Is it simulation? Or in kind?
Is it simulation? Or in kind?. Send a picture. There are two reasons, one is the circuit problem, the other is the program problem.. But these two, did not send up, so, not sure what the reason.. three point five   LCD 1602 character LCD module 3.5.1 design purpose and task design task: design a character LCD, familiar with HD44780 and its compatible LCD controller instruction set and its use method; Familiar with the use of 8155 parallel port expansion chip; Familiar with keil uv2 integrated development environment; Familiar with STC ISP software. Function index: the display can display the characters in any ASCII code table at any position.
