Pins to cc1101

[Gnitset]

Found your blog post about this that is very old. See that you have kept the repo uptodate.
I'm a bit confused though over how to connect the cc1101.

I have the 8pin version that should have the following pinout (according to a quick google image search):
Pin 1 = GND
Pin 2 = VDD
Pin 3 = GDO0
Pin 4 = CSN/SS
Pin 5 = SCLK
Pin 6 = MOSI
Pin 7 = MISO/GD01
Pin 8 = GDO2

spi:
  clk_pin: GPIO18
  mosi_pin: GPIO23
  miso_pin: GPIO19

cc1101:
  id: cc
  cs_pin: GPIO5
  frequency: 433.42MHz

cover:
  - platform: somfy
...
    cc1101: cc
    pin:
      number: GPIO13

I have connected:
cc1101 - esp32
pin1 - gnd
pin2- 3.3v
pin3 - D13
pin4 - D5
pin5 - D18
pin6 - D23
pin7 - D19
pin8 - D12

the logs say:

...
[D][spi_device:393]: mode 0, data_rate 1000kHz
[D][cc1101:122]: CC1101 found! Chip ID: 0x0014
[C][component:208]: Setup cc1101 took 13ms
...

Where is gdo2/gpio12 used/configured?

When pressing the button that runs id(...)->program(); nothing seems to happen.

What am I missing? Maybe an updated blog post or some more examples in the repo?

GDO2 is not connected/configured, as we don't use the cc1101 for receiving anything. GDO0 is sufficient.

IDK, I removed GDO2 and moved GDO0 from GPIO13 to GPIO17 (to have all the pins on the same side).
Now it works. Thank you.

Would you be open to a pull request that adds some more information?

Absolutely
