Arduino Due 是一块基于 Atmel SAM3X8E CPU的微控制器板.它是第一块基于 32位ARM核心的arduino. 它有54个数字IO口 (其中12个可用于PWM输出),12个模拟输入口,4路UART硬件串口, 84 MHz的时钟频率, 一个USB OTG接口, 两路DAC(模数转换),两路TWI,一个电源插座,一个SPI接口,一个JTAG接口,一个复位按键和一...
In this tutorial we are going to adjust the brightness of an LED, by using PWM signal generated by DUE. A DUE PWM (Pulse Width Modulation) signal provides a variable voltage over constant power supply.

The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects. When we need to go small, we use a Metro Mini or a Trinket M0, but when size isn't as much of a concern, we reach for an Adafruit METRO. ...
IT之家 3 月 6 日消息，Arduino 家族又添新成员，其新推出的 GIGA R1 WiFi 开发板基于双核 Arm 架构 MCU，外形与现有 Mega 和 Due 相同，尺寸仅 101 x 53 mm，提供 76 个 GPIO 引脚，而且支持无线网络。这是 Arduino 迄今为止最强的开发板，售 72.82 美元（IT之家备注：当前约 503 元人民币）。这款...
我们目前正在使用 ADS1299并使用 SPI 接口与 Arduino Due 进行通信。 除了 CONFIG1寄存器中写入0x94h (对应于1K SPS)之外、每个寄存器都设置为默认值。 器件设置为 RDATAC 模式、当 DRDY 变为低电平且 CS 设置为高电平时接收字节。 然而、即使最低采样率为250SPS、我们每...
有个神奇的地方,ESP的芯片有专门控制LED的外设,又因为控制LED就是控制的PWM,舵机的控制也是PWM,所以很自然的就会想到用LED的外设去控制舵机。 可以参考官方的文档 LED 控制 (LEDC) 外设主要用于控制 LED 的强度,但也可用于生成 PWM 信号以用于其他目的。它有 16 个通道,可以生成独立的波形,例如用于驱动 RGB LED...
I connected a small LED to pin 11 to see the results of the above PWM code sample. As expected, it operates at a reduced brightness due to the lower voltage. The ‘127’ is a number that can range from 0 to 255, with 255 being the brightest setting. You can use this to set the...
