Binary file converter to C/C++ source header

bin2header's Issues

Add few more options

Add a fewoptions to make tool more usefull:
-add option to start with an offset and for only given length
-add option to pack data into 16/32 bit word (and swap endianess if needed)

bin2header generates invalid identifier names

I have a series of files called things like 36.bin - bin2header will generate an array called 36 with #defines for 36_H. Neither of those are valid names.

It should really know what a valid C identifier looks like to warn you. Or perhaps allow the user to supply a name on the command line? Or add a prefix (e.g. DATA) to the front of names starting with a digit?

File Size Limitation

As reported by a user, it appears that bin2header has a limit on how large of a file it can handle. This limitation may be different depending on operating system & available system resources. I have mostly tested the program with image files, & probably nothing bigger (at most) than a couple megabytes. It appears that when the program attempts to load a file larger than it can handle, it crashes without any helpful information about the error.

There are two things that I want to do:

First, have the program recognize when it cannot handle a file due to size limitations & output error details for the user without crashing.

Second, I want to increase, or perhaps abolish, the limitation on file size. Off-hand, I think a solution would be to set a chunk size for the program to process at a single time, rather than attempting the load the entire file all at once. Perhaps this chunk size could be manually adjusted by the user.

NOT AN ISSUE but how does this work

i am new to these kind of stuff but i can't get it to run yesterday i waisted 3 hours on this and today already 2 and i can't get my grasp on what it is i downloaded this git and also the sourceforge version.

does not work for SDD1306 display

I'm trying to convert a BMP in 128x32 size
for use a custom Adafruit splash screen .
Example https://github.com/adafruit/Adafruit_SSD1306/tree/master/examples/ssd1306_128x32_i2c
replace const uint8_t PROGMEM splash2_data[] in /home/youruser/Arduino/libraries/Adafruit_SSD1306/Splash.h
I got a distorted pixel mesh .

Original splash :
const uint8_t PROGMEM splash2_data[] = { 0b00000000,0b00000000,0b01100000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000, 0b00000000,0b00000000,0b11100000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,0b00000000,

Updated from what I got from bin2header :

const uint8_t PROGMEM splash2_data[] = { 0x42, 0x4d, 0x8a, 0x14, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x8a, 0x04, 0x00, 0x00, 0x7c, 0x00, 0x00, 0x00, 0x80, 0x00, 0x00, 0x00, 0x20, 0x00, 0x00, 0x00, 0x01, 0x00, 0x08, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x10, 0x00, 0x00, 0x23, 0x2e, 0x00, 0x00, 0x23, 0x2e, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x00, 0xff, 0x00, 0x00, 0xff, 0x00, 0x00, 0xff, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x42, 0x47, 0x52, 0x73, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,

Comment shows data context

A comment at the end of any line should show the containing data as ascii chars (dot for not printable chars).
