STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on May 27, 2013 at 13:17Hi, i'm using smt32F303 discovery board, I send / receive data on USART1 without problem if I use interrupt mode, so I think that hardware is good.I want send a data buffer lenght ~ 8000 bytes using dma mode. Before I ...
Posted on May 26, 2013 at 01:34I want to use a Light Dependent Resistor (LDR) to control a door ( open when it feel light and close it when it's darkness).Can you help me how can I do this,I have an STM32F100RB.Thanks a lot
Posted on May 27, 2013 at 13:51 Hello! This is my code for SPI: RCC_APB1PeriphClockCmd(RCC_APB1Periph_SPI2, ENABLE); SPI_InitTypeDef spi; spi.SPI_Direction = SPI_Direction_2Lines_FullDuplex; spi.SPI_Mode = SPI_Mode_Master; spi....
Posted on May 27, 2013 at 02:08Hi all, I need to meassure duration in milliseconds of some process during my program execution. For Arduino the millis() function exists in library but I've found nothing simillar in the STM32 Standard library. How ca...
Posted on May 25, 2013 at 11:00Hello, i have problem with control of simple rotary encoder form Alps (or Piher | Bourns) on STM32. Does anyone have a ready solution. Best regards Andrew #poorly-framed-question #stm32
Posted on May 26, 2013 at 00:35Hi, is it possible to sample GPIOA Bit7-0 into SRAM as byte and to have kind of ''Clk'' nonPWM output on other GPIO , with higher speed than 20MHz on STM32F103 72MHz ? this gives me 10MHz clk output on PC2: Buffer_pt...
Posted on May 25, 2013 at 00:12 Hello! I'm new to micro controller programming. I have been told to ''poll a pin'' and perform a specific action if this pin ''goes low''. So I wrote this code to ''poll'' a PD10 pin on my board: GPI...
Posted on May 20, 2013 at 12:17Hi guys, i use am stm32f0 microcontroller.I've a problem about the ADC channel 13 (PC3 pin) and PA3 pin.when i connect something to PA3 pin seems that the ADC PC3 pin reads the PA3 pin value.this is my ADC configuratio...
Posted on May 25, 2013 at 17:31Hello, I have a program where by after executing TIM4 CCP1 interrupt routine for a specified number of times, I disable TIM4 CCP1 Interrupt and enable TIM4 CCP2 interrupt in TIM1 CCP4 Routine .TIM1 CCP4 ISR check for ...
Posted on May 25, 2013 at 12:42hi 1.)i have a little confusion, if controller can differentiate between system reset and power on reset itself?mean i want to skip few lines of code on system reset but not on power on reset2.) i have a stm32f4 discov...
