Roving RN-42
============
-07/16 After fix of voltage dividor on GPIO6, had a trouble that it could not send a char to BT module, though could receive.
- Found R8 had wrong 1K resistor and changed to 10K, after that it can send to the module again. Not sure how it had sent with the wrong 1K before.
-07/18 On Linux, had an USB related trouble; keyobard or console didn't work for some reason. Changing PID cured this problem. Very annoying, took very long time before resolved it.

TODO

+Power saving:
+- When not connected in a few minuts get into deep sleep to save battery life
+- CTS is needed for waking up from deep sleep? How deep sleep is activated?
+
+Improving:
+- Status LED; connecting, liked, low battery, sleeping, deep sleeping
+- Battry voltage display by command; like full(solid), medium(blink), low(flash)
+- move rn42 to protocol directory when it becomes reusable stack
- LUFA sendchar should be buffered and serial_uart.c buffur size is too large(256).
-- Factroy reset doesn't work; need to test again. 10K pull-up is too high?
-- Lipo voltage ADC sensing
-- Lipo charger configuration: fast charge time: USB charger spec?
-- Low voltage alarm: LED indcates voltage of Lipo
-- CTS/RTS lines are needed? just connect in loop back if no flow control is needed.
-- CTS is needed for waking up from deep sleep?
-- Serial API callback when data are available/received(and when send buffer is available)
-- Serial API instance several serial ports can be used
-- DCDC converter: squeaky inducter with onsemi NCP1402
-- Lipo charger MCP73831: needs capacitor 4.7uF *2
+
+Testing:
+- Factroy reset doesn't work; need to **test again** 10K pull-up is too high?
+- Lipo voltage ADC value is not stabilized
+- DCDC converter: squeaky inducter; try other inductors
+
- Keymap layer bug: during space is pressed(mousekey) press Fn(HHKB) then release space before Fn, in result HHKB layer is locked(toggled) unintentionally.
+
DONE:
+- Lipo charger configuration: fast charge time: USB charger spec? -- used 2kohm
+- use LED of charger to alarm low battery. LED should be powered directly from Lipo? - cancel; powered from VUSB
+- Use RTS in serial_uart.c to resolve missing chars from help message of RN-42 - done
+- CTS/RTS lines are needed? just connect in loop back if no flow control is needed. - done
+- add IO pin to charger status CHRG; LED control(low) and detect charge status(input HiZ) 07.24
+- LINKED: add trace on PIO2 to PF6 07.24
+- Lipo voltage ADC sensing
+- Lipo charger MCP73831: needs capacitor 4.7uF *2
- USB connection check - 07.01
- BT on/off check: whether RX line is pulled up? - checking RTS 07.01
- USB/BT switching BT is on -> BT, BT is off -> USB - 07.01
