kevinmcaleer / easy_comms Goto Github PK

i flashed the picoA file in one rasberry pico and the picoB on the other one and in both picos i flashed the easy_comms file . I don't understand why it doesn't work , it is the same code. I also run one pico from one pc and the othr pico with another pc . or should i run it both picos in the same pc ?

• The output of pico_comms_a :

     ahoy
  
     sending message: ahoy
  

• the output of pico_comms_b :

    ahoy
  
    sending message: ahoy
    sending message: helloA,0
  

I want to know the max speed this program can go from pico to pico.

It does it if you don't received anything, you should do this to fix it, I did it in my version.

def read(self)->str:
start_time = time_ns()
current_time = start_time
new_line = False
message = ""
while (not new_line) or (current_time <= (start_time + self.timeout)):
current_time = time_ns()
if (current_time > (start_time + self.timeout)):
new_line = True

        if (self.uart.any() > 0):
            message = message + self.uart.read().decode('utf-8')
            if '\n' in message:
                new_line = True
                message = message.strip('\n')
                # print(f'received message: {message}')
                return message
    else:
        return None
