MMCd Logger New Features and Sensors Archive Latest Information

16-4-05 Posted V1.8g (see below)

Starting this thread to review MMCd bugs and discuss possible new features. I would also like to see if there are other 3SI members interested in doing SW development. (Dev environment is free and takes less than an hour to set up.)

My goal is to periodically summarize feedback / posts on this page.

NEW SOFTWARE FEATURES
1. Auto Logging on Event (cbatters - done)
2. Peak - Hold (cbatters - done)
3. Upload / Convert to CSV (Shawn ????)
4. Address data scaling issues in log files
5. Big Number Mode (TurboBob?)
6. Graphical Gages
7. User Scaling/Config for Custom Inputs
8. User configuration for graph scaling (colors/scaling/offset)
9. User config for all sensors (colors/scaling)
10. User defined log rates / prelog / postlog
11. User defined graphical display time resolution
12. User defined alarm tones
13. Graphical alarm alert

Other suggestions...

HSLogger Project
Interface for adding additional inputs to the MMCd logger. New inputs include:

o Boost (x1) (Using either 2.5 or 3.0 MAP sensor)
o Wideband O2 (x1)
o Oil Pressure (x1)
o Fuel Pressure (x1)
o Intake Manifold Air Temp (x1)
o 0-15V input (x1) (Fuel pump voltage)

o EGT (x1)

o Other
o Vehicle speed (1) and derived calculations
- MPG
- 0-60 timing
- AWD HP

Models / Pricing
Planning to offer three different models of the HSLogger.

HSLogger Base - Fixes baud rate / RS232 level issues to allow compatibility with ALL Palm devices and includes Speed/Odometer input for performance / MPG calculations. You can also log boost with the unused EGRT input. (~$100)

HSLogger Exp - All of the Base unit features plus six 0-5V inputs (Pressure/Boost/Wideband O2 etc from existing sensors/gages - any 0-5V signal) (~$175)

HSLogger Deluxe - All of the Exp unit features plus higher resolution for low level inputs with signal conditioning for direct connection to sensors. Deluxe version has an "analog front end" that provides amplification, filtering, sensor excitation for direct connection to EGT Thermocouples, oil/fuel pressure senders, etc. (~$250)

I believe the Base unit is is competitively priced based on quality passive cables for $75 from Mirage or $150 for PocketLogger SW + Cable. (In my not so humble opinion, MMCd now runs circles around the PocketLogger SW.)

Q1 - What do the letters mean in FLAG0 and FLAG2

Flag 02 status bits
A - Air conditioning relay
F - Fuel pump relay
B - Boost related ???

Flag 00 status bits
T - TDC sensor
S - Power Steering Pressure SW
A - AC switch
N - Neutral
I - Idle switch

Q2 - How do I view MMCd logs on a PC?

MMCd has built in support to upload logs using the Palms archive file capability by simply flagging the log files in MMCd. Files will automatically get uploaded to Palm User - Archive directory on the PC the next time you hotsync.

Simple solution for reviewing logs is to download the PalmSimulator which allows you to run MMCd on the PC. (Just drag MMCd program and log files to the simulator window.)

The other choice is to download MMCdTools which provides a conduit for xfer of logs files as well as conversion of MMCd log format to CSV.

SUMMARY OF CHANGES

KNOWN ISSUES:
Buttons/checkbox controls cause delays in log sampling rate

INVESTIGATION:
Min/Max button
User defined prelog / postlog times
Consider adding default Autolog triggers
Correct slug for EGRT WBO2 inputs - currently hard coded as MAP
Need to confirm Boost solenoid status display
Need to define/implement new log format (mS resolution / Integer / Long / Char )
Scaling for AFR input - Changed in 1.6N
Old 0-5V = 10.0 - 20.0 AFR
New 0-5V = 8.0 - 22.0 AFR
Configurable option for 3S versus DSM mode
- Timing
- Other differences?

What are you using as a development environment? I've been building it under Unix.

Divide / conquer -

I'll send you an email with the right SDKs and a few notes on setting up the environment. (too big to post here)

I'll also put your initials next to Big Numbers Mode!

Stupid question follows ....
How hard would it be to convert
MMCD for use on a laptop?
I've used it in a Palm emulator,
but the sample rate goes way down ..

Not a stupoid question...

Pretty much a rewrite to get this to run natively under Windows. I had toyed with porting it to PocketPC/CE but came to the conclusion that it was not worth the effort given the low cost / availability of cheap Palm devices that are well suited to automotive logging.

Best Wiondows based 1G logger is still probably TMO but it suffers from only a single O2 sensor.

RE: Simulation.
Advise what type of notebook (speed/memory/OS) you were using. I have not run MMCd live using the serial port but I run the simulation for testing and the MMCd UI was much faster on a P3-500 than it was on my Palm V.

NEW AUTO-LOG MODEL
Just tossing out a few ideas for auto-logging mode. My goal is to make it possible to leave auto-logging enabled to catch any events while getting rid of boring "cruising" logs. (Consider a log that only included information when TPS>50% or RPM > 3500)

1. Add auto-log option to alarm UI configuration

2. Add option of silent alarms

3. Any alarm can trigger auto data logging

4. Add user configurable auto-log timer (continue logging for xxx seconds after trigger)

5. Auto-logging on / off control under preferences

6. Manual logging will override and temporarily disable auto-logging

LOW COST SENSORS

Any suggestions on low cost Fuel / oil pressure sensors. Ideal sensor would be 0-100 PSI with a +5 power supply (or unregulated 10-15V) and a 0-5V output.

Would also appreciate input on EGT sensors. Not sure if these are always thermocouples or if some are high terperature RTDs. If we standardize on a particular type of sensor we could include the necessary signal conditioning.

[Storm Strike]

Oil pressure sender: Autometer ATM-2242 $29 from Summit. Might need the metric adapter, as there aren't many places to tap into.

Not sure about cheap fuel pressure senders. Autometer electrical analog fuel pressure gauge/sensor costs almost $200, most of that cost is probably the sensor.

Most EGT probes are thermocouple type, I think.

I'm already installing OP, FP, and EGT gauges, so I'd need to be able to tap into the existing sensors for logging. Everyone else that has already added gauges will too. Not sure how your going to make a universal setup for any type of gauge/sensor combination.

 

[skunkworks]

What about a peak-hold option for boost and o2 or all. Didn't think anyone mentioned it.

Alarms kinda worked for me to check peak - just kept turning the alarm up until it stopped beeping.

#2 under New Software Features on first page. Tapping on the screen will toggle between current data and peak value.

sorry - read over to fast. can't wait! this is going to be great.

I was half expecting somebody to come back and say - we already have that.

Found some 0-100 PSI pressure senders from VDO that can be used for either oil or gas. There is also a conmbo sender / switch that I am investigating as a possible replacement for the existing oil pressure switch assembly.

During you install, please measure the voltage on the OP / FP sensor terminal with respect to ground and advise voltage / PSI relationship.

[cbatters]

Changed scaling on O2 graphs so 1.25V = full scale. (Tired of straining to see O2 voltages)

Also noticed air and coolant graphs are upside down. (Increase in temp was causing graph to go down.)


Clint

 

[cbatters]

Are you distributing the source with the executables as required by the GNU license?

How about a friendlier, less offensive question like"

"Is source code available yet for the enhancements you are contemplating?"


Clint

 

[cbatters]

Adding link at start of thread to current source code to fulfill my GNU obligations. Maybe we can get Zoodled to roll up his sleeves and make the rest of these enhancements.

NOTE:I already contacted Dmitry about adding the changes I made to the standard MMCd distribution. Also provided source code to TurboBob a while ago who is investigating large display characters.


Clint

 

[cbatters]

Clint,
I apologize for my abruptness I do not wish to upset or harm you. It was not meant to be a threat, but a reminder. The executable had been around for a while so I figured you forgot. By the speed by which you posted the file, I figure you had it ready.

I will leave you alone now.
Joe

...sorry for my hyper sensitivity today... your well intentioned comment just struck a raw nerve.

Also sorry to hear that you are punting on the Pocket PC effort. Data logger would benefit from the larger screen of Pocket PC devices.

New communication bridge / input expansion I am working on will at least allow use of some of the latest Palm devices with bigger brighter screens.

Hadn't done an embedded controller project in ~10 years and am amazed by the "Power of the Pic". This entire interface will be 2 chips (14 pin PIC chip + RS232) and a few discrete capacitors / resistors.



Have a good weekend.
