ADCWiPy 类 – 模数转换
笔记

此类是 WiPy 的非标准 ADC 实现。它可以像 machine.ADC在 WiPy 上一样简单地使用,但在下面的文档中命名,machine.ADCWiPy以将其与更通用的 machine.ADC类区分开来。


# z) V; Z* S/ y& R

用法:

  1. import machine
    4 r, b9 o9 s( C9 l$ x* f

  2. 2 O- I# N/ D- o3 r! S; g  b
  3. adc = machine.ADC()             # create an ADC object
    ) [1 T3 j" g. n% B
  4. apin = adc.channel(pin='GP3')   # create an analog pin on GP3
    0 ~  P8 D$ H+ d6 Y7 Y: _: t/ Y
  5. val = apin()                    # read an analog value
复制代码

# f0 E, d- x# `) y1 F" N! B) z5 `5 Y% k& O; S$ ]# r+ i2 Y% e
  I7 h4 y0 G5 I; x( i% L$ j9 p, t
构造函数classmachine.ADCWiPy(id=0, *, bits=12)

创建与给定引脚关联的 ADC 对象。这允许您随后读取该引脚上的模拟值。有关更多信息,请查看 引脚排列和备用功能表。

警告

ADC 引脚输入范围为 0-1.4V(1.8V 是它可以承受的绝对最大值)。当 GP2、GP3、GP4 或 GP5 重新映射到 ADC 模块时,1.8 V 是最大值。如果这些引脚用于数字模式,则允许的最大输入电压为 3.6V。


5 Z$ o7 {6 ^( x: s, D9 [  {

& t, w$ _8 U- `" t$ }' J( B1 u方法ADCWiPy.channel(id, *, pin)

创建一个模拟引脚。如果仅给出通道 ID,则将选择正确的引脚。或者,只能通过引脚并选择正确的通道。例子:

  1. # all of these are equivalent and enable ADC channel 1 on GP3
    2 n* ~/ M- d: K% m( i2 e$ y6 Q/ d& w
  2. apin = adc.channel(1)8 ?- t6 s2 T4 _' a8 ?
  3. apin = adc.channel(pin='GP3')
    3 o6 M4 V% C/ w' x* ^
  4. apin = adc.channel(id=1, pin='GP3')
复制代码
- @& F# p7 H; Y
& a9 D8 B5 |4 x" z

- f2 o  D9 N7 P5 g7 hADCWiPy.init()

启用 ADC 模块。

ADCWiPy.deinit()

禁用 ADC 模块。


$ |3 O: r4 G5 X$ d7 g- [# q

- E) R8 j3 M2 F- ~" J7 y类 ADCChannel — 从内部或外部源读取模拟值

ADC 通道可以连接到 MCU 的内部点或 GPIO 引脚。ADC 通道是使用 ADC.channel 方法创建的。

machine.adcchannel()

读取通道值的快速方法。

adcchannel.value()

读取通道值。

adcchannel.init()

重新初始化(并有效启用)ADC 通道。

adcchannel.deinit()

禁用 ADC 通道。

I got to know it through a friend of mine, of course good things have to be shared, this store supports multiple payment channels. There are many NBA series jerseys in it, and the retro NBA jerseys are also retained. There are also star jerseys inside, such as: James jerseys, Kobe jerseys, Curry jerseys, etc. Don't miss the free shipping event for orders over 99€!
