Memo of deveopment
|
||||
==================
|
||||
just memo, NOT WORTH READING
|
||||
|
||||
2015/11/24
|
||||
JP Bluetooth:
|
||||
RN-42 cannot send Japanese keys like; henkan, mu-henkan and kana, JPY and RO.
|
||||
It seems HID usage more than 0x65 cannot be send with the module.
|
||||
http://shiki.esrille.com/2014/07/bluetoothnisse.html
|
||||
|
||||
|
||||
Bug:
|
||||
- Factory Reset PIO4 doesn't work
|
||||
- the reason is unclear - 12/08 NOT LOOK INTO ANY MORE
|
||||
- WORKAROUND: use serial pins(3.3V, GND, RX and TX)
|
||||
- SF,1 and R,1 to set factory defalult
|
||||
|
||||
|
||||
Todo:
|
||||
- LED cover and switch knob and new Slide Switch
|
||||
- RN42 auto configuration
|
||||
- configure the module as HID device every time powering up
|
||||
- this'll reduce work load of assembly
|
||||
|
||||
- move rn42 to protocol directory when it becomes reusable stack
|
||||
|
||||
- sendchar() in lufa.c no buffer
|
||||
- no buffering. character lost can be caused.
|
||||
- LUFA sendchar should be buffered and serial_uart.c buffur size is too large(256).
|
||||
|
||||
- BT operations
|
||||
- disconnect
|
||||
- new connection
|
||||
- remove connection
|
||||
|
||||
- sendchar() in lufa.c block loop - DONE 11/29
|
||||
- block loop when powered with AC adapter
|
||||
- FrameNumber is not updated when adapter powered
|

|
||||
- disable digital input buffer DIDR(7.8.6)
|
||||
|
||||
Design:
|
||||
- suspend.h - DONE 11/26
|
||||
- remove argument from suspend_power_down() for backward compatitibility
|
||||
- remove MCU dependent power saving code from core/keyboard - DONE 11/23
|
||||
- it should be located in project matrix.c
|
||||
- HHKB matrix.c needs matrix_prev?
|
||||
- is_modified() is obsolete now. really needs?
|
||||
- ADC: removing AREF capacitor C10
|
||||
- seems to be better while usb powered
|
||||
- still bad while battery powered

TROUBLE SHOOT
|
||||
-------------
|
||||
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; keyboard or console didn't work for some reason. Changing PID cured this problem. Very annoying, took very long time before resolved it.
|
||||
|
||||
12/07 rn42_rts() read 1 every time. R12 broke in open mode(no coductive), idk why, too much heat with soldering? and PF1 pin was not soldered.
|
||||
It resolved with resoldering PF1 and new resistor on R12.
|
||||
|
||||
|
||||
|
||||
|
||||
Done:
|
||||
- low battery alert(solid light) 09/04
|
||||
- *** Rev.E BT test *** - DONE
|
||||
- with MCP73832, new Schottky, tantalum caps - DONE 12/07
|
||||
* MCP73832 doesn't leak from Vcc pin when unpluged and battery powered
|
||||
34mV vs 2.07V(MCP73831) at Vcc pin
|
||||
MCP73832 doesn't need revese protection diode D5
|
||||
* PMEG2010ER is very low VF while reverse current/voltage is high
|
||||
VF=0.96 vs 1.98(RB160M-30TR)with Fluke 175
|
||||
Anode of D11 is 680mV vs 20mV(RB160M-30TR)
|
||||
780mV is still low < 1.4V VBUS plugin detection(21.11)
|
||||
this doesn't cause false VBUS detect
|
||||
and 780mV on MCP73832 Vcc pin is also no problem.
|
||||
D5 can be removed.
|
||||
- ADC divider switching - DONE 12/07
|
||||
* Drain and Source of Q4 Pch was reversed wrongly on Rev.E.
|
||||
|
||||
- reverse current from Lipo charger - DONE 12/07
|
||||
* MCP73832 has no recverse current from Vcc pin unlike MCP73831
|
||||
|
||||
|
||||
- Rev.F design - DONE
|
||||
- current measure point - DONE 12/08
|
||||
- change value of cap 68->47 - DONE 12/08
|
||||
- PPTC land pattern: no solder jumper, use 0Ohm resistor instead - CANCEL 12/08
|
||||
- Q4 Pch FET: wrong Drain and Source - DONE 12/08
|
||||
- D5 can be removed. - DONE 12/08
|
||||
|
||||
|
||||
|
||||
- BT_INDICATOR LED turns on wrongly when touching line or pin. -- pull-up enabled on PF6/GPIO2 08/30
|
||||
- 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
|
||||
- Under voltage lock out UVLO for protection of Lipo - Lipo has discharge protection at 3.100V 07.01
|
||||
- Power saving: HHKB scan, BT radio control - 9h with 850mAh, this is enough 07.01
|
||||
- Power selector doesn't work; Q4 MOSFET leaks from Lipo to USB power line. -- use Schottky instead 07/04
|
||||
|
||||
- wrongly suspended when powered from adapter without USB connection - DONE
|
||||
- suspend event may occur when plug into adapter
|
||||
- and never wake until conected to real USB line
|
||||
- without debug print via USB no problem; CSW(wake just after suspend as real USB line)
|
||||
- seems like USB print causes this problem after suspended
|
||||
|
||||
- lose USB connection during power-down mode - DONE
|
||||
- USB initialize code in main() causes this - WRONG
|
||||
- Do not power-down during USB connection is active - DONE 11/11
|
||||
(USB_DeviceState == USB_DEVICE_Configured) is used to check USB connection
|
||||
matrix_power_down() matrix.c - 11/23
|
||||

||||
- When given power only from wall wart adapter - DONE? not confirmed 01/15
|
||||
- it sleeps. it should not sleep
|
||||
- Configured state without USB connection?
|
||||
|
||||
- timer is slow while power down - DONE 11/26
|
||||
- time out interrupt is lost while power down?
|
||||
- interrupt of watchdog timer compensates timer counter(avr/suspend.c)
|
||||
|
||||
- repeated CHARGING/FULL_CHARGED - No longer problem 01/15
|
||||
- In LTC sharp pulses are observed.
|
||||
- MCP has no pulse but still has a problem.
|
||||
- needs more wait before read pin state? - NO
|
||||
|
||||
- USB plug-in fails while BT - No longer problem 01/15
|
||||
- it ends in suspend state
|
||||
- maybe, not responsive to host enumeration process due to power-down.
|
||||
- matrix_power_down() only when state is unattached - 11/26
|
||||
- need to observe a while

MOS FET Nch: BSS138 or IRLML6344T, either works and no apparent difference.
|
||||
Normally on(pull-up) or off(pull-down)? interms of power saving it prefers pull-down?
|
||||
|
||||
Pull-down will be better for power saving, normally off.

Hardware USART doesn't work at 115200bps with 8MHz(F_CPU).
|

|

workaround:
|

a) use Sotwre serial for communcation with RN-42
|

b) reduce baud of RN-42 to lower rate;(factory default is 115200bps)

RN-42 Bluetooth Module Support
|
||||
==============================
|
||||
Bluetooth controller board works with HHKB Pro2, JP, Type-S and Type-S JP and it supports both USB and Bluetooth as keyboard output protocol. Bluetooth module Roving Networks/Microchip RN-42 is installed on the board.
|
||||
|
||||
|
||||
RN-42:
|
||||
http://www.microchip.com/wwwproducts/Devices.aspx?product=RN42
|
||||
|
||||
|
||||
Capabitlities:
|
||||
- USB keyboard functions
|
||||
completely equivarent to USB controller including mouse keys and NKRO.
|
||||
- Switching between USB and Bluetooth
|
||||
You can switch the two connections with BT switch or key combination.
|
||||
- RN-42 config mode
|
||||
You can change power/connection configuration of the module if needed.
|
||||
- Low battery alert
|
||||
Red LED turns on when low voltage.
|
||||
- RN-42 status indicator
|
||||
LED indicates status of Bluetooth connection.
|
||||
- Pairing
|
||||
The module stores up to 8 connections.
|
||||
- Auto connect
|
||||
The module connects the last connected device automatically.
|
||||
- iOS support
|
||||
works as keyboard with iPhone5. No tested completely.
|
||||
- Android support
|
||||
works as keyboard and mouse with Nexus5. No tested completely.
|
||||
- Mouse keys over BT
|
||||
Note that iOS doesn't accept mouse device.
|
||||
|
||||
|
||||
Limitations:
|
||||
- Short battery life
|
||||
Around 12hr with 1000mAh
|
||||
- No connection switching
|
||||
RN-42 auto-connects to the last connected device.
|
||||
Some of consumer products can switch between devices, for example Logitech K480.
|
||||
http://www.logitech.com/en-us/product/multi-device-keyboard-k480?crid=26
|
||||
- HHKB JP requires case modification for BT switch and LEDs.
|
||||
without switch power controlled by MCU? Probably using 3.3V regulator enable pin power of RN-42 can be controlled.
|
||||
|
||||
NOTE:
|
||||
- LIPO BATTERY IS VERY DANGEROUS, TAKE EXTRA CARE OF YOUR SAFETY AND PROPERTY.
|
||||
- RN-42 version 6.15 is supported.
|
||||
- No NKRO over Bluetooth
|
||||
- Check you country's wiress regulation and certification of RN-42.

Keyboard can be used with iPhone, but mouse cannot.
|

Android
|

-------
|

3.7.1.5 Note: To connect with Android phone the modules must wake up 11ms every 2.5seconds.
|
||||
|
||||
|
||||
Power Management
|
||||
----------------
|
||||
Inquiry and Page window Idle or Active (3.1.1)
|
||||
Downside: delay in discovery or connection time
|
||||
SI, // set inquiry scan window(discovery) on/off duty?
|
||||
SJ, // set page scan window(connection)
|
||||
This reduces averaege power >20mA to 5mA(3mA in Sniff mode)
|
||||
|
||||
Sniff mode Transmit
|
||||
Sniff mode is disabled by default and radio is active continuously when connected.(25-30mA)
|
||||
In Sniff mode the radio wakes up intermittently and sleeps in very low power mode.(2mA)
|
||||
SW,<val> // set interval timer(*0.625ms) 0000-7FFF
|
||||
|
||||
Deep sleep Idle (3.1.2)
|
||||
In this mode the module shuts down completly and only draws about 300uA. To enable this set the most signifant bit(0x8000) of Sniff interaval timer.
|
||||
SW,8320 // deep sleep enable(interval=0x320*0.625=500ms)
|
||||
In normal sleep the firmware is still running in idle mode, and wakes up about 20 times per second to check ports, update LEDs, etc. During deep sleep, the firmware actually stops runnig some tasks and the LEDs only update about once per second.
|
||||
To wake from deep sleep there are three ways: (in worst case wake up takes 5ms)
|
||||
*send a charactor to the UART(first charactor will be lost)
|
||||
*toggle CTS low to high and wait 5ms
|
||||
*wake automatically every slot time(<val>*0.625ms)
|
||||
Once the radio is awake it stay active for exactly 1 second of inactivity and then sleeps again.
|
||||
Downside: latency and data loss
|
||||
|
||||
Disable Output driver Idle or Active (3.1.3)
|
||||
S%,1000 // set all GPIO pins(0-11) to inputs.
|
||||
|
||||
Lower Transmit Power Idle or Active (3.1.4)
|
||||
SY,<hex> // transmit power setting(takes effect after a power cycle and reboot)
|
||||
Downside: reducing effective range
|
||||
|
||||
|
||||
Optimizig for Latency
|
||||
---------------------
|
||||
By default the firmware is optimized for throughput.
|
||||
SQ,16 // set latency bit
|
||||
SQ,0 // unset latency bit
|
||||
|
||||
|
||||
Configuration timer settings
|
||||
----------------------------
|
||||
Remote configuration is used for the module to be configured with various commands over Bluetooth(SPP profile only?).
|
||||
|
||||
The module has remote configuration timer to allow remote configuration over Bluetooth after power up in Slave mode. In Master modes the remote configuration timer is set to 0(no remote configuration). (In Trigger Master mode the timer is used as an idle timer to break the connection after time expires with no charactors receive.)
|
||||
ST,0 // no remote, no local when connected
|
||||
ST,<1-252> // local and remote with timeout in seconds from power up
|
||||
ST,253 // local only without timeout
|
||||
ST,254 // remote only without timeout
|
||||
ST,255 // local and remote without timeout
|
||||
