Analog input, analog output, serial output Reads an analog input pin, maps the result to a range from 0 to 255 and uses the result to set the pulsewidth modulation (PWM) of an output pin. Also prints the results to the serial monitor. The circuit: * potentiometer connected to analog pi...

OUT指令:将OSR寄存器移出指定位数到指定寄存器中,空位补零。bitcount决定了移出多少位,Destination决定要移出到哪里,可以是output pin或者X,Y等。 如果Destination是EXEC寄存器则下一步将立即执行移到EXEC中的指令。如果设定了OSR自动pull,则移出指令到EXEC后,OSR将从TXFIFO中自动拉取下一个数据,搭配DMA应当可以实现自动...
