SCPI is easy to use. Designing a complete programmable instrument around it is not.
SCPI from the Ground Up: Instrument Control, Embedded Systems, and Platform Management takes the reader beyond command syntax to show how modern programmable instruments are actually designed.
Starting with the foundations of SCPI and IEEE 488.2, the book follows commands through the complete instrument architecture-from communication interfaces and parsing to execution engines, device drivers, FPGA logic, DMA, high-speed data paths, synchronization, and hardware control.
It also addresses the engineering problems that appear when an instrument grows beyond a simple bench device: modular hardware, dynamic discovery, multi-channel acquisition, platform management, environmental monitoring, watchdogs, remote operation, security, firmware updates, and system health.
Practical examples show how these concepts come together in real systems, including a minimal SCPI instrument, a modular PCIe instrument, a high-speed multi-channel ADC system, and an RF switching system.
Topics include:
SCPI command structure, parsing, status, and error handlingIEEE 488.2 common commands and instrument stateUSB, Ethernet, VISA, PCIe, and other communication architecturesControl paths versus high-speed data pathsEmbedded processors, FPGAs, registers, interrupts, and DMAMulti-channel and multi-module synchronizationDevice drivers and hardware abstractionCalibration and configuration persistencePlatform management, thermal monitoring, power, and watchdogsNetwork services, REST interfaces, and remote instrumentsSecurity and defensive SCPI parsingFirmware updates and lifecycle managementPractical implementation patterns and engineering lessonsRather than treating SCPI as an isolated protocol, this book places it where it belongs: as the control interface to a complete instrument system.
Written for embedded software developers, FPGA engineers, test engineers, hardware designers, driver developers, and system architects, SCPI from the Ground Up provides a practical bridge between the command sent by the user and the hardware that ultimately performs the measurement.
