来自：https://forum.micropython.org/viewtopic.php?t=9829&p=55021#p55021 从arduino库中移植，使用两个GPIO，一个作为触摸输入，另一个使用1兆欧电阻连接到输入，通过充电时间判断触摸状态。 # touchA.py by CWE from machine import * from utime import * led= Pin(25, Pin.OUT) led.value(0) send= Pin(16, Pin.OUT) # via 1meg resistor connected to touch pad send.val...

不过发现了一个奇怪的问题，在PICO上每次的计算时间会增加，而在其它开发板上不会。

对前一版程序做了修改，使用不同字符代表不同颜色（发散速度），效果更好一些。 from time import ticks_ms, ticks_diff MAX_ITER = 60 MANDEL_CHAR = (     ' ', '.', '`', ',', ':', ';', '|', 'o', '<', '>',     '(', ')', '{', '}', '+', '~', '=', '-', '#', '@' ) def run(func, param = None):     t1 = ticks_ms()     if param == None:         func()...

将micropython源码中的examples/mandel.py例子修改了一下，用于测试计算性能 from time import ticks_ms, ticks_diff def run(func, param = None): t1 = ticks_ms() if param == None: func() else: func(param) t2 = ticks_ms() print('calc time:', ticks_diff(t2, t1), 'ms') def mandelbrot(): # returns True if c, complex, is in the Man...
