STM32 MCUs Products

Hello everyone,I have a question about the STM32C011J4M6 in S08N package.I am developping a PCB with this MCU and want to use an LSE like in the picture below.Then I also want to program and debug my MCU with an stlinkv3 and will use the SWD debug so the 2 wire SWCLK and SWDIO will be connected to PA13 and PA14.The problem is that in the pinout view below, PA14 and OSCX_OUT are on the same pin.

Hi guys!We are running a project using STM32G0 MCU-s. We used STM32G031 in the previous iteration, but, due to budget reasons, we now ended up with STM32G030-s, beleiving these are basically interchangeable for our purposes. Due to some board error, we now need to disable the NRST pin (or, rather set it up to be a GPIO in this case). On the older G031 boards, we can perform this from code through the option bytes, but to our surprise, the G030 manual misses these bytes altogether. Using the older STM ST-Link utility, we were able to program the bytes on a test device somehow, and set up proper functionality, but I have a bad feeling about this. We have quite a few production devices where the programming pins are not accessible anymore, and we can only disable NRST with a software update. If we brick them, there's no way of bringing them back.So... is there any way to safely set up NRST as GPIO on G030s from software? Is it a s

Hi,I am switching PB12 on/off with 1 second delay on STM32F030C8T6. Measuring with the multimeter, the HIGH state is only 0.2 volts, even though Vdd is 3.3V. I have turned off all things that could be drawing too much power from the MCU. Other pins output a voltage very near 3.3V. There are no external connections with PB12, only a 10k pull-up resistor. What could be causing this?

I have defined PE9 as belonging to Timer 1;I setup timer 1 as PWM as shown above.When I enable the timer, nothing happens at PE9.I tried setting force  high; no changeWhen I define PE9 as standard output forced high, it goes high.  So I know that the pin is connected correctly to the board.But I'm not doing something to correctly setup PE9 as a PWM output 

I am tring to write a code for stm32f401cb which will blink the led when i press the led and when i leave pressing the button,it will turn out the led.I have set channel ahb1 which connects to port a and b in my microprocessor f401cb and i chose input type pull down in port a and led is connected to port b.But my led is not blinking in anyway.where is my mistake you think?My led is not blinking when i press the button.it is always turned out As you can see in the picture am holding the button but there is no response on the led.Note:Port a is selected as input and port b is selected as output and both ports are controlled with their 0 (zero) pins. my code is like that Why i cant get a response on the led?

What am I doing wrong?Why is PWM don't work on the STM32F767ZI? RCC->APB2ENR |= 1; // Enable clock for TIM1 on APB2. RCC->AHB1ENR |= RCC_AHB1ENR_GPIOEEN; // Enable clock for GPIOE port on AHB1. GPIOE->MODER &= ~(1 << 18); // Clear/reset PE9 mode. GPIOE->MODER |= (2 << 18); // Set PE9 mode. // Enable alternative function AFIO. Connect TIM to the pin accordingly! GPIOE->AFR[1] &= ~(0xF << 4); // Clear bits 4 to 7. GPIOE->AFR[1] |= (1 << 4); // Set bit 9. TIM1->PSC = 216 - 1; // Set prescaler for > 10KHz. TIM1->ARR = 100 - 1; // Set auto-reload value for 1Hz. TIM1->CCR1 = 50; // Set initial comparison value (PWM duty cycle). TIM1->CNT = 0; // Reset the current count. TIM1->CCMR1 |= (0x6UL << TIM_CCMR1_OC1M_Pos ); // Set PWM

Used nucleo-h563zi board.Below is bootloader jump.Below is app. question:I first download app through CubeIde,this code is run success,and every function is OK.But i reset this board,the code will enter NMI interrupt. 

Hello ! [STM32L073RZ]I've been thinking what is this ADC DMA continuous request. I don't really much know what it is exactly and why it must be enabled. I know there are 2 modes of DMA, which is normal and circular in which normal starts only once and stops after sending everything he has, and circular after sending everything he has starts again from the beggining of a buffer. I have here 4 questions regarding to this topic : -> What is this  ADC DMA continuous conversion mode and does it involve in DMA modes ?-> What happens if I have Circular Mode of the DMA and have disabled ADC DMA continuous conversion mode ? -> What happens if I have Singular Mode of the DMA and have enabled ADC DMA continuous conversion mode ? -> In UART in DMA I didn't have this option of DMA continuous

Evaluating the STM32F070RBT6 for a project, and using STM32CubeMX V6.10 I am unable to connect the PLL to the HSI RC. It all works ok if I use HSE.I'm wondering what I'm doing wrong. 

Hi, For our project we have one Bootloader in 0X80000000 and application program in 0X80001c00. We have to combine both of these binary files and load it in to our controller. What is the best way to combine two binaries ? We are using windows platform. 

I want  to run MCU with VDD 1.8V (in order to have all I/O-signals as 1.8V). I changed to use a LQFP64 package which provides a dedicated pin for VDDUSB.I power VDDUSB with 3.3V (for sure not below 2.7V) but all other VDDs on MCU are 1.8V:USB function (FS PHY) FAILS if VDD drops below 1.8VMCU seems to run with VDD a bit below 1.8V, e.g. 1.794V. But USB is not working anymore!For USB I need at least 1.804V: then boot is OK, USB comes up and later VDD can drop to 1.793V and still working (but not booting up properly with USB on 1.793V: no USB enumeration anymore).All my 1.8V ordered and soldered LDOs do not work - because they provide just 1.79xV: USB does not come up.And the debugger (external ST-Link) becomes flaky with VDD a bit below 1.8V (50% of the tries it does not find the target).So,with "off-the-s

Hello, I am using STM32F042K6T7 microcontroller for doing some start-up configuration for some Ethernet PHYs by SMI, it is working well at room temperature, and cold (-40°C), but when I increase temperature max (+74°C) the microcontroller it seems is not able to start-up because the SMI signals (MDIO and MDC) seems not to work, I did some test with a Nucleo-F042K6 which has the STM32F042K6T6 heating up the microcontroller up to +74°C and it seems not having the same issue then I would like to make sure that my understanding is correct.It suppose STM32F042K6T6 has a operating temperature of -40°C to 85°C andSTM32F042K6T7 has an operating

if I configure the USART and use HAL_UART_Transmit. The UART to USB bridge is taken care of by the ST-Link chip.Could i use the VCP on the board is on PA9/PA10(pin D14 and pin D15 to rx and tx to arduino) and use digital.read on arduino to get the information of char[] like tipo "%s %.0f%%"?  

I have configured the M7 clock to 480 MHz and the M4 clock to 240 MHz using the HSI as input.  In SystemClock_Config routine the statement__HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);is crashing the STLINK-V3 with the error messageError in executing 'step' command ...Target is not responding, retrying...I had a breakpoint at that line and activated it with the Step Into (F5). 

 I'm trying to update a transmitter called a wfly et16s. They have downloads on their site to upgrade their radio to expresslrs which is just a newer protocol. I installed the stm32 driver and it shows its working, I can connect to stm32cubeprogrammer through usb to the radio. I cannot however use there upgrade exe file to get a dfu going. When i go through the steps to get the radio into upgrade mode and click the exe file they provide a box appears. The box has a dropdown list of dfus and its blanked out. I'm not sure someone here knows what i should do other that research everything on the internet and contact everyone(which i have) i'm wondering if i can get this exe decompiled and loaded through stm32cube since it connects. I'ts a small file too. http://www.wflysz.com/products_52/208.html?type=%E4%B8%8B%E8%BD%BD or 

Hello,I'm using a STM32U5A5VJTXQ MCU and I need to use the 2K BKPSRAM located @0x40036400.I can read and write without problem the BKPSRAM after power up, but a power cycle corrupt all the content. Strangely, the RTC content: time and registers, are all retained.Do I have to make a special setting to ensure that the BKPSRAM retains its contents?ThanksBest RegardsClemente

Hi,I am at the beginning of my STM32F756VGH6 register programming journey. I have already setup everything, and now I am at the led blink (using a logic analyzer for measuring the time intervals). I decided to make a simple blocking delay function out of a basic timer. The reference manual of STM32F756VGH6 describes the basic timers as really simple and beginner friendly peripheral. I did my best to follow the datasheet and common sense. However, the timer is completely unpredictable right now... Increasing or decreasing the counter prescaler results in some 1.5x or 2.3x incremental steps (prescalers can only by round numbers.) I am not sure is my timer 6 primarily fed with 50 MHz or 100 MHz, because APB1 clock have 2 derivatives, one dedicated only to timer peripherals, so I was going out to find it out by experimenting with the delay value. However, giving the delay function variable of only "1" results in some 6.167 us delay, which is orders of magnitu

Hello,I've got a setup where I put the STM32 into STOP mode, with wake-up on ADDR match on I2C.SYSCLK is PLL 32 MHz.APB = 32MHz.I've configured I2C to use HSI, and enabled STOP_WUCK.(The I2C uses DMA).If I enable HSI16KERON then the device responds as normal to back-to-back I2C transactions. i.e. if I want to access registers A, B, C. (Write followed by read) This is fine. However when this is disabled it seems to only be able to respond to one transaction (i.e. A is fine, B and C are missed). Is this expected behavior? If I put a delay of about 20us it also seems to resolve the problem.

Hi, i need to build a system that has two physical USB ports:- USB-Host: Type-A USB2.0 HID device to connect an external Midi-controller- USB-Device: Type-C USB2.0 or USB3.x to act as a multi-channel audio sound card, and also HID device (MIDI controller) at the same time- Fast CPU to perform audio DSP, STM32H7 with 480 or 550MHz would be fine.- Micro SD card connectorI can not find a way to setup an STM32H7 in CubeMX to have two physical USB ports, as there is only one USB_OTG_HS peripheral available. Did i overlook something here?  I prefer programming in C/C++ on the bare metal CPU and not using RTOS or embedded Linux. I was thinking of using an STM32MP135DAGx instead of the STM32H7 and program it bare metal, but this would require to interface an external FLASH and maybe also a DDR RAM, which i have never done before. I suppose at least a FLASH is necessary?Looking forward to any suggestions :)

Posted on June 15, 2015 at 12:57 Hello I am a beginner in using STM32 devices, so please tell me if I am doing something incredibly wrong here. I am trying to enable DMA for SPI on STM21F411RE but I keep getting TEIF error on the SPI3 channel for DMA1 Stream 5. Here is DMA initialization code: /*******************************************************************************************************************/ // DMA for SPI3: DMA1, Channel 0, Stream 5 DMA1->HIFCR = 0xffff; DMA1->LIFCR = 0xffff; // clear interrupt flags for all streams RCC->AHB1ENR |= RCC_AHB1ENR_DMA1EN; // Enable clock for DMA1 DMA1_Stream5->NDTR = 1; // One data item per transfer (1 byte) DMA1_Stream5->PAR = (uint32_t) &SPI3->DR; // Peripheral address register (address of SPI3 DR) // FIFO disabled (direct mode) SPI3->CR2 |= SPI_CR2_TXDMAEN; // Enable DMA for SPI NVIC_EnableIRQ(DMA1_Stream5_IRQn); // Enable DMA interrupt for the stream DMA1_Stream5->CR

Hello everyone, as port of my role I am looking form SDIO comprehensive course. Can be either online or not. If any of the members can give a recommendation on how to ramp up well on SDIO protocol / use cases / specs / etc. it will be of great help. Thanks in advance

  When I was using Cube MX software to generate LWIP examples for STM32F107, using RAW mode was very normal. But once FREERTOS  lwip is selected through CUBEMX, basic PING communication cannot be achieved. I am wondering if there is anything to pay attention to in the generated software, but I have been unable to find it. I really need help. Thank you. Here is my CUBEMX configuration diagram, and I hope you can point it out to me. I am using STM32F107VC dp83848  

Hi.I'm looking for some answer which I can not find anywere.What is the time between instruction execution time consisting of writing '1' to GPIO->BSRR of any pin and port and real mcu pin state in case when HCLK is e.g. 72MHz and APB2 is 4,5MHz (APB2 prescaler is 16).(F1  series is just example) 

As i state in the title, what is the best way to detect a connection to a console app on a pc?I want to include a while loop in my program, that stalls the main program until the user establishes a connection and the program proccedes to the super loop.Is there a function or a variable that detects the conection and returns true or false respectively ?SHould i try to create a handshake between the two ?
