Pogo pin hardware define

Pins 6, 7, 13, 14 are turned OFF by default. These can be turned on via SDK.

1	GND	Ground PIN	8	UART_RX	1.8V UART RXD
2	GND	Ground PIN	9	UART_TX	1.8V UART TXD
3	GND	Ground PIN	10	GPIO_1	1.8V GPIO 1
4	GND	Ground PIN	11	GPIO_2	1.8V GPIO 2
5	GND	Ground PIN	12	IRQ	1.8V External Interrupt PIN
6	POGO_5V	5V/500mA DC-DC Power OUT (OFF default)	13	POGO_5V	Same to PIN 6
7	POGO_VBAT	VBAT Power OUT (OFF default)	14	POGO_VBAT	Same to PIN 7

Pogo pin path define

The path can be obtained from the system properties. Each pin has a special attribute key, and the corresponding path can be obtained by calling the system attribute tool through reflection.

POGO_5V
System property key: ro.pogo.path.vbus
Default value (if not define): /sys/class/ext_dev/function/ext_dev_5v_enable

POGO_VBAT
System property key: ro.pogo.path.vbat
Default value (if not define): /sys/class/ext_dev/function/ext_dev_3v3_enable

GPIO_1
System property key: ro.pogo.path.gpio1
Default value (if not define): /sys/class/ext_dev/function/pin10_en

GPIO_2
System property key: ro.pogo.path.gpio2
Default value (if not define): /sys/class/ext_dev/function/pin11_en

IRQ
System property key: ro.pogo.path.irq
Default value (if not define): /sys/class/ext_dev/function/irq_state

Serial
System property key: ro.pogo.path.serial
Default value (if not define): /dev/ttyHSL1
