Simple helper to compute sysfs GPIO numbers from PIN names on Pine64

pine64-gpio-number.py

#!/usr/bin/python3

import sys
import string

def convert(value):
	value = value.upper()
	alp = value[1]
	idx = string.ascii_uppercase.index(alp)
	num = int(value[2:], 10)
	res = idx * 32 + num
	return res

if __name__ == "__main__":
	args = sys.argv[1:]
	if not args:
		print("Usage: %s <pin>" % sys.argv[0])
		sys.exit(1)

	print("%d" % convert(args[0]))

Hey, I did this in GO. Thx! ❤️

func convertPIN(p string) (string, error) {
	v := strings.ToUpper(p)
	le := v[1:2]
	li := strings.Index("ABCDEFGHIJKLMNOPQRSTUVWXYZ", le)
	ln := v[2:]
	ai, err := strconv.Atoi(ln)
	if err != nil {
		return "", err
	}
	res := (li * 32) + ai
	return strconv.Itoa(res), nil
}
