| This property is used to preconfigure the GPIOs and connect them to |
| a primary(0) or a secondary(1) pin. EOS S3 supports up to 8 GPIOs |
| which can be configured as follows |
| "GPIO_NUM : primary_pin_num / secondary_pin_num" |
| "0 : 6 / 24" |
| "1 : 9 / 26" |
| "2 : 11 / 28" |
| "3 : 14 / 30" |
| "4 : 18 / 31" |
| "5 : 21 / 36" |
| "6 : 22 / 38" |
| "7 : 23 / 45" |
| E.g. configuring GPIO 2 as secondary results in controlling pin 28, |
| to do so set the bit on the 2nd index of this property |
| "pin-secondary-config = <0x04>;" |
