+
+This library is realy just two files: 'printf.h' and 'printf.c'.
+
+They provide a simple and small (+200 loc) printf functionality to
+be used in embedded systems.
+
+I've found them so usefull in debugging that I do not bother with a
+debugger at all.
+
+They are distributed in source form, so to use them, just compile them
+into your project.
+
+Two printf variants are provided: printf and sprintf.
+
+The formats supported by this implementation are: 'd' 'u' 'c' 's' 'x' 'X'.
+
+Zero padding and field width are also supported.
+
+If the library is compiled with 'PRINTF_SUPPORT_LONG' defined then the
+long specifier is also
+supported. Note that this will pull in some long math routines (pun intended!)
+and thus make your executable noticably longer.
+
+The memory foot print of course depends on the target cpu, compiler and
+compiler options, but a rough guestimate (based on a H8S target) is about
+1.4 kB for code and some twenty 'int's and 'char's, say 60 bytes of stack space.
+Not too bad. Your milage may vary. By hacking the source code you can
+get rid of some hunred bytes, I'm sure, but personally I feel the balance of
+functionality and flexibility versus code size is close to optimal for
+many embedded systems.
+
+To use the printf you need to supply your own character output function,
+something like :
+
+ void putc ( void* p, char c)
+ {
+ while (!SERIAL_PORT_EMPTY) ;
+ SERIAL_PORT_TX_REGISTER = c;
+ }
+
+Before you can call printf you need to initialize it to use your
+character output function with something like:
+
+ init_printf(NULL,putc);
+
+Notice the 'NULL' in 'init_printf' and the parameter 'void* p' in 'putc',
+the NULL (or any pointer) you pass into the 'init_printf' will eventually be
+passed to your 'putc' routine. This allows you to pass some storage space (or
+anything realy) to the character output function, if necessary.
+This is not often needed but it was implemented like that because it made
+implementing the sprintf function so neat (look at the source code).
+
+The code is re-entrant, except for the 'init_printf' function, so it
+is safe to call it from interupts too, although this may result in mixed output.
+If you rely on re-entrancy, take care that your 'putc' function is re-entrant!
+
+The printf and sprintf functions are actually macros that translate to
+'tfp_printf' and 'tfp_sprintf'. This makes it possible
+to use them along with 'stdio.h' printf's in a single source file.
+You just need to undef the names before you include the 'stdio.h'.
+Note that these are not function like macros, so if you have variables
+or struct members with these names, things will explode in your face.
+Without variadic macros this is the best we can do to wrap these
+fucnction. If it is a problem just give up the macros and use the
+functions directly or rename them.
+
+For further details see source code.

### 2. Change directory
Move to project directory in the firmware source.
How to program controller depends on controller chip and its board design. To program AVR USB chips you'll need to start it up in bootloader mode. Most of boards with the chip have a push button to let bootloader come up. Consult with your controller board manual.
### 2. Program with DFU bootloader
-Stock AVR USB chip including ATmega32U4 has DFU bootloader by factory default. `FLIP` is a DFU programmer on Windows offered by Atmel. Open source command line tool `dfu-programmer` also supports AVR chips, it runs on Linux, Mac OSX and even Windows.

+## TMK running on top of ChibiOS
+
+### Notes
+
+- To use, unpack or symlink [ChibiOS] {currently 3.0.2} to `tmk_core/tool/chibios/chibios`. For Kinetis support, you'll need a fork which implements the USB driver, e.g. [this one](https://github.com/flabbergast/ChibiOS/tree/kinetis).
+- For gcc options, inspect `tmk_core/tool/chibios/chibios.mk`. For instance, I enabled `-Wno-missing-field-initializers`, because TMK common bits generated a lot of warnings on that.
+Also pay attention to `-O0` (enabled for debugging); for deployment use `-O2`.
+- USB string descriptors are messy. I did not find a way to cleanly generate the right structures from actual strings, so the definitions in individual keyboards' `config.h` are ugly as heck.
+- There are some random constants left so far, e.g. 5ms sleep between calling `keyboard_task`, or 1.5sec wait for USB init, in `main.c`. There should be no such in `usb_main.c` (the main USB stack). Everything is based on timers/interrupts/kernel scheduling (well except `keyboard_task`), so no periodically called things (again, except `keyboard_task`, which is just how TMK is designed).
+- It is easy to add some code for testing (e.g. blink LED, do stuff on button press, etc...) - just create another thread in `main.c`, it will run independently of the keyboard business.
+- Jumping to (the built-in) bootloaders on STM32 works, but it is not entirely pleasant, since it is very much MCU dependent. So, one needs to dig out the right address to jump to, and either pass it to the compiler in the `Makefile`, or better, define it in `<your_kb>/bootloader_defs.h`. Also, a patch to upstream ChibiOS is needed (supplied), because it `ResetHandler` needs adjusting.
+- Sleep LED works, but at the moment only on/off, i.e. no breathing.
+
+### Immediate todo
+
+- host-wakeup packet sending during suspend
+- power saving for suspend?
+- PWM for sleep led
+
+### Not tested, but possibly working
+
+- backlight
+
+### Missing / not working (TMK vs ChibiOS bits)
+
+- eeprom / bootmagic for STM32 (will be chip dependent; eeprom needs to be emulated in flash, which means less writes; wear-levelling?) There is a semi-official ST "driver" for eeprom, with wear-levelling, but I think it consumes a lot of RAM (like 2 pages, i.e. 1kB or so).
+
+### Tried with
+
+- ChibiOS 3.0.1, 3.0.2 and ST F072RB DISCOVERY board.
+- Need to test on other STM32 chips (F3, F4) to make it as much chip-independent as possible.
+- ChibiOS with Kinetis patches and Teensy LC and 3.0.
+
+## ChibiOS-supported MCUs (as of 3.0.2)
+
+- Pretty much all STM32 chips.
+- There is some support for K20x and KL2x Freescale chips (i.e. Teensy 3.x/LC, mchck, FRDM-KL2{5,6}Z, FRDM-K20D50M), but again, no official USB stack yet. However the `kinetis` branch of [my ChibiOS fork](https://github.com/flabbergast/ChibiOS). With this fork, TMK work normally on all the ARM Teensies.
+- There is also support for AVR8, but the USB stack is not implemented for them yet, and also the kernel itself takes about 1k of RAM. I think people managed to get ChibiOS running on atmega32[8p/u4] though.
+- I've seen community support for Nordic NRF51822 (the chip in Adafruit's Bluefruit bluetooth-low-energy boards), but not sure about the extent.
+
+## STM32-based keyboard design considerations
+
+- STM32F0x2 chips can do crystal-less USB, but they still need a 3.3V voltage regulator.
+- The BOOT0 pin should be tied to GND.
+- For a hardware way of accessing the in-built DFU bootloader, in addition to the reset button, put another button between the BOOT0 pin and 3V3.
+- For breathing the caps lock LED during the suspended state ("sleep LED"), it is desirable to have that LED on a hardware PWM pin (there's usually plenty of those, look for TIMERs in the datasheet). However this is not strictly necessary, because instead of direct output of a timer to a pin (better of course), it is easy to define timer callbacks in ChibiOS that turn on/off an arbitrary pin.
