C++ (Cpp) epdc_disable_pins Examples

Example #1

File: mx6sabresd.c Project: heyoufei2/yocto_uboot2015

void epdc_power_off(void)
{
	/* Set PMIC Wakeup to low - disable Display power */
	gpio_set_value(IMX_GPIO_NR(3, 20), 0);

	/* Disable VCOM */
	gpio_set_value(IMX_GPIO_NR(3, 17), 0);

	epdc_disable_pins();

	/* Set EPD_PWR_CTL0 to low - disable EINK_VDD (3.15) */
	gpio_set_value(IMX_GPIO_NR(2, 20), 0);
}

Example #2
