LILYGO, a well-known manufacturer of ESP32-S3 boards, has introduced its latest product, the LILYGO T-HMI board. This board is based on the ESP32-S3 and features a 2.78-inch color display with resistive touch technology, making it an excellent choice for HMI (Human Machine Interfaces)...

Undoubtedly, the ESP32 has become one of the most popular development platforms over the years. That is why the developer's community has used this microcontroller to build many cool boards like UNIT DualMCU, Banana Pi Centi, M5Stack CoreS3, Seeed Studio XIAO, and many more. But what...

Converting Digital Data To Analog Signals In the previous parts of the article, we considered how to convert an analog signal to digital by PCM method, as a binary encoding process. Now we want to consider the reverse process as binary decoding. This combination of binary...

Bus Transceiver A Transceiver is a device allowing a bidirectional interface between buses for either digital or analog signal communication and has input & output control capability. It uses back-to-back Tri-state buffers for the communication of multiple devices over a common data...

SparkFun introduces RTK Reference Station, a hardware device for high-precision geolocation, surveying, and time reference. The platform leverages Real Time Kinematics (RTK) to deliver improved positional accuracy. It combines signals from Global Navigation Satellite Systems (GNSS) with...

Renesas has recently announced that they will be introducing their first MCU on the new 22nm node. This MCU will be an expansion of the RA 32-bit Arm Cortex-M family and will be specifically designed for wireless applications. It will incorporate software-defined radio and provide...

Introduction In the first part of this article, we considered the two main stages of a PCM (Pulse Code Modulation) system as the widespread A/D (Analog to Digital Conversion) method and we saw how a continuous signal can be sampled in time and then quantized to limited integer levels in...
