wait_ms(2)API
RS485_0.init(1, baudrate=9600, data_bits=8, stop_bits=1, parity=None, ctrl_pin=None)- Initialize UART communication
print(RS485_0.any())- Retain cached data
print(RS485_0.read())- Read all data
print(RS485_0.readline())- Get characters read line by line
print(RS485_0.read(10)) - Read characters
print((str('coils:') + str((RS485_0.read_coils(1, 1, 0)))))- Read coil status
print((str('discrete:') + str((RS485_0.read_discrete_inputs(1, 1, 0)))))- Read discrete inputs
print((str('holding:') + str((RS485_0.read_holding_registers(1, 1, 0, True)))))- Read holding registers
print((str('input:') + str((RS485_0.read_discrete_inputs(1, 1, 0)))))- Read input registers
RS485_0.write('')- Write data
RS485_0.write(''+"\r\n")-Write data line by line
print((str('write multiple coils:') + str((RS485_0.write_multiple_coils(1, 1, 0)))))- Write multiple coils
print((str('write multiple register:') + str((RS485_0.write_multiple_registers(1, 1, 0, True)))))- Write multiple registers
RS485_0.write(bytes([0, 0, 0]))- Write raw data
print((str('write single coil:') + str((RS485_0.write_single_coil(1, 1, 0)))))- Write single coil
print((str('write single register:') + str((RS485_0.write_single_register(1, 1, 0, True)))))- Write single register
