Since the late 1970s, with the birth of the microcontroller, there has been a considerable history of development in microcontrollers. Because microcontrollers are more suitable for embedded systems and have strict volume management, almost every electronic device you see today integrates a microcontroller. The widespread application means that learners of microcontrollers have a wealth of … Read more
There are only two operations for the 1602: reading and writing. Reading can be divided into reading status (status register) and reading data (from RAM), while writing can be divided into writing instructions and writing data (to RAM). All operation timing needs to follow the table below. During usage, I encountered a situation where nothing … Read more
