Ask questions, find answers, and share insights on STM32 products and their technical features.
The technical docs state that multipleication (MULS instruction) can take either 1 cycle or 32 cycles. This is defined when the board is produced. Does anyone know which of the two configurations the STM32F072RB uses?
Hi,When operating in single 32bit filter mode, is it possible to use this additional space to check the first byte of the message data/payload when dealing with standard frames?I have an issue with a particular ID "spamming" every 500ms or so and am ...
that's it.. say i have 4 channels (PA0 , pA1 , PA2 , pA3)..what i need is : in the while(1) loop i put 4 variables, and keep reading the data registers , and because it's in continous mode, so the 4 variables keep updating in the backgroud, how can ...
Hi to all, i want to know where we can download :AN5428 :system memory RSS servicesThanks
Hi,I am trying to put my STM32 part in sleep mode.I have attached the code here.As per my understanding to go into sleep mode HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);API is provided.even though I used below lines, my board...
The STM32F401's VDD is 3.3V.The I2S Codec's VDD is 1.8V.We will add the Level chip(TXB0104) on The device driving the data I/Os of the TXB0104 device must have drive strength of at least ±2 mA.Does the STM32F401RB's I2S port drive current more than 2...
This is my source code for the SPI configuration:static void SPI1_init(){ //GPIOs konfigurieren //PA4 Chip select //PA5 clk //PA6 MISO //PA7 MOSI uint8_t ch; while(SPI1->SR & SPI_SR_FTLVL); // Wait until no more data to transmit while...
I am using one timer (timer2) as pwm generator and i am using 3 channels on it. I wish to set each channel pulse width independently (they are controlling LEDs) from 1 to 100. But from the generated stcubeIDE function, it looks like that the channels...
So I've got some very basic code for a STM32 to read an encoder using timer 1 in encoder mode.This first routine works fine counting up and down as expected, printing CW (Clockwise) while counting up and CCW (Counter Clockwise) while counting down......
Here is my process :I supply my board with an USB cable.Then I flash my stm32L4 with a segger / st-link.My firmware goes in shutdown mode.I unplug the USB cable. Thus the power is suddently off.After that, I wire a battery to my device. Thus the MCU ...
