GPIO numbers for Weigand

[surfmk]

Hi,

I am finding the documentation for GPIO numbers a bit confusing.

Am I correct :

   

HT1 = GPIO1
HT2 = GPIO2
HT3 = GPIO3

Am I correct :

   

P39 = GPIO39
P40 = GPIO40
P41 = GPIO41

Finally, Can any of these pins be assigned for TX/RX for D0/D1 with Weigand Protocol?

Hopefully, this will allow me to configure my entry alarm system.

Many thanks in advance.

Paul

sure, it's ok for wiegand.

Thank you for your kind response... but I still need an answer please:

Please can you comment about the GPIO numbers - actually I am just guessing.

HT1 = GPIO1
HT2 = GPIO2
HT3 = GPIO3

P39 = GPIO39
P40 = GPIO40
P41 = GPIO41

1. Are these GPIO correct ?
2. Can any of these GPIO be assigned for TX/RX for D0/D1 ?
3. To help other customers, please can you provide GPIO numbering documentation for KC868-A16v3 ?

Thank you,

Paul

Can anyone help answer the questions ?
Many thanks

1-wire (pull-up resistance on PCB):
1-wire1:GPIO47
1-wire2:GPIO48
1-wire3:GPIO38

free GPIOs (without pull-up resistance on PCB):
free gpio-1:GPIO39
free gpio-2:GPIO40

all esp32 pin define at here: https://www.kincony.com/forum/showthread.php?tid=7614
free gpio-3:GPIO41

I would like to know what the best GPIO for Weigand... 

now I understand the location and PGIO numbering

Thanks.

showed in your RED section. just GPIO-1, GPIO-2, GPIO-3.
GPIO-1=GPIO47
GPIO-2=GPIO48
GPIO-3=GPIO38

This makes sense now...

ESPhome has code:

Code:

- platform: gpio
    name: "A16v3 IO47"
    pin:
      number: 47
      inverted: true

  - platform: gpio
    name: "A16v3 IO48"
    pin:
      number: 48
      inverted: true

  - platform: gpio
    name: "A16v3 IO38"
    pin:
      number: 38
      inverted: true

  - platform: gpio
    name: "A16v3 IO39"
    pin:
      number: 39
      inverted: true

  - platform: gpio
    name: "A16v3 IO40"
    pin:
      number: 40
      inverted: true

  - platform: gpio
    name: "A16v3 IO41"
    pin:
      number: 41
      inverted: true

So, for Weigand we use

Code:

wiegand:
  - id: mykeypad
    d0: GPIO47
    d1: GPIO48
    on_key:
      - lambda: ESP_LOGI("KEY", "received key %d", x);
    on_tag:
      - lambda: ESP_LOGI("TAG", "received tag %s", x.c_str());
    on_raw:
      - lambda: ESP_LOGI("RAW", "received raw %d bits, value %llx", bits, value);

d0: GPIO47
d1: GPIO48

Can you advise this is the best solution for Weigand communication?

Thanks, 

Paul

you can config wiegand by ESPHome, we also will update new KCS v3 firmware to support wiegand.

Hi

I am a beginner with wiegand and ESPHome. I understand how to install wiegand ESPHome - this looks quite easy.

Please can you advise: If I install wiegand ESPHome ... do I still need the firmware upgrade for KC868-A16v3 ??

When will the latest KCS v3 firmware support wiegand please?

Maybe the KCS v3 firmware to support wiegand is only required for non-ESPHome applications?

Thanks,

Paul
