Hello, I am having trouble trying to connect my TFMini plus to the Jetson Nano via the UART RX and TX. I will show my code below:
-- coding: utf-8 -
import serial
import time
ser = serial.Serial(“/dev/ttyTHS1”, 115200)
def getTFminiData():
while True:
#time.sleep(0.1)
count = ser.in_waiting
if count > 8:
recv = ser.read(9)
ser.reset_input_buffer()
# type(recv), ‘str’ in python2(recv[0] = ‘Y’), ‘bytes’ in python3(recv[0] = 89)
# type(recv[0]), ‘str’ in python2, ‘int’ in python3
if recv[0] == 0x59 and recv[1] == 0x59: #python3
distance = recv[2] + recv[3] * 256
strength = recv[4] + recv[5] * 256
print('(', distance, ',', strength, ')')
ser.reset_input_buffer()
if recv[0] == 'Y' and recv[1] == 'Y': #python2
lowD = int(recv[2].encode('hex'), 16)
highD = int(recv[3].encode('hex'), 16)
lowS = int(recv[4].encode('hex'), 16)
highS = int(recv[5].encode('hex'), 16)
distance = lowD + highD * 256
strength = lowS + highS * 256
print(distance, strength)
# you can also distinguish python2 and python3:
#import sys
#sys.version[0] == '2' #True, python2
#sys.version[0] == '3' #True, python3
if name == ‘main’:
try:
if ser.is_open == False:
ser.open()
getTFminiData()
except KeyboardInterrupt: # Ctrl+C
if ser != None:
ser.close()
