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>;"
