1. Overview of the Porting Process Hardware Platform Setup Selection of the main control chip: It is recommended to use the STM32F4 series (such as STM32F407) or Microchip SAMD5x series, which must support SPI/SQI or HBI interfaces to communicate with LAN9253. Hardware connection: LAN9253 connects to the main control via the SPI interface, requiring configuration … Read more
This article will detail how to write a .NET IoT device driver from scratch using the NV3030B LCD device driver as an example. We will use the Raspberry Pi as the hardware platform and refer to the official .NET IoT Ili934x TFT LCD driver library. 1. Background In the previous article “Getting Started with .NET … Read more
What is Java SPI Java SPI (Service Provider Interface) is a service provider interface that is a service discovery and loading mechanism provided by Java, allowing developers to define multiple implementations for an interface and dynamically discover and load these implementations at runtime. The core of the Java SPI mechanism is that it provides a … Read more
When a microcontroller or FPGA sends SPI control signals to a phase-locked loop (PLL) chip, it often requires a series connection of a 22 ohm or 33 ohm resistor. What is the reasoning behind this? Impedance discontinuities can cause electromagnetic wave reflections, which in turn can lead to signal distortion. Therefore, impedance matching is often … Read more
The following diagram shows the SPI standard mold polishing grade table, from which the polishing grades A~D in the mold industry originate. The A-grade claimed by 3D mold manufacturers also comes from here. There are four columns: ~ The first column is the grade code ~ The second column is the abrasive, tool, and polishing … Read more
Click the aboveblue text to follow us In embedded systems, the Serial Peripheral Interface (SPI) and its extensions (such as DSPI and QSPI) are widely used for high-speed communication with external devices (such as sensors, memory, LCD controllers, etc.). The main differences are as follows: 1 SPI SPI (Serial Peripheral Interface) is a full-duplex synchronous … Read more
