Thermostat Project using DS18B20 and P89V51RD2 Microcontroller. Compiler USED is SDCC. Schematic Included. Main file is "09.C". The code is written for turning the relay on and off at particular temperature thresholds.
Program for implementing AES on 8051 based microcontrollers. SDCC is USED as the C compiler. Microcontroller USED is P89V51RD2. There are 2 programs included. One program will accept string via UART and accept key via a 4x4 keypad and display decrypted text on 16x2 LCD. The other program will accept plaintext from UART and show encrypted text on 16x2 LCD after receiving key from 4x4 membrane keypad. Schematics and screenshots are included.
This application note describes the three methods that can be USED to
program the Flash code memory of the 89C51Rx+/Rx2/66x families
of microcontrollers. It discusses in detail the operation of the
In-System Programming (ISP) capability which allows these
microcontrollers to be programmed while mounted in the end product.
These microcontrollers also have an In-Application Programming
(IAP) capability which allows them to be programmed under firmware
control of the embedded application. This capability is also described
The attached zip includes a c code for initializing ILI9322 display chip USED in many 3.5 TFT LCD devices. this is a SPI based initialization code in C which can be seamlessly ported to any architecture. I have also added the datasheet for easy reference
Very good Java Applet USED to animate Inserting, Deleting and Searching (Preorder & Postorder algorithm) nodes in Binary Trees. This is a part of mine students project.
You can use and redistribute the source code absolutelly free!
