arduino是否适合高频应用? [英] Is arduino suitable for high frequency application?

问题描述

我可以将arduino用于频率为4 MHz的应用程序吗?

Can I use the arduino for an application with a frequency of 4 MHz?

我需要创建一个具有此频率的clk，并在上升沿和下降沿发送和接收数据.而且它不是普通的SPI接口，我有自己的条件，所以我需要手动进行操作.

I need to create a clk with this frequency and send and receive data on the rising and falling edges. and it is not a normal SPI interface I have my own conditions so I need to do it manually.

如果不合适，在技术上可行吗?

If it is not suitable, is it technically possible?

推荐答案

使用arduino Mega 2560可以产生的最大PWM是62500 Hz.我认为您无法超越.方法

The maximum PWM you could generate with an arduino Mega 2560 is 62500 Hz. I don't think you can go beyond that. Method

您可以使用内部SPI，因此对于16MHz振荡器，您的最高频率可能在16MHz至(16/128)MHz之间.方法

You can use the internal SPI so with a 16MHz oscillator you could have upto some where from 16MHz to (16/128)MHz. Method
