Arduino Mega ATmega2560微控制器的脉宽调制编程 我试图在脉宽调制上启用阿迪诺·梅加(ATmega2560),但我面临一些问题。 首先,我尝试用Ada编写程序。我想在Timer3中使用三个FastPWM频道,所以我写了 代码语言:javascript 运行 AI代码解释 procedure Main is begin--Nullify Timer3 buffersTCCR3A:=0;TCCR3B:=0;TCCR3C...
首先要确定你的Arduino 的哪些引脚支持PWM输出,数字引脚上标记了 ~ 符号的就是支持PWM的。Arduino主控芯片为ATmega168或者ATmega328的3, 5, 6, 9, 10, 和 11引脚支持PWM,Arduino Mega的 2~13 , 44~46引脚支持PWM,老板子ATmega8的9,10,11脚支持PWM。 Arduino的库中通过analogWrite函数来完成PWM输出。 analogWri...
硬件是SparkFun,和ARDUINO MICRO PRO一样(芯片是ATMega32U4),最近想做一个手柄,因为使用ARMega32U4的SparkFun能够模拟串口设备,比如键盘、鼠标或者手柄,所以就用了SparkFun。库的话用的是XInput库,这个库可以让SparkFun作为Xbox手柄被电脑识别,库正常加载了,而且代码也编译正常,上传正常。代码如下: #include <XInput...
The obvious solution to this problem is an Arduino Mega 2560. Oh yeah, this thing is powerful! 54 pins! 4 UARTS! 8k RAM! You add it to your cart, and then realize it’s almost $50. Now maybe you’re wondering, isn’t there anything in-between that might be a bit less cash? In...

I’ve got a breakout board for the Atmega1281,http://www.elecfreaks.com/store/bare-pcb-atmega128-smallest-system-board-p-137.html. The old Adruino Mega was based on the Atmega1280 (which has 100 pins compared to the 64-pin 1281). I had read somewhere that with the latest IDE that ju...

pedalSHIELD MEGA Hardware Design.As an Open Source project, the design was done using KiCad (free/open ECAD tool). All the project files, schematics, and Bill of Materials are public. The circuit can be broken down into 6 simpler blocks: Power Supply, Input Stage, Output Stage, User ...
2– Choose Which Pins to Interrupt I know I said earlier that a change on any of the pins in a port would trigger the port’s ISR, but that is true only when you turn that particular pin on. This is down with what is called a mask. Since the ATMEGA328 has 3 ports, it also ha...
Similarly, if you are using Arduino mega pins 20 and 21 are SDA and SCL respectively. Arduino Digital Clock using DS3231 Pi Module circuit diagram So, connect the SDA or D pin of your RTC module to the SDA pin and the SCL or C pin to the SCL pin of your Arduino board. The Vcc ...
