Submitted by Curious Bin, thank you~ Recently, while learning about the Raspberry Pi, I encountered a problem when driving the OLED screen, which was display issues. After two days of troubleshooting, I discovered that the driver chip for this OLED is not SSD1306 but SH1106. Therefore, using the Adafruit_Python_SSD1306 library results in display issues. There … Read more
Let’s talk about something different. Have you ever done circuit simulation? In the past, working with microcontrollers meant a lot of hands-on practice, and I burned countless boards. But ever since I discovered Proteus, life has been much easier. I can tinker in the software first, and then implement it on the board, saving a … Read more
PMIC Report Overview Chips can generally be divided into two major categories: analog and digital chips. Among them, analog chips include analog signal chains, mixed-signal chips, power devices, RF devices, and sensors. Power devices are further divided into Power Management Integrated Circuits (PMICs) and power devices. The technologies and application areas involved in PMICs include … Read more
Audi, known as the “light factory,” has become a leader in automotive lighting research and has gained widespread recognition from consumers. It is noteworthy that among mainstream manufacturers, only Audi dares to use different DRL shapes on different models, while others stick to a uniform shape. Some say there are two types of car lights … Read more
A few days ago, my girlfriend wanted to buy a phone and asked me whether she should get the iPhone XR or the iPhone XS. I carefully explained the differences between the two. Apart from the basic parameters being the same, the iPhone XR uses an LCD screen, while the iPhone XS uses an OLED … Read more
In 2018, various smartphone manufacturers were fiercely promoting their products equipped with OLED screens, as if products without OLED screens were considered inferior. But is OLED really that much more advanced than LCD? Which is better, LCD or OLED? Why did the iPhone XR only use an LCD screen? Let’s compare the advantages and disadvantages … Read more
