NAME PINE64::GPIO - Perl interface to PineA64 and PineA64+ GPIO pins SYNOPSIS use PINE64::GPIO; #instantiate PINE64::GPIO object my $p64 = PINE64::GPIO->new(); #export pin 25 (physical pin 40) for output $p64->gpio_enable(25, 'out'); #continuously blink LED for(;;){ $p64->gpio_write(25, 1); sleep(1); $p64->gpio_write(25, 0); sleep(1); }#end for DESCRIPTION This module manipulates the GPIO file system interface of the PineA64 and PineA64+ single board computers so you can control the GPIO pins on the PineA64's PI-2 bus. The PineA64's 40-pin PI-2 bus has the same pinout as the Raspberry Pi's 40-pin GPIO, however this module has it's own GPIO pin numbering convention for the 26 GPIO pins as follows: Module# Physical# A64 sys# ------------------------------------------ 0 3 227 1 5 226 2 7 362 3 11 71 4 13 233 5 15 76 6 19 64 7 21 65 8 23 66 9 29 229 10 31 230 11 33 69 12 35 73 13 37 80 14 8 32 15 10 33 16 12 72 17 16 77 18 18 78 19 22 79 20 24 67 21 26 231 22 32 68 23 36 70 24 38 74 25 40 75 METHODS new() Returns a new C object. gpio_enable($pin, 'out') Takes the GPIO pin number and direction as arguments and exports it for use as either an input or output. Valid pin number arguments are 0-15, and the direction is either 'in' or 'out'. $p64->gpio_enable(25, 'out'); gpio_read($pin) Takes pin number as an argument and returns the logic value on the pin. gpio_write($pin, $value) Takes pin number and value as an argument and writes the value to the GPIO pin. Valid values are 0 or 1. gpio_disable($pin) Takes pin number as an argument and unexports the pin in the file system interface.
