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......
Hi, I am new to stm32 I am not getting how to read the values what I write to the 24c16 EEPROM IC .Plz help me how to read the values by generating the read function in stm32 f103.void write_eeprom_reg(uint16_t reg_addr, uint8_t value){ //uint8_t d[...
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 ...
Hi, i am new to stm32 i need to write negative values (signed integers or float) in my modbus and transmit it to my PC. But i am not able to write negative values it shows some other values if i transmit negative values . can anyone help me w...
Dear ST,I am coming back to you to configure a PWM peripheral with STM32F429.I am familiar with TI DSP and I have to implement it with ST this time.Could you help me to configure TIMER1 for symmetrical PWM and trigger an interrupt to trig ADC. I ma u...
