How to use

LED

R: PA0 G: PA1 B: PA2

import time

R = pyb.LED(1)
G = pyb.LED(2)
B = pyb.LED(3)

G.toggle()
B.toggle()
time.sleep(1)
G.toggle()
B.toggle()

Switch

Key: PC13

sw = pyb.Switch()
sw.value()  # returns True or False
sw.callback(lambda: pyb.LED(3).toggle())

I2C

I2C1: SCL(PB6) SDA(PB7)
I2C2: SCL(PB10) SDA(PB9)
I2C3: SCL(PA8) SDA(PB8)

i2c = machine.I2C(1)
# i2c = I2C(scl='PB3', sda='PB5', freq=480000)
i2c.scan()

i2c.writeto(0x60, '<123>')
i2c.readfrom(0x60, 5)

i2c.readfrom_mem(0x60, 0x10, 7)
i2c.writeto_mem(0x60, 0x10, 'licsber')

UART

UART1: TX(PA9) RX(PA10)
UART2: TX(PA2) RX(PA3)
UART6: TX(PA11) RX(PA12) # Not allowed, used by USB.

u1 = pyb.UART(1, 115200)
u1.write('Hello\nLicsber!')
u1.readline()
u1.readline()
