CodeRed for mbed

I searched the forum for mbed and discovered a few references of using the mbed without the online compiler.

Can an offline compiler - such as the CodeRed - be used with the mbed? The limitations of the online compiler is the singular deterrent to using the mbed in field trials and pre-production units.

Of course, create a bin file and 'Save the program binary file to your mbed Microcontroller Disk,'

as described here:

That's all :)

I tried this with the LPCXpresso tools.
I had a small program with 1 PWM outputs which resulted in a 15 kB .bin file on the mBed online compiler and 67 kB on the LPCXpresso tools (actually the debug build is 66.8 kB and the release build 66.7 kB :eek:)

The standard led blinking that you get for free in every new program on mBed is 3.7 kB on the mBed compiler and 59 kB on LPCXpresso.

There must be something very wrong with either the tool settings or the libraries. I'd love to use C++ for my application but > 50 kB overhead is just too much - my current MCU is an lpc1754 with 128 kB Flash.

maybe the online compiler is using smaller standard libs, that makes a big difference. You can try to change the linker file and use the nano libs instead:

/* GROUP(libgcc.a libc.a libstdc++.a libm.a libcr_newlib_nohost.a crti.o crtn.o crtbegin.o crtend.o) */
GROUP(libgcc.a libc_nano.a libstdc++_nano.a libm.a libcr_newlib_nohost.a crti.o crtn.o crtbegin.o crtend.o)
