WebDec 7, 2024 · Manipulating C strings safely. December 7, 2024 Leandro Francucci. Advertisement. A software failure due to an invalid string of characters is common in any software system, but it is a critical one in an embedded software written in C language because it frequently manipulates strings through specific functions defined in string.h, … WebMay 9, 2012 · But 4-bit mode uses only 4 data lines. In this mode the 8-bit ASCII data is divided into 2 parts which are send sequentially through data lines DB4 – DB7 with its own data strobe through the E line. The idea of 4-bit communication is to save as much pins that used to interface with LCD.
