Parsing C defines and converting it to Python code

While trying to port some C code to micropython, I needed to set a lot of defines in a code as Python global vars.

Given those defines :
    
    #define    CMD_SIZE                           512	
    
    /*
    frame format
    */
    #define    FRAME_B                            0xA5
    #define    FRAME_E0                           0xCC
    #define    FRAME_E1                           0x33
    #define    FRAME_E2                           0xC3
    #define    FRAME_E3                           0x3C
    
    
    /*
    color define
    */
    #define    WHITE                              0x03
    #define    GRAY                               0x02
    #define    DARK_GRAY                          0x01
    #define    BLACK                              0x00
    
    /*
    command define
    */
    #define    CMD_HANDSHAKE                      0x00                                                     //handshake
    #define    CMD_SET_BAUD                       0x01                                                     //set baud
    #define    CMD_READ_BAUD                      0x02                                                     //read baud
    #define    CMD_MEMORYMODE                     0x07                                                     //set memory mode
    #define    CMD_STOPMODE                       0x08                                                     //enter stop mode 
    #define    CMD_UPDATE                         0x0A                                                     //update

    #define    CMD_LOAD_FONT                      0x0E                                                     //load font
    #define    CMD_LOAD_PIC                       0x0F                                                     //load picture
    
    #define    CMD_SET_COLOR                      0x10                                                     //set color

    #define    CMD_DRAW_STRING                    0x30                                                     //draw string

    #define    EPD_INVERSION                      1                                                        //screen inversion

Here is the regexp I used :

b = re.findall("\#define +([a-zA-Z0-9_]+) +([0-9xA-Z_]+)( +//(.+))?", my_text)

My code to print it :

for item in b:
         l = item[0] + " = " + item[1]
         if item[3]:
             l += " # " + item[3]
         print(l)

The result :

CMD_SIZE = 512
    FRAME_B = 0xA5
    FRAME_E0 = 0xCC
    FRAME_E1 = 0x33
    FRAME_E2 = 0xC3
    FRAME_E3 = 0x3C
    WHITE = 0x03
    GRAY = 0x02
    DARK_GRAY = 0x01
    BLACK = 0x00
    CMD_HANDSHAKE = 0x00 # handshake
    CMD_SET_BAUD = 0x01 # set baud
    CMD_READ_BAUD = 0x02 # read baud
    CMD_MEMORYMODE = 0x07 # set memory mode
    CMD_STOPMODE = 0x08 # enter stop mode 
    CMD_UPDATE = 0x0A # update
    CMD_SCREEN_ROTATION = 0x0D # set screen rotation
    CMD_LOAD_FONT = 0x0E # load font
    CMD_LOAD_PIC = 0x0F # load picture
    CMD_SET_COLOR = 0x10 # set color
    CMD_SET_EN_FONT = 0x1E # set english font
    CMD_SET_CH_FONT = 0x1F # set chinese font
    CMD_DRAW_PIXEL = 0x20 # set pixel
    CMD_DRAW_LINE = 0x22 # draw line
    CMD_FILL_RECT = 0x24 # fill rectangle
    CMD_DRAW_CIRCLE = 0x26 # draw circle
    CMD_FILL_CIRCLE = 0x27 # fill circle
    CMD_DRAW_TRIANGLE = 0x28 # draw triangle
    CMD_FILL_TRIANGLE = 0x29 # fill triangle
    CMD_CLEAR = 0x2E # clear screen use back color
    CMD_DRAW_STRING = 0x30 # draw string
    CMD_DRAW_BITMAP = 0x70 # draw bitmap
    GBK32 = 0x01
    GBK48 = 0x02
    GBK64 = 0x03
    ASCII32 = 0x01
    ASCII48 = 0x02
    ASCII64 = 0x03
    MEM_NAND = 0
    MEM_TF = 1
    EPD_NORMAL = 0 # screen normal
    EPD_INVERSION = 1 # screen inversion
    
Voilà !
