I'm writing code for the STM32F411 and STM32F103 MCUs using the ST HAL library. The firmware reads an IDR directly using the HAL function HAL_GPIO_Read_Pin. The function is called 2 to 3 times in main(), that is, the IDR register is 'polled' more tha...
In my application I need to design a multi purpose digital input which can operate in 3 modesON/OFF detectionFrequency measurement andPulse CountingI can do the last 2 using HW Timers in Input Capture mode and configuring it for both edges. In the al...
In this Tutorial, TM1637 LED driver is interfaced using STM32 microcontroller. The steps of building the interface from scratch and the used hardware are explained in details.Tutorial video:https://youtu.be/hrVOO_k5FOIAll codes and documents are shar...
In Standby mode it is given like this.... (1.2 V domain powered off).All 1.2 V domain clocks OFFwhat does this means?
Right now, I am able to get I2C data from sensor. I have generated PWM signal separately with TIM_CH2. But I have no idea how to generate pwm from I2C signal. So, basically I need to control amplitude of pwm from i2c signal. I am using NUCLEO-L011K4 ...
Hello,I don't find on the STM32H730ZB datasheet a clear information about the maximum current output for the DAC ( with or without a OPAMP in follower). I plan to drive a LED from 100µA to 10mA maximum.Today, I have an externaI op-amp & mosfet but I ...
I'm trying to get a STM32Cube project compiled using arm-none-eabi-gcc and a Makefile. The FW builds without problems.but when I boot the MCU i get stuck in Hard Fault. Any ideas what could be wrong?Reset_Handler: ldr sp, =_estack /* set s...
Hello everybody,I'm using STM32CubeIDE version v1.7.0 and Firmware package FW_H7 v1.9.0. The tests were made on a Nucleo H745ZI (dual-core MCU).Test 1:Enabled RTC for the M7Configured RTC Wakeup parametersEnabled RTC Wakeup interrupt on NVICResult: T...
There is a similar open issue in another post. https://community.st.com/s/question/0D53W00000EndiI/stm32g030-adc-issueMy MCU STM32F446 is set to read 9 channels' value by ADC1 with DMA2_Stream4. Settings are as below. Using StdDriver @version V1.8....
