Summary
Graphics displays are widely used in many applications and
the number of products with displays is steadily growing. A
primary reason is that a Graphical User Interface (GUI) can
greatly simplify the use of a device. The GUI can interface a
display with a variety of input devices, such as keyboards,
touch screens or mice. Keyboards range from devices with
several side buttons to those enabling text entry. Low cost
and the ability to quickly enter data result in frequent use of
keyboards.
Summary
Currently, there are three data encryption standards
approved for use in the Federal Information Processing
Standards (FIPS). This application note discusses the
implementation of two of these for PIC24, dsPIC30/33 and
PIC32 devices: Triple Data Encryption Standard (TDES) and
Advanced Encryption Standard (AES). Source code for this
application note (Part Number SW300052) is available from
Microchip for a nominal fee.
*AES and T-DES data rate represents the average of the data rates for performing basic
