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...
HiI need to use RFID with an stm32f4 controller. By using RC522 library it is not working for me can anyone tell that is there is any library available for it or is i have change anything RC522 library.
I am putting board into STOP mode for saving power. From the manuals the board can be woken up from STOP by EXTI interrupt. Is it possible to waking it up by UART by configuring it as EXTI interrupt on Rx pin. If yes how can I achieve this?
I'm using an STM32F466RE to drive a motor via PWM and want to sample a current monitor via ADC during the active part of the pulse so that I can integrate the amount of power delivered to the motor. This will require the sample rate to be high enoug...
I don't use libraries.I got I2S working by polling. Below was my test. I had an array of 16 bit signed words for a tone of 1khz. The I2S pins from the MCU feed a an external DAC and produces a very nice tone. RCC->APB1ENR |= RCC_APB1ENR_SPI3EN...
I am collecting a stream of ADC samples that are being integrated (added together and multiplied by the time period) at regular intervals during an ISR but was hoping there may be a way to offload this so I could just read and reset the accumulated v...
Went through examples of Nucleo -L073RZ eval board for PWM outputIt generates four PWM waves using Timer 2 channel 1 ,channel2 ,channel 3,channel 4at 50%,25%,12.5.37.5% duty cycle . So the pwm duty cycle is fixed.but i have a fan pwm connected to T...

I am trying to use asynchronous USART on stm32L4R5ZI nucleo board for sending and receiving data. Following is related part of code.while (1) { HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin); //Toggle LED HAL_Delay(1000); //Delay 1 Seconds for(...
Need to verify a STM32 firmware for DSP use. Message me for more details.
