I am a beginner. This summer, the teacher taught us the basics of 51 single-chip microcomputers. I used Keil and PROTUS , and learned about 8*8 dot matrix and 1062 LCD screen, etc. Because I have neve...
In 2011, I will give away a series of video tutorials: I want to give them to those who are active in embedded boards, those who participate in various DIY activities, those who have a strong interest...
The LSM6DSO32 iNEMO inertial module is a system-in-package (SiP) that integrates a 3D digital accelerometer and a 3D digital gyroscope in a single compact, low-power chip. The LSM6DSO32 has best-in-cl...
