I’ve been working on MicroPython for ESP32 recently and working on implementing some of the crazier hardware on the device.. Capacitive touch sensor controllers are widely available, but having the facility built in making the ESP32 competitive with cheaper SoCs which don’t already include these facilities.

7. Pulse Width Modulation¶ Pulse width modulation (PWM) is a way to get an artificial analog output on a digital pin. It achieves this by rapidly toggling the pin from low to high. There are two parameters associated with this: the frequency of the toggling, and the duty cycle.

It can be change to 160MHz if you need more processing power, at the expense of current consumption: >>> machine. freq (160000000) >>> machine. freq 160000000 MicroPython comes with a library specific to the pyboard (pyb) as well as generic libraries that are supposed to work with any supported board (eg. machine), and their functions sometimes overlap. I had to consult the MicroPython forum a few times to figure out the best approach.

MicroPython’s Timer class defines a baseline operation of executing a callback with a given period (or once after some delay), and allow specific boards to define more non-standard behavior (which thus won’t be portable to other boards). See discussion of important constraints on Timer callbacks. microPython的函数很多. machine module. CPU主频 import machine machine.freq() # 获得当前CPU频率 machine.freq(160000000) # 设置当前CPU频率 ...

Program the 'Hello World' of hardware with MicroPython. To blink the LED we'll connect to the MicroPython board's REPL (read-eval-print loop, like a Python 'command prompt') and run commands that control the digital GPIO connected to the LED. .

In Micropython you need to define either a hardware address or the Pins. I could not find any information about the hardware address of the I2C chip. Therefore I initialized I2C like this: import machine i2c = machine.I2C(sda=machine.Pin(21), scl=machine.Pin(22), freq=400000) # Now scan the bus: i2c.scan() Battery Monitoring MicroPython Newsletter – Subscribe to the MicroPython newsletter for news and announcements including new features and new products.
