Re: adding a timeout to wifi connexion

i added this to the connection routine

Code: Select all

    while station.isconnected() == False:
        presentTime = time.ticks_ms()
        duration = presentTime - startTime
        if duration > 5000:
            break
        pass
Works like a charm.

Re: adding a timeout to wifi connexion

That look like the way it's behaving.
I'll try that, thank you.

adding a timeout to wifi connexion

Hy, I'm using the sample from the documentation to connect my esp32 boards. def connect(): import network from utils.conf import ip, subnet, gateway, dns, ssid, password station = network.WLAN(network.STA_IF) if station.isconnected() == True: print("Already connected") return station.active(True) st...

Re: shift register bit shifting considerations

OMG, I'm so sorry... I found that it's a hardware issue. When i fix the board in it's case i squashed some soldering and made a short circuit. So the issue was also happening on the reset animation but so fast the untrained eye couldn't detect it. I feel bad for wasting your time but with no idea wh...

Re: shift register bit shifting considerations

Yes, this code is trash, But before optimizing it I wanted to know why it isn't consistent on the different devices and shift registers I have. How come reset_race and update_led always work and turn all leds on and off, but the idle_led doesn't always work but if it fails it's always on the same le...

Re: shift register bit shifting considerations

I would prefer to keep the code as is as much as possible. My question really is on why the random output for the same function ?
Should i upload a new firmware ??

shift register bit shifting considerations [SOLVED]

Hello, I have these two functions that i use on different esp32 board with two SN74HC595N shift registers. def idle_led(i, data, clock, latch): global globalinterrupt_counter global total_interrupts_counter global reset_counter_val global led_count zeros = 16- i print(zeros) for e in range(zeros): c...

Re: external interrupts consideration

Hy Peter, i have used the 3.3v outputs and added a 330ohm resistor to avoid any damage. I'm using the heltec lorawan V2 board https://heltec.org/project/wifi-lora-32/ the pin out diagram https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/PinoutDiagram/WIFI_LoRa_32_V2.pdf So using two AD...

external interrupts consideration

Hy, I was trying to add a second external interrupt to my code. I thought it might help me get out of the while loop. So tried to duplicate the way the first external interupt worked So i added And i had to comment the machine.disable_irq() and enable machine.enable_irq(state) or i had this terrible...
