I followed the help document to operate pb, compiled the system and prepared to run the system with the simulator. However, when attaching the device, a command line window popped up, showing the simu...
Comparing the two voltage regulators, both are linear regulators, and the AMS1117 can output a maximum current of 1A, while the HK7833 can only output a maximum current of 500ma, but the price is 10 t...
iMEMS semiconductor technology integrates micro-mechanical structures and electronic circuits on the same chip. iMEMS accelerometers use this technology to measure single-axis, dual-axis, or even tri-...
Preface:
The usage of the NAND FLASH version and the eMMC version of the core board are basically the same. This article mainly describes the U-Boot compilation, basic device tree file compilation, NA...
As a natural human-machine interface, voice can make the in-vehicle navigation system safer and more user-friendly. Through the functional comparison of domestic and foreign in-vehicle navigation s...[Details]
The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]
In the field of software development, the most critical but also the most unpredictable phase is the debugging phase. There are many factors that play a role in the process of software debugging, a...[Details]
