Pointer arithmetic allows arithmetic operations on pointers in C, such as addition and subtraction. However, since pointers store addresses, performing arithmetic operations with integer types will result in a pointer. When subtracting one pointer from another, the result will be an integer value. In C, you can perform the following arithmetic operations on pointers: Increment … 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
