Two PWM outputs from MCU combine to form a monotonic 16-bits DAC

How do you generate complementary PWM Outputs? I would like to generate complementary PWM Outputs with adjustable dead time. According to the STM32F401RE Microcontroller datasheet http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1577/LN1810/PF258797,

DMA部分我用到的相对简单,当然,可能这是新东西,我暂时还用不到它的复杂功能吧.下面用问答的形式表达我的思路. DMA有什么用? 直接存储器存取用来提供在外设和存储器之间或者存储器和存储器之间的高速数据传输.无须CPU的干预,通过DMA数据可以快速地移动.这就节省了CPU的资源来做其他操作. 有多少个DMA资源? 有两个DMA控制器,DMA1有7个通道,DMA2有5个通道. 数据从什么地方送到什么地方? 外设到SRAM(I2C/UART等获取数据并送入SRAM): SRAM的两个区域之间: 外设

Using SPI to read a Barometric Pressure Sensor This example shows how to use the SPI (Serial Peripheral Interface) Communications Library to read data from a SCP1000 Barometric Pressure sensor. Please click here for more information on SPI. Hardware

An Isolated DAC Using PWM Output Arduino‘s (ATmega328P) PWM outputs via analogWrite can be conveniently turned into analog voltage levels through the use of simple RC filters. Since the PWM outputs are not isolated, using them to drive other devices

Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required analog signals. You can use PWM signals to create bot

1. Requirements To generate a PWM output, we need to create a train of pulses with constant period and variable duty cycle. The duty cycle, being the modulation is the pulse width. Typically, a timer is used to maintain both the period and duty cycle

http://www.cs.indiana.edu/~geobrown/book.pdf An example of a basic timer is illustrated in Figure 10.1. This timer has four components – a controller, a prescaler (PSC), an “auto-reload” register (ARR) and a counter (CNT). The function of the prescal

how to generate an analog output from a in-built pwm of Atmega 32AVR microcontrloller? you need a resistor, a capacitor and an opamp. opamp is not really necessary when you are driving a mosfet, but will make life a bit easier. just be aware, that th
