Bulegiga WT12
|
||||
=============
|
||||
WT12 is a bluetooth module from Bluegiga. http://www.bluegiga.com/
|
||||
|
||||
iWRAP
|
||||
higher layer interface for bluetooth firmware
|
||||
communicate with UART
|
||||
|
||||

|
||||

Problems
|
||||
--------
|
||||
power consumption
|
||||
no consumer page support(bug?)
|
||||
no mouse wheel support
|
||||
no paring management
|
||||
no interactive auth method
|
||||
|
||||
|
||||
UART hardware flow control
|
||||
--------------------------
|
||||
(iWRAP4 User Guide 9.5)
|
||||
Hardware flow control is enabled by default and it should not be disabled unless mandatory, because without the hardware flow control the data transmission may not be reliable.
|
||||
If the hardware flow control is enabled from PS-keys, but no flow control is used, the following steps should be implemented in the hardware design:
|
||||
- CTS pin must be grounded
|
||||
- RTS pin must be left floating
|
||||
|
||||
|
||||

include usage-

usage-

|

modes-
|

WD_OFF disabled
|

WD_RST normal reset mode
|

WD_IRQ interrupt only mode (if supported)
|

WD_RST_IRQ interrupt+reset mode (if supported)

timeout-

examples-

WD_SET(WD_RST,WDTO_1S); //reset mode, 1s timeout
|
||||
WD_SET(WD_OFF); //watchdog disabled (if not fused on)
|
||||
WD_SET(WD_RST); //reset mode, 15ms (default timeout)
|

WD_SET(WD_IRQ,WDTO_120MS); //interrupt only mode, 120ms timeout

|

|

|
||||
for enhanced watchdogs, if the watchdog is not being used WDRF should be
|
||||
cleared on every power up or reset, along with disabling the watchdog-

WD_DISABLE(); //clear WDRF, then turn off watchdog
