Here’s a class I created to communicate via Python. With Python code just use the Arduino serial communication libraries to receive and send the data.
In the class you have the method to send a data list and to receive a data list. Now just set your communication protocol as: buffer size, header, checksum according to your need!
import serial
class Comunicacao():
def SerialInit(self, NomePorta, Velocidade, TimeRX, TimeTX):
try:
self.PortaCom = serial.Serial(NomePorta, Velocidade, 8, serial.PARITY_NONE, serial.STOPBITS_ONE, TimeRX,
False, False, False, TimeTX)
self.PortaCom.reset_input_buffer()
self.PortaCom.reset_output_buffer()
except Exception:
print("Erro na porta " + NomePorta + "!")
def WriteSerial(self, DadosTx):
try:
self.PortaCom.flushOutput()
TamPac = DadosTx[3]
for i in range(TamPac):
DadoTxByte = bytes((DadosTx[i],))
self.PortaCom.write(DadoTxByte)
print(DadoTxByte)
except Exception:
print("Erro Escrita")
def Leitura_Serial(self, DadosRx):
LeituraSerial = [0] * 200
for i in range(200):
if (self.PortaCom.in_waiting > 0):
LeituraSerial[i] = self.PortaCom.read()
LeituraSerial[i] = self.ByteToInt(LeituraSerial[i])
print(LeituraSerial[i])
else:
break
DadosTx = [1,2,3,4,5,6,7,8]
DadosRx = [0] * 100
PortaCom = Comunicacao()
PortaCom.SerialInit("/dev/ttyUSB0", 115200, 1, 1)
PortaCom.WriteSerial(DadosRx)
worked out, thank you very much !!!

Can you put the code in the question? Pyserial works well with Arduino.
