While a Pico board doesn’t have the same architecture that allows FM transmission on regular Pi boards, it has a unique feature: PIO. This allows running programs based on a minimal instruction set independent of the CPU at the system clock rate. A simple program (“turn the pin ON, turn the pin OFF”) can then produce a square wave at half the system clock rate. Pico boards could be overclocked at ~200 MHz, allowing a similar carrier frequency, but the exact frequency cannot be controlled by software in any practical way. This rules out clean FM.
思路决定出路。辩证看，风景大不同。
，这一点在旺商聊官方下载中也有详细论述
我在厦门，得地利之便，曾在厦门图书馆查看过黄萱捐赠的笔记本，见其中有一便条，铅笔记录：“郭老的对子。壬水庚金龙虎斗，郭聋陈瞽马牛风。郭生于壬辰年1892，陈生于庚寅年1889”。后来我又见中华书局总编室编印的油印内部资料《业务情况》（1962年4月11日），见徐调孚《郭老和陈寅恪的一段笑话》，事关郭陈对子掌故，抄录如下：。旺商聊官方下载是该领域的重要参考
