What is EEPROM?

The EEPROM is an inert memory chip that can be erased and changed. It is used to store a variety of things, including the serial numbers and other unique information in virtually everything connected to Ethernet as well as the chip that is used in printers, charge cards, and even blood glucose monitors. It is able to store information that controls microcontrollers' operation as well as a method to recover from power-on reset scenarios.

The basic EEPROM chip contains two field effect transistors. One of them is a floating gate, and the other is a control gate. When the device is powered up the electrons are released. They are trapped in a 0 or a 1 state depending on the voltage applied. The EEPROM can be read by determining the state of these transistors.

If the EEPROM state is «0» and it is «0», it has no value. If the EEPROM state is «1» it has a 1 value. In between these two states, no data is stored, but it can still be written. EEPROMs can be erased by a short time of voltage applied to the gate.

The benefit of EEPROM is that it can be erased and written to without any external circuitry. This makes it very useful in systems where the memory is required to be updated regularly for example, remote keyless microcontrollers in systems. There are other kinds of memory chips that offer similar functions, but are better suited for long-term storage.

Modern flash memory chips, for instance, are very popular and are found in computers and digital cameras. These are often used to store multimedia files to be used for short-term as well as long-term storage and retrieval. But, they are not true EEPROMs and their core functions differ from those of true EEPROMs. However, EEPROMs continue be extensively used due to their versatility, and their ability to store minimal quantities of data in a restricted space.

What is OBDII?

Up until recently, most automobile manufacturers had their own diagnostic systems for diagnosing issues with their vehicles. In 1996, the government ordered that all cars utilize a standard system for reading diagnostic codes. This new system, known as OBD-II is based on the same port and diagnostic code system for all models and makes of automobiles that are sold in the US. This means that if there is an issue with your vehicle it will be simple for any mechanic to figure out what the issue is by plugging in a special tool.

The system is then able to identify and repair any faults before causing significant damage. Technicians are able to connect to the OBD-II port using a scanner tool, which displays all error codes and show the part of the system they originated from.

Scan tools have a greater computing power than code readers and can detect more types of error codes. They also display live data graphs, and record data that can be later analyzed. Some tools are capable performing complex tasks, such as reprogramming an ECU or offering performance-enhancing options. These high-end tools are usually employed by professionals in the field of automotive mechanics and are more expensive than basic code scanners.

When connecting a scanner to the OBD II port, it will recognize the protocol it is using and communicate with the vehicle using the correct pins. There are a variety of protocols. The most popular are SAE J1850 (KWP2000) that is used by Ford and some GM automobiles, ISO 14230-4, used in various European and Asian vehicles, and CAN.

The key is embedded with a transponder chip which transmits the coded signal. This is transmitted via an antenna coil (loop) at the ignition lock.

CasSystem implements the logic of CAS state. This class should be created on every instrument which needs to receive data. Making multiple instances of this class can cause undesirable behavior. CasSystem also manages alert messages, in addition to providing state data. To do so it generates a ca_activate_alert topic that requires event information in the form of an object that has the key and priority properties. The topic contains the ID and, optionally, the suffix of the alert you'd like to activate, as well as its priority level.
