This is the badly obfuscated code I'm trying to work with. All I need to do is to get fields 7 and 8 of the $sgynmrc record. I'm fighting this %$%$ piece of code all the way. I don't know how the author had the face to put this up on github.

Check = ord(data[1])
for i in range(2, len(data)):
Check = Check ^ ord(data[i])
data = data + Temp[16]
data = data + Temp[int(Check/16)]
data = data + Temp[int(Check%16)]
self.config.Uart_SendString(data.encode())
self.config.Uart_SendByte('\r'.encode())
self.config.Uart_SendByte('\n'.encode())
print (data)
#print ("def L76X_Send_Command(self, data):")
def L76X_Gat_GNRMC(self):
data = self.config.Uart_ReceiveString(BUFFSIZE)
print (data)
print("def L76X_Gat_GNRMC(self):")
print ('\n')
