Led Driver Samples

All we need to do is create a timer and set it to fire one second from 'now'. You’ll be auto redirected in 1 second. Now we will make the LED blink with a given period (1 second in this example). All form fields are required.

In this example we will use the GPIO_GEN1 signal that corresponds to pin 12 on P1 and GPIO18: According to the BCM2835 peripheral description, the GPIO pins can be controlled by The user-mode applications will be able to modify the period via a sysfs interface. You can step through the initialization to re-check everything: Connect to your Raspberry Pi over SSH and write the new period value to the /sys/class/LedBlink/LedBlink/period file:You will see how the LED Learn more Competitor cross-reference Search for any suppliers' LED drivers to find similar TI devices by parameter.

However if we do that in our init() function, we will lock up the kernel and prevent other modules from being loaded until init() returns.

Note that the Raspberry Pi kernel already comes with a GPIO driver that allows user-mode applications to control the GPIO pins (and LEDs connected to them) directly, however we will not If we were writing a user-mode application, we could just make an infinite loop with a call to sleep() inside it.

This is accomplished in 3 steps: Register a device class (e.g. /sys/class/LedBlink) Register a device object within the class (e.g. /sys/class/LedBlink/LedBlink) Create a sysfs file for the device object (e.g. /sys/class/LedBlink/LedBlink/period) Build your module and start debugging it.

You can step through the initialization function to double-check that all necessary initialization suceeds: Once you hit F5 to resume the Raspberry Pi kernel the LED will start blinking: Now we TI offers simple indicator drivers and RGB controllers with on-chip memory for pattern generation. First of all, create a basic kernel module project for Raspberry Pi by following this tutorial.
