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.。关于这个话题，体育直播提供了深入分析
