# 初始化UART1和UART2
uart_A = UART(UART.UART1, 115200, 8, 0, 0, timeout=1000, read_buf_len=4096)
uart_B = UART(UART.UART2, 115200, 8, 0, 0, timeout=1000, read_buf_len=4096)

# 测试串口收发
write_bytes = b'hello world'
for i in range(20):
    uart_A.write(write_bytes)
    time.sleep_ms(1)
    if uart_B.any():
        read_data = uart_B.read()
        if read_data:
            print("write_bytes = ", write_bytes)
            print("read_data = ", read_data)
            if read_data == write_bytes:
                print("baudrate:115200 bits:8 parity:0 stop:0 ---check Successfully")

uart_A.deinit()
uart_B.deinit()
del uart_A
del uart_B
