Lucas De Marchi	47f25a0aa0	AP_HAL_Linux: remove _export_pins() method ... The initial idea was to export all pins to be used at once, so we created _export_pins() to take all of them and a wrapper method, _export_pin() to export a single one. However we never export more than one pin at once.	9 years ago
José Roberto de Souza	0c0d595b55	AP_HAL_Linux: Export GPIO pin inside of pinMode() ... Make sure pinMode() method exports the pin before using it. Otherwise the export method would need to be called, differently from other GPIO implementations. Since now export_pin and export_pins are called only internally, reduce their visibility to protected.	9 years ago
Gustavo Jose de Sousa	cdf70f6fe5	AP_HAL_Linux: add GPIO_Sysfs ... This commit adds the class Linux::GPIO_Sysfs. This class provides a generic implementation of AP_HAL::GPIO on Linux by using GPIO Sysfs Interface (https://www.kernel.org/doc/Documentation/gpio/sysfs.txt). The channel() interface should be preferred in places that need to be fast. Since it maintains the file descriptor open this is much faster than opening and closing it.	10 years ago
