LDS4 Colour Display System
·
Added support for low side driver output on PB20 on LDS4.
05x05 - 22/04/09
·
Added round LED shift lights as an option to the limiter gauge.
05x07 - 27/04/09
·
Added protection against out of range A2DOut indexing.
·
Added short versions of FRAM functions.
·
Removed some spurious code in EventMgr that could theoretically cause erroneous page
selects.
·
Added means of calibrating LDS4 analogues 0 to 3 as sent out on the fast CAN message. This
adds a new event: ET_LDS4_CAL_MODE which toggles the dash between:
1) Not in cal mode
2) In cal mode (moving the analogues logs the min and max values)
3) Program mode (stores the Min and Max in the FRAM and reverts to mode 1
Once calibrated, the transmitted analogues will have a value between 1000 and 2000
although it can fall outside of this range if the calibration is incorrect.
05x08 - 05/05/09
·
Changed the LDS4 fast CAN Tx to send A2 and A3 on words 1,2,3 and 4 of the fast CAN Tx
message.
05v10 - 12/05/09
·
LDS4 calibrated analogues are filtered over 1 sec when in calibration mode.
05x11 - 02/06/09
·
Fixed bug in TimeFilter output that could cause erroneous values to appear at certain update
rates.
·
Add 2ms delay after initialising AMOLED panel to improve boot reliability.
05x12 - 05/06/09
·
Explicitly turn AMOLED panel on as soon as controller has been reset. This fixes a very rare
occurrence of a full white screen on boot.
05x14 - 12/06/09
·
Added message mask support.
05x15 - 26/06/09
·
Fixed bug in OpenScreen and EventGauge that meant Keypad IDs greater than 127 did not
work. This affects setups where a lot of alarms have been added and are used for page
triggers.
05v16 - 07/08/09
·
Added STOP_UNTIL_RESET event to stopwatch. Once received, the stopwatch will not start
running again unless a reset is received first. This works around setups that use a distance (eg
