2016-11-24 Introduction Developing mobile handheld devices with touch screen human-machine interfaces is a complex design challenge, especially for projected capacitive touch screen designs, which represent the mainstream technology for current multi-touch interfaces. Projected capacitive touch screens can accurately locate the position of a finger touching the screen by measuring the minute changes in capacitance to … Read more
Introduction I previously envisioned a mobile storage device based on the ESP32, and now I am attempting to create a prototype. The first step, I believe, is to design a dedicated PCB. I previously used an ESP32S3 development board to test how to run WebDAV, but the flash memory on the development board only has … Read more
This course series uses the RK3588 chip as the core basis for hardware design, based on the latest version of Cadence Allegro Allegro X software, to conduct a complete flow of design and simulation for system on-chip resources, interface circuit design, and various commonly used peripheral resources for chip expansion. The latest software features and … Read more
Today, I have compiled some prices of commonly used software tools in embedded development, and some netizens exclaimed: The cost of embedded development is too high! Let me ask everyone first: Do you think the cost of embedded development is high? The answer: Yes! For ordinary people, it is indeed high, except for some wealthy … Read more
I got a car board from a friend, and the main appearance is as follows. Car controllers usually use metal housings to shield strong interference, allowing the system to operate more stably. Today, we will mainly dissect this board to see what functional parts it has. Opening the lower part of the housing, the back … Read more
PCB Design Considerations for RK3588 VDD_LOGIC Power Supply 1. The copper width for VDD_LOGIC must meet the current requirements of the chip. The copper connected to the chip’s power pins should be sufficiently wide, and the path should not be too severely interrupted by vias. It is essential to calculate the effective line width and … Read more
Recently, I watched a detailed explanation of circuit design by Philip Salmony, a graduate student from Cambridge University, on YouTube. The project is called the STM32-based RF to USB adapter, abbreviated as STRF, which includes: High-speed USB interface STM32L4 as the controller nRF24 2.4GHz RF transceiver Of course, he designed it using KiCad, and his … Read more
The Allwinner A64 64-bit processor, released in early 2015, features a quad-core Cortex-A53 architecture and a Mali400MP2 GPU. It supports H.265 4K video hardware decoding and runs Android 5.1. Primarily targeted at entry-level tablets, the A64 was designed for the 64-bit tablet market, but who buys tablets these days? Even my old iPad mini 2 … Read more
