a look.

I use F407G-DISC1 and RTC values dont change i have. In project i have I2S sound filtering and button that displays number on LEDs in binary, when button is pressed. But nothing happening on button press. Did i missed something?     /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * <h2><center>© Copyright (c) 2019 STMicroelectronics. * All rights reserved.</center></h2> * * This software component is licensed by ST under Ultimate Liberty license * SLA0044, the "License"; You may not use this file except in compliance with * the License.

I'm from an institution where we use STM32 as our regular teaching material. But I have noticed that many of our boards are getting this issue, Even though it's physically perfect. This is making a lot of ewaste for us. I have tried all the method searching in Goolge (for example: using the reset button while pressing connect)But all these

my platform is STM32F446, it play as a USB host at full speed, and the pins are PB14 PB15.I use ST USBH library to implement a USB AOA class.But I found that everytime when the MCU try to send a Setup transfer and DATA0 transaction, the DATA0 is corrupted.from logic analyzer we seen below, the DATA0 bit number is wrong.further more, there are 20+ bits 170us later.

Symptom: STM32H7S78-DK board includes a 32MB PSRAM (APS256XXN-OBR-BG() connected to HEXASPI. Somehow only the first 4MB is accessable.   How to reproduce the error: Use the template project provided in "STM32Cube_FW_H7RS_V1.1.0\Projects\STM32H7S78-DK\Templates\Template_XIP" add the following code in the app's main.c:   /* USER CODE BEGIN 0 */ #include <stdbool.h> bool TestExRam() { unsigned char* address = (unsigned char*)0x90000000; int ramSize; ramSize = 32*1024*1024; // failed at 0x90400000 which means only 4MB RAM is accessible. //ramSize = 4*1024*1024; // passed test. unsigned char* begin = address; unsigned char* end = begin + ramSize; unsigned char* p = begin; char c = 0; while(p < end) { *p = c; p++; c++; } // Check whether the data is correct: c = 0; p = begin; while(p < end) { if (c != *p) { // error! retu

Hi I am developing a board with two MCU on it (stm32h755), and I am going to programme these two controllers from the same connector using only two lines (SWDIO SWCLK), I have connected same CLOCK line to both MCUs directly, and the SWDIO to a switch to select which MCU to programme, is this connection fine??Also this MCU has the CANFD, but I want to use normal CAN, is it fine to connect it to a normal CAN transceiver not CANFD one??.thanks  

Hello Community,I'm using an STM32G474RE MCU with FDCAN0 to set up CANopen communication for a sensor node device. The setup is designed to cascade multiple sensor devices on the same CAN bus, each with a unique node ID, so they can transmit data independently.Currently, I have two devices connected in a simple cascading configuration, both operating as CANopen nodes with different IDs. No CAN master or analyzer is connected, as these sensor nodes are meant to operate autonomously on the bus.Here is my FDCAN initialization code:   void MX_FDCAN1_Init(void) { FDCAN_FilterTypeDef sFilterConfig; /* FDCAN1 parameter configuration */ hfdcan1.Instance = FDCAN1; hfdcan1.Init.DataPrescaler = 12; hfdcan1.Init.NominalPrescaler = 12; hfdcan1.Init.NominalTimeSeg1 = 13; hfdcan1.Init.DataTimeSeg1 = 13; hfdcan1.Init.ClockDivider = FDCAN_CLOCK_DIV

Hi,We want to use the Type C connector with STM32 as "STM32 USB2.0 host conversion for USB Type-C platforms" for 5V, 500mA application. We have got one application circuit in STM32 application circuit. (Fig 11)Introduction to USB Type-C® Power Delivery for STM32 MCUs and MPUs - Application noteIn this circuit, RP1 and RP2 pullup resistors are pulled up to 5V and connected to ADC pins. But, the ADC pins are 3.3V compitable. Can you please let us know is it fine to Pull up the ADC pins to 5V rail?.Thanks.

I am attempting to talk to BMP280 over SPI using Nucelo-F401RE. I am using SPI2 on the F401RE board to do so, I am able to read from it correctly but I can't seem to write to it in order to communicate with it. My code is as follows   /* USER CODE BEGIN WHILE */ HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0, GPIO_PIN_SET); // Setting this high, to not select the chip char send_buff [8] = {0,0,0,0,0,0,0,0}; char recieve_buff_0 [8] = {0,0,0,0,0,0,0,0}; char recieve_buff_1 [8] = {0,0,0,0,0,0,0,0}; HAL_StatusTypeDef ret; while (1) { HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0, GPIO_PIN_RESET); // Setting this low to enable the chip send_buff[0] = 208; ret = HAL_SPI_Transmit(&hspi2, send_buff, 1, 1000); // Reading the register ID ret = HAL_SPI_Receive(&hspi2, recieve_buff_0, 1, 1000); // I receive 88 (0x58) back which is correct HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0, GPIO_PIN_SET); // S

Hi. I'm trying to use STM32H573IIKxQ's SPI using HAL.I've noticed that the HAL library disables the SPI after each transfer which causes the SCK pin to go high and goes low again before the next transfer, which causes an extra bit being shifted to the slave device:I tried to remove the line from HAL lib that disables SPI after finishing the transfer which cause the next transfers to not happening. is there any solution for this? I mean is it possible to keep SPI enabled the whole time and then use it in different manners (pulling, IT, DMA, single byte transfer, ...) ?

Hi All,I was experimenting with the inbuilt temperature sensor on STM32F4 DISCOVERY board. The sensor is connected to ADC1_IN16 (16th channel of ADC1).I wrote a basic C program (attached below) and was able to get the sensor working perfectly fine.(I have configured 3 of the 4 on-board LEDs to change color as the temperature varies, this is why you would see the GPIO config part as well)   #include<stdint.h> #include<stdio.h> int main(void) { //Variable Definitions uint32_t* GPIO_MODER = (uint32_t*)0x40020C00; uint32_t* GPIO_ODR = (uint32_t*)0x40020C14; uint32_t* RCC_CLK_AHB1 = (uint32_t*)0x40023830; uint32_t* RCC_CLK_APB2 = (uint32_t*)0x40023844; uint32_t* ADC_CR2 = (uint32_t*)0x40012008; uint32_t* ADC_SQR3 = (uint32_t*)0x40012034; uint32_t* ADC_SQR1 = (uint32_t*)0x4001202C; uint32_t* ADC_CCR = (uint32_t*)0x40012304; uint32_t* ADC_DR = (uint32_t*)0x4001204C;

Hi, I am integrating the STM32H7S7L8H6H in a custom board.  In the reference manual I found two settings which I am looking for clarification for: 1) SBS_PMCR has a AXISRAM_WS bit to enable a single wait state for the AXISRAM.  I do not have ECC enabled so this bit determines whether or not a wait state is added for AXISRAM accesses.  With the bit set the reference manual states: "One wait state added when accessing any AXISRAM with ECC = 0. In this case, refer tothe datasheet for maximum frequency."  I cannot find any relevant maximum frequency in the datasheet (DS14359 Rev 2) but I would have thought the maximum frequency would apply to the situation where there was 0 wait state rather than 1? 2) PWR_CSR2 has XSPI_CAP1 and XSPI_CAP2 settings to enable or disable a capacitor in the XSPI ports.  Again the datasheet is referenced but I cannot find any description of this setting there.  Does

Hello guys, I am working on project to update the STM32G070 over the air. So basically I receive the binary on ESP32 and then forward the binary over UART to the STM32. I have used pattern 11 to enter the USART Bootloader of the STM32. Then sending the 0x7F to get in synchronization with the STM32.By only controlling the BOOT0 Pin I cannot enter the USART Bootloader. By pulling the NRST Pin and the BOOT0 Pin I can enter the USART Bootloader successfully . So is it possible to enter the USART Bootloader without hardware reset ??

I am using the STM32F401RE.Currently, I purchased an external USB device, replicated the USB circuit that was installed by default, and connected it to the following pins:{CN7-5 (+3.3V)CN7-17 (PA15)CN10-14 (PA11)CN10-12 (PA12)CN7-19 (GND)}I tested to see if it would be recognized on the PC side, but it was not recognized.I added the pin activation process for PA11 and PA12 in the main.c program, but it was not recognized.Does anyone know why it is not being recognized by the PC?

Hello,I would send the packet between a client and a server with over 20 bytes.I have searched all communities and haven't fount out any actual solution. (Such as, doing 'aci_gatt_exchange_config()' function or exchange ATT_MTU value)Is it possible to increase the maximum size of any packet sent between a client and a server? Thanks,

Hello Experts,Here am using one slave which has SMBUS interface for data transmitting.I am using STM32F103RBT6 for SM BUS and generating the code with STM CUBE MX ,but am unable generate the working code with it and its generating error code.I updated the STM32F1 Patch and Cube Mx also still am unable to generate the code.Does STM32F1 has SMBUS with HAL libraries?

Hello,I’d like to configure two UCPD ports on STM32G0B1 in STM32CubeMX. I’m working on a custom board with two TCPP03-M20 (dual role). However, I’ve noticed that STM32CubeMX seems to support configuring only a single UCPD interface. I’ve tried setting it up, but I can’t figure out how to make it work for both ports. Is it possible to configure both UCPD interfaces manually in the code, or am I missing something in CubeMX? Any guidance or examples would be greatly appreciated.ThanksVladislav

About parallel synchronous transmission using GPIO and DMA.We want to achieve 8-bit parallel synchronous transmission using GPIO and DMA. However, we could not find any program samples that could serve as reference.Is there a sample somewhere that can serve as a reference?Also, what kind of settings are necessary to achieve 8-bit parallel synchronous transmission using GPIO and DMA?

I've designed a board that has a STM32L476.This part is supplied using a triple system of dual battery + power ( when it is available)We've manufactured more than 20k units of them and they are working okA few days ago 2 boards came back to our design lab that exhibit the following symptoms :-> The RTC keeps counting past 23:59:59 until 39:59:59-> Neither on 23h nor 39h rollover the day gets increased-> When trying to set the time we get the following data: If the time is less than 20h, 20h get added to it Else the hour is correctly set-> Rollover behavior don't changesIf we force a reset of the CPU, the problem dissapears.More data: -> The RTC access is done using HAL libs. -> The RTC isn't reset when setting the date/timeWe still have one untouched board for testing, but any try to use a debugger would trigger a CPU reset, making the probblem dissapear.
