Re: [ts-7000] DIO Subroutine for TS-7200

[Matthieu Crapet <>]

Hi,

Since 2.6.27 you can use sysfs entries for GPIOs:

# echo 8  >/sys/class/gpio/export  // DIO_0 = Port B, bit 0
# echo 9  >/sys/class/gpio/export  // DIO_1 = Port B, bit 1
# echo 10 >/sys/class/gpio/export  // DIO_2 = Port B, bit 2
# echo 11 >/sys/class/gpio/export  // DIO_3 = Port B, bit 3
# echo 12 >/sys/class/gpio/export  // DIO_4 = Port B, bit 4
# echo 13 >/sys/class/gpio/export  // DIO_5 = Port B, bit 5
# echo 14 >/sys/class/gpio/export  // DIO_6 = Port B, bit 6 (could have been 
reserved for I2C)
# echo 15 >/sys/class/gpio/export  // DIO_7 = Port B, bit 7 (could have been 
reserved for I2C)
# echo 17 >/sys/class/gpio/export  // DIO_8 = Port F, bit 1

For example:

# echo "out" >/sys/class/gpio/gpio8/direction 
# echo "1" >/sys/class/gpio/gpio8/value
