Lab Day

4/17/08
-  Aerocomm transcievers operating correctly, extra transmission due to incorrect "RF Packet Size" in EEPROM settings of transcievers.
-  Connected Receiver to laptop serial port
-  Excel Dashboard can read and log data
-  75% data success rate over RF link

4/15/08
-  Aerocomm transcievers operating, CMD/Data pin must be high for data
-  Scope shows data transfer, then extra 2 byte packet (?)
-  Attempted multiple settings of transceivers to find origin of packet
-  Contacting Aerocomm support

4/10/08
-  MC1489 (RS232->TTL) chip implemented
-  Transcievers don't seem to respond to data sent
-  Going to go over EEPROM settings again

4/8/08
-  Aerocomm Software installed on laptop (SDK & USB drivers)
-  EMAC program working again...finally
-  Somehow lcall for COM port setup was not in the program init file (?)
-  Program does not operate properly, hangs in COM Transmit routine (again????)

4/3/08
-  Went back to program from February and slowly built it back up, finally works
-  Spent all lab period trying to debug/troubleshoot                    
-  Program will not work, even though saved backup was made from last lab period (?????)

4/1/08
-  Tested limits of WinWedge/Excel to data string every 30ms...any faster and Excel can't keep up
-  Macros create for interface with WinWedge
-  Macros created for filling/clearing data log
-  Gave presentation to Speech Coach for critiquing

3/27/08
-  WinWedge software purchased to be used for serial port interface
-  O2 , Air temp, Coolant temp sensor read routines added to software using Pavlik's lookup tables

3/25/08
-  Windmill software not guaranteed to work fully in XP (found in website)
-  Still cannot read through Windmill software

3/13/08
-  COM Port is bad on laptop, too bad it took this long to figure out
-  Continued troubleshooting with serial outputs from micro controller

3/11/08
-  HyperTerminal and Windmill (on laptop) cannot see serial data
-  Troubleshooting serial communication setup

3/7/08
-  Contacting Windmill about issues
-  Admin privileges given for laptop

3/6/08
-  Access rights prohibiting proper operation of Windmill setup
-  XControls Instrument Panel, Excel toolbox that can provide graphic display of car data (free trial)
-  Scrapping SFunction in Simulink, too long to familiarize w/ C code and still implement design

2/28/08
-  Looking into SFunctions in Simulink as another way to accomplish this task
-  After talking with MathWorks support, xPC will not work in this situation
-  Continued xPC troubleshooting

2/26/08
-  Received MathWorks support for setting up xPC target for serial data interface

2/21/08
-  Trying xPC Target to accomplish interface with serial port in Simulink
-  Embedded M-file will not work b/c serial capabilities are stripped from M-code in Simulink
-  Troubleshooting M-file block in Simulink
