Markus Hitter 8377de8d66 ARM: get delay.c in. 
Accuracy is pretty good, see committed comments :-)

Code used for testing, in main():

  uint32_t i;

  SET_OUTPUT(PIO0_1);
  while (1) {
    // 10 seconds for each frequency, so we
    // can measure all three with one upload.
    for (i = 10000; i > 0; i--) {
      WRITE(PIO0_1, 1);
      delay_us(1000);
      WRITE(PIO0_1, 0);
      delay_us(1000);
    }
    for (i = 1000; i > 0; i--) {
      WRITE(PIO0_1, 1);
      delay_us(10000);
      WRITE(PIO0_1, 0);
      delay_us(10000);
    }
    for (i = 200; i > 0; i--) {
      WRITE(PIO0_1, 1);
      delay_us(65000);
      WRITE(PIO0_1, 0);
      delay_us(65000);
    }
  }

Markus Hitter 52e2585f13 ARM: use arduino.h for UART pinout. 
This removes another 36 bytes binary size and six(!) MBED files.

The mess of MBED files is now pretty much resolved, only a few
essential ones left.

Markus Hitter 43b2ac6e0b ARM: get sersendf.c/.h in. 
Needed a bit a tweak to adjust va_arg() to 32 bit. Tests ran fine,
at the end it turned out mendel.c had an obsolete #include.

Markus Hitter 5dec638919 ARM: get sermsg.c/.h in. 
Compiled flawlessly, ran all test flawlessly, and at the end it
turned out mendel.c had an obsolete #include. Very nice.

Markus Hitter 829e4d475b Makefiles: add a hint on how to list these predefined macros. 
No functional change.

Markus Hitter 52f5a56d71 ARM: move serial handling code directly into serial-arm.c. 
This makes another seven mbed files obsolete and reduces binary
size by another 100 bytes Flash and 16 bytes RAM:

    SIZES          ARM...     lpc1114
    FLASH  :  1624 bytes           5%
    RAM    :   140 bytes           4%
    EEPROM :     0 bytes           0%

Markus Hitter 776f90ff2c ARM: simplify serial and get rid of mbed-pinmap_common.c. 
We have only one UART, we use only one UART, so it's pointless to
do pin mapping calculations at runtime.

Binary size down by 268 bytes:
    SIZES          ARM...     lpc1114
    FLASH  :  1724 bytes           6%
    RAM    :   156 bytes           4%
    EEPROM :     0 bytes           0%

Markus Hitter a5cb1bd31a ARM: get rid of mbed-mbed_error.h and mbed-error.c. 
Same functionality, drastically smaller binary:

    SIZES          ARM...     lpc1114
    FLASH  :  1992 bytes           7%
    RAM    :   156 bytes           4%
    EEPROM :     0 bytes           0%

That's a reduction by 3948 bytes Flash and 20 bytes RAM.

Markus Hitter 4cfeca08e1 ARM: get serial working based on MBED code. 
Pretty complex, this MBED system, it requires no less than
24 additional files. This will be fleshd out before too long.

    SIZES          ARM...     lpc1114
    FLASH  :  5956 bytes          19%
    RAM    :   176 bytes           5%
    EEPROM :     0 bytes           0%

Markus Hitter 9e9e946c6d Makefile-ARM: get uploading to work. 2015-08-12 14:26:34 +02:00
Markus Hitter 3cc81cdba8 Makefile-ARM: adjust sizes reporting to our only target. 2015-08-12 14:26:33 +02:00
Markus Hitter 575174940f ARM: get a minimum amount of Teacup compiled for ARM. 
Makefile can't even upload, yet.

    SIZES          ARM...     lpc1114
    FLASH  :   944 bytes           3%
    RAM    :   132 bytes           4%
    EEPROM :     0 bytes           0%
