-S60-x keyboard firmware
+S60-x keyboard firmware
======================
-DIY compact keyboard by Massdrop. This is a port from TMK to QMK based on the [original S60-X Repo](https://github.com/jpec/s60x).
+DIY compact keyboard designed by VinnyCordeiro for Sentraq. Most of the keymaps are based on GH60 code. This is a port from TMK to QMK based on the [original S60-X Repo](https://github.com/VinnyCordeiro/tmk_keyboard).

## Quantum MK Firmware
-For the full Quantum feature list, see [the parent readme.md](/doc/readme.md).
+For the full Quantum feature list, see [the parent readme.md](/readme.md).
-## Building
+## Keymap
+Several versions of keymaps are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `keymap_<name>.c` and see keymap document (you can find in top README.md) and existent keymap files.
-Download or clone the whole firmware and navigate to the keyboards/s60-x folder. Once your dev env is setup, you'll be able to type `make` to generate your .hex - you can then use the Teensy Loader to program your .hex file.
+To build firmware binary hex file with a certain keymap just run `make` with the `keymap` option like:
-Depending on which keymap you would like to use, you will have to compile slightly differently.
+ $ make keymap=[custom|poker|poker_set|poker_bit|plain|hasu|spacefn|hhkb|<name>]
-### Default
+File [S60-X_pre-compiled_firmwares.zip](S60-X_pre-compiled_firmwares.zip) contains pre-compiled firmwares for all keymaps available. Not all of them are tested.
-To build with the default keymap, simply run `make`.
-### Other Keymaps
+## Flashing your keyboard
+The recommended programs for flashing your keyboard are [Atmel FLIP](http://www.atmel.com/tools/FLIP.aspx) (Windows) and [dfu-programmer](http://dfu-programmer.sourceforge.net/) (Linux/Windows).
-Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create a folder with the name of your keymap in the keymaps folder, and see keymap documentation (you can find in top readme.md) and existant keymap files.
+[QMK Firmware Flasher](https://github.com/jackhumbert/qmk_firmware_flasher/releases) may work, as the S60-X keyboard uses the ATMega32U4 microcontroller, but it is untested. Use at your own risk.
-To build the firmware binary hex file with a keymap just do `make` with `keymap` option like:
+[Easy AVR USB Keyboard Firmware](https://deskthority.net/wiki/Easy_AVR_USB_Keyboard_Firmware) also supports S60-X, but it is completely unrelated to TMK firmware. Use at your own risk.
-```
-$ make keymap=[default|<name>]
-```
+**Programming the firmware (Windows)**
-Keymaps follow the format **__keymap.c__** and are stored in folders in the `keymaps` folder, eg `keymaps/my_keymap/` \ No newline at end of file
+1. download and install FLIP (http://www.atmel.com/tools/FLIP.aspx)
+2. connect the keyboard, press the program button (S1) and wait until it enumerates
+3. go to device manager, find the atmega32u4 chip and click "update driver"
+4. choose location manually: folder named "usb" inside the installation directory of FLIP
+5. once the driver is installed, run flip
+6. Device -> Select: choose ATMega32U4
+7. Settings -> Communication -> USB, FLIP should show the signature at this point (58 1E 95 87)
+8. File -> Load HEX file: choose the hex firmware: <firmware>.hex
+9. click "Run"
+10. after programming is done, disconnect the device from USB and connect again.
+
+
+**Programming the firmware (Linux)**
+
+1. Download and install/compile/unpack dfu-programmer from http://dfu-programmer.sourceforge.net/.
+2. Issue the following commands in the command prompt after connecting the device and pressing the programming button (S1). You may need root permissions or udev rules to do that.
+ 1. `sudo dfu-programmer atmega32u4 erase`
+ 2. `sudo dfu-programmer atmega32u4 flash <firmware>.hex`
+ 3. `sudo dfu-programmer atmega32u4 start`
+3. The keyboard should start working. If it doesn't, reconnect the cable.
+
+
+### 0 Initial explanations
+The █████ blocks on the layouts hides the switch positions that do not exist physically on the PCB. If you feel like hacking the keyboard and adding new keys, those are the positions that can be used. You'll have to modify the [keymap_common.h](keymap_common.h) file for that.
+
+The ▒▒▒▒▒ blocks hides switch positions not used on this particular layout, but they do exist on the PCB.
+
+There is no LED support on the PCB at the moment, but I'll let the code for that untouched.
+
+
+### 1 Standard - ANSI
+The standard keymap is the one that is pre-flashed on the S60-X.

+The custom keymap - [keymap_custom.c](keymap_custom.c) - is where I tested all the switches, not being concerned with a specific layout or layers. It's a plain layout option with the extra keys used on ISO & HHKB layouts being assigned some other keys.
