w1-ds18b20

This app allows reading ds18b20 sensors in bitbang mode using direct GPIO memory access. Currently supports only HiSilicon-style GPIO offsets. Pull-up resistor is required.

Usage

Example: reading temperature using GPIO8_2 on Gk7205V300 (consult datasheet or ipctool output)

# ./w1-ds18b20 -base 0x120B8000 -gpio 2
