Internal Interrupts are used to respond to asynchronous requests from a certain part of themicrocontroller that needs to be serviced. Each peripheral in the TriCore as well as theBus Control Unit, the Debug Unit, the Peripheral Control Processor (PCP) and the CPUitself can generate an Interrupt Request.So what is an external Interrupt?An external Interrupt is something alike as the internal Interrupt. The difference is that anexternal Interrupt request is caused by an external event. Normally this would be a pulseon Port0 or Port1, but it can be even a signal from the input buffer of the SSC, indicatingthat a service is requested.The User’s Manual does not explain this aspect in detail so this ApNote will explain themost common form of an external Interrupt request. This ApNote will show that there is aneasy way to react on a pulse on Port0 or Port1 and to create with this impulse an InterruptService Request. Later in the second part of the document, you can find hints on how todebounce impulses to enable the use of a simple switch as the input device.Note: You will find additional information on how to setup the Interrupt System in theApNote “First steps through the TriCore Interrupt System” (AP3222xx)1. It would gobeyond the scope of this document to explain this here, but you will find selfexplanatoryexamples later on.
Base64 demonstrates how easy it is to decipher
plaintext usernames and passwords. Never login to a public network resource
unless some type of encryption is being used, secure socket layer is one example.
Most FTP sites also use plaintext passwords.
aPLib is a 32-bit compression library based on the compression algorithm
used in aPACK (my executable packer). aPLib is an easy-to-use alternative
to many of the heavy-weight compression libraries available.
A graphics toolkit, Graf_Tool() is developed which can be used
to process and edit graphics. Labels, lines and arrows can be
added and the program is very flexible and easy to use.
HTML Parser is a Java library used to parse HTML in either a linear or nested fashion. Primarily used for transformation or extraction, it features filters, visitors, custom tags and easy to use JavaBeans. It is a fast, robust and well tested package.
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
This is full set of procedures used to communicate with
any GSM module for SMS sending/receiving (it uses standard AT commands).
Original code is for ATMega162 microcontroller, but code is general to
be easy ported to others platforms.
Code can be compiled with IAR AVR compiler.
"Hard to find" full description of ContactID protocol from Ademco used by many home security devices to send messages to CMS (Central Monitoring Station) about security events.
Has full technical description and can be used to easy make CMS communication module that sends info from your alarm system to CMS station.
