Tiny 2350 - RGB LED PWM Pico SDK

Same thing, same approach for direct comparison of different platforms, only in MicroPython this time…

import time, machine

ACTIVE_LOW_RGB = True

TINY2350_LED_R = machine.PWM(machine.Pin(18))
TINY2350_LED_R.freq(1000)
TINY2350_LED_B = machine.PWM(machine.Pin(19))
TINY2350_LED_B.freq(1000)
TINY2350_LED_G = machine.PWM(machine.Pin(20))
TINY2350_LED_G.freq(1000)

def pwm_set_rgb(red, blue, green):
  if(ACTIVE_LOW_RGB):
    red = 255-red; green = 255-green; blue = 255-blue
  TINY2350_LED_R.duty_u16(int((red * 65535) / 255))
  TINY2350_LED_B.duty_u16(int((blue * 65535) / 255))
  TINY2350_LED_G.duty_u16(int((green * 65535) / 255))

while True:
  pwm_set_rgb(255, 0, 0)
  time.sleep(0.5)
  pwm_set_rgb(0, 255, 0)
  time.sleep(0.5)
  pwm_set_rgb(0, 0, 255)
  time.sleep(0.5)

Thanks! Noob here: I can confirm this code runs on a Tiny2350 (flashed earlier with MicroPython), this code being saved onto it, and run from Thonny. The LED blinks in alternating 3 colors: red, blue, and green

Note: I installed Thonny from python’s uv.
