Most of devices use GPIOs for controlling LEDs and buttons. There aren't any generic GPIOs numbers, so OpenWrt has to use device specific mappings. It means we need to find out GPIOs for every controllable LED and button on every supported device.

Subject to CPU, scheduler and hardware limitations, can support many PWM outputs, e.g. as many as you have GPIO pins available for. On a 200 MHz ARM9 processor, a PWM frequency of 100 Hz can be attained with this code so long as the duty cycle remains between about 20-80%.

OpenWrt gpio-button-hotplug driver OpenWrt uses a home-grown app called procd as PID1. One of procd 's features is to catch messages from the kernel and act upon them, much in the way a conventional linux system uses a hotplug helper and udev.

LIRC GPIO blaster LIRC is a package that allows you to decode and send infra-red signals of many (but not all) commonly used remote controls. An infrared blaster is a device that emulates an infrared remote control. In this case the task is made using LIRC which will control a GPIO.

chmod +x /usr/sbin/jtag_gpio. And actually the launch itself jtag_gpio (if launch again it turn on JTAG back) … Of course, it turn off JTAG until the next reboot the device, ie, you need to automate the process, for example by writing command in /etc/rc.local.

Wifi is set "automatically" by the calibration data. When using ralink,mtd-eeprom, the driver will expect the mac address at offset 4.With mtd-eeprom reading from 0x0, this will mean that the MAC address is read from 0x4 without having to specify it additionally.
