Covid HW 08 - Display and files

Expected results:

• main.c file for NUCLEO with following functionality:
  • The program in NUCLEO will be able to draw primitives from a file stored on the computer.
  • The NUCLEO will implement handler for test commands.
• chw8.c file for PC where
  • The program expects a file name given on the command line
  • The program opens the file and send the content of this file line by line to NUCLEO.
  • When JOY_DOWN is received, the program sends the “DRAW:CLEAR 9” message to NUCLEO.
  • When computer receives JOY_SEL, the commands from the file are sent to the NUCLEO again.

The NUCLEO will interact with your C program and this program expects a file name to be given on the command line. The sample of this file is as follows:

*IDN?
DRAW:*IDN?
DRAW:CLEAR 2
DRAW:SETTEXTCOLOR 3 
DRAW:CIRCLE 49,20
DRAW:CIRCLE 79,20,10
DRAW:SETTEXTCOLOR 2 
DRAW:LINE 55,40,60,45 
DRAW:LINE 68,45,73,40 
DRAW:LINE 60,45,68,45 
DRAW:SETFONT 12
DRAW:TEXT 64,120,Nucleo RULEZ!,1

All handlers for single commands should be implemented. When command is not recognized by NUCLEO return “Wrong command\r\n” and the C program
