ALDL Logger
Over the past few months have been making very slow progress on a standalone ALDL data logger. Have finally got a proto built, so far its working ok but have not fully tested it.
The basics of it are...
* SD card logging with FAT16/FAT32 support (There will need to be a flashtool/TP plugin to convert from the raw logged data to a XDL)
* LCD display with live data
* 4 A/D inputs that get shoved into any data stream your recording
* One wire data interface using existing USB comms board with pass through logging (small mod for USB power and firmware updates required)
* TP5 XDF Configuration, the current flashtool connects to read and write the logger cal data (String support and equation support in TP5 are the only issues at the moment)
* USB or vehicle powered for easy bench config
Here are a couple of pics of where its at....

Re: ALDL Logger
wow didn't take you long to get it assembled!!
looks like it will fit nicely into a jaycar plastic box too!
you sure you shouldn't have a bigger sd card in it
bring it on!

No matter what the question is, the answer is always more horsepower!
Just starting out? Have a read of the getting started guide

Your the MAN.
Give VL400 a idea and it turns in to reality.
can't wait to see whats next.

Don't make excuses. Make more horsepower.

Re: ALDL Logger
purely awesome cant wait to see these in action
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem
Re: ALDL Logger
awesome stuff, i had an idea like that i was going to do it with these free MSP430's i have here but i dont yet have the knowledge or time, awesome work VL!! be sure to let us know if/when we can buy em, ill be up for one!

Re: ALDL Logger
Made some more progress with this finally. Took a number of changes as I kept running out of RAM, but it now parses an ADX file stored on the SD card and extracts all the required information for logging and displaying live data (just gotta work out the equation part though). This makes it really easy to configure as you just mod an existing ADX to only define 12 items that you want displayed on the LCD - the entire stream still gets recorded though. Will add flag support later too. Can also save the ADX to EEPROM so it can operate as a ALDL display when no SD card is installed.
But the best part is it also records data to the SD card Its just the raw data stream at this stage but proves the file system support is working. Now need to insert the 4 A/D channels and work out the XDL format so TP can read the file.
