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')
