Practical Application of ESP32 Arduino Development Environment: From GPIO to Web Server
Published2026.10.13 15:41This white paper, based on the presentation slides and technical Q&A from the e4ds-hosted webinar "Completing Your Own IoT System with ESP32," explains five fundamental hands-on exercises for working with ESP32 on the Arduino platform (GPIO input/output, serial debug, UART communication, Bluetooth SPP, Wi-Fi web server) from a design decision perspective. Each exercise is organized around causality—identifying what problem prompted it, what was chosen, and what was sacrificed—and boundary conditions that must be verified during the productization phase, such as power consumption, electrical protection, security, and OTA, are explicitly stated based on technical Q&A.

MIPI CSI-2, DSI-2, C-PHY, D-PHY Test Solution Technical White Paper
The MIPI interface adopts a burst mode that transitions between low-power (LP) and high-speed (HS) states for low-power consumption, and in return, strict timing rules are imposed on state transitions. Additionally, the high-speed section operates as a packet-based protocol with headers, ECC, and CRC, so verification engineers must handle waveforms and protocols simultaneously. Traditional configurations combining general-purpose oscilloscopes and AWGs reveal limitations in setup complexity, measurement uncertainty, and lack of reproducibility when faced with these requirements. This white paper, based on webinar materials, organizes the structure of this problem and describes how the SV5C-DPTXCPTX generator for receiver testing and SV5C-DPRXCPRX analyzer for transmitter testing integrate state transition testing, stressed eye testing, and protocol analysis into a single bench, along with their application boundaries.

DDR/LPDDR Protocol Analyzer Technical Whitepaper: Non-Invasive Observation of Live Memory Links
This whitepaper addresses the live memory link observation solution composed of Introspect Technology's DDR/LPDDR protocol analyzer (M7030), remote sampling head (RSH, multi-channel active probe), and integrated tip interposer. Based on maximum 36-channel aligned capture and 80 Gsps asynchronous sampling, automatic command and timing verification based on JEDEC specifications, and field measurements of probing in non-terminated mode LPDDR5X 8533 MT/s systems, this document describes the causality and trade-offs of each design decision and their application boundaries. All figures are based on webinar presentation slides and technical Q&A; items that were not cross-verified have been excluded from the main text and separately organized as review items.

War on Noise: Piercing Through SI/PI/EMI in the Frequency Domain
In high-speed digital design, SI, PI, and EMI are not separate issues but a single physical phenomenon sharing Vias, PDN, coupling, and return paths. Based on WaveInSense webinar materials, this white paper organizes the causal chain of frequency domain analysis—from transmission line theory through Via Stub resonance, PDN anti-resonance, to a three-element model of system-level EMI. Finally, through an ultrasonic equipment EMC certification case study, it demonstrates how minimal changes targeting root cause structures led to certification acquisition and cost reduction (external chamber monthly usage reduced to 1/18 compared to the highest user).

Advanced Capacitive Sensing Technology for Moisture-Resistant Touch and Digital Level Sensing
Capacitive sensing is replacing mechanical buttons and contact-type water level sensors by virtue of its non-contact and movable-part-free characteristics. However, water and frequently changing ground conditions directly disturb its measurement principle. Based on Microchip webinar materials, this white paper describes the principles, configuration, and performance basis of Digital Level Sensing (DLS), which reports water level regardless of ground conditions, and Impulse Touch Sensing (ITS), which eliminates the effect of water at the moment of signal acquisition. Furthermore, it specifies application boundaries that designers should be aware of, including recommended mechanical stack-up below 5mm, inapplicability to metal containers, and the necessity of validation for media other than water.

Practical HIL Construction Strategy for Automotive and Off-Highway Controller Validation
As vehicle E/E architecture transitions to zonal structures and shifts to software-defined vehicles (SDV), the number of controllers (ECUs) requiring validation and software complexity are surging dramatically. Meanwhile, real vehicle testing cannot provide repeated verification under identical conditions and entails lead time and safety concerns. This white paper explains the principles of HIL (Hardware-in-the-Loop) validation and the structure of the NI platform composed of PXI, SLSC, and VeriStand, and through two actual implementation cases—Camera Record & Replay HIL for In-Cabin Monitoring Controller (ICMU) and Forklift Controller (VCU) HILS—describes how controller-level regression testing becomes possible. Additionally, it explicitly states application boundaries and limitations, such as lack of A2B support.
