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. + +regs Kusti, 23.10.2004 +*/ + + +#ifndef __TFP_PRINTF__ +#define __TFP_PRINTF__ + +#include <stdarg.h> + +void init_printf(void* putp,void (*putf) (void*,char));

For Freescale/NXP Kinetis support (meaning ARM Teensies and the Infinity keyboard), you'll also need [a zip of chibios-contrib](https://github.com/ChibiOS/ChibiOS-Contrib/archive/e1311c4db6cd366cf760673f769e925741ac0ad3.zip), unpacked/renamed to `tmk_core/tool/chibios/chibios-contrib`. Likewise, for git-savvy people, just clone [the repo](https://github.com/ChibiOS/ChibiOS-Contrib) there. +- Note: the abovementioned directories are the defaults. You can have the two chibios repositories wherever you want, just define their location in `CHIBIOS` and `CHIBIOS_CONTRIB` variables in your `Makefile`. +- You will also need to install an ARM toolchain, for instance from [here](https://launchpad.net/gcc-arm-embedded). On linux, this is usually also present as a package for your distribution (as `gcc-arm` or something similar). On OS X, you can use [homebrew](http://brew.sh/) with an appropriate tap. + +### Notes + +- Some comments about ChibiOS syntax and the most commonly used GPIO functions are, as well as an example for ARM Teensies, is [here](https://github.com/tmk/tmk_keyboard/blob/master/keyboard/teensy_lc_onekey/instructions.md). +- 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. +- For debugging, it is sometimes useful disable gcc optimisations, you can do that by adding `-O0` to `OPT_DEFS` in your `Makefile`. +- 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. +- 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`. An additional startup code is also needed; the best way to deal with this is to define custom board files. (Example forthcoming.) In any case, there are no problems for Teensies. + + +### Immediate todo + +- power saving for suspend + +### 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?)

I think people managed to get ChibiOS running on atmega32[8p/u4] though. +- There is also support for Nordic NRF51822 (the chip in Adafruit's Bluefruit bluetooth-low-energy boards), but be aware that that chip does *not* have USB, and the BLE softdevice (i.e. Bluetooth) is not supported directly at the moment. + +## 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. +- There is a working example of a STM32F042-based keyboard: [firmware here](https://github.com/flabbergast/flabber_kbs/tree/master/kb45p) and [hardware (kicad) here](https://github.com/flabbergast/kicad/tree/master/kb45p).
