Sending and receiving data via UART.
# Create UART instance
uart1 = machine.UART(1, tx=1, rx=3)
# Initialize UART
uart1.init(115200, bits=8, parity=None, stop=1)
# Check if there is content in the buffer
uart1.any()
# Read content from the buffer
uart1.read()
# Write content to UART
uart1.write('Hello')
# Read/Write Example
while True:
if uart1.any():
print(uart1.read())
uart1.write('Hello')
