1939 Parameter Group
A Parameter Group (PG) in J1939 is the same concept as a CAN frame. PG is the exchange of information from ECUs to ECUs in a J1939 protocol network. PG […]
J1939 Protocol Principal Features
SAE J1939 network communication is developed for harsh use environments and can be used for the horizontally integrated vehicle industry. J1939 is also applicable for “off-road” or “on-road” vehicles, light, […]
J1939 Protocol
CAN Introduction CAN is based on a “broadcast” communication mechanism. This broadcast communication is based on a message-oriented transmission protocol. These messages are identified by Ids. A CAN ID has […]
Embedded Systems: Race Conditions
When the system is capable of sharing resources by threads or interruptions, race conditions is an extremely difficult source of bugs, therefore race conditions shall be avoided. Race conditions produce […]
Embedded Systems: ISR
ISR stands for Interruption Service Routine. ISR can be represented by function(s) that acknowledge and dispatch the interruption that the system detects. The normal use case of ISRs is as […]
Embedded Systems: Preemption
Some developers call Preemption to the ability of a processor to interrupt a task (or interrupt) when a higher interrupt occurs. If a low priority task is not to be […]
