Large LED array with reduced data management
An LED controller system includes an LED controller including an image frame buffer able to receive image data. A sensor processing module is used to receive and process sensor data and a decision module is used to determine actions taken in response to processed sensor data. An image creation module is used to create images to be sent to the image frame buffer of the LED controller.

an LED controller including an image frame buffer able to receive image data;
a standby image buffer coupled to the image frame buffer to hold default image data of a default image;
a sensor processing module to receive and process sensor data to create processed sensor data; and
a decision module to:
make a determination as to whether the processed sensor data is available; and
select, dependent on the determination whether the processed sensor data is available, among use of the processed sensor data and the default image data to be used for image creation; and
an image creation module to create images to be sent to the image frame buffer of the LED controller based on the determination.

9. The LED controller system of claim 1 , wherein:
the LED controller is used for vehicle headlamps, and
the sensor data including data selected from ambient light level, time of day, vehicle location, location of other vehicles, road conditions, and weather conditions.
10. The LED controller system of claim 1 , wherein the decision module is configured to select as the default image data an initial pattern on vehicle start.
11. The LED controller system of claim 1 , wherein the determination to use the default image data is provided to the LED controller through a Controller Area Network (CAN) bus and the determination to use the processed sensor data is provided to the LED controller through a local bus.
12. The LED controller system of claim 1 , wherein the LED controller is configured to control sensors that provide the sensor data.
13. A method of interacting with an LED controller system, comprising:
receiving image data using an LED controller including an image frame buffer;
holding default image data of a default image in a standby image buffer coupled to the image frame buffer;
making a determination as to whether sensor data has been received and processed to form processed sensor data, and the processed sensor data is available;
selecting, dependent on the determination whether the processed sensor data is available, among use of the processed sensor data and the default image data to be used for image creation; and
creating images with an image creation module, the images being sent to the image frame buffer of the LED controller based on the determination.
