ASSEMBLY LANGUAGE

Assembly programming language as it applies to embedded microcontroller applications. This programming needed programmer for declaring variables and constant do loops, testing the logic analyzer. In c programming there are several types of loops. Next, the important part is software to interface with PIC. The software used is assembly programming. Assembly compiler is software to write, simulate and burn the program into PIC.  To ensure written programming worked or not, it can combine with software Proteus. From this software, the program can be simulated with circuit

Normal PC hardware might well run with just T_x, R_x and Ground connected, most driver software will wait forever for one of the handshaking lines to go to the correct level. Depending on the signal state it might sometimes work, other times it might not. The reliable solution is to loop back the handshake lines if they are not used.
