In this article you are going to learn how to set up and program your Pico with MicroPython. This makes it a great choice for beginners who want to design their own devices but don’t have the patience or interest to learn low-level programming. While most microcontrollers can only be programmed in C or C++, the Pico also offers support for MicroPython, a slimmed down version of Python that is designed specifically for small devices. Unlike the Raspberry Pi, which functions as a general purpose computer and runs the popular Linux operating system, the Pico is a much more primitive device that lacks a central operating system and can only be programmed to perform specific tasks or control connected peripherals, usually as part of an embedded system or Internet of Things device. The standard ADC range is 0-3.3V.With the release of the Raspberry Pi Pico, the Raspberry Pi Foundation has expanded its product offering beyond their highly successful line of mini-computers and went even smaller by entering the microcontroller market. The input signal for ADC0, ADC1, ADC2 andĪDC3 can be connected with GP26, GP27, GP28, GP29 respectively (On Pico board, RP2040 has five ADC channels in total, four of which are 12-bit SAR basedĪDCs: GP26, GP27, GP28 and GP29. deinit () # turn off PWM of slice 0, stopping channels A and B ADC (analog to digital conversion) ¶ duty_u16 ( 0 ) # stop the output at channel A print ( pwm0 ) # show the properties of the PWM object. duty_u16 ( 200 ) # set the duty cycle of channel A, range 0-65535 pwm0. duty_u16 () # get the current duty cycle of channel A, range 0-65535 pwm0. freq ( 1000 ) # set/change the frequency of slice 0 pwm0. freq () # get the current frequency of slice 0 pwm0.
