Question 3:
What are some of the procedures that the GCC compiler has at compile time?
After thinking, go down to find the answer
The answer to the first question:
The ls -a command displays all files in the current directory, including hidden files, and sends the results of the ls -a command through the pipe to the more command.
Question two answers:
Compile the source code test.c file into the target file test.elf file, and set gdb debugging switch to test.elf
Question 3 Answer:
Gcc compiles c source code in four steps: preprocessing, compiling, compiling, and linking.
Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
