This is a list of open-source hardware projects, including computer systems and components, cameras, radio, telephony, science education, machines and tools, robotics, renewable energy, home automation, medical and biotech, automotive, prototyping, test equipment, and musical instruments.
An embedded system on a plug-in card with processor, memory, power supply, and external interfaces. An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.
Virtually all embedded systems have a hardware element and a software element, which are separate but tightly interdependent. The ICE allows the software element to be run and tested on the hardware on which it is to run, but still allows programmer conveniences to help isolate faulty code, such as source-level debugging (which shows a program as it was originally written) and single-stepping ...
Apple M1 system on a chip A system on a chip from Broadcom in a Raspberry Pi. A system on a chip or system-on-chip (SoC / ˌ ˈ ɛ s oʊ s iː /; pl. SoCs / ˌ ˈ ɛ s oʊ s iː z /) is an integrated circuit that integrates most or all components of a computer or electronic system.
Hardware emulation – Use of special purpose hardware to emulate the logic of a proposed design. Can sometimes be plugged into a system in place of a yet-to-be-built chip; this is called in-circuit emulation. Technology CAD simulate and analyze the underlying process technology. Electrical properties of devices are derived directly from device ...
Hardware-in-the-loop (HIL) simulation, also known by various acronyms such as HiL, HITL, and HWIL, is a technique that is used in the development and testing of complex real-time embedded systems. HIL simulation provides an effective testing platform by adding the complexity of the process-actuator system, known as a plant , to the test platform.
Additionally, open-source hardware organizations such as OpenCores are collecting free IP cores, paralleling the open-source software movement in hardware design. Soft macros are often process-independent (i.e. they can be fabricated on a wide range of manufacturing processes and different manufacturers).
A typical hardware setup using two shift registers to form an inter-chip circular buffer. To begin communication, the SPI master first selects a slave device by pulling its SS low. (Note: the bar above SS indicates it is an active low signal, so a low voltage means "selected", while a high voltage means "not selected")
